Archéométrie de l’obsidienne : déchiffrer la circulation d’une matière première

Abstract

In the last fifty years obsidian provenance studies have become important in archaeology. Most of the time, an analytical characterisation is required to determine the origin of raw material. Recent advances in instrumentation offer a more flexible and rapid implementation of analyses. New challenges therefore arise for archaeometrists, archaeologists, lithicist, to integrate strategies for studying obsidian chaînes opératoires and analytical characterisation. Based on recent studies, this paper presents some statements on the current evolutions of research around the archaeometry of obsidian and the associated methodological challenges.
