Processus de débitage sur le Littoral Sud du Gabon au Late Stone Age : le site Oba 1

<p dir="ltr">The Oba 1 is an archaeology site discovered in 2017 near the small town of Owabatanga on the southern coast of Gabon. It has revealed chipped stone artifacts in the Final Pleistocene sands. These chipped stone artifacts dating back to the Late Stone Age include a significant amount of debitage products. products allow us to question blank production practice on this site. We base our analysis on the notion of « chaîne opératoire », not only as a concept, but also as a descriptive and analytical tool. The analysis highlights three specialized processes of blank debitage that prehistoric men at Oba 1 used according to the products they sought. The first is dedicated to the production of both flakes and blades; the second is oriented towards the production of flakes and the last is dedicated to the production of blades. These three processes allow us to observe several facts on the design and exploitation of the raw material.</p>
