Woodland Sites in Argentine Northwestern Patagonia: Las Cachañas. Advances on Geochemistry and Lithic Technology Organization

We present a first approach to the technology and use of raw materials at the site of Las Cachañas, in the interior of the northern Patagonian forest. During these first pottery occupations, the lithic technology shows the majority use of local raw materials, such as silicas and basalts of immediate availability, over others of excellent quality and nearby availability, such as obsidians, which is interpreted as the result of a stable settlement and its temporary prolongation in a context of colonization of the area.
