De l'amont vers l'aval : fonction et gestion des productions lithiques dans les réseaux d'échanges du Chasséen méridional

Abstract : Between 4300 and 3500 BCE, the distribution of bedoulian flint in southern Chassey culture context reached a considerable scale. The flint blocks extracted from lower Cretaceous outcrops in northern Vaucluse was formed in specialized workshops situated near the deposits. It was then exported as unheated blades, but also as heated cores prepared to knap bladelets by pressure on consumer sites. The aim of this study is to understand better the organization of Chassey societies, distribution of networks from upstream to downstream, dealing with the question of enhancement of craft specializations which is one of the most important aspects. The productions are dealt with through networks, which is an original approach, because until now the studies have involved isolated sites or corpus of sites within a region. The study area is large, and therefore we have chosen to focus on the common specialized production, that is to say blades and bladelets of heated and unheated bedoulian flint, but also on other materials (Oligocene flint, Senonian flint, Los Monegros flint) in all sites. The corpus includes sites geographically positioned upstream to downstream of networks and have access to specialized productions: the only producer site which was the subject of a methodical excavation (Saint-Martin, Vaucluse), consumer sites (Les Moulins, Drôme, L’Héritière, Bouches-du-Rhône and Saint-Antoine, Hérault), a hypothetical central redistributor site (Auriac, Aude) and sites on the margins of the extension area of southern Chassey culture (St. Michel-du-Touch and Château-Percin, Haute-Garonne). Firstly, a methodology based on a traceological approach and materials science has enabled us to note that the heat treatment affects the stone fracturing and its path by changing the porosity and decreasing the tenacity. It could be shown, especially by edge acuity and mechanic tests or use of heated and unheated bladelets in a blind test, that the change in the properties of the stone results in an improvement in the sharpness of the blades. The functional analysis was then used to further our understanding of the role of specialized productions in the sous-systèmes techniques, that is to say, to understand how and for what purpose these tools were used. Lastly, the analysis was expanded into more general issues concerning the organization of exchange networks. These ideas are based on the level of integration of sites to different networks and lead to discussions on complementarity and operation of these networks.
