Le Premier Mésolithique du Centre-Ouest : modalités techniques de l’industrie lithique

摘要

Technological study of the lithic industries of the Early Mesolithic of the Centre-Ouest region of France indicates the use of local to regional siliceous materials. The aim of the knapping, carried out with a stone hammer, was to produce both bladelets and small long flakes. The reduction in technical investment is matched by optimization of the resulting production and is evident throughout the knapping operations : simplified shaping, maximisation of the invasion of the available surfaces then integration of the phases of maintenance in the knapping, the use of by-products as supports for common tools. The modalities can be listed : a unipolar semi-rotating sequence, sometimes followed by other sequences, often with the same characteristics, cutting through it. We perceive regional preferential choices, which do not seem to be determined by the raw materials or their availability, with a more intensive exploitation of the volumes for the Charente corpuses than for those of the Loire estuary. This division recalls a stylistic observation, made on the arrowheads, separating the zone near the Loire estuary from the Charente region.
