This work on the luminescence dating method (TL/OSL) has been carried out following the recent installation of a Risø TL/OSL-DA-20 reader. In the first step, the method has been successfully tested and applied on quartz grains (reference samples) using the Single-Aliquot Regenerative (SAR) protocol. For each sample, we made the purity test, we estimated the dose and the preheat temperature, and then...
The site of Bonneval (France) exhibits a 6m thick stratigraphical sequence in which Middle and Lower Palaeolithic artefacts were discovered. The stratigraphy of the site consists of an alternation of loess-like silt layers deposited along glacial stages, and paleosoil horizons corresponding to the vegetal stabilization of the area during interglacials. These layers hence provide past environmental...
