Étude pétroarchéologique de l'unité archéo-stratigraphique F2 de la grotte du Rond du Barry (Polignac, Haute-Loire), premiers résultats

A petroarchaeological study, based upon the concept of the evolutionary chain of silica, was undertaken on raw materials from the Badegoulian of unit F2 of the Rond du Barry cave (Polignac, Haute-Loire). Our study reveals the use of 42 types of flint from 30 known sources. These results differ from those of previous studies, both in terms of frequency of acquired raw material as well as in terms of geological and gitological variety. Raw materials were derived from up to 270 km distant but the flint used most frequently comes from semi-local sources in preference to that from local or far distant sources. This is the first detailed description of raw material gathering during the Badegoulian in the South Massif Central.
