Summary: The latest research on Cloggs Cave reveals that the youngest megafaunal specimens date back to 44,500-54,160 years ago, more than previously believed, aligning with the continental pattern of megafaunal extinctions. This suggests that the extinction of these megafauna could not have been caused by climate change leading into the Last Glacial Maximum.

Summary: The study of Quaternary terrestrial mammalian faunas in Jinyuan Cave, northeast China, revealed four different faunas ranging from the Late Pliocene to the late Middle Pleistocene. The development of the cave was closely associated with the tectonic evolution of the Bohai Basin, and major climatic variations during the Middle Pleistocene Transition in north China may have impacted the taxonomic abundance of mammalian faunas. Subsequently, the warm and wet interglacial climates in monsoonal East Asia provided an ecological niche for the evolution and migration of these faunas, leading to an increase in mammal diversity in the region.

Summary: Guanyindong Cave is an important Palaeolithic site in southwestern China, where the earliest Levallois artifacts in East Asia have been found. The artifacts were dated to two discrete periods approximately 160-170 thousand years ago and approximately 70-80 thousand years ago. Optical dating and previous U-series dating were used to establish chronological frameworks for the cave's excavation pits, providing insight into the occupation of the cave by hominins from approximately 180 ka to approximately 80 ka.

Summary: Since 1959, Studsvik, a Swedish nuclear research facility, has been releasing aquatic radioactive discharges in the Baltic Sea through the bay Tva center dot ren. The sediment cores of the bay were studied to investigate historical Studsvik releases, and the depth distribution of radionuclides such as 60Co, 137Cs, and 152Eu were compared with reported levels of aquatic discharges. The findings reveal the consistency between reported releases of aquatic discharges and measured sediment activity distribution, indicating the potential of using dated sediment as a tool for nuclear safeguards.

Summary: The sedimentological record in the Raciska pecina cave is well-preserved and provides valuable data on paleoenvironmental changes over the past 3.4 million years. Despite hiatuses in sedimentation typical for cave records, the study has significantly enhanced our understanding of long-lasting deposition characteristics and environmental changes in the caves. The detailed chronology created based on magnetostratigraphy and isotopic oxygen stratigraphy has correlated with various dating techniques to provide a comprehensive picture of the environmental evolution in the region.

Summary: The sedimentary environment in Vefsnfjord, Norway was significantly impacted by fallout from the Chernobyl accident, leading to higher Cs-137 inventories compared to other Norwegian fjords. Sediment supply rates were assessed at four sites using Pb-210/Ra-226 and Cs-137, with sedimentation rates ranging from 0.042 to 0.25 g cm(-2) y(-1). Well-defined Cs-137 concentration peaks served as a supplementary tool for the Pb-210 dating methods.

Summary: Previous studies have shown disagreement on the timing of the maximum extent of the Alpine glaciation during the last glacial cycle. New data and observations from the karst region of the Western Bauges in the French Alps suggest a maximum advance during Marine Isotope Stage (MIS) 4, with a smaller advance during MIS 2. The data, including U/Th dates of speleothems, provide constraints on the timing of glacial advances and help re-evaluate the maximum Alpine glaciation during the Wurmian in this part of the Western Alps.

Summary: Yanlidong is a cave site in southern China that has recently yielded a variety of vertebrate paleontological fossils. The analysis of the early stage deposits at Yanlidong revealed a diverse fauna containing both extant and extinct species. The paleoenvironmental and taphonomic analysis suggests that the site was located in a subtropical forest near water, and rodents played a significant role in the accumulation and modification of the large mammal remains. These findings provide important insights into the Early Middle Pleistocene of southern China and the faunal turnover during this period.

Summary: This study used optically stimulated luminescence (OSL) dating to determine the age of Xibaimaying site, finding that it falls within the period of 122-36 ka. The results show that the flake tool industry of the Xibaimaying site is comparable to other sites, rather than being the youngest one, explaining why it is characterized as pure flake tool culture. The study also shed new light on the sedimentary processes in the site area, revealing complex geomorphologic processes.

Summary: Fluvial sediment fingerprinting is a method that can trace the transport of sediment in rivers by studying changes in their luminescence properties. The study found that the type of rock in the source area is the main determinant of the luminescence properties of sediment in the river, while transportation distance influences local variations. Residual doses can be used to determine the erosion ability of the river, and coarse-grained sediments experience a dilution effect during transportation.

Summary: The research reveals that the Red Clays have aeolian origins. End-member modeling shows that the Red Clays consist of two components (EM1 and EM2 with mode sizes of 5.6 and 11.2 mu m, respectively). The south-eastward-fining trend suggests that the EM1 component (fine dust) was transported from North China, while the EM2 component (coarse dust) is mainly from the nearby desiccated fluvial systems of the Yangtze River.

Summary: Devi et al. (2022) suggested that post-violet infrared stimulated luminescence (pVIRSL) of K-feldspars has a near zero athermal fading rate. This study investigates the mechanism and suitability of the pVIRSL signal for dating applications. The results show that pVIRSL is a recuperated signal resulting from the eviction and recapture of charges in deep traps by violet stimulation and subsequent infrared stimulation. The pVIR-SAR protocol worked well for dating seven K-feldspar samples from various depositional environments.

Summary: Snow avalanches present a constant threat to mountainous regions worldwide, and understanding past avalanche events is crucial for managing and mitigating avalanche hazards and risks. In this study, dendrogeomorphic techniques were used to analyze 17 avalanche paths in a small region of the Fagaras Mountains. The analysis reconstructed 174 snow avalanche years across all paths and revealed widespread avalanche occurrence in the study area. The study emphasizes the importance of investigating multiple avalanche paths in a small, homogeneous area to gain a better understanding of snow avalanche activity at both path-scale and mountain range-scale.
