gamma: An R Package for Dose Rate Estimation from in-Situ Gamma-Ray Spectrometry Open
Process in-situ gamma-ray spectrometry for luminescence dating. This package allows to import, inspect and correct the energy shifts of Gamma-ray spectra. It provides methods for estimating the gamma dose rate by the use of a calibration c…

Vegetation response in SE France to the millennial-scale climate variability of the last glacial period Open
Deep-sea pollen records from the Western European margin indicate that regional vegetation oscillated between open forest and steppe during the Last Glacial period (ca. 115-27 ka), in response to the millennial scale climate variability, s…

Last Interglacial–Glacial sequence of palaeosols and calcareous slope deposits at Verteuil (Charente, southwest France) Open
The 12 m thick sequence of calcareous slope deposits and palaeosols exposed in a quarry at Verteuil (southwest France) has been studied and dated by optically stimulated luminescence. Emphasis was given to the identification and characteri…

The intrusive nature of the Châtelperronian in the Iberian Peninsula Open
Multiple factors have been proposed to explain the disappearance of Neandertals between ca. 50 and 40 kyr BP. Central to these discussions has been the identification of new techno-cultural complexes that overlap with the period of Neander…

Occupation and management of Bergerac territory between 250 and 35 Kans: testing a techno-economic overview Open
In this work, we propose to examine human activities from 72 occupations within a well-defined territory, the Bergeracois, during the Pleistocene between 250 and 35 ka. The study is based on bibliographical data stemming from programmed ex…

Thermal behaviour of organic radicals and paramagnetic centres in chert: A case study of Bergeracois brown chert, Dordogne, France Open
In order to successfully understand the complex evolution of prehistoric societies, archaeologists require absolute dating tools, which are not only accurate but also widely applicable. Thermoluminescence (TL) dating is one such approach t…

Towards an improvement of optically stimulated luminescence (OSL) age uncertainties: modelling OSL ages with systematic errors, stratigraphic constraints and radiocarbon ages using the R package BayLum Open
Statistical analysis has become increasingly important in optically stimulated luminescence (OSL) dating since it has become possible to measure signals at the single-grain scale. The accuracy of large chronological datasets can benefit fr…

24.0 kyr cal BP stone artefact from Vale da Pedra Furada, Piauí, Brazil: Techno-functional analysis Open
Current archaeological paradigm proposes that the first peopling of the Americas does not exceed the Last Glacial Maximum period. In this context, the acceptance of the anthropogenic character of the earliest stone artefacts generally rest…

Pleistocene Archaeological sites in Serra de Capivara: Manufacture and use of Lithic implements at Vale da Pedra Furada (Piauí, Brazil) Open
The research carried out to date on the lithic assemblage at the site of Vale da Pedra Furada has applied criteria to be able to differentiate between an artefact and a geofact at a technical level. It has determined how the different type…
