Although the earliest H. sapiens fossils are associated with the Middle Stone Age (MSA), lithic technologies considered diagnostic of the MSA have been found alongside Acheulian technology in eastern Africa and the interior of southern Africa by ~ 500 − 400 ka, suggesting a deep evolutionary history of our species in these regions. The southern coastal plain of South Africa, geographically separated from the interior by the Cape Fold Belt and Great Escarpment, has one of the best documented records of the MSA in Africa; however, only a single site is older than 125 ka and little is known about the origins of the MSA in this region. Here, we report a stratified sequence of Acheulian to MSA lithic assemblages from the open-air site of Amanzi Springs covering the period between ~ 379 to 95 ka. We show that the MSA emerged around 230 ± 18 ka, significantly earlier than previously documented along the southern coast. The pattern of technological change also differs to the interior, with no diagnostic MSA elements found in the late Acheulian, although persistent methods of flake production indicate a gradual transition and continuity into the MSA. The relatively late emergence of the MSA along the southern coast highlights the variable and complex nature of demographic and behavioural change during this period, with regionally distinct technological trajectories extending into the Middle Pleistocene in southern Africa.

AU - Harrison, Lauren N. AU - Hurwitz, Shaul T2 - Quaternary Research AB - Abstract Hydrothermal explosions are a significant geological hazard in some active volcanic systems; however, the timing and triggering mechanisms of these explosions are poorly constrained. This study applies luminescence dating techniques to hydrothermal explosion deposits in the Yellowstone Plateau volcanic field to constrain explosion chronologies and evaluate potential triggering mechanisms. We tested four luminescence dating techniques: K-feldspar post-infrared infrared stimulated luminescence (pIRIR 225 ), quartz blue light optically stimulated luminescence (BLOSL), quartz blue thermoluminescence (BTL), and quartz red thermoluminescence (RTL). The pIRIR 225 and RTL protocols produce consistent age estimates that agree with independent radiocarbon ages and with the timing of the Pinedale deglaciation. This study focuses on two craters, Mary Bay, along the northern shore of Yellowstone Lake, and Pocket Basin in Lower Geyser Basin. The mean pIRIR 225 ages from Mary Bay deposits (11.99 ± 0.68 ka) agree with previous radiocarbon constraints. The mean pIRIR 225 results from Pocket Basin deposits (13.44 ± 1.06 ka) suggest a history of explosion following Pinedale deglaciation, followed by recent hydrothermal alteration. Luminescence dating techniques are a promising tool for reconstructing the timing of hydrothermal explosions in the Late Pleistocene and Holocene, helping to constrain recurrence intervals of the largest hydrothermal systems, informing risk, and improving hazard assessments.

These processes were coupled with strong regional climate forcing in SE Asia and its periodicity, reflected by variable precipitation and monsoonal activity occurring in the Intertropical Convergence Zone and being responsible for intensity of denudation as well as characteristics of fluvial processes. Additionally, the increasing human-related environmental imprint was observed since the middle Holocene, being related with extensive melioration, agriculture and urbanization activities. Complex geological and environmental interpretation of sedimentological, geochemical, mineralogical and palynological data was achieved by analysis of several outcrops located in the western and southern part of Hainan Island. Field works were conducted in the lower course sections of Nangang, Tongtian, Zhubi and Baisha rivers, as well as on recent mangrove plains (Danzhou Bay) and Eemian marine terraces nearby Yangpu village. Occurrence of organic rich sediments enabled to conduct AMS 14C dating and to correlate the obtained results with the OSL ages of lacustrine-fluvial strata, which finally enabled to reconstruct environmental changes occurring in the last 130000 years. Presented data inferred different spatiotemporal responses of lower course river sections and mangroves to the local sea level fluctuations in Late Pleistocene-Holocene. Based on a textural features of sediments, geomorphological features of river incisions and chronostratigraphic correlation of the data, six major evolutional stages of lower course river sections were proposed. Geochemical similarities between Holocene organic muds from river outcrops and recent mangrove plains were described, additionally evidenced by an increased proportion of mangrove ferns of Acrostichum, Trespecia and Rhizopora families. Observed exhumation of the older strata was affected by gradual decrease of denudation processes intensity and enhanced incision of flood-plain terraces build of Middle Holocene compacted organic muds. As indicated by the estimation of neotectonic movements, coarse sedimentary material transported by several rivers of western and southern Hainan, influenced formation of “Hainan Delta’, especially during local stages of sea level rise.

T2 - Quaternary Research AB - Abstract Luminescence dating researchers benefit from many community-led software packages. These packages assist with data reduction, statistical modeling, calculation of dosimetric values, and plot production. Yet few resources are simultaneously intuitive, meant for simulating the reduction and growth of luminescence signals, and accessible to non-specialists. The Luminescence Sample Simulator (LuSS) is an application with a graphical user interface that simulates how apparent age and fractional saturation respond to three key scenarios in luminescence dating: sunlight exposure, heat exposure, and burial. Users can simulate these scenarios for an individual cobble or sand grain, or for a population of 100 sand grains. The underlying kinetic parameters can be adjusted manually or taken from a built-in library of published values. Plots of apparent age histograms, luminescence depth profiles, or fractional saturation and apparent age histories are visualized and can be exported. LuSS is written in MATLAB and can operate as a free-to-use, standalone application, or as an app within an existing MATLAB installation. A typical user workflow and three worked examples show how LuSS can model luminescence signal evolution in response to geologic scenarios. Limitations of LuSS include its inability to capture athermal fading or between-grain variability in geologic dose rate or sensitivity.

The Marine Isotope Stage 3 (MIS3) represents a relatively warm period within the Last glacial period, characterized by unstable climate conditions with multiple abrupt changes, similar to the present. The Asian summer monsoon (ASM) has a significant effect on the global climate, and its variations directly affect extreme climates and precipitation. Studying the changes in monsoon precipitation during MIS3 helps to understand the prediction of modern climate changes. This study, based on the analysis of optically stimulated luminescence (OSL) dating of loess in the central Yangtze River watershed, combined with environmental magnetism results, reconstructs the history of monsoonal precipitation changes in the upper-middle Yangtze River watershed during MIS3. The results indicate that the central region of the Yangtze River watershed experienced abundant precipitation during MIS3c, relatively less humid conditions during MIS3b, and a more humid pattern during MIS3a. The integration of other climatic forcing characteristics during MIS3 indicates that the variation of the East Asian summer monsoon (EASM) caused by the difference in the pressure gradient between land and sea under the regulation of solar radiation variations at low latitudes in the Northern Hemisphere is the main driving force for the dry and wet changes in the Yangtze River watershed, and the Indo-Pacific warm pool effect (IPWP) is the main source of the humidity changes in the watershed.The variations of the EASM and the strength of the IPWP effect are the primary cause of the 'humid-less humid-humid' characteristics in the hydrological changes of the Yangtze River watershed and their adjacent regions during the MIS3 stage. • Variations in local hydrology during MIS3 were reconstructed in Yangtze River watershed by loess sediments. • During the MIS3, three stages of 'humid-less humid-humid' characterize climate in East Asia. • Humidity changes in East Asia were positively related to EASM during the MIS3. • Sea-land thermal contrast and water vapor transportation regulated humidity changes.

In this study, laboratory friction experiments were performed to simulate the influence of seismic slip rates on rock luminescence signals. High-speed friction generated rapid heating of the frictional interface, with temperatures reaching 500–800 °C. This process effectively reset the infrared-stimulated luminescence (IRSL) signal within the upper ∼1.5 mm of gabbro surfaces, and fully reset the signal up to ∼6 mm inward from surface edges. However, depth information was partly lost because mechanical cutting caused local detachment of thin rock slices. To overcome this limitation, we measured luminescence signals using the Risø luminescence imager, which provides non-destructive and high-resolution IRSL and Infrared Photoluminescence (IRPL) measurements on granite samples. The lack of preheating may preserve some unstable charges and slightly underestimate the resetting ratios. Even so, the patterns are robust. High-speed friction eliminated ∼99 % of IRSL intensities and reset 78 ± 1 % of the IRPL955 signals. Low-speed friction reset 83 ± 1 % of the IRSL signals and had only 29 ± 1 % of IRPL955 signals. These results confirm that the Risø luminescence imager is highly effective in detecting friction-induced signal resetting. The non-destructive imaging approach preserves depth information and offers higher spatial resolution than measurements on cut rock slices. IRSL and IRPL955 signals can potentially constrain the timing of high-velocity seismic slip. Their contrasting responses to different slip conditions may also reflect deformation processes associated with stick-slip and creep, providing additional insight into earthquake behavior.

We assess small-aliquot quartz optically stimulated luminescence (OSL) and feldspar infrared-stimulated luminescence (IRSL) dating of glaciofluvial, glaciodeltaic, and aeolian sediments against a well-established soil stratigraphy and a cosmogenic 10 Be depth profile. Results indicate that standard blue-light OSL regenerative protocols used on MIS 2 glacial sediments in the region warrant caution when duplicated for MIS 6 sediments. Quartz OSL ages underestimate age by up to 50% compared with cosmogenic and feldspar post-IR IRSL 200 ages. Presence of unstable or hard-to-bleach OSL signal components that cannot be removed with modified preheat protocols yields unreliable data. While dates obtained using post-IR IRSL 200 protocols on feldspar are affected by partial bleaching and anomalous fading, these factors can be accounted for. Discrimination of negligible-fading small-aliquot data allowed us to obtain post-IR IRSL 200 ages between 103 ± 12 and 241 ± 28 ka. Post-IR IRSL 200 ages are mostly consistent with 10 Be depth-profile dating and stratigraphic constraints and represent a viable option to study glaciofluvial sedimentation during MIS 6 and older glaciations in the region.

The cave's infill reflects a non-continuous, multi-phase sedimentary history shaped by both natural and potentially anthropogenic processes. Through an integrated multidisciplinary approach, combining micromorphology, radiocarbon and OSL dating, paleontology, anthracology, and ancient DNA studies on fossil voles, this study reconstructs the chronological, paleoenvironmental, and paleoclimatic framework of the site. The stratigraphic sequence reveals alternating phases of slow accumulation, erosion, and redeposition, with weak anthropogenic inputs in the lower units. Faunal assemblages dominated by small mammals, birds, and molluscs reflect significant climatic oscillations between Marine Isotope Stage (MIS) 5 and MIS 2/1, with shifts from mainly temperate to cold-adapted taxa. The presence of charcoal may also indicate episodic fire activity, probably of natural origin. The stratigraphic complexity of Łabajowa Cave provides a valuable record for reconstructing the interactions between sedimentary dynamics, climate variability, and faunal changes during the Late Pleistocene in Central Europe.

The protocol provides an opportunity for measuring polymineral samples as violet stimulation prior to IRSL measurement, bleaches natural luminescence signal of quartz, and makes it possible to probe photo-transferred charges in feldspar through IR stimulation. This study presents the results of the pVIR-SAR protocol on natural polymineral fine- (4–11 μm) and coarse-grain (90–150 μm) samples, including volcanic ash, pottery, and fluvial deposits from varied geological provenances. The results show that pVIR-SAR ages of both these fine- and coarse-grain samples are consistent with geological reasoning and available age controls thereby suggest that with the use of the pVIR-SAR protocol, mineral separation can be dispensed. This study also reports on the bleachability, athermal fading rates, and alpha efficiencies of pVIRSL for these samples and corresponding results are compared with IRSL at 50°C and post-IR IRSL (pIRIRSL) at 290°C. The pVIRSL signal has a better bleachability and reproducibility compared to the pIRIRSL signal. For the fluvial deposits dated in this study, the fine-grain samples provide ages consistent with the expected chronology.

T2 - Quaternary Science Reviews AB - Environmental drivers were likely key to human dispersals from Africa into and throughout Eurasia, but the effect of such drivers on human biogeography has yet to be resolved at high-resolution on a regional scale. Here, we probe the Levantine-Arabian region for environments favourable to human forager groups around 50 ka when a demographic wave surged across Eurasia imprinting the ancestry of all non-Africans living today. We present a set of 33 optically stimulated luminescence dates demonstrating more than 50,000-years of persistent riverine wetlands on the eastern margin of the Jordan Rift Valley at Hamra Faddan and Wadi al-Hasa—the latter hosting stratified Middle Palaeolithic artefacts indicative of frequent human presence. By reviewing and combining multiple climate proxy records, our analysis reveals permanent surplus moisture existed across much (∼70,000 km2) of the southern Levant during the interval 70–40 ka, in contrast to surrounding regions such as interior Arabia where intensified aridity and a paucity of archaeological sites primarily suggest landscape abandonment. We propose that the southern Levant offered a relatively stable, favourable environment for foraging human populations extending to the Upper Palaeolithic, during which time the region was a crucible for fostering human admixture, knowledge sharing and technological evolution. The southern Levant likely functioned as one of several population and cultural hubs in Southwest Asia during the Late Pleistocene.

The chronological extent of this behavior is constantly moving back in time; currently, the oldest evidence has been identified at the Bizmoune cave site in Morocco back to the MIS 6. Although these evidences make it possible to refine the spatial and temporal distribution of this behavior, shell beads remain rare in Middle Stone Age assemblages and are generally composed of several beads, or at best dozens, for each of these sites. This restricts our understanding of the behaviors specifically related to the collection, selection and preparation phases of shells, and potentially limits our understanding of their use. In this article, we studied shell beads from MSA layer US 8 from the coastal archaeological site of El Mnasra Cave (Rabat-Témara, Morocco). This collection corresponds to the largest MSA shell bead assemblage in Africa (272 Tritia cf. gibbosula, 6 Tritia corniculum and 3 Columbella rustica in US 8 with 154 of them showing smoothing of the perforation edge, facet of abrasion, or traces of pigment). The shell bead assemblage of El Mnasra presents features previously observed at other MSA sites, connecting it to a North African cultural context; however, the size of the El Mnasra shell bead assemblage, and the presence of shell sources near the site, allows us to identify specific features that could be related to particular modes of use as ornaments. These specific features include the prevalence of un-perforated shells, some of which show use-wear, that could have been fixed on items without having been perforated. These results provide new insights into the wide range of variants and originalities of shell bead uses over a relatively "short" chronological phase, between 115 and 94 ka and can be correlated with the multistep evolutionary scenario proposed for South Africa. The archaeological documentation presented here shows that El Mnasra Cave provides a significant contribution to the study of culturing the Palaeolithic body in North Africa.

Despite this, the paucity of well-dated Pleistocene archaeological sites from Sulawesi means that very little has been known about the pattern and timing of early human occupation of the island, including whether there is any evidence for overlap between archaic hominins and modern humans, and when and how the former went extinct. Here, we report the results of multiple seasons of deep-trench excavations at Leang Bulu Bettue, a limestone cave rock-shelter complex in the Maros-Pangkep karst region of South Sulawesi. Leang Bulu Bettue is the only site presently known on the island with an archaeological record ranging in age from the Middle to Late Pleistocene to late Holocene periods. Investigations at this site since 2013 have revealed an extensive sequence of stratified deposits down to a depth of about 8 m below the surface. Notably, there is evidence for animal butchery and stone artefact production including a stone 'pick' at around 132.3-208.4 ka followed by a major shift in human cultural activity during the Late Pleistocene. By around 40 ka, an earlier occupation phase (Phase I) characterised by a straightforward cobble-based core and flake technology and faunal assemblages dominated by extant dwarf bovids (Bubalus sp., anoas), but including now-extinct proboscideans, had been replaced by an entirely new occupation phase (Phase II) with a markedly distinct archaeological signature, including the first evidence for artistic expression and symbolic culture. We consider the implications of this behavioural disconformity for our understanding of the history of humans on Sulawesi, including the possibility it reflects the replacement of archaic hominins by modern humans.

The results show that: (1) The chronostratigraphic framework of the TKGC section is as follows: aeolian sand (15.5–13.6 ka BP)— aeolian loess (13.6–8.5 ka BP)—paleosol (8.5–3.0 ka BP)—recent loess (3.0–1.3 ka BP)—topsoil (1.3–0 ka BP). (2) Consistent with previous understandings of global climate change, the loess and paleosol sequences in the alpine Zoige basin also reflect varying intensities of weathering and pedogenesis during different periods. Sedimentological, geochemical, and micromorphological evidence consistently indicate strong pedogenesis during the paleosol development, while pedogenic processes were weak during periods of aeolian sand and loess accumulation. (3) Following the disappearance of the paleolake, from 15.5 to 13.6 ka BP, the region experienced harsh climatic conditions and intense aeolian activity, leading to the deposition of coarse-grained aeolian sand. Around 13.6 ka BP, aeolian activity declined, resulting in the accumulation of finer-grained aeolian loess. By 8.5 ka BP, the regional climate shifted from cold and arid to warm and humid, initiating the development of the paleosol. Around 3.0 ka BP, climatic conditions reverted to colder and drier states, enhancing aeolian processes and facilitating the formation of the recent loess layer. Subsequently, around 1.3 ka BP, the topsoil began to form atop the recent loess deposits.

AU - Bretzke, K AU - Kim, S AU - Jasim, S A AU - Yousif, E AU - Preusser, F AU - Preston, G W AU - Pallottino, F AU - Parker, A G T2 - Nature communications AB - Several significant milestones in human evolution date to the period between 70,000 and 12,000 years ago, including the replacement of archaic humans, the global dispersal of Homo sapiens and the introduction of Upper Palaeolithic traditions. The Arabian Peninsula provides only sparse records illuminating this period. We introduce here the Buhais Rockshelter archaeological sequence and paleoenvironmental records from the Faya Palaeolandscape in the Emirate of Sharjah (UAE). Buhais Rockshelter provides stratified stone artifact assemblages reflecting habitation phases around 125,000, 59,000, 35,000 and 16,000 years ago. Palaeoenvironmental fieldwork further shows that settlement at Buhais Rockshelter is contemporaneous with increased water availability in the landscape at these times. Our results contradict the prevailing view of human absence in Arabia at the end of the Pleistocene and call for reassessing the inhabitability of southern Arabia during the last glacial period. Results from Buhais Rockshelter extend known records from Jebel Faya and demonstrate repeated occupation of the region between 210,000 and 16,000 years ago. Together, this contributes data for a critical timeframe in human evolution providing an empirical foundation for testing anthropological models about human adaptation to and dispersal through the desert landscapes of southern Arabia.

Both methods rely on subaqueous resetting (bleaching) of luminescence signals by light. Differences in bleaching between grains and/or luminescence signals encode information on the light exposure history of individual grains and therefore yield information on past sediment transport. Here we assess the potential of multi-signal single-grain feldspar luminescence to inform about sediment pathways at Ameland tidal inlet in the Dutch Wadden Sea. We also tested whether nourished and native sands can be distinguished based on their luminescence signals. Single-grain infrared stimulated luminescence (IRSL50) and post-IR IRSL (pIRIR) were measured from samples collected from modern sea-floor deposits across the inlet. Equivalent dose (D e ) distributions were assessed using the Central Age Model (CAM), and bootstrapped versions of the Minimum Age Model (bMAM) and Maximum Age Model (bMAX) were applied to the IRSL50 D e distributions. Spatial trends in CAM and bMAX-De reveal highest inherited doses at the tip of Ameland in the Borndiep channel, decreasing along transport pathways around the ebb-tidal delta. These patterns indicate erosion of Pleistocene sediments in the Borndiep channel and progressive bleaching of luminescence signals upon transport. Low D e values in shallow areas reflect repeated reworking of Holocene sands within the active layer. Nourished and native sediments show indistinguishable luminescence characteristics for our dataset due to their shared Holocene origin. • Multi-signal single-grain luminescence applied for the first time in a tidal inlet. • Spatial bleaching patterns derived from equivalent dose model analysis. • Luminescence data reveals sediment transport pathways in the Ameland inlet. • IRSL and pIRIR signals cannot distinguish nourished from native sands.

T2 - Journal of Quaternary Science AB - ABSTRACT The climate history of the major dryland zones of the world, such as the Saharo–Arabian Desert belt, plays a key role in the dispersal of early humans through these intermittently inhospitable regions. Here, we assess the relative intensity of Late Quaternary humid phases in northern Arabia through lithological, geochemical, palaeoecological and geochronological analysis of three sediment sequences in the Nefud Desert. Two sequences are marl beds that accumulated in perennial, groundwater‐fed lake systems during two distinct humid phases that occurred in MIS 5e and MIS 5a. The third records sediment accumulation within an ephemeral lake system during the terminal Pleistocene/early Holocene. The altitude of the two MIS 5 deposits indicates that the water table must have reached altitudes of >929 m ASL (MIS 5e) and >922 m ASL (MIS 5a). In contrast, the sedimentary characteristics of the early Holocene sequence imply that, during this interval, the water table was <917 m ASL. These results indicate that, in relative terms, the humid phase of the Holocene was significantly drier than other Late Quaternary humid phases, a conclusion that is consistent with a growing body of evidence from across the Saharo–Arabian Desert belt. These findings are discussed relative to human dispersal/occupation and palaeoclimatic conditions in northern Arabia during Late Quaternary humid phases.

AU - Wallinga, Jakob T2 - Journal of Archaeological Science AB - Celtic fields are prehistoric field systems characterised by rectangular plots enclosed by earthen banks, which are widespread across northwestern Europe. They are assumed to have emerged between the final stages of the Middle Bronze Age and the Early Iron Age in continental Europe, but firm chronologies based on radiometric dating (e.g., 14 C, luminescence) are sparse, hampering the interpretation of age and formation process. This leads to contrasting interpretations and unexploited potential of the systems to inform on societal transformations. This study focuses on luminescence dating and aims to develop a suitable luminescence dating procedure that can provide robust dates for the construction and raising of Celtic field banks. To achieve this, we sampled two banks in two Celtic fields in the Netherlands (Vaassen and Zeijen) in a systematic manner with high-resolution. We applied small-aliquot quartz optically stimulated luminescence (OSL) and single-grain feldspar post-infrared infrared stimulated luminescence (pIRIR) measurements. The systematic high-resolution sampling proved to be an effective sampling strategy that can provide detailed chronological information. Both quartz OSL and single-grain feldspar pIRIR provided consistent and reliable reliable dates for the time of construction and raising of the banks. Single-grain feldspar pIRIR analysis provided additional information about the formation process of the banks and bleaching history of the deposited material, but also demonstrated potential limitations in universal application. The dating results demonstrated that both investigated Celtic field banks were constructed in the Dutch Middle Bronze Age and have been gradually raised until the Dutch Roman Age. At Zeijen we documented a period of rapid raising of the bank in the Dutch Late Iron Age. • Systematic high-resolution sampling combined with multiple luminescence analysis is effective for reconstructing Celtic field banks. • Quartz OSL and single-grain feldspar pIRIR yield reliable ages. • Single-grain feldspar pIRIR luminescence dating can provide additional information on the formation process. • The two investigated Celtic field banks from two systems in the Netherlands were initiated in the Dutch Middle Bronze Age and raised until the Dutch Roman Age.

Through a signal stability experiment carried out on two quartz samples, we evaluated the evolution of the Al and Ti ESR signal intensities over 2 to 8 months after gamma-irradiation. Our results indicate that the variation of the ESR intensities remains within typical experimental uncertainties, although data might also suggest a potential trend during the first day after irradiation. This trend is, however, non-systematic and could be sample- and signal-dependent, if not directly related to the stability of the experimental setup. Regardless, for precaution we may nevertheless recommend waiting for 1 day after gamma-irradiation before carrying out the ESR measurements. Importantly, this finding implies that ESR measurements of quartz samples can be performed relatively soon after gamma-irradiation, enabling the implementation of more time-efficient SAR protocols for ESR dating applications.

Understanding the dynamic evolution of distinct dune hierarchies is crucial for unraveling their formation mechanisms. However, establishing a robust chronological framework for young dunes has consistently hindered investigations into the surface landscape dynamics of the megadunes. In this study, we employed optical dating methods to determine the chronologies of young dunes on the surface of the megadunes. Our results demonstrate that the K-feldspar pIRIR test method effectively overcomes the challenge of dim signals from quartz grains in young dunes, enabling the reliable dating of subordinate dunes on the megadunes in BJD. The subordinate dunes were predominantly formed during the Little Ice Age (LIA; 1400–1900 CE) and the Current Warm Period (CWP; 1900 CE-present). The fluctuating Westerlies and the East Asian Monsoon (EAM) climate systems jointly influenced the recent geomorphological landscape of the megadunes in BJD. Additionally, our chronology indicates that the megadunes are increasing in height while simultaneously undergoing lateral expansion. The findings provide a comprehensive account of the evolutionary dynamics of the geomorphological landscape of the world's tallest megadune complex and offer a substantial theoretical foundation for further elucidating the formation mechanism of the distinctive megadune and lake coexisting geomorphology observed in the BJD.

The Longchuan River in central Yunnan Province is a first‐level tributary of the southern bank of the Jinsha River, and its basin is a standard watershed zone of the Red River, Jinsha River, and Pearl River. This basin is a sensitive area for the evolution of large river systems. Consequently, this region offers an optimal setting for investigating the coupling relationship between tectonic activity, climatic variations, and river system evolution. In this study, optically stimulated luminescence (OSL) dating and identification of heavy minerals and palynology were conducted on the newly discovered river terrace sediments of the Longchuan River. The results indicated the following. (1) The Longchuan River began to develop during the late Quaternary, and the sedimentary periods of three terraces (T2, T1, and T0) in the middle Yuba area were 69 ± 1.2 ka, 54 ± 3.9 ka, and 5.6 ± 1.3 ka, respectively. The deduced downcutting rates are 0.40–0.42 mm/a, 0.18–0.21 mm/a, and 0.28–0.46 mm/a, are lower than those of the Jinsha River to the north, indicating that the crustal uplift in the Longchuan River Valley is weaker than that in the Jinsha River Valley. (2) Since the late Pleistocene, the vegetation in the Longchuan River Basin have been represented by Pinus , Betula , Ilex , Theaceae, and other mixed forests with fern growing under the forest, reflecting a regional climate that has become increasingly hot and humid. (3) During the T1 to T0 deposition period, the headward erosion direction of the upper reaches of the Longchuan River gradually evolved from the Shiguanshan area to the Tianzimiaopo area. (4) The Longchuan River system may have inherited extinct Quaternary lake basins in the region, with its development and evolution possibly influenced by tectonic faults as well as climatic factors. This study elucidates the detailed processes and mechanisms of river system evolution at the plateau margin under the coupled driving forces of tectonic activity and climate change. It provides a key case study for understanding the dynamics of the geomorphic system in the southeastern Tibetan Plateau, offering significant value for advancing the theory of tectonics‐climate interactions and predicting future regional environmental evolution trends.

Consequently, understanding its kinematic history is important for studying the dynamics of the Eastern Alps, in particular the Tauern Window. However, the timing of fault activity remains debated. Based on low‐temperature thermochronometry, it has been proposed that the fault has not moved since approximately 9 Ma. However, recent seismicity suggests that it is still active. We bridge this time gap by applying electron spin resonance (ESR) dating on quartz. This ultra‐low temperature thermochronometer has a closure temperature of 80–50°C and therefore enables the study of the most recent footwall exhumation. Our ESR thermochronometric ages obtained from the Brenner area ranged from 0.38 ± 0.02 to >3.34 ± 0.63 Ma. The lateral distribution of these ages suggests that exhumation was caused by a combination of tectonic activity and glacial/fluvial erosion over the last million years. Exhumation occurred mostly within the first 500 m of the footwall of the Brenner Fault. Using 2D thermokinematic inverse modeling, constrained by the ESR data, we estimate the movement on the fault to a slip rate of 3.0 ± 0.7 mm/yr over the last million years. Our results, together with previous data, imply that the Brenner Fault has been almost constantly active for 19 Ma until the present‐day. , Plain Language Summary The Brenner Fault in the European Alps is a large fracture in the crust along which rocks were moved over a long distance, when the Alpine mountains formed. However, it is not known whether the fault has been silent for millions of years or has been active since its formation. We took samples from both sides of the Brenner Fault, as well as from the fault itself. We used a method called electron spin resonance (ESR) to find out whether the fault was active in the recent geological past. The method is sensitive at low temperatures compared to other methods and therefore we are able to study the geologically recent landscape development, and in particular, recent movement on the fault. We obtain ESR ages between 380 thousand years and greater than 3.3 million years. This suggests that the rocks were brought to the Earth's surface by a combination of movements along the fault and erosion of the rocks. Furthermore, combining the data with other parameters in a model suggests that the fault has moved at a rate of ca. 3 mm per year over the last 19 million years. , Key Points First measured electron spin resonance thermochronometric ages from the Brenner Fault in the European Alps suggest Quaternary movement Thermokinematic modeling yields a slip rate of 3 mm/yr for the Brenner Fault in the Quaternary DA - 2026/03// PY - 2026 DO - 10.1029/2025GC012484 DP - DOI.org (Crossref) VL - 27 IS - 3 SP - e2025GC012484 J2 - Geochem Geophys Geosyst LA - en SN - 1525-2027, 1525-2027 UR - https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2025GC012484 Y2 - 2026/04/07/11:14:29 ER - TY - JOUR TI - Climate‐driven alluvial fan aggradation and incision in an unglaciated Himalayan basin, Northwestern India AU - Chauhan, Vaishanavi AU - Mandal, Sanjay Kumar AU - Scherler, Dirk AU - Panda, Swagat Kumar AU - Das, Sourojita AU - Christl, Marcus T2 - Earth Surface Processes and Landforms AB - Summary Remnants of thick alluvial fills in Himalayan valleys and intermontane basins record past disruptions in sediment routing. However, the climatic drivers of these aggradational phases remain debated. Do they reflect enhanced hillslope sediment supply during intensified monsoon phases, or reduced fluvial transport capacity under drier conditions? To address this question, we analyze an 55‐m‐thick late Pleistocene alluvial fan succession deposited in the structurally confined Pinjore Basin of the Northwestern Himalaya, sourced from an 350‐km 2 unglaciated catchment. Using optically stimulated luminescence dating and in situ 10 Be measurements from buried sediments, we reconstruct the timing of fan deposition and catchment‐scale paleo‐erosion rates to assess links between monsoon variability, sediment supply and fluvial transport capacity. Fan aggradation persisted for 39 kyr between 52 and 13 ka, coinciding with the prolonged weakening of the Indian Summer Monsoon. Low and relatively stable erosion rates throughout most of this interval suggest that aggradation was primarily driven by reduced runoff and limited fluvial transport capacity, rather than increased sediment supply. After 26 ka, declining sedimentation rates, sediment coarsening and lower inherited 10 Be concentrations may reflect reduced slope stability due to vegetation changes associated with glacial cooling. Renewed fan incision after 13 ka coincides with monsoon strengthening, indicating a shift toward increased transport capacity. These results highlight a climate‐sensitive, threshold‐controlled sediment‐routing system in which changes in runoff and vegetation drive aggradation–incision cycles. The Pinjore Basin record underscores the potential for nonlinear fluvial responses to hydroclimatic variability in tectonically active mountain landscapes.

Lyoluminescence is a phenomenon occurring during the dissolution of previously irradiated material. Measurements facilitate the estimation of the total dose absorbed by the material since its last exposure to light, heat, or moisture. Due to its versatility, LyoScope is suitable for both environmental and laboratory measurements. Its elementary design enables self-assembly, such as through 3D printing. We provide a detailed technical description and present first performance tests: the minimum detectable dose for NaCl was determined at ∼5 mGy, repeatability tests on natural halite achieved a variation of only ∼2.4 %, and fading experiments revealed that ∼35–40 % of the LL signal is lost within weeks, followed by stabilization of ∼35–60 % of the signal. In addition, we demonstrate the option of attaching an EM-CCD camera to our setup enabling spatially-resolved LL measurements and a visualization of the dissolution process. Our results underscore that LyoScope enables reproducible LL measurements and support the potential of LL as a complementary tool for dosimetry and geochronology.

T2 - Radiation Measurements AB - In the aftermath of a nuclear or radiological incident, rapid and reliable dose assessment is critical for medical triage, exposure evaluation, and emergency management. This study investigates the use of household salt with portable Optically Stimulated Luminescence (OSL) systems as a potential dosimetry system to enhance methods for mapping radiation fields with data available during the measurement period. Previous studies have shown that unprepared commercial salt demonstrated a linear dose response in the 0–500 μGy range, with detection limits as low as 7 μGy using portable OSL. Signal stability studies revealed an initial brief decrease in luminescence post-irradiation, followed by relative stability between 8 and 64 days, enabling dose estimation during early and late emergency phases. Light and moisture caused rapid signal loss, which was mitigated by encapsulating sachets of salt in sealed heat-shrink sleeving. In this work, three experiments were conducted to confirm salt's utility. Controlled lab tests mapped the radiation field in close proximity to a known activity 60-Co source. A dosimetry array was used outdoors at SUERC, in combination with portable gamma ray spectrometry, to map background radiation with and without a source present. Thirdly a network of dosimeters was used to map the complex and time varying radiation fields within an accelerator mass spectrometry laboratory at SUERC. In the controlled lab experiment, fading-corrected doses matched theoretical inverse-square values within <3% on average. In the outdoor experiments average dose rates agreed with backpack gamma measurements within 3–15%. In the accelerator laboratory the salt effectively separated the spatial variations in the local radiation background of the laboratory from those associated with enhanced radiation during beam alignment and tuning operations. Results thus aligned with theoretical doses, gamma-system measurements, and the configuration of radiation fields within a complex laboratory confirming salt's potential for low-dose dosimetry and spatial field mapping. Protocols for fading correction, ambient conditions, and zeroing are essential for practical deployment. The work presented here has demonstrated that the field validation of using salt with portable OSL systems is capable of delivering dose estimates in the range from a few μGy to several mGy in field measurements, complementing existing techniques. To optimize this approach, comprehensive protocols should be developed for both testing exercises and evaluations, which could lead to wider acceptance of these approaches offering a robust, low-cost solution for rapid dose assessment for both emergency response and environmental dosimetry.

The NAUTILUS also allows for nanosecond time-resolved PL or OSL measurement using pulsed lasers or diode light sources. These measurements can be carried sequentially on up to 48 samples without the need to move the samples between instruments, thus improving both measurement reproducibility and throughput. The aim of this contribution is to demonstrate the capabilities of the NAUTILUS using well-known dosimetric materials, such as Al2O3:C,Mg, Al2O3:C, MgB4O7:Ce,Li, and Ag+-doped phosphate glass. By doing so, we demonstrate the NAUTILUS’ capability to perform in-situ irradiation, heating, and reliable advanced luminescence measurements, sequentially on up to 48 samples, with results in agreement with those reported in the literature.

The red thermoluminescence (RTL) protocol has emerged as a promising alternative, taking advantage of the strong TL emission of SMD components in the near-infrared spectral range. The present study investigates the dosimetric performance of red thermoluminescence (TL) emission from surface-mounted devices (SMDs) and its potential for use in accident dosimetry. Key characteristics, such as intrinsic zero-dose signal, signal reproducibility, dose-response relationship, signal stability, and a dose recovery test, were systematically analysed. An irradiation experiment was conducted in which SMDs were exposed to 6 MV X-rays using LINAC, and subsequent dose reconstruction was carried out employing the RTL protocol. The experiments demonstrated that a new RTL protocol yields promising signal intensities, and successful dose reconstruction was achieved even after delayed readout, with fading corrections applied. Dose estimates obtained from single SMD resistors, both reference components and those extracted from a smartwatch, showed good agreement with reference dosimeters, with overestimations between 5 % and 24 %. These findings confirm that the RTL method includes sufficient sensitivity and the ability to analyse very limited sample quantities, particularly in scenarios where signal sensitivity is critical.

T2 - Quaternary Science Reviews AB - We provide new numerical age constraints to the Plio-Pleistocene section of Dhar Iroumyane (Morocco) and the associated fossil locality of Guefaït-4, which has yielded an exceptionally rich and diverse faunal assemblage, through a combination of Electron Spin Resonance (ESR) and Terrestrial Cosmogenic Nuclides (TCN) dating of quartz. While challenging in many aspects, the application of these dating methods to the same deposits located about 5 m below the fossiliferous horizon returns consistent numerical dating results within respective uncertainties. More specifically, the age overlap enables to propose a combined ESR-TCN age of 2.87 ± 0.11 Ma (1σ), which may be regarded a maximum age constraint for Guefaït-4 from a chronostratigraphic point of view. These results allow us to narrow down the options of chronological interpretation proposed in a previous study by Parés et al. (2023), by supporting a correlation of the magnetic reversal initially identified a few meters above the site to the Gauss-Matuyama transition (2.61 Ma). A final age estimate of ∼2.7 Ma may be inferred for the fossil horizon through a series of sensitivity tests based on sedimentation rates. With this approach, the normal polarity interval identified in the upper part of the sequence is most likely correlated to the Olduvai Subchron (1.93–1.78 Ma), and the two short reversals in the lowermost deposits with dominantly normal polarity may be reasonably associated to the intra-Gauss Mammoth (3.33–3.21 Ma) and Kaena (3.12–3.03 Ma) Subchrons. Consequently, the present work help position Guefaït-4 as a key Late Pliocene fossil locality in N Africa for the establishment of a robust regional Plio-Pleistocene biochronology, although further work is required in the future to increase the chronological resolution along the sedimentary sequence. While we do acknowledge the intrinsic uncertainty associated with the ESR and TCN dating results (including the limited number of samples processed in the present study), these encouraging results nevertheless illustrate the interest of using a multi-technique approach to constrain Plio-Pleistocene deposits, and the importance of combining numerical dating with magnetostratigraphy and biostratigraphy/biochronology in non-volcanic sedimentary context. Such approach also contributes to a better understanding of the potential and limitations of each dating method, and helps providing critical insights into the avenues worth exploring in the future from a methodological and sampling point of view in order to ensure future successful ESR and TCN dating applications beyond 2 Ma.

T2 - Journal of Archaeological Science: Reports AB - Eastern Africa is a key region for studying the origin and dispersal of early Homo sapiens. In particular, in the Lake Eyasi basin located in northern Tanzania, Mumba Rock Shelter yielded a long stratigraphic sequence documenting lithic assemblages from the Middle Stone Age (MSA) and the Later Stone Age (LSA). The site was excavated by Margit Kohl-Larsen in 1934 and 1938. Despite having been the object of multiple dating studies, the chronology of Bed V, attributed to the MSA, was poorly defined. This work presents new ages obtained using Electron Spin Resonance (ESR) dating combined with uranium series (230Th/U) on eight herbivore teeth from Bed V of the MSA, selected from the Kohl-Larsen collection curated at the University of Tübingen in Germany. Following the 2022 excavation campaign, we were able to correlate the initial location of the teeth discovered in the 1930s with the standing section and reconstruct the environmental dose rate with in situ gamma spectrometry measurements. The ages, ranging from 72 ± 8 ka to 54 ± 3 ka, fall within marine isotopic stage (MIS) 4 and the beginning of MIS 3, framing the human occupation recorded in Bed V during the Late Pleistocene.

There is a growing body of research focused on the behaviour of the Indo-Australian Summer Monsoon (IASM) during these periods from sites close to Australia’s northern coastlines and currently within the zone of direct monsoon precipitation. However, the relative contributions of latitudinal shifts and/or moisture carrying capacity of the monsoon system on changes in hydroclimate remain uncertain. Here, we present the results from a 46,000-year sediment record obtained at the modern southern extent of rainfall penetration into north-west Australia associated with the IASM. Our results show that the region experienced reduced precipitation until the end of the glacial. During the MIS 2/1 transition and the early Holocene, there is evidence of an increase in wet-season precipitation, likely limited to extreme events occasionally reaching the site. More pronounced and sustained shifts in precipitation were limited to the late Holocene, during which the variability recorded at the site aligned with that interpreted from records further to the north in Australia. We interpret this as reflecting a time-transgressive southward shift in the southern limit of the monsoon system.

AU - Costa, Sophie AU - Purdue, Louise AU - Djerbi, Hatem AU - Davtian, Gourguen AU - Carré, Alain AU - Rouvier, Claude AU - Garberi, Pauline AU - Sipos, György AU - Preusser, Frank T2 - Quaternary Science Reviews AB - In south-eastern Arabia, climatic reconstitutions mainly derive from the study of speleothems, dune sands, lacustrine deposits, and alluvial sediments. In the Hajar Mountain range, which covers a major part of SE Arabia, the Late Quaternary is relatively poorly documented, notably due to the lack of preserved archives. We explore the potential of oasis soil sequences as archives of past landscapes and climate in the Emirate of Ras al-Khaimah, in the piedmont oases of Dhayah, Sir, and Jiri. Geomorphological surveys, mapping and geoarchaeological investigations combined with luminescence and radiocarbon dating were conducted in these oases. We propose a detailed typology of the deposits and provide a first interpretation of their origin and depositional modes (alluvial, aeolian, anthropogenic). Our results show that Holocene agricultural activity has preserved natural archives from deflation and alluvial erosion. This allows us to identify phases of aeolian reactivation during Marine Isotope Stage (MIS) 4 (∼65 ka) and MIS 2 (∼21 ka), whereas alluvial sedimentation occurred in early MIS 3 (∼54 ka), the Late Glacial (∼15 ka) and the early Holocene (∼8-6.5 ka). Two important shifts of active lobe and distal incisions were identified in the Sir plain between 9-8 ka and 6-3.5 ka and potentially linked with base level evolution and/or climatic changes. Oases development is recorded during the second half of the Holocene. Despite a voluntary control of water supply, we identified phases of alluvial reactivation between ∼3.5 and 3 ka and ∼1.3 and 1 ka, and intense fluvial detritus dated to ∼2.7-2.4 ka. This study demonstrates that oasis pedo-sedimentary sequences in arid environments are valuable archives for the reconstruction of climatic conditions and landscapes evolution.

AU - da Conceição, Fabiano T. AU - Lana, Claudio E. AU - Moreira, Vinicius B. T2 - Quaternary International AB - Climatic changes and tectonic events play an important role into the denudational and sedimentation processes. The Southern Espinhaço Range (SER) is an important N-S continental elevate terranes in the state of Minas Gerais, Southeastern Brazil. The SER is primarily composed for Paleo-Mesoproterozoic quartzites, with Neoproterozoic pelites and carbonates. At the moment, only one study considered the unconsolidated sediments in the SER highlands (fluvial terraces and alluvial plains) were carried out. Here, four unconsolidated sediment profiles associated to alluvial fan system dominated by gravity flows (D1), fluvial terraces (D2 and D4) and lacustrine environment (D3) in the SER lowlands were studied, using sedimentary facies, chemical weathering indexes, and Single-Aliquot Regenerative Optically Stimulated Luminescence technique (SAR OSL). The main chemical weathering reactions in the fresh rocks were silicate incongruent dissolution (muscovite and biotite) and partial hydrolyses of microcline and albite forming kaolinite and illite, with quartz being unweathered. The unconsolidated sediments have high maturity, being originated under intense weathering conditions, with warm and humid climate. OSL ages in the SER lowlands varying from 47.45 ± 3.68 ka to 1.92 ± 0.15 ka, revealing old ages in relation to samples dated in the SER highlands (from 26.35 ± 4.47 ka to 0.18 ± 0.04 ka). These sedimentary profiles were deposit under a mix of paleoclimatic context, prevailing dry climate between ∼50 and ∼29.5 ka and ∼7 and ∼3 ka, and wet conditions from ∼29.5 to 7 ka and <3.1 ka. Fluvial incision at D2 and D4 and the presence of lacustrine environment elevated 30 m above the current base level, as well as the presence of faults that displace blocks in sedimentary profiles, indicated the importance role of |tectonic in the study area. Thus, climate changes and tectonic events control the landscape evolution in SER.

A Bayesian age–depth model (ca. 9.0–1.0 ka) reveals contrasting ecosystem responses to the 8.2 ka and 4.2 ka climatic events and intensified human activity. Both events are marked by diatom-poor intervals and elevated chrysophyte/diatom ratios, indicating phases of hydro-ecological instability. Responses differed between the two intervals: the 8.2 ka event was followed by a more prolonged recovery, whereas the 4.2 ka event was followed by more rapid reorganization of the wetland system. A statistically significant regime shift at ca. 2.3 ka, identified using Sequential t-test Analysis of Regime Shifts (STARS), marks a transition from a climate-driven lacustrine system to an anthropogenically dominated agricultural landscape. This shift coincides with increased Oryza sativa phytoliths, adoption of iron farming tools, and regional demographic expansion. After ca. 2.3 ka, human activity surpassed climate as the dominant driver of wetland dynamics, illustrating the transition of small East Asian wetlands from climate-sensitive to human-dominated systems.

While previous research has examined the ancient Murghab alluvial fan on a broad scale, this study aims to disentangle local-scale forms of agricultural and water management responses to climate variability. As the region became increasingly arid during the 2nd millennium BCE, communities exhibited varied responses across different micro-ecozones. Modern ethnographic comparisons suggest that environmental changes can have different impacts on groups within the same landscape based on their strategies and social characteristics (e.g., small versus larger groups). This dynamic also seems to be mirrored in the human-water relationship and site distribution in the Murghab region during the Bronze Age. With a holistic approach that includes remote sensing reconstruction of the hydrological system, archaeological surveys, geoarchaeological investigation, and OSL analysis of the ancient fluvial system, we explore the responses of local communities during the landscape and social transformations of the 2nd millennium BCE. By focusing on two small-scale areas (Togolok and Ojakly), we discover that urban areas such as Togolok exhibited clustering around selected water channels, which facilitated good water management while increasing crop production and population wealth. In contrast, rural areas adopted decentralized, small-scale cultivation and an increased pastoralism to cope with aridity and hydrological instability. Ultimately, this study provides novel insights into the importance of small-scale investigations of local economic and social organizations. These findings contribute to disentangling broader narratives of economic and social resilience in the Murghab region during the Bronze Age.

The central basin of the South China Sea has historically lacked a high-resolution chronological framework for core samples and shallow strata, which significantly hampers research on sedimentary evolution history as well as paleoceanography and paleoclimate studies in this area. This study applied OSL dating and grain size analysis to analyze the upper 15 m core samples from the International Ocean Discovery Program (IODP) Site U1431A. Results show that sediments are mainly clay or clayey silt with an average grain size of no more than 30 μm. Since the Late Pleistocene, the maximum OSL age at the bottom is ∼100.1 ± 7.9 ka, and the minimum age at the top is ∼10.7 ± 0.7 ka. A high-resolution age model of Site U1431A has been constructed, confirming that the Toba volcanic eruption occurred ∼74 ka. Additionally, multiple turbidite events have been identified during the interglacial/interstadial periods, resulting in a rapid increase in sedimentation rates. It is hypothesized that these turbidite events are primarily driven by earthquakes and volcanic processes near the Manila Trench. The sedimentation rate in the central basin of the South China Sea shows a clear stadial-interstadial cycle with a relatively small relationship to sea level changes. During the glacial/stadial periods, the sedimentation rate can be as low as ∼2 cm/ka. In contrast, during the interglacial/interstadial periods, this rate may increase to ∼50 cm/ka. This significant variation is closely linked to fluctuations in the intensity of the East Asian monsoon.

Nawaz T2 - Geomorphology AB - This study reconstructs the late Quaternary glacial history of the Panchachuli (Neola) glacier, Darma Valley in the Central Himalayan region. Detailed geomorphic mapping and Optical Stimulated Luminescence (OSL) dating of the moraines and associated outwash terraces was carried out to determine the timing of glacial advances and subsequent retreat. Three major glacier advances were identified. The oldest, Panchachuli glacier advance (PGA)-1, is tentatively correlated with Marine Isotope stage (mid MIS 3). PGA-2, dated to ~19.82 ± 2.41 and 20.97 ± 2.36 ka, coincides with the global Last Glacial Maximum (gLGM; MIS 2). PGA-3, dated to ~5.16 ± 0.46 and 8.72 ± 1.02 ka, aligns with the early to mid-Holocene (mid-MIS 1). To constrain the deglaciation history, OSL dating was applied to fluvial terrace deposits, revealing distinct phases of glacier retreat. The oldest fluvial sediments date (~31.61 ± 3.61 ka) suggest deglaciation during the late MIS 3, a period marked by elevated solar insolation and enhanced monsoon activity. Subsequent deglaciation phases (~14–16 ka) correspond with the Bølling-Allerød warming, while the later phase (~2.6–2.9 ka) reflects glacier recession during the late Holocene glacier recession. The glaciation pattern in the Central Himalayas underscores the combined influence of temperature and precipitation on glacier behavior. These glacier changes align with regional Himalayan patterns, reflecting a coherent response to climatic fluctuations. While advances during mid-MIS 3 and gLGM suggest synchrony with North Atlantic climate events, the early Holocene advances—despite regional warming, mirror MIS 3 trends, highlighting the complex and non-linear interplay between temperature, moisture and glacier dynamics.

However, direct quantitative linkages between flood hydraulics and resultant landforms remain poorly constrained, particularly on the Tibetan Plateau. This study integrates sedimentological analysis, optically stimulated luminescence (OSL) dating, and two-dimensional hydrodynamic modeling (HEC-RAS) to reconstruct the chronology, hydraulics, and geomorphic impacts of Late Quaternary catastrophic outburst floods along the middle Yarlung Tsangpo River (YTR). Field investigations identified four diagnostic flood-related landforms (boulder bars, gravel dunes, gravel bars, and bedrock erosion surfaces) across 16 key sections. Our OSL dating, interpreted with careful consideration of partial bleaching and signal saturation, provides evidence for multiple, recurrent paleoflood episodes rather than a precise number of discrete events. For the well-preserved ∼11 ka Jiedexiu dammed lake outburst, HEC-RAS simulations revealed a peak discharge of ∼4.1 × 105 m3/s and bed shear stresses of 1–6 kPa, exceeding thresholds for mobilizing meter-scale boulders and driving bedrock erosion. The spatial pattern of erosion and deposition was tightly controlled by valley topography: narrow gorges focused flow energy (erosion-dominated), while broad valleys promoted energy dispersion and deposition. These multi-stage floods have played a key role in reinforcing the characteristic “pearl-string” valley morphology (alternating gorges and broad valleys) and in generating pulsed, high-magnitude sediment flux, highlighting their importance as drivers of landscape evolution in active orogens. This study provides a process-based framework for directly linking flood hydraulics to landform genesis in high-relief settings.

We show that weathering proxies are controlled by grain size, with little evidence for a long-term trend in chemical weathering in the last 3000 years. 87Sr/86Sr, but not εNd values are linked to grain size and the degree of chemical alteration, with coarser material generally lower in 87Sr/86Sr compared to fine sediment.

At Campiche, a former coastal lagoon in Chile's Metropolitan Region, multiproxy stratigraphic, sedimentological, and microfossil data reveal a laterally continuous tsunami sand sheet that extends ∼2 km inland, sharply disrupts lagoonal mud, and shows an erosional lower contact, rip-up clasts, and mud drapes from waning flow. Accompanying shifts from freshwater to brackish–marine diatom assemblages and the sudden appearance of salt-tolerant plant remains record a persistent increase in tidal influence, indicating coseismic subsidence. Radiocarbon and luminescence ages constrain its deposition to 1698–1782 CE, consistent with historical accounts of the 1730 tsunami and the absence of any other comparable event in the written record. Campiche thus complements previously reported uplift-dominated mid-Holocene records by showing that infrequent, subsidence-generating shallow ruptures—not just deeper, uplift-producing earthquakes—are an integral component of central Chile's megathrust behavior. Remarkably, this paleoseismic archive, formed during a brief window within a ∼4000-year marine-to-terrestrial transition and preserved in an emergent, semiarid, preservation-limited margin, suggests that similar evidence may exist in other unfavorable settings. Integration of the Campiche record with historical, geophysical, and geodetic data indicates that a shallow slip deficit of ∼20 m may have accumulated since 1730, consistent with highly coupled shallow asperities, the recent shift from coastal stability to gradual subsidence, and proposed 200–650 yr recurrence intervals for large tsunamis. Taken together, these lines of evidence suggest that Chile's Metropolitan Region now lies within a plausible near-term window for another large tsunamigenic rupture. These findings underscore the need to integrate paleoseismic records and deep–shallow rupture interplay—including infrequent shallow Mw ≥ 9 events superimposed on more frequent Mw ∼8 deeper earthquakes—into tsunami-hazard models for Chile and the wider Pacific.

T2 - Quaternary Science Reviews AB - The peak of the Last Interglacial (Marine Isotope Stage 5e; ∼128–117 ky) provides a valuable analogue for understanding sea level rise under future warming scenarios. Relative sea-level (RSL) indicators from passive margins are essential for constraining past sea levels and refining glacio-hydro-isostatic adjustment (GIA) models, thereby enhancing projections of future sea-level change and associated regional impacts. In this study, we present new luminescence ages from 17 sediment samples in outcrops along the Intracoastal Waterway near Myrtle Beach, South Carolina (USA). The sampling sites lie between a series of paleo beach ridges preserved as successive off-lapping deposits, the scarp toes of which have been previously identified as indicators of the maximum sea level during each associated sea-level highstand. Our results include ages corresponding with Marine Isotope Stages (MIS) 7 (∼200 ka), 5e (∼125 ka), 5c (∼105 ka), and the last deglacial period (∼14–12 ky). These new sea-level indicators, supplemented by the existing scarp elevation data, suggest that relative sea level in this region reached similar levels during MIS 5e and MIS 5c/5a. Comparison with GIA model outputs shows that more models fit our observations (from all time periods) when a peak GMSL of less than 5 m above present during MIS 5e is assumed, which makes those scenarios more likely.

This study presents a multi-proxy investigation of a three-step coastal terrace staircase on the Sinop Peninsula (southern Black Sea) to reconstruct the history of Black Sea highstands during the last glacial period. By integrating detailed geomorphological mapping, optically stimulated luminescence (OSL; n = 9), U-Th (n = 2), and radiocarbon (n = 1) dating with analyses of mollusc assemblages and strontium isotopes, we identify and chronologically constrain three major depositional phases related to highstands at 45–35 ka (T1; n = 4), 85–69 ka (T2; n = 6), and 105–95 ka (T3; n = 2). The base of T1 terrace contains marine fauna indicative of Mediterranean inflow and salinities of ∼28-35‰. In contrast, the top of T2 terrace hosts a unique assemblage of Caspian endemic molluscs, providing the first direct coastal faunal evidence for a Caspian incursion into the Black Sea at ∼69 ka. The age of the T3 terrace represents a highstand likely associated with Mediterranean connectivity during MIS 5c. Modeled uplift rates (0.6–0.8 mm yr−1) indicate that these highstands reached elevations close to the present sea level, diverging from global eustatic reconstructions for equivalent periods. Our results refine the late Pleistocene Black Sea sea-level curve and reveal that its evolution was marked by episodic, high-amplitude fluctuations driven by alternating connections with the Mediterranean and Caspian seas, likely modulated by meltwater routing from the retreating Eurasian Ice Sheet during interstadials.

Chronologies of coastal dunes in Guangdong province (China), which has a total of 4,300 km of coastline, are poorly established, hindering a comprehensive understanding of coastal dune processes in northeastern coastal SCS. In this study, we presented optically stimulated luminescence (OSL) dating results of 28 samples from seven profiles and two drilling cores, on five coastal dune fields in the Lufeng-Huilai area, eastern Guangdong. Six samples from two semi-cemented, weathered Old Red Sand dunes yielded saturated De values, showing minimum ages between 66 ± 4 ka and 364 ± 20 ka. Twenty-two OSL ages from the other three sand dunes were dated to Holocene. Our dating results, combined with 147 published OSL ages from the northeastern coastal SCS, reveal three major depositional stages: 1) The ∼12–5 ka stage linked to marine transgression and strengthened summer monsoon; 2) The ∼4–2.5 ka stage linked to expansion of nearby river deltas or relative sea level drop; 3) The post-1.5 ka stage linked to advancement of agricultural technologies and population growth in southern coastal China, either by natural growth or migration from the northern China to the southern coastal areas due to wars in the north. Between these major stages are two periods of reduced accumulation during ∼5–4 ka and ∼2.5–1.5 ka, with the former linked to cease of transgression or intensified seaward winter monsoon, and the latter linked to intensified farming activities in coastal dune areas.

However, additional palaeoenvironmental, palaeoclimatic and sea‐level records are needed to improve our understanding of coastal evolution and local environmental changes. This study investigates mangrove sediment from the Prasae Estuary Mangrove (PEM) complex in Rayong Province, eastern Thailand. The PEM complex is an estuarine fringing mangrove influenced by the mixed tidal‐fluvial dynamics of the Prasae River mouth. The region's low‐relief geomorphology includes intertidal mudflats, wetlands and relict sand deposits associated with relatively high sea levels during the Late Holocene. To reconstruct sea‐level changes, beach ridge deposits from the area were dated using optically stimulated luminescence. The results indicate a progressive seaward‐younging pattern of the beach ridges, implying shoreline progradation of at least 2 km over the past 1240±40 years in response to a gradual marine regression of less than 2 m during the Late Holocene. The formation of these beach ridges created favourable conditions for the mangrove forest to colonize the Thung Prong Thong area between 690 and 210 years ago. Geochemical analyses of mangrove sediments, including elemental composition (C, N) and δ 13 C values, indicate a predominance of terrestrial organic matter input, primarily from freshwater discharge and mangrove leaf litter. The accumulation of substantial amounts of organic carbon in the soil highlights the role of mangroves as important carbon sinks. Over the past 38 years, land‐use changes, particularly the conversion of mangrove areas into shrimp farms, have led to an estimated carbon release of approximately 14 800 Mg C (mega gram carbon = 1000 kg) to the atmosphere. However, conservation efforts have at the same time contributed to the expansion of mangroves and increased carbon sequestration along the PEM coast, resulting in a net increase in carbon stock accumulation of ~17 500 to ~22 800 Mg C. Given the substantial impact of land‐use changes on carbon stocks, this study underscores the importance of sustainable land management and long‐term monitoring of coastal mangrove ecosystems.

G. AU - Bhandari, Subhash T2 - Journal of Quaternary Science AB - ABSTRACT Dryland rivers are sensitive indicators of both long‐term and short‐term climatic fluctuations. These rivers are also useful archives for understanding tectonic responses superimposed on climatic fluctuations, which eventually provide important data for paleoclimatic and paleoseismic studies. In this context, we investigated fluvial sediments along the tributary‐paleochannels of the Khari River, which is a major dryland river of the Kachchh region in western India. This study reconstructs sedimentation patterns using lithofacies, architectural elements, facies associations, and Optically Stimulated Luminescence dates and indicates that the Khari River and its paleochannels have evolved in eight phases since MIS‐4, depicting both the climatic fluctuations and sedimentation response to tectonics. The adjoining Katrol Hill Fault, the Kachchh Mainland Fault, and their splays tectonically modulated the topography of the Khari basin. Two tectonically induced base‐level lowerings at ~74 ka and ~20 ka beveled the Mesozoic bedrocks underlying the alluvium and were followed by high‐magnitude‐low‐frequency ephemeral floods. Climatically induced aggradation phases occurred between approximately 67 ka and 59 ka, 48 ka and 37 ka, and 9 ka and 7 ka, showing a floodplain environment and sustained and wetter hydrological conditions. The lateral erosion of the underlying Mesozoic bedrock at ~50 ka and vertical incision at ~30 ka are marked as climatically governed phases. An uplift event (tectonic activity) is marked at ~7 ka, which led to debris‐flow deposition followed by vertical incision of the paleochannel and the Khari River. This study revealed that ephemeral floods, which are characteristic features of drylands, dominated fluvial sedimentation. The combination of enhanced precipitation and steepened topographic relief serves as two essential criteria for sedimentary discharge in these rivers.

Palaeomagnetism in conjunction with combined U‐series and electron spin resonance (ESR) dating of fossil teeth consistently constrain the age of Incarcal‐I to the latest part of the Early Pleistocene. Specifically, with palaeomagnetic results showing reverse magnetic polarities for the large majority of the samples and no indisputable evidence of normal polarity in the stratigraphic succession, the deposits may be reasonably correlated to the Matuyama Chron (2.61–0.77 Ma), thus providing a minimum age constraint of 0.77 Ma for the sedimentary infill. Additionally, direct dating of two fossil teeth of Hippopotamus antiquus using the most advanced analytical procedures, through a combination of unusually high sampling density ( n  = 17) for bulk ESR and U‐series analyses and high‐resolution laser ablation Inductively Coupled Plasma‐Mass Spectrometry (ICP‐MS) analyses, yields a mean age of 862 ± 52 ka (1σ). Interestingly, the data set collected shows the exceptionally high spatial homogeneity of the ESR and U‐series data across dental tissues and of the natural radioactivity of the sedimentary environment. Furthermore, the uncertainty around the uranium uptake modelling carries very little weight in the age calculation, which is unusual for such old fossil teeth. Consequently, this set of evidence supports the robustness and reliability of the ESR chronology, adding a new solid chronological tie point for biochronological inferences. In summary, the various lines of evidence available enable confident positioning of Incarcal‐I in the latest part of the Early Pleistocene, that is, somewhere between the end of the Jaramillo Subchron (1.01 Ma) and the Matuyama–Brunhes boundary (0.77 Ma). The numerical dating results indicate that the fossil assemblage of Incarcal‐I is coeval with those from other well‐constrained key Spanish localities such as Atapuerca Gran Dolina TD4‐6, and Vallparadís Station EVT7, highlighting the overall exceptional density of the Iberian fossil record between ~0.8 and ~1.0 Ma. Finally, a critical evaluation of the existing age constraints available for the Calabrian (1.80–0.77 Ma) fossil localities of the Iberian Peninsula is also proposed here, with a first tentative classification of the sites into four main categories (A to D) based on the robustness and precision of their chronostratigraphic framework.

Optically stimulated luminescence ages show that the rates of dune accumulation varied during the latest Pleistocene and Holocene. Sedimentary structures indicate that megadune migration was the result of strong northwesterly “Shamal” winds. During the same interval of the late Pleistocene and early Holocene, linear dunes in the northeastern United Arab Emirates were also accumulating rapidly, indicating that the period 16–9 ka was characterized by regionally widespread dune formation and/or reworking. The dune has subsequently migrated to the SSE almost 900 m since the early Holocene, at an average rate of 77 m/k.y., indicating persistence of the Shamal wind system for at least 20 k.y. Rates of megadune migration and wet sabkha accumulation reveal that, despite their very large size, less than 1% of the megadune would be preserved in a sedimentary record.

Here we review the closing discussion of this meeting and discuss subjects of current debate: issues related to aliquot size in luminescence dating; statistical models for age calculation when working on well-bleached samples; the importance and limitations of dose recovery tests; estimation of water content averaged over sediment history; age calculation methods and software, and the need for intercomparisons; and, finally, errors and uncertainties in luminescence dating. For each topic, we review the existing literature, summarise the state-of-the-art and provide recommendations based on our views and interpretation as our contribution to the debate. We suggest that: aliquot selection should be systematically questioned rather than routinely applied; the Central Age Model leads to sample dependent but systematic age underestimation; light recovery tests are preferred to dose recovery tests (although the two are equivalent at lower doses); there is considerable room for improvement in our methods for lifetime water content estimation; and a careful, thorough treatment of errors and uncertainties (especially in dose rate) is required for reliable chronological modelling of luminescence ages. The LED2023 meeting held in Copenhagen ended with a discussion of currently non-consensual issues in OSL dating. We list the discussed questions and review the six following items based on existing literature: issues related to aliquot size in luminescence dating; statistical models for age calculation when working on well-bleached samples; the importance and limitations of dose recovery tests; estimation of water content averaged over sediment history; age calculation methods and software, and the need for intercomparisons; and, finally, errors and uncertainties in luminescence dating.

Understanding these past climatic changes is crucial for predicting and adapting to future climate variability and its potential impacts on human societies. Geoarchaeological evidence indicates that the main cause of “metamorphosis” or “de-urbanization” of Indus Valley Civilization-one of the world’s early and most advanced civilizations were rapid climate change and declining of Indian Summer Monsoon. The Indus population relied heavily on the agricultural system and monsoonal flooding was its lifeline that was ruined due to the climatic ravaging. This research offers a comprehensive study into the relationship between climate change and the decline of the Indus Valley Civilization during the Holocene Epoch. Records reveal aridification at approx. ~16.3 ka, with a period of enhanced accumulation of dune sand, at around ~12.0 and ~10.2, ~7.5 and ~3.8 ka followed by intervening affluent monsoonal activity at ~15.4, ~13.2, ~6.4, ~4.6 and ~1.5 ka. This climatic fluctuation was also supported by stable oxygen isotope data from bone samples (δ 18 O) w which is enriched by (+3.26‰) in Rakhigarhi cultural mound-4 aged ~7.5 ± 0.4 ka (Late Hakra period) indicating weakening of monsoon. Lowest (δ 18 O) w value of −0.41‰ was found in Rakhigarhi cultural mound-6 yielding ~6.4 ± 0.4 ka (Early Harappan time), suggesting very intense monsoon activity with active fluvial regime which supports the onset of flourishing of Harappan civilization. The (δ 18 O) w enrichment (+2.72‰) in the Kalibangan bone sample (~3.8 ± 0.2 ka, Mature Harappan) indicates a weakened monsoon aligning with the 4.1 ka global event. Combined results reveal climatic shifts linked to major droughts (~8.2 and ~4.2 ka BP), validating the Meghalayan Stage onset (~4.2 ka). This severe arid phase likely transformed the fluvial landscapes of Rakhigarhi and Kalibangan, contributing to the Harappan civilization’s final collapse.

T2 - Quaternary Geochronology AB - The study of estuarine sedimentary archives provides valuable insights into their geomorphological evolution over the past two centuries, enhancing our understanding of estuarine responses to climate change. Establishing a reliable and precise geochronological framework is therefore essential for monitoring these changes. This study evaluates the performance of quartz Single-Aliquot Regenerative (SAR) OSL and AMS 14 C dating in four estuaries along the western coast of France. The results are compared with cartographic data, serving as an independent age control. Of the 14 OSL dated samples, 10 yield depositional ages consistent with cartographic data, whereas the remaining 4 appear to overestimate ages by 20 to 100 years. In contrast, AMS 14 C dating reveals numerous stratigraphic inversions, with at least 12 out of the 16 measured samples overestimating the depositional age in some cases by up to 5,000 years, in total disagreement with cartographic data. The discrepancy between the OSL and radiocarbon ages reflects the constant reworking of allochthonous material, to which is added the further uncertainty associated with the local reservoir age. These factors fundamentally limit the reliability of 14 C dating regardless of the material analysed. By contrast, the OSL signal displays remarkable resilience, with any age overestimation linked to partial bleaching remaining minor (on the order of decades) compared with the errors affecting 14 C ages. This underscores the capacity of OSL dating to resolve short-term environmental changes and positions it as the most reliable tool for constructing high-resolution chronologies of the last centuries in macrotidal estuarine settings.

These artifacts are a common component of coastal plain archaeology in Texas and elsewhere in the state. Many such sites, especially those situated in sandy soils, do not preserve charcoal well, which renders dating the occupations challenging. The clayey matrix of the Lodoso Site does preserve charcoal, which presents an opportunity to assess the suitability of luminescence dating of burned clay objects by thermoluminescence (TL) and optically stimulated luminescence (OSL), and directly compare those results with charcoal collected from the same excavation provenience, as well as OSL dating of the sedimentary matrix. The TL and OSL results generally track together well but are consistently slightly older than charcoal collected from the same level. The charcoal dates suggest the midden formed between approximately 1500 and 2300 years ago, whereas the luminescence ages suggest formation occurred between 2000 and 3000 years ago. Where the luminescence ages occur out of stratigraphic order, so do the paired charcoal samples, indicating that this is a result of pedoturbation. The results of both radiocarbon and luminescence dating indicate that the midden is a diachronic feature resulting from use over a prolonged period rather than the product of a single burning event.

This study presents new depositional ages for alluvial deposits near the mouth of the Mission Creek drainage to investigate potential Holocene activity of the MCF. We estimate a mean depositional age of 0.7 ± 0.2 ka for the alluvium deposited in the drainage valley, contradicting previously inferred ages of >3–18 ka. The young ages for alluvium, often indistinguishable from the age of modern alluvium, suggest that grains are transported during high-energy flash flood–like events. A comparison of luminescence and cosmogenic 10 Be ages from alluvial surfaces adjacent to the Mission Creek suggests a possible reworking event at ∼30 ka. Young alluvium ages, together with evidence for frequent flash floods, suggest that this site is rapidly resurfacing and therefore unlikely to preserve surficial rupture signatures older than a few hundred years. Therefore, the lack of observable offsets in deposits overlying the MCF does not imply Holocene inactivity.

This study reconstructs the environmental evolution of the Velyka Andrusivka sequence using a multiproxy approach integrating sedimentological, geochemical, mineralogical, magnetic, and palynological data supported by luminescence dating. The succession rests on Dnieper glacial till and comprises loess units from the last and penultimate glacial cycles, palaeosols, and an upper chernozem formed after loess deposition had ceased. Optically stimulated luminescence ages range from ∼22 to 187 ka, revealing hiatuses and diachronous boundaries relative to Marine Isotope Stage divisions. The older loess is more heterogeneous and enriched in Zr-Hf-REE with mixed provenance, whereas the younger loess is more homogeneous and dominated by distal dust. These contrasts demonstrate how local sediment recycling and regional dust supply jointly shaped the environmental signal. Palaeosols record phases of weathering, while the upper chernozem largely retains the parent-loess texture within a sequence overprinted by postdepositional alterations in colour, geochemistry, and magnetic properties. Comparison along the 50°N transect shows that robust interpretation of the sequence requires integration with neighbouring loess–palaeosol records, as only multi-site correlation captures shared stratigraphic patterns and site-specific deviations, enabling reconstruction of environmental processes across multiple spatial scales.

The stratigraphic profile records 13 aeolian-soil cycles, characterized by alternating phases of aeolian deposition, soil formation, and wildfire episodes, reflecting the interplay between short-term climatic oscillations and aeolian processes. Radiocarbon dates were obtained from 26 charcoal samples embedded within palaeosols and charcoal horizons and calibrated using the IntCal20 curve, while OSL dating of quartz grains provided additional chronological control for aeolian sediments. The integration of these two dating methods established a robust timeline of environmental changes. The aeolian activity began during the Oldest Dryas and intensified during the Allerød interstadial, with four distinct wildfire events associated with rapid vegetation recovery and fire-prone landscapes. The Younger Dryas was marked by widespread aeolian deposition under arid climatic conditions, with no organic layers preserved. In the Holocene, nine independent wildfire episodes spanning approximately 4500 years were identified, linked to warm climatic conditions and the dominance of pine forests. Aeolian activity persisted into the Middle Holocene, accumulating nearly three meters of sediment before stabilizing around 7 ka BP due to increased vegetation cover. This study underscores the effectiveness of integrating radiocarbon and luminescence dating to resolve Late Quaternary chronologies, providing insights into fire-vegetation dynamics and aeolian processes within the European Sand Belt.

However, detailed evidence regarding the timing and processes of its Quaternary glaciations remains limited in many subregions. Here, we systematically identify, quantify, and date glacial landforms in the Chaka North Mountains using an integrated approach that combines high-resolution remote sensing, digital elevation model (DEM) morphometric analysis, and optically stimulated luminescence (OSL) dating, supplemented by field mapping. Our morphometric results demonstrate that cirques, U-shaped valleys, and distinctive moraine ridges are widely distributed throughout the region, providing evidence of significant Quaternary glacial activity. OSL dating of sediments mantling frontal moraines provides minimum stabilization ages of 111.5 ± 9.3 ka and 110.7 ± 11.2 ka, indicating a major glaciation during the penultimate glacial period (Marine Isotope Stage 6, MIS 6). Additional OSL ages of 112.7 ± 23.6 ka and 74.9 ± 11.5 ka from glacial lacustrine sediments indicate two distinct phases of lacustrine sedimentation: one during MIS 6 and the other during late MIS 5a. These findings suggest that the Chaka North Mountains experienced more extensive glaciation during MIS 6 than during the Last Glacial Maximum (LGM), as reflected by a significantly lower equilibrium line altitude (ELA). Our study provides a foundational chronostratigraphic framework for a key transitional region, offering critical constraints on the spatiotemporal evolution of the Quaternary cryosphere and the drivers of glacial asynchrony in the NQTP. • First OSL chronology for the Chaka North Mountains constrains a major glaciation to MIS 6. • Paleo-ELA reconstruction (∼3174 m) indicates peak glaciation occurred in MIS 6, not the LGM. • Morphometric analysis and sedimentology resolve the tectonic vs. glacial origin of U-shaped valleys.

T2 - Quaternary Science Reviews AB - Floods are among the costliest natural disasters, causing extensive damage and fatalities worldwide. Mountainous regions of the Mediterranean Alps are highly vulnerable to extreme hydrological events, whose frequency is increasing in the context of climate change favouring convective storms. In October 2020, the Roya valley was struck by an extreme hydrological event. The amount of rainfall (return period >1000yr) and discharge (>100yr), triggered major geomorphological changes, including subsantial channel widening, slope destabilisation and extensive bank erosion. This study provides unprecedented sedimentological data on torrential dynamics in the Roya Valley, based on 14C and OSL dating of newly exposed flooding deposits following Storm Alex. Five clusters of preserved fluvial and torrential deposits ranging from the Younger Dryas–Holocene transition to the Little Ice Age are identified. These preservation clusters correspond to periods of wetter condition and anthropogenic influence. By combining sedimentological analyses with documented pollen and sediments records from lakes in the Mercantour massif, as well as historical archives, this study presents one of the first flood-frequency reconstructions for a Mediterranean Alpine catchment over a multi-millennial timescale. Past flooding events (on centennial to millennial scales) leave distinctive sedimentary signatures, characterised by thick deposits and the mobilisation of coarse particles, before being reworked within the broader autogenic dynamics of the river system. Reconstructing the frequency and occurrence of past extreme flood events provides key insights into the conditions under which such events occurr, and offers valuable information for the development of flood-risk scenarios, particularly in mountainous areas that are among the most affected by contemporary climate change.

N. AU - Bolikhovskaya, N. S. T2 - Stratigraphy and Geological Correlation AB - The Late Pleistocene of Northern Eurasia remains a subject of active scientific debate, particularly in the context of climate change. This study presents a palaeoenvironmental analysis for the interval of Marine Isotope Stage (MIS) 5 (approximately 130 to 70 ka), including the first warming phase of interglacial rank. Special attention is given to a detailed study of the Voka key section on the south-eastern coast of the Gulf of Finland. This section is remarkable for the completeness of its geological and palaeontological record, which allows a deeper understanding of the Late Pleistocene palaeogeographic history, especially during the latter half of MIS 5. Climatic and stratigraphic analysis was carried out using the palynological method, while the chronological framework of palaeoclimatic events was established by infrared optically stimulated luminescence (IR-OSL) dating. This allowed the dynamics of the first Late Pleistocene warming of interglacial rank to be traced, correlating with the Mikulino interglacial in the Eastern European Plain. Comparison of the results with electron spin resonance (ESR) dating of mollusc shells from palaeoshelf deposits in climatically highly sensitive regions of Eurasian North confirmed the synchronicity of major palaeogeographic events in both terrestrial and marine ecosystems during MIS 5. Our interdisciplinary research provides new data that contribute to reconstructions of Late Pleistocene palaeogeographic events and refine our understanding of climate dynamics during MIS 5.

We compile luminescence ages and climatic proxies from 107 loess sections to reconstruct dust mass accumulation rates (MARs) and hydroclimate variability over the past 130 thousand years (ka). The results reveal a consistent pattern: high MARs and low moisture during Marine Isotope Stages (MIS) 4 to 2 (71 to 12 ka) and low MARs with high moisture during MIS 5 (130 to 71 ka) and MIS 1 (12 ka to present). These shifts are driven by cooling-induced changes in atmospheric humidity linked to fluctuations in ice volume across glacial-interglacial cycles. Within MIS 5, MIS 4 to 2, and MIS 1, pronounced spatial and temporal contrasts in MARs and moisture emerge between westerlies-dominated northern Iran and central Asia and monsoon-dominated East Asia. Notably, westerly and monsoonal precipitation vary out of phase, driven by insolation-controlled shifts in moisture transport.

These impurities dominate the characteristic deep-red luminescence of feldspar, while the host lattice itself also exhibits intrinsic luminescence associated with self-trapped excitons (STEs). Despite the central role of feldspar in luminescence dosimetry and geochronology, the microscopic mechanisms underlying both intrinsic and Fe 3 + -related luminescence remain incompletely understood. Here, we present a comprehensive first-principles investigation of disorder, intrinsic defects, and impurity-related charge trapping in K-feldspar. Using a cluster expansion trained on density functional theory calculations, we determine the ground-state Al–Si ordering and quantify the formation of Al–O–Al linkages at high temperatures. Based on this structure, we identify energetically favorable intrinsic defects and demonstrate that hole polarons localize preferentially on oxygen atoms bridging AlO 4 and SiO 4 tetrahedra, while Si–O–Si bridges do not stabilize holes. Rare Al–O–Al bridges formed at melting temperatures are shown to be particularly efficient hole traps. We compute STE configurations and vertical emission energies using a hybrid functional approach, obtaining emission energies in excellent agreement with experimental measurements. Furthermore, we show that Fe 3 + impurities strongly modify local charge trapping: Fe 3 + preferentially captures electrons to form Fe 2 + , while also stabilizing hole polarons on neighboring oxygen sites, forming metal-oxyl complexes. Based on these results, we propose a microscopic mechanism for Fe 3 + -related luminescence in which electron capture by Fe 3 + is followed by spin-selective recombination that populates the Fe 3 + excited state T 1 4 . Our results provide a unified atomistic picture of intrinsic and impurity-driven luminescence in feldspar and establish a quantitative foundation for modeling charge trapping and recombination processes relevant to luminescence dating.

T2 - Paleoceanography and Paleoclimatology AB - Abstract Understanding why proximal loess in southern South America (SSA) exhibits a contrasting evolution of dust deposition flux since the Last Glacial Maximum (LGM) compared to that of distal Southern Hemisphere (SH) archives remains a major unresolved problem. To shed light on this issue, this study examines dust emission, transport, and deposition in SSA over the past 43,000 years through multiproxy analysis of a Pampean loess section. We reconstruct dust mass accumulation rates (DMAR) and their controls through quartz and feldspar luminescence dating, sediment properties, and paleoclimate simulations. Increased DMAR was observed during Marine Isotope Stage 3 due to greater sediment availability and humid conditions. A sharp decline during the LGM was linked to wetter source areas and arid Pampean conditions that reduced wet dust deposition efficiency, while intensified Southern Westerly Winds strengthened dust emissions from proximal sources, as well as dry coarse dust deposition at the study site. During deglaciation, dust deposition in the Pampean region occurred under windier but relatively wetter conditions, resulting in dry sedimentation dominated by coarser fractions from nearby sources. In the Holocene, DMAR reflects the combined effects of enhanced dust emission under arid conditions in source regions and increasing precipitation after ∼3.9 ka in the Pampean plains. Our results provide constraints on accumulation modes and sediment provenance, showing how hydroclimate variability and sediment availability shaped SSA dust dynamics. Together, they reconcile contrasting dust flux trends between proximal Pampean loess and distal SH archives through coupled changes in source activity, depositional processes, and atmospheric circulation.

In this study, we address the issue of count rate linearity of photomultiplier modules commonly employed in luminescence readers. Considering instrumental thresholds and typical signal outputs, in most scenarios, this deviation is not a concern. However, in corner cases where detectors are operated in regions where non-linearity of count rates becomes significant, corrections are necessary. This is a well-known issue, but to the best of our knowledge, not all measurement systems utilise a correction. In this note, we provide some technical background and show that the impact on the equivalent dose can reach easily 2 % even in conservative scenarios. We then demonstrate how this can be post-corrected using a straightforward dead-time non-linearity correction implemented in the R package ‘Luminescence’.

However, its application has long been limited by the difficulty of establishing a reliable chronology. In this study, we used 230Th dating, accelerator mass spectrometry radiocarbon (AMS14C) dating, and single-grain quartz optically stimulated luminescence (OSL) dating methods on the CSS collected from a karst cave in Southwest China (SW-C), aiming to assess the applicability of OSL dating in such sediments. The OSL and AMS-14C dating results are consistent within analytical uncertainties, indicating that the OSL method can establish a reliable chronology for CSS. Through integrated analyses of sedimentation rate, grain size, and geochemical elements, we found that CSS can serve as a valuable archive for paleoenvironmental reconstruction. Finally, by combining archaeological evidence with other data, we reveal the impact of hydroclimatic changes and human activities on the regional environment since the late Holocene. From 4000 to 1500 yr BP, climate change played a dominant role, with wetter periods fostering agricultural expansion and cultural prosperity. Since 1500 yr BP, human activities have become one of the primary drivers of environmental transformations. Regional hydroclimatic variability has been jointly controlled by both external and internal forcing factors, including Total Solar Irradiance (TSI), meridional migration of the Intertropical Convergence Zone (ITCZ), and fluctuations in the El Niño-Southern Oscillation (ENSO).

Therefore, this study investigated and modelled the chronological and quantitative shifts in heavy metals and bulk organic parameters in Dal Lake core sediments for last ~3700 years using optically stimulated luminescence (OSL) dating, inductively coupled plasma mass spectrophotometry (ICP-MS), elemental and time series forecasting analysis. Due to the limited scientific literature available on the temporal trends and forecasting of heavy metals and nutrients in the bottom sediments of the lake, incorporating such a multi-dimensional approach facilitates accurate historical reconstruction, detailed elemental characterization, and predictive insights into future contamination, providing a thorough understanding of sediment composition and environmental changes over time. The findings of study revealed substantial variations in heavy metals and organic parameters within the lake from ~12.5 to ~3719 years before present (BP). Sediment pollution indices showed anthropogenic pressures on lake between ~567 to ~12.5 years BP, indicating moderate to strong pollution in upper sediment layers. Potential ecological risk index highlighted moderate risks up to ~216 years BP and low risks from ~285 to ~3719 years BP. Organic parameters, such as total organic carbon, nitrogen, phosphorus, and C/N ratios indicated rising eutrophication from ~476 to ~12.5 years BP. Multivariate statistical analysis highlighted a strong positive relationship between heavy metals and organic parameters, depicting common environmental pathways and sources of contamination in Dal lake. Time series analysis using auto-regressive moving average model confirmed continuous anthropogenic alterations on lake and predicted increasing pollution trends in the coming decades. The model forecasted zinc concentration in Dal Lake over next 35 years to increase by ~15 times, iron (~35), manganese (~24), lead (~76), arsenic (~239), mercury (~100), cadmium (~16), chromium (~5), molybdenum (~27), copper (~10), cobalt and nickel (~14) times from current observed concentrations. Similarly, total organic carbon in Dal Lake top sediment layers is expected to increase by ~20 times, total nitrogen ~37 and total phosphorous ~36 times, indicating potential hyper-eutrophic conditions in coming decades. Novel insights provided by present study could have significant policy implications beyond regional context offering a framework for understanding the long-term anthropogenic fingerprints in Himalayan and global lake ecosystems. • Increasing heavy metal trends in topmost sediment layers (~73 years BP) of lake. • Upper sediment layers revealed potential ecological risk to Pb, Cu, Hg and As. • Nutrient level trends indicated changes in lake ecosystem from ~476 years BP. • ARIMA model predicted increased pollution trends in Dal Lake in coming decades. • Time series forecasting data could have significant policy implications on Dal Lake.

T2 - Palaeogeography, Palaeoclimatology, Palaeoecology AB - The Late Pleistocene-Holocene marks a sharp transition in climate perturbation affecting landform patterns and depositional sequence in tectonically active regions. We investigate the fluvial landforms and Holocene fluvial-lacustrine sedimentary sequences in an ephemeral landslide-dammed intra-montane paleolake, which acts as an archive for reconstructing extreme events driven surface processes and paleo-climatic history along the Daili-Imphal River in the Indo-Burmese Range. The effect of climate-tectonic coupling on surface processes is explored through quantitative geomorphologic analysis of the landscape and sedimentological proxies, including grain size and shape analysis, geochemistry, and optically stimulated luminescence (OSL) dating of the lacustrine sequence. This analysis helps constrain the climatically sensitive hydrodynamics during the Late Pleistocene-Holocene period. The lack of grain size, geochemical variations in the sediment column, and geochemical affinity with the substrate, the Disang Shale Formation, point towards the dominance of erosion from a proximal sediment source. We argue that the pre-Holocene Bølling-Allerød (12–12.9 ka) climatic extreme caused excessive mass wasting, which blocked the Daili-Imphal River and formed a paleolake, paradoxically resulting in a low sedimentation rate during the early Holocene. The sedimentation rate increased during the Mid-Late Holocene due to local climatic optima. This unique setup highlights the role of local climatic fluctuations on the ephemeral growth of geomorphic and sedimentary archives.

Through integrated methodologies including field investigations, high-precision remote sensing image interpretation, UAVs Photogrammetry, high-density electrical profiling, and OSL Dating, this study reveals the following key findings: The Yadu Fault exhibits a northwest-striking with a dextral strike-slip motion, which cumulative displacements of 31.7–74.1 m observed across multiple gullies. The fault truncates Late Pleistocene strata dated at 34.0 ± 5.0 ka, confirming its activity during the Late Quaternary. The horizontal slip rate is estimated about 1.3 mm/a, classifying the Yadu Fault as a Late Pleistocene active structure. These results provide essential constraints for seismic hazard assessments and tectonic evolution studies in the region.

AU - May, Jan‐Hendrik AU - Lauer, Felix T2 - New Zealand Journal of Geology and Geophysics AB - We compared temporal variability in dust and loess accretion in New Zealand's South Island with glacial activity in the central Southern Alps, considered the main mechanism of silt production, in (i) a proximal loess deposit at Barrhill, Rakaia River and (ii) a distal dust record from a peat mire in Central Otago. We applied novel luminescence dating approaches at Barrhill, targeting both polymineral silt and K‐feldspar sand. Results demonstrated loess accretion began from ~8.5 ± 1.7 ka, with accumulation rates increasing by 7 times after ~2 ka, before decreasing toward the present. In the peat record, trace‐element geochemistry was used to distinguish New Zealand‐sourced dust from Australian dust. Like Barrhill, deposition of New Zealand‐sourced dust increased by ~4 times from ~3 ka, while also recording high deposition during the Little Ice Age. Changing dustiness in both records is attributed to climate‐modulated sediment production. At Barrhill, this was linked directly to glacial advances in the Rakaia catchment, while in the more distal peat mire it likely resulted from enhanced periglacial activity. Together, both records demonstrate that dustiness closely tracks glacial variability in the South Island, highlighting potential for further detailed studies of dust production and glacial dynamics from New Zealand's loess.

AU - Wood, D. AU - Frouin, M. AU - Plackett, R. AU - Osborne, C. AU - Hill, M.A. AU - Schwenninger, J-L. T2 - Journal of Instrumentation AB - Abstract The natural sedimentary environment possesses a mixed field of α-, β-, and γ-radiation emitted from the radioactive decay of radionuclides such as potassium-40 (K-40), uranium-238 (U-238), and thorium-232 (Th-232). These emissions are responsible for dose accumulation in feldspar and quartz mineral grains, forming the basis of luminescence dating. The inhomogeneous spatial distribution of radionuclides in sediments and local energy deposition at the grain level can cause microdosimetric variations, contributing to overdispersion in equivalent dose (D_e) distributions. Understanding and resolving these variations requires a detector that can simultaneously map various types of radiation and their energy deposition at the micron scale. Here we present a workflow for configuring and applying Timepix3 (silicon-based hybrid pixel detector, 14 × 14 mm^2 active area, 256 × 256 pixels, 300 μm thickness) for high-sensitivity imaging of α- and β-particles simultaneously in mixed-radiation fields. The workflow includes particle-track reconstruction, charged-particle identification, background suppression, and energy calibration with a mixed α-particle source (Pu-239, Am-241, Cm-244; 5.15–5.80 MeV) in air. A linear energy calibration response was obtained; however, the detector was unable to fully resolve three α-particle peaks. While this appears to be a limitation, it ultimately provides insights into the detector's response under conditions that closely mimic the energy spectra of natural radiation, broad energy distributions, and measurement conditions such as ambient atmospheric pressure.

In this work, we present new slip rate determinations at three key sites (Tekoujiagu, Yeer, Damulo) along its middle-southern segments using UAV-based high-resolution topography and OSL dating. Results yield late Quaternary slip rates of 4.5 ± 1.4, 3.7 ± 1.1, and 5.5 ± 1.0 mm/a, respectively. Combined with previous data, the slip rate is 1.5–3.1 mm/a in the northern segment, 1.36–4.3 mm/a in the middle and 2.5–4.5 mm/a in the southern segment, which exhibits a spatial pattern of “higher in the south, lower in the north, with transition in the middle”. Temporal evolution suggests increased slip rates from the Late Pleistocene to Holocene. These characteristics indicate that the DLSFZ is a heterogeneous deformation system, where strain focusing on the southern segment reflects the block’s eastward escape constrained by the rigid Sichuan Basin (SB). Thus, the DLSFZ, especially its southern segment, serves as a key structure regulating crustal extrusion at the southeastern margin of the Tibetan Plateau (TP).

We apply rock surface luminescence dating to a bedrock scarp on the Huashan fault in central China, using OSL‐depth profiles (DPs) from multiple heights. Results reveal two coseismic displacements of 6.8 and >1.0 m. The two phases of exposure ages inferred from OSL‐DPs of the bedrock fault surface above ground (0.4 ± 0.3 and 1.1 ± 0.4 ka) are consistent with burial ages of slices from the fault surface covered by the colluvial wedge. These ages also correlate with historical earthquakes, including the 1556 Huaxian M ∼ 8.5 event with slip of 6.8 m, confirming rupture of the western Huashan fault. A magnitude of M8.3 inferred from multiple fault rupture lengths agrees with seismic intensity estimates. The fitted OSL‐DPs of bedrock samples buried or being buried by the colluvial wedge, together with the burial ages of slices, reveal the exposure and burial history of the wedge.

Optically Stimulated Luminescence (OSL) sensitivity of quartz grains offers potential as a sediment tracer, but its response to fluvial transport modes remains poorly constrained. Here we analyze 26 modern fluvial sediments along the Upper Yellow River (615 km from Zhaling Lake to Ruoergai Basin), comparing OSL characteristics across three transport regimes. The study reveals distinct patterns between fine and coarse fractions: Suspension-transported fine silt (4–11 μm) exhibits low OSL sensitivity (34.0 ± 12.0 to 551.3 ± 272.0 counts⋅mg 1⋅Gy 1, avg. 221.3 ± 125.0 counts⋅mg 1⋅Gy 1) and high residual doses ( 2.2 ± 2.1 Gy to 19.0 ± 3.8 Gy, avg. 8.2 ± 4.9 Gy). This results from: (1) persistent turbidity shielding particles from sunlight exposure; (2) colloidal aggregation significantly reducing effective surface area for bleaching; and (3) Organic acid etching from riparian vegetation degrading luminescence centers. Bedload-transported mediumcoarse grains (63–250 μm) show significantly higher sensitivity (63–90 μm: 137.9 ± 272.0 to 1939.0 ± 198.0 counts⋅mg 1⋅Gy 1, avg. 775.8 ± 138.7 counts⋅mg 1⋅Gy 1; 90–250 μm: 120.0 ± 52.0 to 1115.7 ± 20.0 counts⋅mg 1⋅Gy 1, avg. 513.2 ± 139.0 counts⋅mg 1⋅Gy 1) and near-zero residual doses (63–90 μm: -–0.5 ± 0.1 to 7.3 ± 0.9 Gy, avg. 0.7 ± 0.7 Gy; 90–250 μm: 0.7 ± 0.1 to 7.39 ± 0.9 Gy, avg. 0.5 ± 0.7 Gy), benefiting from repeated sunlight exposure during saltation/rolling and mechanical abrasion regenerating luminescence centers. Downstream trends show 24–27 % sensitivity increase within 300 km (e.g., 63–90 μm: 422.7 ± 13.2 to 1314.3 ± 26.1 counts⋅mg 1⋅Gy 1), demonstrating progressive signal enhancement. Notable deviations occur at: (1) Dari County (334 km), where road construction introduces low-sensitivity debris (DML: 527.0 ± 111.0 counts⋅mg 1⋅Gy 1), and (2) Maqu (744 km), where aeolian inputs elevate sensitivity (817.0 ± 51.0 counts⋅mg 1⋅Gy 1). The Ruoergai Basin shows 19–24 % sensitivity reduction due to tectonic subsidence limiting sediment reworking. These findings establish OSL sensitivity as an effective discriminator of transport mechanisms, with bedload grains (>63 μm) optimal for depositional dating and fine grains preserving source signals. The study provides a quantitative framework for sediment routing analysis in large fluvial systems.

AU - Jin, Lixin AU - Rittenour, Tammy AU - Reynard, Linda M. AU - Finstad, Kari AU - Murillo, Carmel G. AU - Sajid, Zulqarnain AU - Phillips, William T2 - Geological Society of America Bulletin AB - Loess-paleosol sequences in eolian deposits on the Snake River Plain, Idaho, western United States, preserve records of late Pleistocene to Holocene glacial-interglacial cycles. Here, we examine climate-driven changes in the timing and rate of loess accretion, soil formation, and pedogenic carbonate accumulation in the eastern and central Snake River Plain. High rates of loess deposition often correspond with dry, cold, and windy conditions and/or high sediment supply, while soil formation indicates landscape stability. Optically stimulated luminescence dating of four loess-soil sequences provides a record of the timing of loess deposition, and radiocarbon dating (14C) of soil inorganic carbon provides ages for soil formation and pedogenic carbonate precipitation. On the central Snake River Plain, marine isotope stage (MIS) 3 is marked by loess deposition between ca. 50 ka and 33 ka, and pedogenic carbonate accumulation between ca. 42 ka calibrated years before present (cal. B.P.) and 31 ka cal. B.P. During MIS 2, loess deposition between ca. 21 ka and 15 ka is contemporaneous with pedogenic carbonate precipitation. MIS 2 is characterized by diffuse pedogenic carbonate formation and rapid loess accumulation. Both the eastern and central Snake River Plain study sites experienced high rates of loess deposition during MIS 2; however, the eastern Snake River Plain had almost three times faster rates of loess accumulation (0.56−0.63 m/k.y. from ca. 25 ka to 17 ka) as compared to the central Snake River Plain (0.18−0.26 m/k.y. from ca. 21 ka to 15 ka). During MIS 1, loess deposition on the central Snake River Plain ca. 11 ka was coincident with pedogenic carbonate formation ca. 10 ka cal. B.P. MIS 3 and MIS 1 are characterized by A horizons and well-developed Bk horizons, indicating soil stability and lower rates of loess accumulation during these intervals. This study highlights the role of late Quaternary−scale climatic variability on rates and amounts of soil inorganic carbon storage.

These applications assume that luminescence signals from sample aliquots are reproducible, yet no study has explicitly examined preparation strategies that optimize inter-aliquot consistency. Consequently, no standardized methods for sample preparation exist in portable OSL research. This study initiates this discussion by testing how aliquot preparation and sample size influence reproducibility. Four samples were collected from postglacial eolian dunes in Alberta, Canada. For each sample, 20 aliquots were prepared using four approaches, yielding 320 aliquots: (a) monogranular layers of equal volume portions (~1.5 g), (b) monogranular layers of equal-weight (1.5 g), (c) monogranular layers mounted on double-sided adhesive segments of equal area (~1.0 g), and (d) multilayer portions of equal weight (12.0 g). All aliquots were analyzed with a portable OSL reader. Statistical results showed that for blue-OSL signals, reproducibility varied both among samples and across preparation methods. However, multilayer aliquots prepared with equal weights (12 g) consistently produced the highest reproducibility, suggesting that larger grain populations enhance inter-aliquot consistency. For IRSL signals, no preparation method offered a clear advantage.

AU - Wriston, Teresa AU - Jenkins, Geraint T. H. AU - Huot, Sebastien T2 - Geochronology AB - Abstract. This study examines the feasibility of dating pluvial lake beach ridges using rock surface luminescence dating techniques. Dating pluvial lake highstands in the internally drained Great Basin of the United States helps us understand the timing of changes in precipitation and temperature patterns in western North America during the Late Pleistocene. The majority of highstand ages have relied on few radiocarbon ages of shell and/or charcoal sometimes coupled with luminescence dating of sand. Within our study area in the south-central Great Basin, luminescence ages of sand-size particles have successfully dated aeolian influxes of sand during arid intervals, but have not successfully dated the highstand beach ridges, the best preserved of which are largely gravel. Directly dating when these gravel clasts were last exposed to sunlight via luminescence is ideal but their limestone and volcanic lithologies prove challenging. Initial measurements from these lithologies show that feldspar luminescence signals are suited to single-aliquot regenerative (SAR) dose measurement protocols and show evidence for heterogeneous bleaching of rock surfaces. Polymineral extracts from dissolved limestone clast surfaces from Coal Valley that contain sufficient detrital sediment exhibit infrared signals measured at 50 °C (IR50) with low to moderate fading rates. Single-grain ages from detrital sediment from three clasts, calculated using the central dose model, are statistically consistent with the radiocarbon age estimate of the Pluvial Lake Coal highstand. Crushed slices from volcanic clasts from Cave Valley could be dated using a high-temperature (290 °C) post-infrared infrared stimulated luminescence (pIRIR) signal with a correction for fading. Many ages obtained from volcanic clast surfaces are observed to be several thousand years younger than the expected age of the ∼ 18–20 ka beach ridge. This suggests that the volcanic rocks have been exposed to light long after the pluvial lake highstand, likely because of bioturbation, and that their most recent burial occurred in response to climatically driven soil formation processes. Comparisons between age-depth profile plateau ages from inside volcanic rocks and independent age control suggest that gravel-sized volcanic rocks were small enough to have been bleached throughout their entire thickness in the pluvial lake beach environment and that pIRIR signals that record the time of beach ridge formation and subsequent soil formation during the Pleistocene-Holocene transition may be preserved within the rock sub-surface. This study develops novel dating approaches for challenging rock lithologies. Rock surface dating techniques for pluvial lake beach ridges in the Great Basin should be further developed with consideration of local bedrock type(s), clast size, sample collection and preparation methods, gravel bleaching processes in pluvial lake environments and the impact of soil development and bioturbation on study sites.

Linear anomalies of vegetation vitality observed in satellite images motivated in-depth investigations of historical anthropogenic modification and exploitation of the paleo-floodplain of the late-glacial Bergstraßenneckar (BSN) in the Upper Rhine Graben near Mannheim (southwestern Germany). Stratigraphic investigations based on up to 1.7 m deep pits, sediment sampling, and laboratory analyses (grain size distribution; C, N, S; loss on ignition; X-ray fluorescence; morphoscopy of sand grains), as well as electrical resistivity tomography, reveal the presence of long parallel trenches cutting into the organic-rich and fine-grained natural strata which result from silting-up of the abandoned BSN channel during the Holocene. The linear features are interpreted as anthropogenic trenches and were later filled with sand. We identify an aeolian origin of the sand, which points to the use of sand, e.g., from the nearby Bettenberg dune of Last Glacial Maximum (LGM) to late-glacial age. The samples for optically stimulated luminescence dating (OSL) from the fill of the trenches show a wide range of equivalent doses and insufficient bleaching as sand was filled in lumps during shoveling. This results in ages ranging from the LGM to 300 years, depending on the aliquot and age model. This wide range indicates incomplete bleaching and is in agreement with the manual filling process in historical times. Further corroboration is provided by data from the Hesse State Archive at Darmstadt through a license for clay mining and brick burning at the study site dated to 1865 CE, explicitly requiring immediate fill. Local-scale clay pits for mud-brick production have been known about in western Europe since Roman times. However, access to the resources in the BSN channels in 1865 CE was only possible after a significant fall in groundwater tables following the regulation campaign of the Rhine system starting in the first half of the 19th century, which, in a wider context, illustrates the extent to which large-scale anthropogenic changes in the fluvioscape have cascading effects down to the local scale.

Sediments preserved in glacially overdeepened structures can provide a record of the regional Pleistocene glacial dynamics beyond the last glaciation. In order to unravel the glacial dynamics of the Isar-Loisach paleo-glacier, a cored sedimentary succession (ICDP-DOVE 5068_3_A) from an overdeepened basin near Schäftlarn, south of Munich, Germany, and an outcrop in its northern foreland (“Münchner Klettergarten” near Baierbrunn, on the southern margin of the Munich gravel plain, the “Münchner Schotterebene”) were investigated with a multi-method approach. This approach focused on single-grain feldspar luminescence dating to establish a chronological framework and on a comprehensive geophysical survey to better understand the morphology of the overdeepened basin. The Schäftlarn core is generally divided into a fine-grained basal section and a coarse-grained top section. The filling of the fine-grained basal section started in early Marine Isotope Stage (MIS) 8. The basal part of the overlying coarse-grained sediment can be attributed to late MIS 8. The “Münchner Klettergarten” outcrop to the north exhibited a similar depositional age dating to late MIS 8 and therefore corresponding to the basal part of the coarse-grained sediment in Schäftlarn. The geophysical survey revealed two cross-cutting glacial basins, with the MIS 8 basin being cut by a younger basin of undetermined age. Based on the luminescence dating results and the geophysical survey, a mid-Pleistocene landscape development model of the Isar-Loisach paleo-glacier region is presented.

AU - van der Spek, Ad AU - de Stigter, Henko AU - Wallinga, Jakob AU - Witbaard, Rob AU - Soetaert, Karline T2 - Biogeosciences AB - Abstract. Sediment transport and seabed composition can both be influenced by bioturbation and hydrodynamically driven sediment mixing and deposition. In a dynamic intertidal environment, it is challenging to distinguish the relative contribution of both processes. We aim to unravel their relative importance by combining several tracers, each having its own specific timescale and target particle size. We combined (1) 210Pb that quantifies long-term (years–decades) mixing of fine sediment fractions with (2) Chlorophyll a and (3) luminophores that both quantify short-term mixing of fine sediment fractions (days–weeks), and (4) multi-grain quartz and single-grain feldspar luminescence dating, which use the bleaching of sand grains' inherent luminescence signal by light to assess mixing of sand and thereby quantifies long-term mixing. Single grain feldspar luminescence is here for the first time applied in the intertidal environment. We compare results for a sandy and a muddy intertidal flat at the island of Texel (Wadden Sea, the Netherlands), each with their own characteristic benthic community. Recent bioturbation became apparent from Chlorophyll a and luminophore profiles: particles were rapidly reworked to a depth of decimetres. 210Pb also suggested mixing and non-local exchange of particles by bioturbation. The combination of luminescence signals suggested that after deposition, not all sand grains did resurface repeatedly and for longer time periods through bioturbation. Coarse- and fine-grained tracer profiles show the differential behaviour and reworking of the mud and sand fraction within the sediment matrix: as expected with particle-selective bioturbation, mud is preferentially bioturbated and infiltrates passively, while sand grains have a higher ability to conserve layering. Single-grain feldspar luminescence is a promising technique to demonstrate the long-term reworking of sand grains, however, in young and dynamic environments, a combination of tracers remains necessary to inform on the origin of mixing.

T2 - Radiation Measurements AB - The published literature is full of reports claiming to determine the trapping parameters – trap depth (Et, eV), frequency factor (s, s−1) and kinetic order (b) – from thermoluminescence (TL) glow curves. In recent years probably the most popular approaches employ ‘Computerized Glow Curve Deconvolution’ methods of fitting the glow curve using standard TL equations. Regrettably, most of these efforts are at best unreliable and at worst simply wrong. This paper illustrates that, in order to accept the published results with a degree of confidence, the details of the experimental method and the appropriateness of the theory used must both be examined carefully. Examples of poor experimental method include inadequate temperature control (e.g. measuring the temperature of the heater, not the sample), ignoring changes in luminescence efficiency with increasing temperature (thermal quenching), and no, or improper, consideration of the emission spectrum (i.e. whether it is constant as the temperature changes). Examples of inappropriate theory include the use of General-Order Kinetics when this is unjustified. This results from an apparent misunderstanding of TL kinetics when dealing with systems described by multiple-trap/multiple-recombination-site models. Most published analyses assume non-interactive kinetics between the various trapping and recombination sites and treat each trap as isolated from all other traps and from the recombination sites. This paper discusses these issues in detail and concludes that once the glow curves are properly obtained, deconvolution analysis should consider the potential for localized recombination (including thermally excited tunneling) and, if delocalized recombination dominates, only first-order kinetics should be used in almost all examples, with the possible exception of the highest-temperature TL peak for which second-order kinetics may apply.

Fluctuating sea levels shaped prehistoric human migration, settlement patterns, and adaptation strategies. The lower reaches of the Min River in Fujian were a major centre of activity. During the Middle to Late Neolithic, marine communities such as the Keqiutou (6500–5500 cal. a BP) and Tanshishan (5500–4300 cal. a BP) cultures flourished. However, the scarcity of earlier remains has limited understanding of Early Neolithic life before 8000 cal. a BP. We dated stratigraphic layers at the newly excavated Niutoushan site using radiocarbon dating and optically stimulated luminescence (OSL). OSL results indicate the site’s Neolithic culture layer between 9.3 ± 0.7 ka and 8.1 ± 0.5 ka, with radiocarbon dates clustering around 8300–7000 cal. a BP. Based on the younger bounds of the dating results and kernel density estimation, the Neolithic remains at the site are dated to approximately 8000–7000 cal. a BP, identifying Niutoushan as one of the earliest Neolithic sites in the region. Combined with sea-level reconstructions, the findings suggest that the rapid Early Holocene sea-level rise drove human migration along China’s eastern coast before 8000 cal. a BP. The Niutoushan culture was influenced by Neolithic cultures from northern coastal regions and potentially by those located to its south across the exposed Taiwan Strait from the Last Glacial Maximum to the Early Holocene. This points to complex interactions among Early Neolithic cultures in both northern and southern coastal China, warranting further investigation for validation.

The radiocarbon dates from the 2002–2004 excavations once indicated that the hominin occupations of this site may have persisted into the Upper Paleolithic time-range (approximately 30–50 ka); we conducted additional research to verify those dates using different techniques and materials. This paper presents new sets of accelerator mass spectrometry (AMS) and optically stimulated luminescence (OSL) dates based on the samples from our renewed excavations between 2013 and 2017. The results suggest that the Middle Paleolithic layers of Anghilak are likely to be earlier than or at least close to the current limit of AMS dating, and they may go back to as early as 55–85 ka. Accordingly, we regard the Anghilak occupations representing a late Middle Paleolithic rather than those involving the Middle-Upper Paleolithic transition or showing a robust example of the late survival of the Middle Paleolithic. At the same time, this new finding helps to develop a better chronology for the Middle Paleolithic hominin occurrences in Central Asia, when different cultural groups may have co-existed.

At Tel1 Burna, a multiperiod stratified site in the Shephelah region of central Israel, we integrate portable X‐ray fluorescence (pXRF), portable optically stimulated luminescence (pOSL), and organic residue analysis (ORA). Our aim is to assess how postdepositional processes shaped the archaeological record in Tel Burna, Israel. The results demonstrate that elemental patterns—particularly phosphorus (P), calcium (Ca), and potassium (K)—can reveal occupation surfaces and destruction layers not visible macroscopically. High Ca corresponds to chalk‐based floors, elevated K to degraded mudbrick architecture, and enriched P to domestic activity or burning. A fire‐related destruction horizon in Stratum IV is suggested by the presence of high P in the decomposed mudbrick destruction layer, elevated K in both this layer and the underlying intact mudbrick, low Ca, strong luminescence signals, and the near absence of lipids, suggesting thermal alteration of architectural materials. pOSL photon counts increase with depth and provide strong support for the stratigraphic integrity of the profile. Spatial variability, including the absence of Stratum III in downslope areas, highlights differential preservation across the site. Comparative data from regional soils reinforce the interpretation that carbonate‐rich, alkaline soils tend to retain P but allow greater K mobility. The study highlights how the integration of pXRF, pOSL, and biomolecular analysis can improve stratigraphic resolution in complex or eroded contexts, offering a rapid, non‐destructive toolkit for rescue archaeology and for identifying buried destruction events and mudbrick constructions in the southern Levant.

Technical limitations in pollen extraction and chronology have hindered comprehensive understanding of spatiotemporal patterns and their driving mechanisms. Using an improved pollen extraction method, we analyzed pollen and charcoal from three loess-paleosol sections (Huanxian, Jingchuan, and Yaoxian) to reconstruct regional vegetation history and anthropogenic impacts. Our results demonstrate that steppe vegetation (dominated by Taraxacum, Artemisia, Aster, Chenopodiaceae, Poaceae, and Hippophae) prevailed throughout the Holocene, with significant increase in forest components during the mid-Holocene. A significant ecological transition occurred approximately 2.0 ka (corresponding to the Qin-Han period), marked by significant increases in charcoal (indicating fire activities), Hippophae (reflecting shrub colonization), and Brassicaceae (demonstrating agriculturalization), revealing systematic human modification of ecosystems. Spatial analysis shows this anthropogenic impact followed the regional climate gradient, appearing earlier and more intensely in the warmer/wetter southeast (Yaoxian) than in the arid northwest (Huanxian). We propose a dual-control framework where climate primarily governed biome-scale vegetation patterns, while human activities secondarily modified species composition and ecosystem structure at local scales during the late Holocene. These findings provide new insights into long-term human-environment interactions in semi-arid regions.

Establishing reliable chronologies is essential for reconstructing dust dynamics and for correlating regional loess stratigraphies. In this study, we present the first systematically derived mass accumulation rate (MAR) dataset for six key Polish LPS, based on high‐resolution Optically Stimulated Luminescence dating of the 45–63 μm quartz fraction. Bayesian age–depth models were constructed using the Bacon software. The results demonstrate pronounced temporal and spatial variability in loess accumulation across southern Poland. All profiles show maximum MARs during MIS 2, with exceptionally high values exceeding 1000 g m −2 a −1 at Trzebnica, Tyszowce and Strzyżów sites. In contrast, Zaprężyn site exhibits lower MARs with only localized peaks. The results highlight the utility of luminescence‐derived MARs for investigating regional aeolian dynamics, while also emphasizing the methodological limitations imposed by chronological uncertainties and sampling resolution.

France AU - Marik, Madhurima AU - Serra, Elena AU - Opitz, Stephan AU - Woelki, Dominic AU - Rixhon, Gilles AU - Preusser, Frank T2 - Geochronometria AB - Rock surface luminescence dating has developed into a promising approach to constrain depositional ages of clasts. The prerequisites for its successful application are the precise determination of the clast-specific dosimetry and the sufficient pre-burial resetting of the luminescence signal into a certain depth beneath the clast-surface. Dosimetry of clasts is significantly influenced by the internal beta dose rate, which largely depends on grain-size range and internal potassium content of feldspar within rock slices. In the current study, six clasts are investigated from three distinct fluvial terraces of the Bruche River in north-eastern France. Previously published independent age control from sandy deposits of the terraces indicate depositional ages of ~12–14 ka for the youngest, ~27–35 ka for the middle, and a minimum age of ~200 ka for the oldest terrace. Clast-based multi-elevated-temperature post-IR infrared stimulated luminescence (pIR) ages show systematic deviations from age control, overestimating by ~50-150% for the youngest terrace, ~10-30% for the middle terrace, but confirming the minimum age for the oldest terrace. The present study provides methodological advancements by estimating grain-size range and K-content in feldspar grains within rock slices using µ-X-ray fluorescence and microprobe analysis, respectively. Modern clasts from the present riverbed indicate that high-temperature pIR signals retain significant residual ages in rock slices, ranging from ~2-3 ka for pIR110 over ~5-6 ka for pIR170 to ~8 ka for pIR225 signals, while IR50 residual ages remain negligible (<1 ka). This study also demonstrates the potential for using fully saturated rock slices from clast interiors to perform reliable fading correction. As the clast-based luminescence ages overestimate the corresponding ages derived from sandy deposits, this highlights the remaining limitations that must be considered for this approach.

AU - Martin, Loïc AU - Tsukamoto, Sumiko AU - Preusser, Frank AU - Niemeijer, André T2 - Scientific Reports AB - Unravelling a reliable timing of past earthquakes through luminescence dating of fault gouge depends on sufficient frictional heat during a co-seismic event to fully reset the luminescence signal. Laboratory fault-gouge production using a rotary shear apparatus has attracted interest as a method for probing the degree of signal resetting in quartz during friction experiments. However, natural fault gouges are complex, exhibiting a mixture of minerals that are specific to the host rocks. Here, we employed a host rock sample from the Alborz Mountains (Iran) and subjected it to a friction experiment without any chemical treatment, after being reset and irradiated with a known gamma dose. We performed a medium-slip velocity friction experiment with a slip velocity of 0.05 m/s and a normal stress of 12 MPa, while the temperature evolution of the gouge zone was recorded using an infrared camera. The thermographic images show a transient temperature of approximately 296 °C, with the luminescence signal resetting at a small, extremely localised slip patch, confirming the challenges involved in identifying the best spot for signal resetting. However, we identified a high-temperature signal enhancement in the thermoluminescence (TL) curves that might serve as a marker for fault-gouge formation.

Sedimentary deposits reflect past coastal environments but require precise chronological data to place evidence into a temporal context. While radiocarbon dating is widely employed, it is associated with several methodological challenges and frequently there is an absence of datable material in coastal deposits. Luminescence dating provides an important advantage over radiocarbon by directly determining the time of sediment deposition. However, this method is affected by problematic issues such as partial bleaching, bioturbation and dose rate assessment, which can lead to inaccurate age determinations. As a case study demonstrating good scientific practice in luminescence dating, we investigated deposits from the Chanthaburi Plain, Thailand, for reconstructing past coastal dynamics. Luminescence screening is used to identify potential signal disturbances and select appropriate sample positions in the drill cores. Luminescence dating was performed on 13 samples accompanied by detailed analysis regarding dose rate with a focus on water content and radioactive disequilibrium. The dated samples indicate depositional ages ranging between 7.2 and 4.6 ka. Comparison with radiocarbon ages (18 samples) reveals that plant material often represents modern roots and that molluscs tend to systematically underestimate the sedimentation age, likely due to partial recrystallisation. Our data suggest at c . 6.5 ka, a location of the coastline ~8.1 km inland from the present position. At around 4.6 ka, the coastline was about 7.2 km from the present shore. Together with previously published data, this indicates a sea‐level regression from the Middle Holocene highstand towards the Late Holocene.

T2 - Boreas AB - Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM. GM is a flat‐topped hill in the Enns Valley, Styria (Austria), rising ∼200 m above the valley floor between Mesozoic carbonates (north) and crystalline basement units (south). Crystalline bedrock (phyllite, greenschist) is overlain by subglacial, deltaic, fluvial and glaciolacustrine sediments, with soft‐sediment deformation (clastic dykes) and capped by LGM till. Outcrop, borehole, and electrical resistivity tomography data reveal a bedrock surface incised by a channel. The Middle–Late Pleistocene succession begins with the Lower Till, attributed to the Rissian glaciation (MIS 6), which reshaped a fluvially moulded bedrock surface by intense subglacial erosion, including meltwater activity. Above lies the Mitterberg Unit. The up to 100 m thick Dorf (Allo‐)Member comprises delta foresets with slumps, rare dropstones and dead‐ice contact structures, correlated to Termination II (MIS 6) by luminescence ages of 140±20 ka. The 10 m thick Zirting (Allo‐)Member records fluvial deposition. The upper Frankenbichl (Allo‐)Member consists mainly of interbedded lacustrine and deltaic sediments, showing overall aggradation. Luminescence ages of 47±8 ka suggest a lake formed in MIS 3 by a prograding alluvial fan under cold, ice‐free conditions. The lacustrine succession records alternating delta progradation and dam‐burst‐caused regression. Uppermost Frankenbichl glaciolacustrine deposits reflect glacier‐proximal settings marking the onset of Würmian Pleniglacial (MIS2) ice build‐up. The LGM till unconformably overlies the Mitterberg Unit and forms drumlins. Overall, these reconstructions link climate change, erosion and sedimentation in the Enns Valley, providing a framework for modelling Alpine glaciations and intervening greenhouse phases.

This transfer is repeatedly interrupted by storage and remobilization, complicating efforts to reconstruct erosion histories. Luminescence‐based methods, which exploit the progressive zeroing of the luminescence signals (bleaching) during transport, offer a new way to quantify sediment transit. Existing approaches, however, assume negligible lateral inputs, predicting a simple downstream decrease in luminescence signal intensity. We present new data from the Rakaia River, New Zealand Aotearoa, where observed downstream patterns deviate from such predictions and suggest an influence of local sediment supply. By using a stochastic transport‐storage model that incorporates continuous and localized inputs, we show that downstream signals reflect the balance between supply and bleaching efficiency, producing bleaching‐ or supply dominated regimes. These results demonstrate that luminescence‐based sediment tracing not only capture sediment transport dynamics in rivers but also their supply from hillslope erosion. , Plain Language Summary Rivers act like conveyor belts, moving sand from mountains to oceans, but this journey is not a simple downhill ride. It is interrupted by stages of storage and remobilization during floods, which can blur or delay the information sediments record on mountain erosion and make it harder to reconstruct past tectonic and climatic events. The timing of these stages and the distances traveled remain poorly understood. A recent approach uses luminescence, a technique measuring energy stored in mineral grains. This energy accumulates during burial and is reset, or bleached, when grains are exposed to sunlight, allowing to trace how long sediments move or rest. In theory, the luminescence signal intensity should gradually decrease as grains travel downstream. In New Zealand Aotearoa's Rakaia River, however, steep slopes, landslides, and tributaries supply fresh, unexposed particles that counteract the bleaching of the river's sediments. To explain this, we extended an existing sediment transport model to include such inputs. Our results show that whether a river's luminescence signal reflects bleaching during transport or is overprinted by new supply depends on the balance between transport conditions and external inputs. This distinction between “bleaching‐dominated” and “supply dominated” systems provides new insights for interpreting river sediment records and inferring landscape response to environmental change. , Key Points We extend a luminescence‐based sediment transport model to include lateral sediment supply from hillslopes Lateral input increases mean equivalent dose, revealing supply dominated versus bleaching‐dominated regimes Rakaia River data confirm models' outcomes, showing intermediate behavior between supply dominated and bleaching‐dominated regimes DA - 2026/04/16/ PY - 2026 DO - 10.1029/2025GL119886 DP - DOI.org (Crossref) VL - 53 IS - 7 SP - e2025GL119886 J2 - Geophysical Research Letters LA - en SN - 0094-8276, 1944-8007 UR - https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2025GL119886 Y2 - 2026/04/07/12:04:40 ER - TY - JOUR TI - Formation and Cyclicity Patterns of Dust-Enriched Quaternary Sediment Archives on the Eastern Canary Islands AU - Labahn, Jakob AU - Faust, Dominik AU - Kolb, Thomas AU - Schleicher, Anja Maria AU - Günter, Christina AU - Marburg, Carsten AU - Roettig, Christopher-Bastian T2 - Quaternary AB - By its availability and deposition dust is a key indicator for past climate variability. Due to the location in the main North African dust corridor, the Canary Islands preserve dust deposits in different geoarchives—for instance in valleys dammed by Quaternary volcanism. These basins act as sediment traps for aeolian, volcanic, and slope-derived material, forming alternating pale, carbonate-enriched (PCLs) and reddish, clay-enriched layers (RCLs). However, the extent to which these sequences retain primary dust signals remains uncertain. We examine the interpretability of locally called vega sediments by disentangling input pathways, post-depositional processes, and geomorphological controls. Two sections on Lanzarote (Teguise, Femés) and the section Vallebrón (Fuerteventura) were investigated using grain-size analysis, XRF and XRD measurements, and IRSL dating. The sequences reveal two dust components: high-intensity dust fall events forming PCLs, and persistent finer dust input preserved in RCLs through kaolinite. Many PCLs originated as loess-like deposits subsequently modified by carbonate redistribution, while clay mineral transformations complicate provenance interpretation. Archive clarity varies with geomorphology, from less distinctly layered, patchy carbonate-enriched succession at Vallebrón to continuous cyclic sequences in Teguise. Overall, these basins preserve both episodic dust events and continuous fine-grained input, offering a valuable framework for reconstructing Late Quaternary dust dynamics.

T2 - Journal of Quaternary Science AB - ABSTRACT The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with 14 of them dated by luminescence, amino acid geochronology or radiocarbon age‐estimate techniques. This remarkable fluvial archive provides insight into the past three glacial–interglacial cycles for eastern England and is ideally located geographically to inform reconstructions of past ice limits, sea level, temperature and drainage networks affecting the North Sea and Fenland. This robust chronostratigraphic framework provides a reference against which to assess previous work in the region and highlights future research directions.

AU - Mikkelsen, Naja AU - Kjær, Kurt H. T2 - Boreas AB - Wind activity is a powerful force that shapes the landscapes of deserts, coastal areas, and regions adjacent to ice sheets, and it has significant implications for human settlement. In southern Greenland, it has been proposed that the increased wind and soil erosion observed around Norse settlements (~985–1450 CE) were caused by overgrazing by animals, which ultimately contributed to the decline of the Norse culture. Alternatively, some studies have linked the observed intensification of aeolian activity to changes in large‐scale atmospheric circulation patterns in the North Atlantic. However, the timing and impact of this increased aeolian activity in southern Greenland remain uncertain due to a lack of well‐dated records. In this study, we use a lake record and optically stimulated luminescence (OSL) dating of adjacent dunes to reconstruct the Holocene history of aeolian activity at Igaliku Kujalleq (Søndre Igaliku) in southern Greenland. Our findings indicate two periods of intensified aeolian activity over the past 10 000 years: from ~500 to 1200 CE and ~1450 CE. Importantly, the peak aeolian activity observed in the Igaliku Kujalleq records was unrelated to Norse activities and their decline. Instead, we suggest that changes in the North Atlantic atmospheric circulation pattern combined with Neoglacial glacier advances led to increased katabatic wind activity and triggered increased aeolian activity from large outwash plains.

AU - Dyer-Williams, Kathleen AU - Tucker, Kathleen AU - Kopper, Martha AU - Al-Kaabi, Muntadher AU - Al-Qadhi, Okba R. T2 - Seismological Research Letters AB - Abstract Very large, weathered sand blows and related sand dikes in the Marianna area indicate that large earthquakes were centered there in the past. Radiocarbon (C14) and optically stimulated luminescence dating suggest that the liquefaction features formed during paleoearthquakes about 4.7, 5.4, 6.8, and 9.8 thousand years ago (ka) and possibly during two earlier events about &lt;19.5 and &lt;24.3 ka. Many sand blows occur along or near a northwest-oriented tonal lineament—known as the Daytona Beach lineament (DBL)—located southwest of Marianna. Supported by an independent seismic reflection study that identified a fault zone beneath the lineament, the DBL and spatially associated sand blows may be the surface expression of an active fault zone. Sand blows along the lineament at sites DB1, DBSE2, DBNW2, DBNW3, and DBNW5 are elongated in a northwest–southeast direction and have sand dikes with northwest trends. At sites DBSE2 and DBNW2, soft-sediment faults, also with northwest trends, crosscut sand dikes, displacing soil lamellae within the dikes. At one of the sites, small sand dikes were injected along the faults. Northeast of Marianna at site SF500, a compound sand blow composed of multiple depositional units formed about 6.8 ka. Located near the intersection of the White River fault zone and Eastern Reelfoot Rift Margin fault zone, the compound sand blow likely formed as the result of a sequence of large earthquakes, perhaps produced by these fault zones. Liquefaction potential analysis suggests that moment magnitude (M) 6.0–6.5 earthquakes generated by the fault zone beneath the DBL could have induced liquefaction in the Marianna area. However, larger Marianna earthquakes ranging up to M 7.5 would be required to induce liquefaction at distal sites near Blytheville and Marked Tree, Arkansas, and Tunica, Mississippi, where relatively small liquefaction features may have formed during the 4.7, 5.4, and 6.8 ka events.

The genesis of this formation has been linked to geological and paleoclimatic events in the Amazon, and its stratigraphic positioning has been controversial, mainly due to the scarcity of geochronological data. In this context, the present study focuses on the geomorphological and distributional aspects of this formation in the outcrop area, integrated with facies, stratigraphic, and geochronological data (Optically Stimulated Luminescence Dating - OSL) obtained from nine outcrops in the northeastern and northwestern portions of the Tacutu Basin. The facies association allowed relating the deposition of this formation to the proximal and distal portions of a Pleistocene alluvial fan environment, based on the gravel facies (AFC) deposited by gravitational flows approximately 82.1 ± 6.0 ka and the sandy facies (AFA) deposited by current flows between 66.6 ± 2.2 and 39.4 ± 2.7 ka, respectively. Locally, the fan deposits are overlain by aeolian facies, deposited by wind reworking approximately 2.13 ± 0.3 ka ago. The data obtained are consistent with a geographic and temporal continuum of the Quaternary coverage of the Tacutu Basin, in an alluvial setting in which gravitational flow processes evolve into areas dominated by streamflows and other pertinent processes correlatable to Late Quaternary alluvial fan systems identified in the northern Amazon. In particular, the unprecedented LOE data allow us to define the sedimentation stages of the fans, allowing them to be placed within the context of recent geological evolution of Western Amazonia.

AU - Tanski, Natalie M. AU - Woznick, Hawke T2 - Quaternary Research AB - Abstract Scanning electron microscopy (SEM) methods are widely used in the geosciences to determine grain shape and surface characteristics using SEM–secondary electron and backscatter imagery (SEM-SE/BSE) and elemental composition of minerals using SEM–energy dispersive X-ray spectroscopy (SEM-EDS). We discuss applications and best practices for utilizing widely available SEM methods for luminescence dating, including (1) checking sample purity following mineral separation, (2) imaging grain shape and surface characteristics related to weathering and transport, (3) quantifying feldspar-mineral phases in feldspar separates, and (4) determining internal potassium concentration (wt% K) in feldspars for use in estimating internal beta contribution to the dose rate for a sample. Quartz and feldspar purification checks of mineral separates require the least sample preparation and instrument time. These methods utilize the “environmental” or “low-vacuum” conditions of SEM. These conditions are less conducive to acquiring high-quality compositional data but can be used to quickly determine sample purity. Conversely, to acquire higher-quality compositional data, SEM working conditions require high vacuum and accelerating voltages. The resulting semiquantitative SEM-EDS results can be used to determine the phase composition of feldspar separates and more accurately determine the internal potassium content for dose-rate and age calculations.

This study investigates the TL and OSL emission properties of alumina substrates from resistors and inductors found in mobile phone circuit boards, with a focus on the dosimetric potential of the red Cr 3+ -related TL emission. Spectral measurements reveal three primary emission bands around 330 nm and 410 nm, attributable to F + and F centers respectively, and a dominant emission at 695 nm, characteristic of Cr 3+ . In TL, the Cr 3+ emission clearly dominates, particularly in resistors, with intensity exceeding that of the blue/UV emissions by up to two orders of magnitude. The red TL signal exhibits a linear dose response over a wide range (from mGy to >10 Gy), low intrinsic background, and fading characteristics consistent with anomalous fading (∼20.7 %/decade). Dose recovery experiments immediately after irradiation confirm accuracy within 7 %, a minor dose overestimation caused by minor desensitization. The red TL signal is optically bleachable, similar to its blue/UV counterpart. Irradiation trials with intact smartphones demonstrated that the red TL method delivers dose estimates within 25 % of the reference dose, comparable to established methods using display glass or OSL on resistors. Importantly, dose estimation using only a single resistor achieved similar sensitivity to protocols requiring ten components in the blue/UV range. These results highlight the potential of red TL for accurate, sensitive, and minimally invasive retrospective dosimetry. The method offers distinct advantages in scenarios where only few components are available and enables the prospect of non-destructive measurements. • TL and OSL emission spectra of alumina substrates of resistors and inductors. • Emission bands at 330 nm, 410 nm and 695 nm. • Investigation of the dosimetric properties of the red TL of resistors.

In this study, two representative alluvial–proluvial fan-covered soil profiles (QRZQ and YXC) from the Qinghai Lake Basin were investigated. Quartz optically stimulated luminescence (OSL) dating was combined with analyses of grain-size composition and soil organic carbon (SOC) to constrain the timing of soil development and its climatic background. The results show that the studied soil profiles are mainly characterized by Ah–As–C and Ah–A–C horizon configurations, with soil development spanning from 15.7 to 1.0 ka. The underlying alluvial–proluvial parent material of the QRZQ profile formed during the Last deglaciation, whereas the oldest OSL ages in the YXC profile occur within a weakly developed A horizon, indicating that this profile had already transitioned from a depositional environment to a pedogenic environment during the Last deglaciation. This contrast reflects staged differences between depositional and pedogenic processes within alluvial–proluvial settings. The soils were formed through upbuilding pedogenesis, in which sediment accumulation and top-down pedogenic modification proceeded concurrently. Grain-size composition and SOC characteristics further indicate that the depositional environment of the YXC profile was relatively stable. Integrating the obtained chronological results with regional climatic changes suggests that climate variability in the Qinghai Lake Basin exerted a primary control on the transformation between sedimentary processes and soil development. In particular, the Late Holocene (0–4 ka), characterized by a generally cold–dry climate accompanied by pronounced humidity fluctuations, represents an important pedogenic stage for alluvial–proluvial parent-material soils in the Qinghai Lake Basin. This study provides a robust chronological framework for further investigating the mechanisms of soil development in alluvial–proluvial environments from a climatic perspective.

The palaeolakes – Talingaryn Shal, Chavgantsyn Shal, Zuun Khuree, and Luulityn Toirom – are part of the endorheic Shereegiin Gashuun Basin. In this study, we reconstruct the local palaeogeographic and palaeoclimatic conditions from the Pleistocene to the Holocene through integrated field surveys, sedimentological profiling, and optically stimulated luminescence (OSL) dating. The sedimentation patterns reflect alternating fluvial, lacustrine and aeolian conditions that correspond to climatic oscillations and hydrological changes. OSL dating indicates that lakes in the region began to form during MIS-6 (138.3 ± 7.5 ka), and markedly expanded during MIS-5, particularly between 104 and 72 ka. The Holocene record shows evidence of episodic aridification, with dry phases dated to approximately 10.6 and 8.6 ka. In the Late Holocene, wetter conditions returned, lasting about 3.6 ka. Pollen analysis yielded limited results but recovery of cladoceran (water flea) remains in Lake Zuun Khuree indicates likely seasonality of this water body. These findings underscore the interplay of tectonic subsidence and climate-driven processes in shaping lacustrine systems across southern Mongolia. There is evidence too of early human activity, with archaeological traces being documented near the lake basins studied.

AU - Santos, Gilberto S. T2 - Quaternary Science Reviews AB - The evolution of coastal sand barriers is closely linked to sea-level fluctuations and sediment supply, which in turn are associated with climatic variations. Climate also exerts control over the development of penecontemporaneous or late-stage aeolian deposits that become superimposed on these barriers. This study examines the chronology and sedimentological features of Barrier III, a Pleistocene sandy coastal barrier with an aeolian cover, located in the northern sector of the coastal plain of Rio Grande do Sul, Brazil. The stratigraphic succession observed in three vertical sections revealed two principal depositional sequences. Depositional Sequence 1 (DS1), attributed to MIS 5e, records the superposition of shallow-marine deposits and penecontemporaneous coastal dunes formed during the transgressive–highstand interval, reflecting barrier construction under relative sea-level rise. Depositional Sequence 2 (DS2) consists of late-stage aeolian deposits that reworked antecedent DS1 dune sands under lower sea-level conditions than present. The OSL ages obtained for DS1 range from 167 ± 11 ka to 149 ± 11 ka, which are older than typically expected for MIS 5e and are interpreted as overestimated, likely due to signal saturation, enhanced cosmic-ray contribution in a low-radioactivity setting, and/or incomplete bleaching. DS2 yielded ages between 61 ± 5 ka and 141 ± 0.16 years, indicating multiple phases of Late Pleistocene to Holocene aeolian activity. Aeolian sedimentation was thus recurrent throughout the barrier evolution, but controlled by different mechanisms: in DS1, dune formation was linked to shoreline position during the MIS 5e highstand, whereas in DS2, aeolian reworking was predominantly driven by climatic variability, independent of relative sea-level oscillations. Grain-size distribution and heavy mineral data show that the aeolian sands of DS1 inherited their heavy-mineral signature from underlying shallow-marine deposits, whereas DS2 deposits represent the short-distance reworking of DS1 dunes under renewed aeolian activity and pedogenesis. These findings underscore the importance of integrating sedimentological and chronological data to reconstruct the evolutionary history of coastal systems, offering insights into how ancient sandy coastal barriers responded both to sea-level changes and to climatic forcing.

Using four sediment cores, we applied optically stimulated luminescence (OSL) dating, sedimentary facies analysis, and grain-size techniques (C-M diagram, end-member modeling), integrated with geomorphic interpretation and historical data, to reconstruct the delta’s evolutionary sequence and clarify storm surge-driven geomorphic reworking and its diagnostic indicators. Results indicate that the delta’s evolution was governed by abrupt fluvial sediment loss, intensified storm dynamics, and relative sea-level rise. The 893 AD Yellow River avulsion triggered delta abandonment (893–1482 AD), driving a shift from a fluvially dominated muddy coast to a wave-controlled sandy system. Sandy deposits initially formed at M04A and prograded landward to M03A. During the Little Ice Age (1482–1855 AD), frequent storm surges further expanded and elevated these sandy accumulations, while weak sedimentation persisted in the inland depression (B03). This differential process generated a unique plain lowland–coastal highland system, a rare geomorphic type among large river deltas that differs from classic island–continent and barrier–lagoon systems. This study elucidates the phased response of temperate monsoon abandoned deltas to millennial-scale climate change, advances theories of multi-factor coupled delta evolution, and provides scientific support for coastal protection, stability assessment, and evolutionary prediction under global warming.

A previous study applying U-Th dating of calcrete precipitates surrounding the calvaria and associated mammal teeth inferred a minimum age of 133 ± 2 ka. However, detailed age constraints on the Singa calvaria are still lacking. The Abu Hugar site, located just 35 km to the south of Singa, produced vertebrate fossils and stone artifacts previously thought to be contemporaneous with the calvaria. Here, we applied optically stimulated luminescence (OSL) dating on the fluvial sediments and radiocarbon dating on soils and shells from Singa and Abu Hugar. Small aliquots for quartz and single grains for K-feldspar were used in luminescence dating to address possible partial bleaching issue. Using a Bayesian age-depth model and assuming continuous deposition, we estimate a considerably younger burial age of 39 ± 4 ka for the Singa calvaria. Though we cannot rule out an older age, our new age estimate suggests that the Singa hominin might significantly postdate the origin of anatomically modern humans and the dispersal of Homo sapiens out of Africa. In contrast, the fluvial sediments from Abu Hugar have much older OSL ages of ∼120–210 ka for the exposed profile with the oldest fossiliferous level possibly as old as ∼315 ka. Our dating results challenge the previously assumed contemporaneity of the Singa calvaria and the faunal and lithic records of Abu Hugar, and reflect a complex Pleistocene history of Blue Nile deposition. • Luminescence dating is performed at Singa and Abu Hugar fossil sites • Singa calvaria might be as young as 39 ± 4 ka • Abu Hugar sediments have luminescence ages of ∼120–210 ka • Presumed temporal connection between Singa and Abu Hugar is challenged CY - Netherlands DA - 2026/// PY - 2026 DO - 10.1016/j.quageo.2026.101733 VL - 93 SP - 101733 EP - 101733 PB - Elsevier BV SN - 18711014 UR - https://lens.org/177-509-674-112-676 KW - Blue Nile KW - Human evolution KW - Luminescence dating KW - Pleistocene KW - Singa calvaria KW - Sudan ER - TY - JOUR TI - Multi-index analysis of climate change events recorded by loess-paleosol deposits in the upper Hanjiang River valley since MIS 3. AU - Zhang, Wentong AU - Lv, Lansong AU - Lu, Jiayu AU - Lv, Ye AU - Wang, Haiyan AU - Xu, Xu AU - Pang, Jiangli T2 - PloS one AB - The upper Hanjiang River basin has been an important area for human life and production since ancient times. Marine Isotope Stage 3 (MIS 3) is a special period of relatively warm and humid climate during the last glacial period. However, the climate record of MIS 3 in this region, especially the difference of chemical weathering characteristics between this region and the northern Loess Plateau, remains unclear. An in-depth field investigation was conducted in this study on the upper Hanjiang River valley and we found a typical loess-paleosol profile named Tuojiawan (TJW). Multi-proxy indicators including sedimentology, chronology, magnetic susceptibility, grain size, and geochemistry were used to analyze the climate change characteristics. The results show that the stratigraphic consists of fluvial deposits (T1-al1), interaction layer (T1-al2), Malan loess (L1-3), paleosol (L1-S2), Malan loess (L1-2), paleosol (L1-S1), Malan loess (L1-1), transitional loess (Lt), paleosol (S0), recent loess (L0), and modern soil (MS). The pedogenic intensity varies significantly in different layers and presents a tendency of S0 > L1-S2 > L1-S1 > Lt > L1 (L1-1, L1-2, L1-3). This indicates that MIS 3 is not a continuously dry and cold stage. TJW profile also showed a phase of gradual shift to warm-wet (11.5-8.5 ka BP), maximum warm-wet period (8.5-3.1 ka BP), and a phase of gradual shift to cool-dry (after 3.1 ka BP). Compared with the records of the Loess Plateau, the chemical weathering intensity of the warm and humid event in the upper reaches of the Hanjiang River in the late MIS 3 is different, which reveals the unique response mode of the region to global climate change and may be controlled by different monsoon subsystems.

Eight stratigraphic trenches, correlated along 350 m, reveal several pedosedimentary units strongly influenced by local topography. This study combines sedimentological and micromorphological analyses with optically stimulated luminescence (OSL) dating. For OSL ages, a correction of the water content calculation protocol was developed, accounting for long-term moisture variations during burial. Nine OSL ages from humic horizons of the Early Glacial (MIS 5d-5a) and colluvial deposits of the Lower Pleniglacial (MIS 4) represent the first robust chronological dataset for these periods in northern France. Their internal consistency and agreement with existing thermoluminescence ages on burnt flints support their reliability. Moreover, geomorphological analysis highlights intense erosional phases which are interpreted as rapid permafrost destabilisation events linked to the melting of large ice-wedge networks around 60–55 ka and 30 ka (thermokarst erosion gullies). These investigations thus enable the chronology of the loess–palaeosols and the link with associated climatic events to be refined. This leads to a spatio-temporal model describing the evolution of Last Glacial environments in Western Europe, providing a robust reference for studying the Neanderthal occupation of the area.

This study applied optically stimulated luminescence (OSL), thermoluminescence (TL), and single-grain (SG) dating techniques to sediment and burnt clay samples from the West City Gate (WCG) section and West Water Gate (WWG) section of Chengcun Han City Site. The single aliquot regenerative-dose (SAR) protocol and standardized growth curve (SGC) method were employed to determine depositional ages and evaluate the reliability of the dating approaches. Results indicate: (1) OSL ages from the WCG, 1.84 ± 0.09 ka and 2.19 ± 0.08 ka, correspond to the construction and destruction phases of the city gate, while OSL ages from WWG, 2.01 ± 0.24 ka to 6.61 ± 0.32 ka, reflecting sedimentation in the water gate and moat. (2) Consistent OSL, TL, and SG ages for burnt clay at WCG suggest a conflagration event, likely linked to warfare and site abandonment following forced migration, though abandonment appears slightly later than the recorded fall of the Minyue State. (3) Combined dating results and environmental indicators show changing sedimentary dynamics at WWG: between 7.0 and 4.0 ka, sedimentation was mainly climate driven; after 4.0 ka, human activity became dominant. The rise of the Minyue State promoted local production and cultural dissemination in the upper reaches of Min River.

In this study, six samples from four different ice-marginal positions in northern Germany were investigated to test different luminescence dating methods that account for heterogeneous bleaching of meltwater deposits. Multigrain measurements exhibited agreement between fading corrected infrared stimulated luminescence (IR) and fading corrected post-infrared IR measured at 225°C (pIRIR 225 ) ages, suggesting the studied samples were likely well bleached, as these signals bleach at different rates. Single-grain measurements showed a high proportion of saturated grains (up to ∼33%) in these samples. The single-grain results were therefore assessed using conventional single-grain analyses and the L n T n method. Accurate estimation of the overdispersion (OD) of a well-bleached grain population (σ b ) is essential for applying statistical age models. Because no suitable well-bleached analogue sample with comparable burial doses was available, σ b was estimated by combining intrinsic OD (from dose recovery tests) and extrinsic OD in quadrature. Both D e and L n / T n OD values exceeded the derived σ b values, confirming that all studied samples are poorly bleached and that the Minimum Age Model (MAM) is required. MAM ages derived from conventional single-grain and L n T n approaches are generally consistent; however, standard MAM ages tend to be slightly younger than L n T n MAM ages, likely due to truncation of the D e distribution through the exclusion of saturated grains. These finding demonstrate that (1) consistent IR 50 and pIRIR 225 ages cannot be considered a reliable indicator of well-bleached samples, and (2) σ b and overdispersion values should be determined and interpreted carefully, especially for old samples with a large number of saturated grains. We recommend applying the L n T n method at the single-grain level when dating partially-bleached samples with grains close to saturation, to obtain more reliable luminescence ages.

To examine this adaptation, we reconstructed the latest Quaternary landscape evolution around the La phob archaeological site, the earliest known Neolithic settlement in Tibet (∼4800 cal BP), using OSL and 14C dating of fluvial, alluvial, and dammed-lake sediments. The site is situated on a debris-flow-dominated alluvial fan in the Bodui Zangbo River valley, southeastern Tibet. Our results reveal valley aggradation during the Last Glacial Maximum and last deglaciation, followed by incision and the formation of multi-level fill and cut-in-fill terraces in the early Holocene. At ∼4.8 ka, a debris-flow dam created a ∼11 km2 paleolake that persisted until ∼1.2 ka, depositing thick lacustrine sediments over pre-existing terraces. The paleolake would have provided a stable water source, and settlement and agriculture emerged adjacent to it. We propose that the site's location on an alluvial fan benefited from episodic debris flows that supplied fine-grained, fertile sediments suitable for cultivation, despite geomorphic instability. After dam collapse, populations likely migrated to lacustrine sediment-covered terraces, where fertile soils sustained continued agriculture. Integrated with regional evidence, our findings indicate that recurrent river-blocking events promoted valley widening through cycles of aggradation and incision. These geomorphic processes enhanced habitable and agricultural land availability and played a key role in shaping prehistoric settlement patterns and adaptive subsistence strategies on the Tibetan Plateau.

AU - Qiu, Chunmiao AU - Yu, Zhongyuan AU - Li, Luwei AU - Wang, Wenxuan AU - Zhao, Qian AU - Zheng, Rongying AU - Yang, Yanlin T2 - Scientific reports AB - The Xinbaoan-Shacheng Fault is located in the northeastern Huai-Zhuo Basin, where the eastern Jin-Ji-Meng Plateau tectonic zone intersects the Zhangjiakou-Bohai earthquake belt at the North China Plain. As a major active structure, it shows significant Late Pleistocene (Qp3) activity, yet its slip rate and strong-earthquake recurrence behavior remain poorly constrained. In this study, satellite remote-sensing interpretation, paleoseismic trenching, detailed geological-geomorphic mapping, and Late Pleistocene chronological analysis were integrated to reconstruct its deformation features in the late Quaternary. The fault preserves a composite coseismic rupture scarp 32 km long, striking NW40°-65° and dipping southwest at ~ 70°, with a height of 1.5-3 m, and the statistical magnitude-displacement empirical relationship indicates that it corresponds to a historical earthquake of M 6¾-7. Trench evidence indicates normal-faulting kinematics, with the most recent surface-rupturing event occurring in the late Holocene, plausibly associated with the 1720 M7 Shacheng earthquake. Deformation-age relationships yield a vertical slip rate of 0.06 ± 0.01 mm/a (R² = 0.97) and a strong-earthquake recurrence interval of 3.39 ± 0.61 ka, characterized by alternating long and short cycles. These results provide robust quantitative constraints on the seismic behavior of the Xinbaoan-Shacheng Fault and offer important implications for regional tectonic evolution and seismic-hazard assessment in the Huai-Zhuo Basin and the whole North China Plain.

Lithic transformations mentioned here include innovative stone-working technologies such as prepared cores, Quina-like scrapers and possible origin of systematic blade production. These innovations provide a glance into potential changes in technological organization of lithic production that might reflect innovative modes of adaptation oriented towards changes in economy, environment and world-views of these early hominin groups. The open-air, Late Acheulian site of Jaljulia makes a significant contribution to the study of this transformative phase at the very end of the long Acheulian tradition in the Levant. The site was excavated to a relatively large extent (ca. 80m2) and the excavation yielded rich lithic assemblages of typical Late Acheulian technological components from several localities, dated to ca. 500-3/200 ka. The lithic assemblages are mostly dominated by flake-production, flake-tools, and numerous Handaxes. This paper presents the comprehensive analyses of the flint assemblages from five Jaljulia localities (Localities A-E). The results presented and discussed here are intriguing, as all five assemblages encompass components that could be regarded as forbearers of post-Acheulian industries. The use of prepared cores might signal an early appearance of the Middle Paleolithic Levallois concepts, and in order to stress this point, these cores are termed here "proto-Levallois". Quina-like scrapers and blades are prominent, possibly reflecting the early adoption of technologies that became more common in the post-Acheulian, Acheuleo-Yabrudian cultural complex of the Levant. Based on this remarkable lithic repertoire, this paper discusses possible patterns of continuity and change in lithic production from the Late Acheulian to later industries and suggests refinements to the reduction trajectories variability.

AU - Emberling, Geoff T2 - Proceedings of the National Academy of Sciences AB - The Nile River played a central role in ancient civilizations of Northeast Africa, yet its response to Holocene climate change and its impact on societies along its course remain poorly understood. Here we show how climatic and environmental changes over the past 12,500 y shaped the riverine landscape below the Nile’s Fourth Cataract and affected the Nubian empire of Kush in northern Sudan. Using 26 sediment cores dated by optically stimulated luminescence and radiocarbon, with additional chronological constraints from pottery typology, we reconstruct the evolution of the Nile near Napata, the major urban center of ancient Kush at Jebel Barkal (near present-day Karima). Napata, renowned for its pyramids, temples, and palaces, flourished from about 1070 BCE to 350 CE and is now a UNESCO World Heritage site. Our results reveal that the Early–Middle Holocene Nile deeply incised its valley, followed by widespread floodplain buildup around 4,000 y ago as rainfall and river flow patterns changed. During the Late Holocene, the Nile River near Jebel Barkal remained remarkably stable, due to its narrow valley with constrained outflow and enhanced sediment deposition from upstream energy dissipation at the cataract. This long-term stability promoted fertile floodplain development and, together with the sacred prominence of Jebel Barkal, fostered enduring settlement and ritual activity. These findings demonstrate how hydroclimatic change, geomorphic stability, and cultural adaptation were intertwined in shaping the environmental foundation of ancient Nubia.

AU - Fletcher, Mae AU - Honnold, Alex AU - Kane, Aldo AU - Sevestre, Heidi T2 - Radiation Measurements AB - Exposure ages and erosion rates determined using rock surface luminescence has the potential to revolutionalise Quaternary Scicence. However, accurately quantifying μ (the light attenuation coefficient) is a significant challenge. Our study shows how variable light attenuation properties (i.e. μ) can be for five samples taken from a small (423 m) elevation range of a near-vertical gneiss rock wall, which we would have expected to have had a shared μ value. The light attenuation properties varied on multiple scales: (i) between samples; (ii) between replicate cores; and (iii) between slices within a core. To avoid between sample variability, we need to either measure μ directly from the rock cores used to derive the exposure age or erosion rate, or prove that these samples and the sample used to calibrate μ have identical light attenuation properties. To avoid variability between replicate cores observed in samples, it may be more accurate to derive exposure ages or erosion rates using a single core with identical light attenuation properties to the sample used to calibrate μ. Finally, where possible, we should avoid rocks that have hetergeneous mixes of minerals with different opacities (lighter and darker). However, if it is not possible, we should routinely measure red-green-blue (RGB) values to link the presence of any low datapoints in the luminescence depth profiles to overlying lighter-coloured minerals that could have caused light ‘piping’. Our findings further emphasise the detailed consideration required for deriving μ to determine accurate exposure ages and erosion rates. • Samples from single gneiss rock wall across elevation range of only 423 m. • IR 50 signal bleaching front not deeper than pIRIR signals for the lighter coloured rocks. • Variable light attenuation between samples restricts calibration of μ. • Variable light attenuation between replicate cores introduces uncertainty. • Preferential bleaching of slices caused by light ‘piping’ of overlying lighter minerals.

T2 - Archaeological and Anthropological Sciences AB - Abstract While premodern hominins utilized highland landscapes in East Africa as early as 2 million years ago, the processes by which hominins first utilized southern Africa’s highest mountains - the Maloti-Drakensberg - are relatively unknown. This paper introduces a new site in these southern mountains, Likonong Shelter. The results of our luminescence dating and excavations establish Likonong as the earliest-known site in Highland Lesotho and demonstrate a hominin presence in the Maloti-Drakensberg Mountains as early as ~ 242,000 years ago. This first suite of archaeological, geochemical and sedimentological data from Likonong charts the progression of hominin-highland engagements from ephemeral encounters during interglacial Marine Isotope Stage (MIS) 7 to the intentional exploitation of the landscape under a broader range of environmental conditions. We suggest that social and demographic transformations during the Middle Pleistocene may have triggered highland occupation pulses and potentially cumulative cultural evolution, generating adaptive strategies that allowed for more sustained highland occupation during the Middle to Late Pleistocene transition (occupations dating from late MIS 6 to MIS 5c). Importantly, the stresses placed on foragers by sub-freezing temperatures, snow, and extreme resource stress would have required more innovative and collaborative solutions requiring both behavioral flexibility and the attainment of certain demographic preconditions.

K-feldspar pIRIR dating was applied to establish a reliable chronological framework, and an Undatable age–depth model was constructed. Accumulation rates (AR) declined in stages: rapid (~1.33 cm/a; ~370–260 yr BP), slower (~0.75 cm/a; ~260–130 yr BP), and slowest (~0.31 cm/a; ~130 yr BP-present). This dynamic pattern is likely influenced by a combination of regional aeolian activity variations, geomorphological evolution, and the intrinsic growth dynamics of the nebkha itself. To further understand the relationship between nebkha development and climatic conditions, a δ13C sequence was reconstructed using Tamarix plant remains preserved within the sediments. Based on shifts in leaf-level δ13C values, which indicate changes in water use efficiency, water availability over the past 370 years was inferred and divided into three main phases: relatively sufficient from 1650 to 1690, gradually decreasing during 1690–1870, and increasing again after 1870. The δ13C trend closely correlates with temperature variations derived from δ18O records of the Malan ice core. This suggests that in this hyper-arid region, the development of Tamarix nebkhas is primarily controlled by glacial meltwater and snowmelt runoff from the Kunlun Mountains, rather than by local precipitation.

We report here results from Baden-Baden 2, a newly discovered open-air site in the western Free State grasslands of South Africa that documents Middle Stone Age occupations dated to MIS 5. The lithic assemblage differs from known MIS 5 and post-MIS 5 industries and shows similarities with industries typically dated to MIS 6 (~ 191 − 130 ka). In order to geochronologically constrain the occupation of Baden-Baden 2, sediments for optically stimulated luminescence (OSL) dating were collected together with micromorphology blocks to correlate formation processes and luminescence data. Magnetic susceptibility and plant biomarker analyses were used to identify changes in sediment supply and reconstruct past environments, revealing a shift in sediment source or climate regime during the period of human occupation, which took place between 91 ± 8 ka and 75 ± 7 ka. The palaeoenvironment shows three relatively stable phases that match the three broad phases of sediment input identified. The combination of OSL and micromorphology shows extensive bioturbation due to termite activity in the whole sequence. We discuss here the issue of dating quartz grains in bioturbated contexts, using single grain analyses combined with the Finite Mixture Model. Our results suggest that sand at the site was deposited from 106 ± 8 ka, for the base of the sequence, to 120 ± 30 a, for the modern sample at the top. The Baden-Baden 2 assemblage overlaps temporally with different industries in other South African regions, underscoring the need for more systematic investigation of MIS 5 in the interior of South Africa.

To address this gap, here we present a mid-to-late-Holocene paleoflood record from the Xichen site along the Sihe River, a former major tributary of the Huaihe River. Using a multi-proxy approach that integrates grain-size distributions, geochemical element analysis, and optically stimulated luminescence (OSL) dating, we identify and reconstruct the timing and magnitude of a series of extreme overbank flood events. Four major flood episodes are recognized, dated to 4800–4600, 4000–3600, 3250–2750, and 1250–835 cal yr BP, respectively. A grain-size-based Flood Energy Index (FEI) reveals an overall decline in peak flood energy from the middle to late Holocene, but a higher background mean FEI after ∼4000 cal yr BP, indicating a shift toward more frequent moderate floods. Comparison with regional paleoflood archives and global climate proxies demonstrates that Pacific Ocean dynamics strongly modulated flood occurrence in the Yi-Shu-Si River Basin. Episodes of enhanced flooding were likely driven by La Niña-like conditions coupled with a warmer WPWP, which promoted a northward shift of the western Pacific subtropical high and intensified Meiyu rainfall over the basin. Our findings highlight the synergistic influence of the El Niño–Southern Oscillation (ENSO) and the Western Pacific Warm Pool (WPWP) on Holocene flood clustering and offer a long-term perspective for assessing future flood risk in monsoon transition zones under ongoing climate warming.

We obtained an Optically Stimulated Luminescence (OSL)–dated, multi-proxy paleoenvironmental record from the Xiabuzhuang site. This record provides new insights into the impact of environmental changes on the development of the microblade technology in the Nihewan Basin during the last deglaciation. Our results show that from 18.4 to 15.1 ka BP, the regional climate was cold and dry (MAT 4.4 ± 2.36 °C, MAP 396 ± 90.2 mm), but with a gradual warming and wetting trend with fluctuations superimposed. Based on changes in the morphology of microblade cores from the Xiabuzhuang site, we conclude that the development of a microblade technology in the Nihewan Basin was closely related to changes in the regional climate and environment. Specifically, the cold and dry climate during Heinrich Stadial 1 (HS1) triggered the southward migration of hunter-gatherer populations from Northeast Asia. We propose that this migration was the primary driver of the emergence of a wedge-shaped microblade technology in the Nihewan Basin. We also propose that the restored regional climate and ecological environment during the Bølling-Allerød (B–A) Interstadial reduced the probability of ancient human migration, which promoted the technological maturation and stabilization of wedge-shaped microblade production in the Nihewan Basin.

The Yarlung Tsangpo River in the eastern Himalaya provides an unparalleled setting to resolve this, but research has largely focused on Holocene events. Here, we extend this record into the deep past, presenting a comprehensive geomorphological and geochronological reconstruction of outburst floods extending back to ∼259 ka. We identify at least six distinct, high-magnitude outburst flood episodes based on field evidence of giant bars. Hydraulic modeling shows these events had colossal peak discharges ranging from 0.2 to 2.1 × 106 m3/s. Robust single-grain post-infrared infrared stimulated luminescence (pIRIR) dating establishes a chronology securely linked to distinct clusters: an early series associated with Marine Isotope Stage (MIS) 8 and its termination (∼259 ka, <242 ka, and ∼ 232 ka), followed by major events at ∼115 ka (MIS 5d), ∼18 ka (MIS 2), and ∼ 11 ka (Latest Pleistocene). Crucially, the stratigraphic tight coupling of flood deposits with immediately overlying paleosols provides physical evidence that these catastrophic failures were synchronous with rapid climatic transitions. This confirms a systematic causal mechanism: the advance of valley glaciers during cold stages (e.g., MIS 8, MIS 6, MIS 2) repeatedly dammed the river at the Gyaca Gorge, with catastrophic failure triggered during subsequent periods of climatic amelioration. Our findings reveal that glacial-interglacial climate cyclicity has exerted a first-order control on the pacing of the most extreme geomorphic events, fundamentally shaping the long-term landscape evolution of the world's highest mountain range.

Key proxies include mineral magnetic parameters, particle size End Member Analysis (EMA), stable carbon isotopes of organic matter associated with sediments (δ13C values), total organic carbon content (TOC), and δ13C and δ18O value from ostracod shells. Chronological control was established through luminescence and AMS 14C dating. The results reveal a dynamic interplay between the Westerlies and the Indian Summer Monsoon (ISM), with alternating phases of dominance shaping the palaeoclimate of the region. Thirteen distinct climatic zones (CZ1–CZ13) were identified within the sedimentary profile. Periods dominated by intensified Westerlies occurred during ∼40.6–38.2 ka, 34–29.4 ka, 28.5–27 ka, 24–16.5 ka, 11.9–10.3 ka, and 9.1–7.1 ka, while enhanced ISM influence was observed during 38.2–34 ka, 29.4–28.5 ka, 27–24 ka, 16.5–11.9 ka, 10.3–9.1 ka, and 7.1–1.4 ka. These climatic shifts correspond well with major global climatic events such as Heinrich Events (H1–H4), the Last Glacial Maximum (LGM), the Younger Dryas (YD), and the Holocene Climate Optimum, with cold phases (Westerlies-dominated) corresponding to Marine Isotope Stage 2 and Heinrich Stadials during MIS 3, and warm phases (ISM-dominated) aligning with Dansgaard-Oeschger interstadials and early Holocene insolation maxima. These patterns reflect the influence of both external solar insolation and internal ocean-atmosphere feedbacks, particularly fluctuations in the Atlantic Meridional Overturning Circulation (AMOC). Notably, enhanced Westerlies coincide with weakened AMOC phases. The palaeovegetation response is evident in δ13C values of organic carbon, indicating a consistent dominance of C₃ vegetation throughout colder intervals. Additionally, δ13C values from ostracod shells suggest a combination of atmospheric and aquatic CO₂ inputs to the lake, while δ18O values reflect changes in lake water balance driven by regional temperature, precipitation and evaporation dynamics.

Despite this significance, a lack of well-exposed outcrop sections has constrained our understanding of the evolution and forcing mechanisms of the EASM in the Songnen Plain, NE China. To address this critical issue, this study conducted a high-resolution analysis of magnetic susceptibility, goethite (Gt), and hematite (Hm) in the Harbin loess-paleosol sequence located in the southeastern Songnen Plain. In addition, a close-spaced OSL and ESR dating was employed, with the primary aim of unraveling the paleoclimatic significance of these proxies in the uniquely developed black paleosol regions of the cold climate. The results indicate that the black paleosol layers exhibit significantly lower values of low-frequency magnetic susceptibility (χlf), goethite (Gt) and hematite (Hm) compared to the loess layers, indicating a decoupling between these indicators and the pedogenic processes. These findings imply that gleyization has influenced the Harbin black paleosol layers during their development. Furthermore, a negative correlation was observed (R2 = 0.65 for χlf and R2 = 0.42 for Hm/Gt ratio) between the χlf and the Hm/Gt ratio of the topsoil in potential dust sources, and mean annual precipitation (MAP). Consequently, the χlf-MAP and Hm/Gt-MAP climofunctions were proposed to reconstruct the paleoprecipitation recorded by the Harbin loess-paleosol sequence. The differences in precipitation, as constructed by χlf and Hm/Gt, can be used to characterize the degree in gleyization of the black paleosol. Based on the quantitative reconstruction of paleoprecipitation and paleogleyization, the paleoclimatic evolution of the Songnen Plain since 195 ka can be categorized into three stages: from 195 to 160 ka, the East Asian summer monsoon (EASM) was strong, characterized by a cold and wet climate and a low degree of soil gleyization; from 160 ka to 123 ka, the intensity of the EASM weakened, with the warm and dry climate, as well as an increased degree of soil gleyization; after 123 ka, monsoon precipitation continued to decline, the climate became cool and dry, and the rate of permafrost melting slowed; however, from 105 to 100 ka, a modest increase in temperature and monsoon rainfall occurred, accompanied by intensified soil gleyization; in contrast, from 65 to 55 ka, the climate resembled that of the earlier cold interval. Overall, the evolution of summer monsoon precipitation in the Songnen Plain is jointly regulated by both high- and low-latitude processes. The summer solar radiation and changes in Arctic ice volume are the main factors affecting the evolution of the EASM. Additionally, the Western Pacific Subtropical High (WPSH) or El Niño-Southern Oscillation (ENSO) events also contribute to the variations in monsoon precipitation to some extent.

On remote oceanic reefs, aragonite‐to‐calcite alteration occurs during subaerial exposure, directly recording the timing of sea‐level fall. U–Th dating of coral calcite is challenging due to open‐system issues. However, following calcite formation, the accumulated thermoluminescence (TL) signal can date the initial subaerial exposure event. This study pioneers the application of isothermal thermoluminescence (ITL) dating of reef calcite from the Xisha Islands, South China Sea. ITL single‐aliquot regenerative‐dose protocol improved the precision of equivalent dose measurement. By integrating dose rate simulation within a Bayesian framework constrained by U–Th ages, we obtained ITL ages of 127.0 ± 8.0 and 138.5 ± 1.5 ka for two reef core samples, dating sea‐level lowstands to late Marine Isotope Stage 6. Our results demonstrate that ITL dating of reef calcite enables the high‐resolution chronostratigraphic reconstruction of sea‐level sequences back to at least 1.5 million years ago.

The Qaidam Basin in northwestern China hosts one of the largest yardang fields on Earth, which has been regarded as the most Mars-analogue. However, basin-scale research on the timing and forcing mechanism of yardang formation in the Qaidam Basin remains lacking. In this study, we used electron spin resonance and optically stimulated luminescence dating to determine the tectonic-scale (106-year) spatiotemporal evolution of yardangs in the basin. Our results indicate that yardang development in the Qaidam Basin commenced around 0.8 million years ago, starting in the northwest and gradually expanding southeast around 0.5−0.3 million years ago. This stepwise expansion of yardangs correlated well with the remarkable growth of Northern Hemisphere ice-sheet, which intensified the Siberian High and enhanced cold, dry prevailing winds in the region. Yardang development in the Qaidam Basin of China commenced around 0.8 million years ago, starting in the northwest and gradually expanding southeast, correlating with significant growth of the Northern Hemisphere ice-sheet, according to electron spin resonance and optically stimulated luminescence dating analysis.

T2 - Boreas AB - This study presents a detailed investigation of the Velika Vrbica loess‐palaeosol sequence, situated in the Wallachian Basin of northeastern Serbia, with the aim to reconstruct palaeoenvironmental changes spanning Marine Isotope Stages (MIS) 3 to 1. Using optically stimulated luminescence (OSL) dating, low field magnetic susceptibility (χ lf ), and mass accumulation rates (MARs), we have developed a robust geochronological framework and analysed sedimentary and environmental processes over the last glacial–interglacial cycle. The OSL chronology reveals consistent loess deposition from ~41 to 3 ka, with peak accumulation rates recorded during MIS 3 and late MIS 2. The MAR data challenge conventional models of loess formation, as higher deposition rates are observed during the interstadial MIS 3 compared to the Last Glacial Maximum. This finding suggests regional variations in aeolian activity and climate dynamics that differ from the widely accepted pattern of intensified dust deposition during colder glacial periods. The environmental magnetic record of the Velika Vrbica loess sequence presented here shows more similarities with equivalent sections in the Wallachian Basin than in the Vojvodina region. These findings contribute to the broader understanding of loess formation processes and palaeoenvironmental variability on a continental scale, reinforcing the importance of high‐resolution chronological and sedimentological studies in disentangling global vs. regional influences on past dust deposition.

In sea-floor hydrothermal deposits with barite, 226Ra and 228Ra, which substitute for Ba in barite, are the main sources of natural radiation together with their daughter nuclides. In ESR dating, the contribution of 228Ra is often ignored because it is unobservable in most samples due to its short half-life. However, this may not be appropriate for certain young samples in which 228Ra has already decayed out. In this study, we estimated the initial 228Ra activity in such barite samples, evaluated its contribution to natural radiation dose, and applied age corrections. We assumed that the initial 228Ra/226Ra ratio incorporated into barite was identical to the present-day ratio in hydrothermal fluids. This ratio was determined by gamma-ray spectrometry of Mn fibers, which was deployed on the seafloor to absorb Ra from the hydrothermal fluid. Independently, the natural radiation doses accumulated in barite extracted from the sulfide- and sulfate-rich deposits were determined by ESR. Using the estimated initial 228Ra activity, the extinct contributions of 228Ra and its daughter nuclides to the total natural dose were calculated, and age corrections were applied to barite samples collected from the Higashi-Aogashima Knoll Caldera hydrothermal field. The conventional ESR ages of two barite samples, in which 228Ra was not detected, were 973 and 357 years. After correction for the possible contribution of extinct 228Ra and its daughters, the age differences were only about 2 years. This indicates that the contribution of 228Ra is negligible in practice unless the initial 228Ra/226Ra ratio in particularly high. However, it is still necessary to investigate further if the fluid ratio may vary spatially or temporally.

Despite its notable natural, social, and economic importance, the Grande River lacks sufficient geomorphological and geochronological studies to provide a reliable landscape reconstruction over the past millennia. In this study, we propose a reconstruction of the fluvial dynamics of the middle Grande River over the last 35 ky through an integrated geomorphological analysis using satellite imagery and Digital Elevation Model (DEM) interpretations, field data collection, Optically Stimulated Luminescence (OSL) dating, and grain-size analyses of sediments. The results suggest the presence of a surface associated with a Pleistocene fluvial terrace (T1), a surface corresponding to a Holocene fluvial terrace (T2), the floodplain (FP) and paleochannel landforms, such as abandoned meanders, scars, and scroll bars. The morphogenesis of these features points to four phases: a predominantly erosive and energetic phase; base-level lowering and the abandonment of the T1 level; aggradation, lateral channel migration, and the development of the T2 surface; and the current phase, characterized by subtle channel incision and abandonment of the T2 terrace level. We conclude that the adjustments in the fluvial dynamics of the middle Grande River responded to cyclical allogenic factors followed by autogenic channel responses. While these transformations have likely occurred at the local level, their manifestations may have varied across the regional level. • A Pleistocene terrace (T1), a Holocene terrace (T2), and the floodplain were dated. • Paleochannel landforms, such as abandoned meanders, scars, and scroll bars, were mapped. • Base-level lowering/incision occurred in two phases during the last 35 ky. • Two phases of lateral migration through erosion or aggradation were also identified. • The coupling of allogenic/autogenic processes triggered these phases and paleoforms.

The combination of novel Optically Stimulated Luminescence (OSL) dating and sediment ancient DNA opens up new possibilities to study these geomorphological, ecological and agrarian changes in clastic‑carbonate landscapes. Here, we use OSL dating and sedaDNA analyses alongside traditional geoarchaeological techniques to examine potential anthropogenic and palaeoclimatic drivers of sediment transfer within a loessic-dominated dry valley with agricultural lynchets at Sint Martens-Voeren, eastern Belgium, through the late Holocene. Cultivation of loess-dominated sediments across the dry-valley hilltop occurred from the Bronze Age (1900–700 BCE), with lynchet formation on the steep valley sides occurring from later prehistory (Iron Age 700–50 BCE). Major erosion and valley bottom sedimentation began in the early medieval period (450–1000 CE) and accelerated in the medieval and post medieval periods (1000–1750 CE) in line with an intensification of arable cultivation, particularly beet and hops, the development of open three-field agrarian diversity, landscape connectivity and increased climatic variability. This pattern of late Holocene slope-sediment erosion, transfer and storage mirrors other dry valley sites in the Voer catchments, especially in relation to lynchets, and accelerations in sedimentation in other eastern Belgian fluvial catchments, driven by high-intensity palaeoagronomic systems. • The silt-clay texture of loessic sediments allow a greater understanding of clastic-carbonate landscapes. • OSL dating, sedaDNA and geochemistry enables detailed chronostratigraphical and palaeoecological modelling. • At Sint-Martens Voeren accelerated sedimentation across lynchets and valley bottom from the early medieval onwards. • Sediment transfer linked to intensification of arable cultivation, e.g. wheat, barley, oats, beet, buckwheat, hops. • OSL and sedaDNA methods allow greater precision in our understanding of coupled hillslope-floodplain headwater systems.

Quantifying their geometry and kinematics is essential for understanding the fault behavior and mechanisms driving mountain uplift and propagation of shortening. This study analyzes a flight of five deformed fluvial terraces along the Tongziba River in the eastern Qilian Shan, northeastern Tibetan Plateau, utilizing high-resolution satellite imagery−derived digital elevation models and optically stimulated luminescence dating to elucidate the kinematics and slip rate of the Minle-Damaying fault. The fault-related folding analysis indicates that the Minle-Damaying fault has a listric geometry, with the fault dip decreasing from ∼40° near the surface to 16°−18° at ∼1 km depth. Vertical uplift rates based on terrace uplift are 1.34 ± 0.21 mm/yr for terrace T5 and 1.29 ± 0.27 mm/yr for T4, while shortening rates derived from balanced cross sections reach 1.94 ± 0.25 mm/yr and 1.87 ± 0.36 mm/yr, respectively. These values exceed those estimated from near-field fault scarp measurements, indicating that localized scarp data may underestimate true deformation. The similarity of shortening rates along different segments of the North Qilian Shan fault supports the interpretation that this fault system plays a key role in accommodating crustal shortening, uplift, and northward propagation of the Qilian Shan.

Xinying Bay, located off northwestern Hainan Island, transitioned from an open shelf to an inner bay during the Pleistocene and now serves as a key archive for disentangling climatic and tectonic influences on regional source–sink dynamics. This study integrates 14 C and electron spin resonance (ESR) dating, clay mineralogy and trace and rare earth element geochemistry of sediments from Core ZKDZ01 in Xinying Bay. Results reveal three distinct provenance units. The lowermost unit (U1) contains old sedimentary components with clay mineral assemblages and trace element ratios resembling those of Red River sediments. The middle unit (U2) shows affinity to intermediate–acidic granites from Hainan Island. The upper unit (U3) reflects mixed inputs from both Hainan and the Red River. We suggest that the shift from U1 to U2, dated to ca. 639–565 ka, was driven by the termination of the middle Pleistocene transition (MPT), when post‐glacial warming and sea‐level rise intensified local weathering on Hainan while inhibiting Red River sediment supply. The subsequent shift from U2 to U3 is attributed to regional tectonic uplift associated with volcanic activity and the opening of the Qiongzhou Strait. These findings highlight the coupled influence of climate and tectonics on sediment dispersal in the northwestern South China Sea since the Pleistocene.

AU - Lian, Olav B. AU - Schaarschmidt, Maria AU - Durcan, Julie A. T2 - Geochronology AB - Abstract. Quantifying environmental radiation dose rates is an essential step in age calculation using trapped charge dating methods. A means of rapid dose rate estimation would therefore be useful for a variety of reasons, especially in contexts where rapid equivalent dose estimates are available. For instance, for informing sampling strategy, providing initial age estimates, or supporting portable luminescence studies. However, high-precision methods often used to calculate dose rates are typically time consuming and expensive and are impractical for such “range-finder” applications. Portable X-ray fluorescence (pXRF) offers a rapid means of measuring the potassium (K) concentration of sediment, although the other radionuclides typically used to calculate dose rates, uranium (U) and thorium (Th), fall beneath its detection limits at the quantities at which they are usually present in sediments. In this study, we investigate whether pXRF measurements of K concentration alone can be used to estimate total environmental dose rates. A large, global dataset of 1473 radionuclide samples is used to generate a set of regression relationships between (1) K concentration and external beta dose rate; (2) external beta and gamma dose rates; and (3) external gamma and alpha dose rates. We test the utility of these relationships by measuring the K contents of 67 sediment samples with independent, high-precision radionuclide data from a variety of contexts using pXRF. The resulting K concentrations are then converted to external dose rate estimates using these equations. A simplified set of attenuation parameters are used to correct infinite matrix dose rate estimates, and these are combined with cosmic ray and internal contributions to rapidly calculate total environmental dose rates for a range of theoretical, common luminescence-dating scenarios (such as 180-250 µm quartz that has undergone etching). Results show that pXRF can accurately measure K concentrations in a laboratory setting. The regression equations can predict external beta dose rates to a good degree of accuracy based on K content alone, whilst external gamma dose rates are predicted less accurately, and external alpha dose rates are predicted the least accurately. In combination, total estimated dose rates show good agreement with their counterparts calculated from high-precision methods, with 95 % of our results lying within uncertainties of ±10 % of unity for scenarios where the alpha dose rate contribution is assumed to be negligible. Whilst alpha dose rate contributions are predicted the least accurately, scenarios including an alpha component result in at least 80 % of predictions lying within uncertainties of ±10 % of unity. The use of simplified attenuation factors to correct estimated infinite matrix dose rates does not contribute significantly to resulting scatter. This study serves as a proof of concept that pXRF measurements, along with a set of regression equations and a simplified correction procedure, can be used to rapidly calculate range-finder environmental dose rates.

AU - Boulay, Manon AU - Lach, Philippe AU - Voinchet, Pierre T2 - Geochronology AB - Abstract. Quartz Thermoluminescence (TL), Optically Stimulated Luminescence (OSL) and Electron Spin Resonance (ESR) offer valuable quantitative tools both for understanding sediment provenance and surface processes. However, the variability of quartz sensitivity remains an issue, attributed either to the intrinsic properties of source bedrock, to processes during sediment transport and deposition, or to both. This study addresses these questions by investigating quartz from magmatic, metamorphic, and sedimentary formations in the Strengbach catchment (Vosges Massif, France). Using a combination of ESR, TL, OSL, and LA-ICPMS (Laser-Ablation Inductively Coupled Plasma Mass Spectrometry) trace element analyses, our study reveals significant relationships between quartz TL-OSL/ESR sensitivities and source bedrock characteristics, such as lithology, crystallization conditions, and deformation histories. ESR Ti-centre and TL-OSL signals are notably influenced by trace elements like Al, Li, and Ti. Quartz that underwent high pressure during metamorphism along with those located in the tectonic shear zone show both lowest TL-OSL and ESR intensities, while higher sensitivities are observed in quartz from plutonic rocks and sandstones. This suggests that (i) pressure can be one of the prevailing factors driving changes in quartz TL-OSL/ESR sensitivities (ii) enhanced quartz TL-OSL sensitivity in mature and recycled sediments (sandstones) highlight the importance of sedimentary transport and reworking on TL-OSL and ESR signals. Our results highlight the need for careful interpretation of ESR and TL-OSL signals, both for dating or sourcing, particularly in sediments derived from metamorphic terrains.

As a hallmark of early urbanism worldwide, moat systems represent sophisticated human adaptations to diverse hydrological environments. This study investigates the Chengcun Han City Site(late Qin-early Han period, 206BCE), a remarkably preserved vassal capital of the Minyue Kingdom in subtropical South China, to elucidate the dynamic interplay between anthropogenic modifications and fluvial processes in mountainous terrain. Combining cutting-edge optically stimulated luminescence (OSL) dating (employing an optimized SAR-SGC protocol for young sediments) with Landlab geomorphic modeling, we reconstruct the sedimentary evolution of this strategic moat system and its environmental context from the Pre-Qin to Han periods.Our multi-proxy analysis reveals three significant findings with global implications: First, the refined SAR-SGC dating method establishes a robust chronological framework for humid subtropical archaeological sites, addressing persistent challenges in dating young fluvial deposits across tropical regions. Second, sedimentological evidence demonstrates a Holocene transition from climate-controlled (early-mid Holocene) to anthropogenically-dominated (late Holocene) depositional regimes − a pattern echoing contemporaneous urban centers from Southeast Asian moated settlements to Roman frontier cities. Third, Landlab simulations quantitatively demonstrate that post-abandonment landscape changes (∼2.0 ka) triggered accelerated siltation and floodplain expansion, mirroring the “legacy sediment” phenomena observed in post-urban landscapes globally, from Mesoamerica to the Mediterranean. This research advances our understanding of early urban resilience by: (1) providing the first quantitative assessment of human-induced geomorphic changes in a Chinese mountainous vassal state; (2) developing transferable methodologies for studying ancient hydraulic systems in humid environments; and (3) establishing comparative frameworks to examine how emergent states worldwide negotiated environmental constraints through landscape engineering. The findings particularly illuminate the critical yet understudied role of subtropical highland zones in global narratives of early state formation and decline.

However, due to intense wind erosion, preserving sediments that record regional Cenozoic climate changes is challenging, resulting in a gap in long-term climate change research for this region. Six ancient lacustrine sand profiles in the north and west of the sandy land, protected by basalt and calcium carbonate layers, were selected for this study. Both conventional single-aliquot regenerative-dose (SAR) and SAR thermally transferred optically stimulated luminescence (TT-OSL) methods were employed for dating to establish stratigraphic chronological framework. Conventional SAR yielded underestimated OSL ages for lacustrine sands due to signal saturation. In contrast, TT-OSL did not reach saturation during testing, providing a stratigraphic chronological framework for the sandy land extending back to 606 ka, the oldest stratigraphic age obtained thus far in this sandy land using OSL dating. Combined with grain size and quartz grain surface morphology, the middle Pleistocene climate was revealed to have undergone warm-humid (606–480 ka), cold-dry (457–412 ka), warm-humid (400 ka), and cold-dry (290–247 ka) phases. This updates previous records of the Late Quaternary lacustrine phases of the Inner Mongolia Plateau. Based on altitude, landforms, and stratigraphic sediment records, the elevation of paleo-lake surfaces is suggested to have reached 1300 m a.s.l during the late Middle Pleistocene. The spatiotemporal evolution of the lake basin was primarily controlled by regional tectonic uplift, which governed lake migration and the attainment of highstand levels. East Asian monsoon variability acted secondarily to modulate water levels within this tectonically defined framework. • Optically stimulated luminescence dating extends Otindag Dune Field chronology to ∼606 ka. • Lacustrine deposits reveal a paleo-lake level at ∼1300 m a.s.l. in the late Middle Pleistocene. • Tectonic uplift was the primary driver of lake evolution, with climate as a secondary modulator.

T2 - Archaeometry AB - This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka). Molecular dating of rodent remains provided a more exact date (32–22.5 ka cal bp). Radiocarbon dating, however, allowed us to narrow the range of cultural deposits further to two occupation periods around 31 and 27 ka cal bp. These data confirm that, on the eve of rapid cooling (LGM), the northern areas were seasonally exploited by groups of Gravettian hunters.

In this study, the metrological consequences of this stochastic-deterministic divergence are quantitatively investigated. The study's primary contribution is to deconvolve the divergence into two distinct components: a robust, inherent imprecision and a model-dependent, systematic inaccuracy. Intrinsic physical stochasticity is confirmed to be a dominant source of imprecision, generating an irreducible dose uncertainty of over 20 % that accounts for a significant fraction of single-grain overdispersion. Conversely, a systematic inaccuracy (e.g., a >50 % dose bias), initially observed in a simplified model, is demonstrated to be a methodological artifact, not a universal consequence of discreteness. It is shown that this systematic bias can be reduced to negligible levels (<1 %) by using either a more physically realistic multi-trap model or a correctly specified simple model. Based on this deconvolution, analytical protocols are assessed. An "Average-Dose-First" protocol is identified as the superior method, as it provides an accurate final dose estimate while correctly propagating measurement uncertainty. A general framework for understanding and partitioning variance in luminescence data is thereby established. Practical recommendations are provided for improving the accuracy of modern luminescence science by selecting appropriate models and using correct statistical protocols, with a strong emphasis on the critical need for model validation.

A. AU - Duller, G. A. T. AU - Roberts, H. M. T2 - Radiation Measurements AB - For luminescence research, samples are often heated prior to and/or during measurement to measure the thermoluminescence (TL) signal or to remove charge from shallow traps. The reproducibility and repeatability of luminescence measurements will be influenced by how consistently and uniformly the samples are heated, both within a single aliquot and between different readers or sample positions. While the effects of temperature lag during heating have been intensively studied, the spatial uniformity of temperature across samples has received less attention. This study presents spatially-resolved measurements of the temperature of the heating strip, a steel cup and an aluminium single grain disc in a Risø TL/OSL DA20 reader. Temperature is calculated using black body emissions from the three materials, detected with an Electron Multiplying Charge Coupled Device (EMCCD). The results show that temperature is not spatially uniform across any of the three materials, although the degree of variation differs between them. The largest temperature variation is observed across the steel cup (∼18 % at a temperature of 500 °C), followed by the heating strip (∼8 % at a temperature of 500 °C), and then the single grain disc (∼2 % at a temperature of 250 °C). The steel cup also has greater anisotropy in temperature compared to the single grain disc. This study suggests that spatial variation in temperature can be minimised by using sample holders made of materials with high thermal conductivity (e.g. aluminium or silver), and that the impact of thermal variation can be reduced by restricting samples to the central portion of a sample holder (e.g. the central 2 mm of a sample holder (i.e. ‘small aliquots’)).

AU - Spooner, Nigel A. T2 - Radiation Measurements AB - We critically examine the quartz defect pair model, within which physical explanations of quartz thermoluminescence and optically stimulated luminescence (OSL) were introduced. We address the apparent circularity of the model, in that it appears to lack an appropriate OSL terminal reaction. In particular, by appropriately analysing prior spectral OSL measurements, we demonstrate that the prominent primary peak centred at 365 nm is accompanied by a smaller secondary peak. With this insight, we proceed to extend the existing defect pair model by introducing a new OSL reaction pair which not only takes account of the secondary peak but also offsets the source of the circularity. We complete our study by introducing a configurational coordinate diagram that includes a new terminating antibonding state, the presence of which is consistent with both the measurement data and our defect pair model extension.

AU - Song, Xing T2 - Quaternary Science Reviews AB - The Xujiayao site, located in the western part of the Nihewan Basin, Hebei Province, northern China, has yielded 21 pieces of archaic hominin fossils in association with numerous stone artifacts and mammalian remains. The Xujiayao hominin remains were recently used to define a new species Homo juluensis, representing a series of fossils, such as the Xuchang, Xiahe, Penghu, Tam Ngu Hao 2, and Denisova remains. Different dating methods have been used to estimate the age of the Xujiayao hominin remains since the 1970s when the site was originally discovered. Unfortunately, the proposed ages vary in a wide range, from the middle Middle Pleistocene to the late Late Pleistocene. To refine the age of this site, we present a new dating study using both U-series and coupled ESR/U-series dating methods. Direct U-series dating on five of the Xujiayao hominin fossils provided minimum ages ranging from ∼100 to 200 ka, which are further confined by the Diffusion – Adsorption – Decay (DAD) model ages of 172 ± 3 ka and 195 ± 5 ka, and the coupled ESR/U-series ages ranging from 144 ± 10 to 211 ± 12 ka, obtained on the associated faunal remains. These new dates were integrated with some of previously published dating results by a Bayesian age model, demonstrating that the Xujiayao upper cultural layer, in which were recovered the hominin fossils, can be constrained between 138 ± 10 ka and 199 ± 8 ka, and the lower cultural layer between 205 ± 8 ka to 228 ± 17 ka, placing the hominin occupation in a period covering the marine isotope stages 7 and 6.

However, the fossil remains in this historical park have been reported by taxonomic identification to be originating from the Carboniferous–Permian period. Confirming the age of these remains using electron spin resonance (ESR) spectroscopy coupled with neutron activation analysis is necessary. Sedimentary rocks from Ban Phot Historical Park were separated into fossil shells and soils. Taxonomic identification indicated that the overall morphologies corresponded to a brachiopod, specifically Orthotichia javanapheti and Marginifera banphotensis. The chemical composition and crystal structure of the fossil shells were examined by X-ray fluorescence spectroscopy and X-ray diffractometry, respectively, revealing high silicon content and a quartz phase. All fossil shells were applied irradiation doses ranging from 0 to 15 kGy. Free radicals were measured by ESR spectroscopy to quantify the accumulated dose (AD). The results demonstrated that the free radicals comprised CO2− species derived from carbonate. The AD varied from 9298.6 ± 186.0 Gy to 9516.1 ± 190.3 Gy. Neutron activation analysis determined the concentrations of 238U, 232Th, and 40K in shells and soils for annual dose-rate (D) estimation. Thereafter, AD from ESR dating was combined with a Monte Carlo simulation to estimate fossil age. The ages obtained by ESR agreed with those derived via the Monte Carlo simulation using the DATA program, aligning with the Carboniferous period. Moreover, this age appears credible and may fill a gap in geological studies of the new historical park at Ban Phot, Phetchabun province.

To solve this issue, a multiple evaluation in terms of characteristic saturation dose (D0), radiation sensitivity (κrad.), and signal-to-noise (S/N) ratio has been employed here for ESR intensity metrics determination, presenting the most excellent dosimeter. On the basis of this method, three sandy samples taken from the gravel layers accumulated on the oldest Yellow River terraces T9, T8, and T7 have been constrained tightly. In these obtained results, the Ti Option A as the most excellent dosimeter has well determined the terrace T9, T8, and T7 at 1599 ± 269 ka, 1695 ± 176 ka, and 1364 ± 170 ka, respectively, which can be roughly correlated with the basal ages of the aeolian loess overlying directly the three terrace treads. This correlation has not only further checked the Ti Option A as the most excellent dosimeter, but also pointed out a higher reliability in chronological determination, implying that this dosimetric method can probably be widely used for the fluvial deposits dating with early Quaternary timescale.

However, chronological frameworks and technological patterns in this region remain underexplored. This study applies multiple luminescence dating techniques to establish precise age estimates for three Palaeolithic sites in the Chaohu Lake region of Anhui Province, South China. Our high-resolution geochronological results indicate site occupation from approximately 200 to 30 ka. The lower archaeological unit, containing large scrapers, cleavers, and handaxes, dates to 200–70 ka, marking the emergence of a Large Cutting Tool techno-complex during MIS 5, possibly extending into MIS 6 or 7. In contrast, the upper archaeological unit, dated to 60–30 ka, is dominated by small flakes and flaked tools, reflecting the development of lithic miniaturization and an increased reliance on high-quality raw materials during MIS 3. These findings reveal a technological shift from Acheulean large flake technology to the dominance of miniaturized flake tools from the late Middle Pleistocene to the Late Pleistocene, closely linked to environmental and ecological changes in South China.

Marked by abrupt climatic shifts, this stage is characterized by notable diversification in hominin behavior. Technological and behavioral changes co-occurred with fluctuating ecological regimes, coinciding with the transition of millennial-scale climate events at the terminus of MIS 5, forcing hominins to develop new strategies to exploit their environment. Temporal multi-proxy-based climate and environmental reconstructions from the Donggou site in the Nihewan Basin of North China offer a high-resolution archive of climatic variation for this period, providing insights into its impact on hominin adaptive strategies. Luminescence dating indicates that the Donggou site was formed between 126.1 and 70.1 ka, and hominins occupied the site from 76 to 74ka. Our results suggest that the regional climate was colder and drier than today and underwent frequent climatic fluctuations that drove environmental and landscape changes. The Donggou hominins persisted in the initial arid phase. They continued to occupy the river floodplain landscape during the mild and moist Dansgaard-Oeschger event of late MIS 5a, before the climate deterioration of the MIS 4 episode. The Donggou archaeological data revealed flexible adaptive strategies, including the effective use of high-quality lithic raw materials, an increase in retouched tools, systematic exploitation of ungulates, and the use of fire. Other sites in the region exhibited different adaptive strategies, collectively indicating hominin behavioral diversification during this period. We suggest that climate oscillation during the MIS 5–4 transition may have promoted hominins to adjust their strategies and develop solutions to challenging environments, leading to increased behavioral flexibility and capabilities when facing landscape turnover from lakeshore to river floodplain habitats after the Nihewan Old Lake dies out.

It is uncommon to find open-air sites, that preserve such intensive and recurrent human occupations in stratigraphic position over an extended time range, which underscores the complex nature of the site. Excavations carried out between 2017 and 2019 have enabled the integration of El Sotillo into the broader geological and geomorphological context of the area. They have also made it possible to establish the stratigraphic sequence, document its archaeological complexity, and obtain numerical dates that define its chronology. This paper presents the analysis of the most recent Acheulean assemblage, located in Level 4 of the site's Northern Sector. We compare its techno-typological features with those of the assemblage from Level 5 of the Southern Sector, previously published, highlighting both parallels and divergences. Finally, we discuss the overall structure of the site in the context of the Acheulean techno-complex at the regional and peninsular level.

Carlos T2 - Quaternary Science Reviews AB - Valdegoba Cave (Burgos, Spain) is a site of longstanding importance for studying Neanderthal behaviour and anatomy within the interior of the Iberian Peninsula. Previous research at Valdegoba has explored various aspects of Neanderthal life histories, including records of mitochondrial DNA and oral microbiomes, use of the mouth for manual tasks, and resource acquisition – particularly specialised hunting of chamois. This latest article presents significant new insights into Neanderthal use of Valdegoba Cave based on the discovery of additional human remains, analysis of unpublished lithic artifacts, and examination of new geochronology results obtained using luminescence (single-grain OSL and pIR-IRSL) dating of sediments and amino acid racemisation (AAR) dating of mammal teeth. Our combined chronological dataset indicates that Neanderthal occupation of Valdegoba's Levels 4 and 5 (Unit D) occurred within, or close to, the transition between Marine Isotope Stage (MIS) 6 and 5, most likely between ∼140 and ∼120 ka. The newly discovered fifth distal phalanx from Level 5 presents clear Neanderthal morphology characterized by the expansion of the distal region (apical tuft), which is a typical Neanderthal trait. The updated lithic analysis of Valdegoba demonstrates the technological variability of Neanderthals in the Iberian Peninsula during the MIS 6/5 transition and their ability to adapt to diverse environments and resources. Our latest findings suggests that the Neanderthal group from Valdegoba Cave employed varied strategies for territorial and subsistence management towards the end of the Middle Pleistocene and beginning of the Late Pleistocene.

A new excavation at the site Besor Dyka uncovered well-preserved archaeological layers, dated by optically stimulated luminescence to late MIS 6–early MIS 5, making it the earliest known Middle Paleolithic occupation in the Negev Desert. Stable Isotope data from the site supports this chronology and suggests a correlation with one of the Negev Humid Periods. The lithic assemblage from the site is characterized by the dominance of the unidirectional convergent Levallois reduction strategy and the systematic production of triangular end-products. These traits, commonly associated with Late Middle Paleolithic sites in the southern Levant, differ from the contemporaneous MIS 6–5 centripetal Levallois and Nubian Levallois assemblages that are found in the Negev. The Besor Dyka lithics represents a third, previously unrecognized lithic tradition in the Negev during MIS 6–5. The results present new information on human adaptation to arid environments during the Middle Paleolithic and the possible influence of humid episodes on the movement of hunter gatherers between neighboring regions. The findings also emphasize that within the Middle Paleolithic of the southern Levant, the dominance of a specific Levallois strategy alone cannot reliably be used as a chronological marker.

T2 - Journal of Archaeological Science: Reports AB - The settlement strategies of ancient humans in extreme high-altitude regions have long been a central focus of academic research. Previous studies at five Nuomuhong sites suggested a subsistence strategy based on barley cultivation alongside the herding of yaks and sheep. However, it remains unclear whether this barley-oriented economy represents a regional or a site-specific phenomenon. This study aims to address this question through the excavation of the Naren site, a newly discovered Nuomuhong culture (3400–2450 cal BP) in the Chaka Salt Lake (CSL) basin on the eastern margin of the Qaidam Basin. Excavations unearthed a wealth of cultural remains, including pottery sherds, charcoal fragments, carbonized plant seeds, and animal bones. Results from three dating methods—quartz SAR OSL, feldspar pIRIR290, and AMS 14C—indicate human occupation at the site between approximately 3000 and 3300 cal BP. Archaeobotanical analysis identified a total of 465 carbonized plant seeds, comprising 405 crop grains predominantly of barley, along with some wheat. This crop assemblage aligns with patterns observed at five previously studied Nuomuhong sites. These results demonstrate that barley was the primary cereal cultivated by the Nuomuhong people in the high-altitude, cold, and arid environment of the Qaidam Basin. The Nuomuhong Culture facilitated permanent settlement in this high-altitude region through the adoption of a subsistence strategy focused on barley, supplemented with wheat, broomcorn millet, and foxtail millet.

A multidisciplinary investigation – combining building techniques with chaîne opératoire analysis, excavation data, human osteological evidence and scientific dating – reveals at least four distinct phases of use. Optically stimulated luminescence (OSL) dating of sediments indicates that the dolmen was initially constructed and used during the Early Bronze Age (EBA) IB/II and III-IV periods, while a series of calibrated radiocarbon determinations from human remains points to three subsequent episodes of reuse between 3100 BCE and 800 BCE. The limited but significant human assemblage, associated artefacts, and architectural modifications suggest that ST_30 functioned either as a continuous memorial space or, more plausibly, as a funerary monument periodically reactivated over more than a millennium. These results refine the chronological framework for dolmen construction and use in the western Irbid region and highlight the complexity of their cultural biographies.

Some research used different dating methods to cross-validate the age determinations. However, age discrepancies between radiocarbon (14C) and luminescence dating for the same section have been increasingly revealed, which have cast doubt on the reliability of these two methods in ACA. Specifically, during the late Holocene, comparative analyses of these two methods in this region remains less investigated. In this study, we dated the BST loess section at the northern piedmont of Kunlun Mountains in ACA, using the post-infrared infrared stimulated luminescence (pIRIR) signal of both medium-grained (38–63 μm) and coarse-grained (63–100 μm) K-feldspar mineral. The reliability of the dating procedures and results was verified through standard internal checks and evaluation criteria. The results show that the luminescence ages of the medium and coarse grains are basically consistent, and both are in excellent agreement with the published 14C ages of charcoals. In addition, the stable carbon isotope of organic matter (δ13Corg) of BST loess section was measured to infer the moisture variations. Our study suggests that (1) Loess of the BST section deposited since the late Holocene (∼3.6 ka), with the dust accumulation rate (DAR) substantially higher than that of loess elsewhere; (2) Humidity of this region gradually increased since∼2 ka as reflected by δ13Corg; (3) Luminescence dating methods are highly valuable for providing age control for late Holocene loess in ACA.

This study investigates landslides along the volcanic plateaus adjacent to the Sarmiento Basin in eastern Patagonia, occupied by Lakes Musters and Colhúe Huapi, an area characterized by significant Late Quaternary lake-level fluctuations. The region hosts extensive rotational and flow-type landslides, including some of the largest documented in Patagonia, with lengths exceeding 16 km. Using geomorphic mapping, luminescence dating of paleoshorelines, cosmogenic 36Cl exposure dating of landslide scarps and deposits, and DInSAR analysis of recent ground deformation, we reconstruct a prolonged history of slope failures spanning >3Ma to the Holocene. We provide the first absolute age constraints for paleolake Sarmiento, revealing highstands during the Last Glacial Maximum (LGM) and Early to Middle Holocene. The most recent major phase of landsliding occurred after the younger lake highstand, suggesting that Early to Middle Holocene flooding of the basin—likely linked to capture of the Río Senguer—together with wetter climatic conditions, may have triggered renewed slope instability. Pre-Holocene landslide ages remain less well constrained. However, failures from high mesas disconnected from modern lake shores yield significantly older exposure ages (≥105 yr) compared to landslides along recent lake margins and valleys (∼104 yr). We propose that episodic wetter conditions and lake-level rises driven by enhanced Andean runoff or drainage reorganizations, periodically increased pore pressures in escarpments. This promoted slope failure within a landscape that has remained largely arid since at least the Pliocene.

However, the formation mechanisms of ancient landslides remain poorly understood due to the lack of detailed landslide inventories and chronological constraints. In this study, we present a systematic investigation of large-scale landslides in the Meigu River Basin (MRB), located on the eastern margin of the Tibetan Plateau in southwest China. Using high–spatiotemporal-resolution remote-sensing imagery, field verification, and a series of radiometric dates, we aim to examine the potential triggers of regional landslide activity. The results show that large-scale ancient landslides were mainly controlled by active faults, folds, joints, and soft interlayers, which rendered rock groups susceptible to movement. The integration of radiocarbon (14C) and optically stimulated luminescence (OSL) dating indicates that the MRB landslides developed during three main periods: the last glacial (66–40 ka), the late Pleistocene to early Holocene (20–9 ka), and the middle to late Holocene (6–0.2 ka). These results suggest a close coupling between large-scale ancient landslide formation and climatic fluctuations. Overall, this study highlights that geological controls and climatic triggers were the two key factors governing large-scale landslide development in the region.

AU - Toms, Phillip S. AU - Grenfell, Michael C. AU - Humphries, Marc S. T2 - Quaternary International AB - Existing research examining tributary blocked-valley lake and wetland development upon the Mfolozi River floodplain (South African east coast) has highlighted the potential for blocked-valley lakes to act as mainstem palaeoflood archives. Sand and silt units preserved within the organic deposits of these floodplain-impounded features represent relatively large flood events and provide an opportunity to establish the frequency of extreme flooding in the region beyond the timespan of instrumental and historical records, thereby helping to reduce uncertainty around future tropical cyclone activity in a warming world. However, absolute age estimates for these sequences have been limited to radiocarbon dating of organic units, restricting flood history reconstruction. This study had two inter-related aims. Firstly, to evaluate the use of optically stimulated luminescence (OSL) dating for chronicling clastic sediments associated with the floodplain's blocked-valley lakes. Secondly, in combination with radiocarbon dating and Bayesian age-depth modelling, to reconstruct flood history across three sites on the Mfolozi floodplain and investigate the climatic factors that drove past extreme flooding in the region. The Finite Mixture Model (FMM) applied to single grain OSL data was identified as the most suitable equivalent dose (De) model, producing age estimates that either aligned with historical records and/or accounted for the largest population of grains with a common dose. The deposition models developed provide evidence for the occurrence of multiple extreme floods since the first event identified at 7.2 ka, providing the first long-term flood record for the region. Comparison of the Mfolozi palaeoflood record with independent sedimentary hydroclimatic evidence from the region indicates a historical tendency for more frequent extreme floods during weakened El Niño conditions (i.e., La Niña or neutral ENSO phases). This suggests that variations in ENSO conditions through the mid-to-late Holocene likely played a fundamental role in triggering extreme flooding along South Africa's east coast.

AU - Fiebig, Markus T2 - Quaternary International AB - Despite a long history of geologic research in the European Eastern Alps, Quaternary landscape evolution before the Last Glacial Maximum (LGM) remains poorly constrained due to the scarcity of dated sedimentary archives, particularly in inneralpine regions. In this study, we reinvestigate an 880-m-long drill core from Bad Aussee (Styria, Austria), originally drilled for salt exploration. Sedimentological, geochemical, and geochronological analyses allow us to identify three major depositional units spanning the last two glacial cycles. The succession starts with glaciolacustrine deposition during the penultimate glaciation (Rissian, Marine Isotope Stage 6), consisting mainly of glacially sourced material of local provenance (carbonates and evaporites). In contrast, the >500-m-thick overlying deltaic and lacustrine deposits (Early to Middle Würmian) indicate a source area dominated by crystalline rocks. This observation suggests that, for a prolonged period between the Last Interglacial and the Late Würmian (MIS 2), the Upper Enns Valley drained into today's Traun Valley, crossing the present-day drainage divide. Furthermore, the lack of glacial deposits indicates that glacial advances during this phase did not reach the Bad Aussee Basin. On top of the succession, a carbonate-rich subglacial till can be attributed to the LGM. While questions regarding the formation mechanism of this exceptionally deep and confined Quaternary basin remain, our results challenge the previously suggested model of subglacial dissolution and subsequent formation and rapid infill of a deep lake. Salt-related syndepositional subsidence could serve as an alternative explanation for the observed stratigraphy.

The initial and primary sliding event of the Shaweitaizi landslide occurred on the right bank. The “hard-over-soft” stratigraphic configuration, potential seismic activity, and dip-slope structure all contributed to the landslide's occurrence. Besides, field observations revealed a secondary landslide near the Malutang Fault within the Tangtang formations (Pt2h) and Qinglongshan formations (Pt2q). This secondary failure may have been closely linked to channel erosion processes following the collapse of the Shaweitaizi landslide dam. Based on field investigations, the upstream lacustrine sediments, which extend approximately 50 km from Panzhihua to Jinpingzi, exhibit a maximum thickness of over 50 m. The top elevations of these sediments range from 962 m to 1038 m. Radiocarbon (14C) and Optically Stimulated Luminescence (OSL) chronologies suggest a sedimentation period of approximately 10,000 to 30,000 years, with damming initiation at 60,000 to 34,000 a BP and breaching at ~20,000 a BP. The calculated inundation extent of the landslide-dammed lake indicates a backwater length of approximately 338 km, closely matching the spatial distribution of lacustrine sediments identified during field investigations. Based on the presence of continuous terrace-like platforms on both banks of the river between the Shaweitaizi landslide and Panzhihua, the lake likely reached a stable water level around 1100 m. The eventual failure of the dam was most likely associated with a catastrophic flood event, as evidenced by thick and laterally continuous sand or sand–pebble layers abruptly overlying the lacustrine deposits. Together, these findings support the interpretation of a single, landslide-induced depositional episode that shaped the upstream lacustrine stratigraphy, offering valuable insights into geohazard processes in tectonically active fluvial environments.

Here, we mapped terrace features from three rivers draining the peri-Adriatic belt by combining semiautomatic extraction of tread surfaces from high-resolution digital terrain models with detailed mapping of associated basal strath surfaces using the 1:10,000 geological map. Nine luminescence and radiocarbon ages, integrated with sedimentological data and published chronologies, refine the timing of terrace formation for the region. Although age uncertainties are substantial, cumulative probability distributions indicate that many terrace deposits broadly coincide with late-interglacial cooling and glacial conditions, whereas older terraces show more dispersed ages. Age-elevation modeling reveals spatially variable uplift histories since ~1 million years ago, consistent with differential crustal uplift or long-strike variations in anticline growth. Overall, these results provide new constraints on the interplay between climate and tectonics shaping the peri-Adriatic landscape.

AU - Kumar, Pankaj AU - Sharma, Rajveer AU - Jaiswal, Manoj Kumar T2 - Quaternary International AB - The collision between the Indian and Eurasian plates led to the development of foreland-propagating fold-and-thrust belts. The Main Frontal Thrust (MFT) is considered the youngest. However, geologists have also identified faults younger than the MFT in the foreland of the western Himalaya, which they named Piedmont faults. In this study, a similar fault is proposed in the foreland of the Darjeeling-Sikkim Himalaya, known as the Baradighi fault. Nakata (1972) first reported the scarp associated with the Baradighi fault, but little research has been conducted to understand its evolution. Sediment dating was performed using Optically Stimulated Luminescence (OSL) and 14C Accelerator Mass Spectrometry (AMS) methods. Results show that the activity on the Baradighi fault began around 30 ka and is still active. The region has traditionally been known as the ‘Siwalik Gap’ due to the absence of the Siwaliks, but this work reports the presence of the Siwaliks in the area. Geomorphic indices were used to assess the relative tectonic activity. The Asymmetry Factor indicated that most river basins are tilted westward. Basin elongation ratios suggest that not only E-W faults influence drainage, but also some active N-S aligned lineaments affect the fluvial system in the region. However, the hypsometric curve (HC) and index (HI) suggest that the area is not tectonically active, as most rivers originate in the unconsolidated Quaternary sediments, which are easily eroded. Consequently, deformation features caused by active tectonics have either been eroded or buried beneath river-deposited sediments.

However, studies utilizing sedimentary records to understand these dynamics remain limited. This study investigates the rapid siltation of the palaeo-Qinglong channel during the Song dynasty and its relationship to climate change. Three cores were drilled in the lower reaches of the palaeo-Wusong River, and surface sediment samples were collected from the Huangpu River in the southern plain of the Yangtze Delta. Using AMS 14 C and optically stimulated luminescence (OSL) dating, sedimentological and alkaline earth metal analyses, this study explores the formation and silting history of the palaeo-Qinglong channel. The results indicate that the palaeo-channel was formed about 2,000 years ago as a fluvial-dominated channel but transitioned into a tide-dominated environment, as evidenced by the prevalence of muddy sediments. Rapid siltation occurred during the 11th and 12th centuries, characterized by increased Sr content and Sr/Ba ratio, which indicate intensified salinity intrusion. This rapid infilling is attributed to the increased storm frequency during the Song dynasty, which enhanced the mud import into the channel. A brief period of strengthened fluvial processes, characterized by the occurrence of sandy bedload in the sediments near Qinglong Town, likely reflects channel regulation projects undertaken along the lower reaches of the palaeo-Wusong River during the Northern Song dynasty. The findings suggest that the climate warming and relative sea-level rise during the Medieval Climate Anomaly (MCA) amplified tidal processes in the lower palaeo-Wusong River. This study provides valuable insights into fluvial-marine interactions and their implications for managing ports and navigation channels in tidally influenced estuaries.

Most of the studied Boreal marine beds are composed of two units, with the dark grey fossiliferous silty clay overlain by beige and light grey loose (sand and gravel) variously bedded material. Presumably high sedimentation rates due to the proximity to the Kuloi Plateau resulted in the low total abundance of microfossils and their relatively monotonous taxonomic composition. Benthic foraminifers display almost equal proportions and coexistence of ecologically different groups occurring in the Arctic shelf seas, from shallow inner shelf inhabitants to relatively deep-water ones. Rare ostracods are represented by typical dwellers of the Arctic mid-outer shelf areas. Similar to benthic foraminifers, dinocysts show a mixture of heterotrophic, including cryophilic, and autotrophic forms. The constant presence of freshwater green algae points to river runoff influence. Findings of rare polar and subpolar planktonic foraminifers together with benthic foraminifer species Cassidulina neoteretis allow assuming periodical inflows of subsurface Atlantic-derived water. Altogether, this gives evidence for an Arctic-type marine basin likely corresponding to the early stage of the transgression probably including the local highstand prior to regression. The age assignment of these beds is supported by OSL dates from overlying sandy layers generally ranging between 140 and 87 ka, with possibly older (MIS 7) age in one of the Zimnii Coast sections. The cross-correlation through the Northern Eurasia enables us to state that the common characteristic of the Last Interglacial (LIG) marine sedimentary succession is its two-unit structure. The lower unit corresponds to the early stage of inundation, the upper indicates the littoral sedimentary setting during the stillstand and regressive stage. The substantial range of available dates from 160 to 80 ka, encompassing the end of the MIS 6 glaciation, its degradation, and part of the MIS 5 stage, precludes precise determination of the duration of the Boreal transgression. The “gap” in the occurrence of the LIG marine deposits in the northeastern Eurasia along the Laptev and western East Siberian coasts might be related to the formation and existence of the glacioisostatic forebulge at the periphery of the MIS 6 ice sheets in combination with local neotectonic movements.

AU - Silva, Thais A. AU - Sawakuchi, Andre O. AU - Lopes, Renato P. T2 - Quaternary International AB - Pleistocene coastal barriers are important sedimentary archives of environmental and climatic change, although their internal stratigraphy is often obscured by pedogenesis or post-depositional reworking. Yet, these overprints can also preserve valuable evidence of superimposed climate variations. This study investigates the internal organization and late-phase aeolian activity of the Pleistocene-aged Barriers I, II, and III in the southern Brazilian Coastal Plain through a multiproxy approach integrating granulometry, magnetic susceptibility, geochemical markers (Fe2O3, TiO2, Zr), luminescence sensitivity, and optically stimulated luminescence (OSL) dating. High-resolution profiles reveal vertically compartmentalized successions. In Barriers I and III, diffuse transitions separate two units, with upper layers showing geochemical depletion in Fe2O3 and TiO2, improved grain-size sorting, and increased luminescence sensitivity. Barrier II, in turn, displays a clearer bipartite organization. Despite differences in expression, OSL ages from the upper units cluster in key intervals (38–34 ka, 22–16 ka, 12–8 ka), coinciding with Late Pleistocene–Early Holocene phases of climatic instability. These periods likely represent regionally widespread aeolian reactivation driven by reduced vegetation cover and atmospheric reorganization, followed by rapid stabilization under wetter conditions. Although post-depositional processes obscure some signals, OSL chronology provides the primary framework for identifying depositional hiatuses and late aeolian phases, while sedimentological, geochemical, and magnetic proxies reveal subtle internal boundaries within seemingly homogeneous deposits.

The aim of the study is to reconstruct Holocene RSL changes in the middle part of the Polish coast. To develop the RSL curve for the study area, 290 RSL data points were used. From these, 184 data points (32.7 %) are terrestrial limiting points (TLP), and 106 data points (18.8 %) are marine limiting points (MLP). The data allow for reconstructing water-level changes for the last 10.5 ka b2k, i.e., for the stages of Ancylus Lake and Littorina Sea, starting from an elevation of ca. 28 m below present sea level (b.s.l.). In the period 10.5–10.2 ky b2k, a fast water level rise (Ancylus transgression) occurred with an average rate of ca. 30 mm/yr. About 10.2 ky b2k, the water level reached ca. 19 m b.s.l. The formation of a drainage channel in the area of the present Belt Sea resulted in a regression of the water level of Ancylus Lake to 24 m b.s.l., with an average rate of ca. 12.5 mm/yr, in the period 10.2–9.8 ky b2k. After the connection of the Baltic with the ocean 9.8 ky b2k, during the period 9.8–8.0 ky b2k, a fast sea level rise (Littorina transgression) occurred in the study area. An average rate of water level rise during the Littorina transgression was ca. 9.4 mm/yr. The period 8.0–6.0 ky b2k is characterized by gradual decrease of the rate of sea level rise. Between 8.0 and 7.0 ky b2k sea level rose with average rate ca. 3 mm/yr, and ca. 1 mm/yr between 7.0 and 6.0 ky b2k. Over the last 6.0 ky, the rate of sea-level rise has been slower, and it was ca. 0.5 mm/yr. Taking into account similarities to other regions of the Baltic Sea and the world ocean, it can be concluded that sea-level changes in the study area in the last 9.8 ky have been eustatic in nature.

T2 - Geomorphology AB - Aeolianite and colluvial deposits at coastal outcrops located at the base of an energetic and structurally complex coastal slope have been examined in northwestern Mallorca (Balearic Islands, Western Mediterranean). A chronological framework has been established using Optically Stimulated Luminescence (OSL) dating. Due to the intensive weathering and bioturbation of the aeolianites, OSL dates have been obtained from the fine-grained polyminerals found in the colluvial paleosoils interbedded between the aeolianite layers. This limitation does not stem from the scarcity of quartz, but rather from the fact that the available quartz grains have been reworked from underlying strata and are, therefore, not chronologically reliable. The outcrop reveals a complex interaction between aeolian and colluvial deposition, and both dating and facies analysis have identified four episodes of aeolian activity during Marine Isotope Stages 5 to2 (MIS5 to MIS2). The data suggest that aeolian transport and dune formation were particularly intense during global colder climatic intervals, coinciding with low sea levels, while colluvial deposits correspond to more humid conditions. Given that the outcrop architecture and its elevation relative to present sea level (i.e., the altitude at which it is situated in relation to the modern shoreline) are comparable to those of other outcrops in structurally stable areas of the island, it is inferred that the northwestern side of the Tramuntana Range has remained relatively stable since MIS 5.

T2 - Aeolian Research AB - Well-preserved stabilized parabolic dunes occur in the Albany Pine Bush (APB), New York State, northeastern USA. This area was glaciated by the Laurentide Ice Sheet (LIS) and subsequently inundated by glacial Lake Albany until ∼ 13.0 ka. Glaciofluvial and glaciolacustrine deposits provided source sediments for dunes, which migrated towards the east-southeast. This integrated study addresses the morphology, grain mineralogy and micromorphology, stratigraphy, and chronology of a stabilized parabolic dune in the APB. The dune was active from 12.5–11.0 ka and was formed from locally-derived fluvial sediments that are slightly older (ca. 13.3–12.5 ka). The dune sands and underlying fluvial sediments are both texturally and mineralogically similar. Micromorphological analyses indicate that the dune quartz grains exhibit few characteristics typical of eolian transport, but inherently retain features of subaqueous origin. Consequently, both the distance and the duration of eolian transport during dune construction were very short. Dune stabilization coincided with the end of the Younger Dryas coeval with a forest transition from spruce (Picea) to pine-oak (Pinus-Quercus). The well-preserved morphology of dunes, and an absence of paleosols and stratigraphic truncations, all support dune stability throughout the Holocene, even with recurrent wildfire to which the local ecology has adapted.

AU - Cherezova, Anna A. T2 - Aeolian Research AB - The tallest aeolian landform in Europe (∼170 m above the base), the Sarykum dune complex, is located in the southwestern Caspian Depression near the Caucasus Mountains. Its morphology and evolution remain poorly studied. In this study we investigate the dune complex through a synthesis of geomorphological, geological, and geochronological methods. Our findings link its development to major regression phases of the Caspian Sea driven by climatic aridifications during the Late Pleistocene–Holocene. Optical stimulated luminescence dating indicates that dune formation began at least 60 ka during the Atelian regression, with reactivation around 11–6 ka during the Mangyshlakian regression. By the mid-Holocene, the complex had nearly reached its modern height. The Shura-Ozen’ River, which divides the dune complex in two major segments, played a significant role in the complex’s evolution, influencing aeolian sediment transport and trapping material on its banks, particularly on the left bank, where the highest Central Massif is located. Extensive vegetation now stabilizes most of the complex, except for active ridges in the Central Massif. A numerical analysis of wind potential for dune migration, based on recent meteorological data, shows that sand movement is primarily driven by self-sustaining NW–SE wind fluctuations. Paleowind analysis suggests that similar long-term wind patterns have persisted since the onset of aeolian deposition during the Atelian phase. Our study sheds new light on the Sarykum dune complex’s history and highlights its significance as a dynamic archive of climatic and geomorphic processes in the Caspian region.

Previous studies suggested that quartz OSL sensitivity is enhanced by solar exposure–burial irradiation cycles. Spatially resolved luminescence measurements and laboratory illumination–irradiation experiments were used to investigate the OSL sensitivity of quartz crystals from a granodiorite cobble and quartz grains from a fluvial sand. Quartz from the granodiorite cobble has low OSL sensitivity, showing an approximately linear sensitization path that resulted from laboratory illumination–irradiation cycles. The mean OSL sensitivity of quartz sand grains (100 grains) increased from ∼40 to 80 counts after 1260 illumination–irradiation cycles. Each grain has a specific sensitization trajectory due to illumination–irradiation cycles, suggesting that quartz crystal composition heterogeneities drive the OSL sensitization of their daughter sediment grains. Maximum OSL sensitivity of quartz sand grains is reached after illumination–irradiation cycles representing an accumulated dose of around 4000 Gy. This dose corresponds to sediment burial time of 2–4 Ma, which is unlikely to occur during a single sediment transport route. This study suggests that illumination–irradiation cycles are unable to produce quartz sand grains with OSL sensitivity up to five orders of magnitude higher than the sensitivity of parent crystals in igneous or metamorphic rocks.

In Germany, they are responsible for more than half of the economic damage caused by environmental hazards. The magnitude of the 2021 Ahr flood has far exceeded what was forecast in previous flood hazard assessments. This was due to a significant underestimation of hazards, as the former hydrological models considered instrumental discharge records exclusively. Because the recording period only began in the second half of the 20th century, high‐magnitude flood events prior to that period were not considered in flood hazard assessments. Historical flood events from written sources were also not included in official flood hazard assessments. In this study, we show the importance of geomorphological records from Ahr flood deposits for reconstructing past high‐magnitude flood events. Our chemo‐ and lithostratigraphical analysis of four recovered cores from the Ahr floodplain shows that centennial‐ to millennial‐scale high‐energy flood deposits are not the exception but the rule. The four floodplain sediment cores record the catastrophic flood of 2021 and the two historical floods of 1804 and 1910, as well as a previously unidentified flood event dated approximately to the end of the 5th century A.D. In addition, the geomorphological analysis in combination with near‐surface geophysical prospection shows that the Ahr floodplain is dominated by high‐energy flood deposits and that low to medium‐magnitude flood events are not preserved in the floodplain stratigraphy. The fluvial geomorphological record proves that the 2021 flood event is not an exception in the Ahr floodplain stratigraphy. In fact, at least three other flood events have been identified in the last 1,500 years that, based on lithostratigraphic parameters, had a comparable magnitude. The results document the high potential of floodplain archives for reconstructing high‐magnitude flood events in Central European rivers, allowing a systematic reassessment in terms of the occurrence and frequency of high‐magnitude flood events. The occurrence of the large floods in the Ahr valley does not show any clear coupling with the Central European hydroclimatic history. However, what is noticeable is that the historically documented high‐magnitude Ahr floods occur during the summer season, which is in parallel with high atmospheric moisture loads.
