The first Neanderthal remains from an open-air Middle Palaeolithic site in the Levant [PDF]

, 2017
The late Middle Palaeolithic (MP) settlement patterns in the Levant included the repeated use of caves and open landscape sites. The fossil record shows that two types of hominins occupied the region during this period - Neandertals and Homo sapiens ...

Optically Stimulated Luminescence (OSL) Dating of Shallow Marine Sediments

The Quaternary Research (Daiyonki-Kenkyu), 2003
段丘堆積物の年代測定研究の一環として,光ルミネッセンス(OSL)年代測定法の浅海成堆積物への適用性を検討した.まず,石英の光曝・加熱・エッチング実験を実施し,この結果に基づく試料調整手順を示した.続いて,年代既知(酸素同位体ステージ5e～5c)の浅海成堆積物を対象として,付加線量法によるOSL年代測定を実施した.この結果,前浜堆積物および前浜～外浜遷移帯堆積物から,層位学的・地形学的に推定される離水年代とおおむね調和的な88～112kaのOSL年代値を得た.一方,後浜堆積物ではより新しく,外浜堆積物ではより古いOSL年代値が得られた.これらの結果から,前浜堆積物および前浜～外浜遷移帯堆積物中では光ブリーチングが成立していると考えられる.したがって,精度は粗いが ...

Shape Matters: Unlocking Transport Histories in Fine‐Grained Aeolian Sediments With Endmember Modeling of Size–Shape Distributions

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The transport medium, mode, energy, and distance are recorded in the grain‐size and grain‐shape distributions in a sedimentary deposit. While grain‐size analysis has long been used in sedimentology, grain‐shape analysis is increasingly recognized as a valuable tool for reconstructing sedimentary processes and palaeoenvironments.

Constraining the age of the Middle Stone Age locality of Bargny (Senegal) through a combined OSL-ESR dating approach

Quaternary Environments and Humans
The Middle Stone Age (MSA) is the major chrono-cultural phase associated with the emergence and evolution of Homo sapiens in Africa. Despite its importance, the MSA has not been evenly investigated across Africa, and West Africa in particular remains ...

Differential Mountain‐Building in the South Tian Shan Revealed by Multi‐Spatiotemporal Foreland Deformation

Tectonics, Volume 45, Issue 2, February 2026.
Abstract Understanding how spatially variable mountain‐building processes proceed within large intracontinental orogens provides critical insights into continental tectonics and regional paleoenvironmental evolution. Here, we address this issue in the central South Tian Shan (cSTS), a key transitional segment between the well‐studied eastern and ...

Single-grain dose-distribution measurements by optically stimulated luminescence using an integrated EMCCD-based system

, 2015
We report on the feasibility of assessing single-grain dose-distributions by using an EMCCD-based imaging system with complementary analysis software. Automated image-processing was successfully applied to compensate sample motion and for automated grain

Lowland river responses to intraplate tectonism and climate forcing quantified with luminescence and cosmogenic 10Be [PDF]

, 2013
Intraplate tectonism has produced large-scale folding that steers regional drainage systems, such as the 1600 km-long Cooper Ck, en route to Australia’s continental depocentre at Lake Eyre.

The power of the past: materializing collective memory at early medieval lordly centres

Early Medieval Europe, Volume 34, Issue 1, Page 34-69, February 2026.
The repurposing of earlier sites and monuments is an enduringly popular theme in early medieval archaeology, but in England it has attracted little interest among Late Saxon and early post‐Conquest studies. From the tenth century, however, an increasingly prevalent pattern is discernible of secular lords locating their power centres in relation to ...
