Résumé En

The province of Ogooué-Maritime has been known to the field of archaeology since the 1980s by LANA researchers, under the impetus of Lazare Digombé, Michel Locko and their team(s). A little more than 30 years after the first research missions, surface collections not far from the Perenco company's hydrocarbon processing plant, Batanga Centrale 2, provided the archaeological documentation selected for this work. This technological study made it possible to determine a chain of operations adapted to the production of flakes from rolled flint plates and rare ovoid pebbles. The debitage is essentially represented with different operating schemes (unipolar, bipolar and centripetal). The analysis of the nuclei shows that the morphology, texture and moduli of the blocks are particularly decisive for the debitage processes. The typological study indicates a strong presence of cortical or non-cortical flakes, of small dimensions, fairly wide and fairly thick, of nuclei and of blocks that were rarely used as strikers. The flakes present seem to characterise the objectives of the debitage. No typologically identifiable tools were found. Ceramics are attested by a few shards also collected on the surface. Elements related to food could also be approached by some remains of shells, probably oysters. In view of the objects present, this site can be attributed to the Late Stone Age.
