Deux approches conduisent à des âges OSL cohérents entre eux et bien corrélés à des dates radiocarbone.
Elles indiquent que tous les sédiments étudiés sont plus jeunes que 1500 ans ap. A partir de ces données une histoire complexe de phases de dépôt et d’incision est reconstituée sur les 500 dernières années.
The mineralogical features of the clays and age analysis of the liquefied materials were examined in the experimental studies.
Field work was carried out and laboratory experiments were performed on the samples taken from liquefied soils and clayey lacustrine sediments cut by sand and mud dykes.
Luminescence methods are now frequently used for the dating of colluvial sediments, as originally suggested by Wintle & Catt (1985) and recently reviewed by Fuchs & Lang (2009).
This article presents a case study on optically stimulated luminescence (OSL) dating of hillslope and alluvial headwater deposits from the Yzeron Basin, located at the western margin of the Rhône Valley in France.
