Optically stimulated luminescence dating of Paleolithic sites reveals population shifts in North China during the last glacial period

open access: yes
The Greater Khingan and Yanshan mountain ranges in northern China not only constitute a significant physical obstacle to the northward movement of monsoon circulation, but also represent a natural barrier for human migration and cultural interactions ...

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Preliminary Study on the Activity of the Rupture Zone in the Eastern Segment of the Ba Co Fault in Ngari Prefecture, Tibet

open access: yesGeosciences
The lack of research on the slip behavior of the NW-trending faults in the central Tibetan Plateau constrains our understanding of the deformation models for this region.

The role of the Eastern Mediterranean in human evolution: recent results from Greece Le rôle du Bassin méditerranéen oriental dans l’évolution humaine : résultats récents en Grèce

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
The Eastern Mediterranean lies directly on the principal migration route for human groups dispersing across Africa, Europe, and Asia. It also encompasses the Balkans, where fauna and flora, as well as hominin populations, are thought to have persisted through glacial periods.

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

open access: yesArchaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Global Cooling Driving the Increase in Erosion Rates Across the Himalaya Since the Quaternary

open access: yesGeophysical Research Letters
Late Cenozoic global cooling is well documented, yet its impact on erosion rates in active mountain belts, particularly after the onset of Quaternary glaciation, remain contentious.

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

open access: yesBoreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Optically stimulated luminescence (OSL) dating of Çatalhöyük samples

open access: yes, 2020
The objective of this study was to perform Optically Stimulated Luminescence (OSL) dating on mud brick samples from different levels of the Neolithic site Çatalhöyük using both feldspars and quartz in them. At the beginning, a literature survey has been done about the dating system and the methodology of dating.

Direct measurement of the fast component of quartz optically stimulated luminescence and implications for the accuracy of optical dating

open access: yesQuaternary Geochronology, 2010
Abstract The usual practice in optical dating is to derive an equivalent dose ( D e ) (and hence age) from integration of the initial part of the measured optically stimulated luminescence (OSL) signal. This ‘bulk’ OSL signal is known to comprise several semi-independent components, each of which decays at different rates during measurement, and ...
