Approvisionnement en matériaux siliceux et économie du débitage dans le Sauveterrien : l’exemple du haut-plateau du Cansiglio (Alpes orientales italiennes) [Flint supply, local sources and exploitation in the Sauveterrian: a case from the Cansiglio high-plateau (eastern Italian Alps)]

In the eastern Italian Alps, circulation and exploitation of lithic raw materials beyond supply areas during Mesolithic has been the subject of punctual and limited studies in some sectors of this region until nowadays. Most information have been provided from the Dolomites, where economic strategies involved important and sometimes exclusive, exploitation of exogenous flint supplied in the southern Adige Basin and in the Venetian Pre-Alps. This strategy also involved complementary exploitation of local raw material with scarce quality and of exogenous hyaline quartz. In other sectors of the region, the production aims were completely satisfied by the local hyaline quartz. In the Venetian Pre-Alps, the discontinuous distribution in flint sources influenced similar activities in raw material importation and adaptation of the techno-economic systems to local sources. As study-case, the authors propose evidence from the Cansiglio plateau and discuss on the study conducted on the sauveterrian site Casera Davià II and on some preliminary observations regarding epigravettian and sauveterrian sites.
