Obsidian sources in the northern Patagonian reflect an early use (ca. 8000 years BP). Provenance studies conducted so far realize that obsidian sources located in the Andes and limited access to the summer is those that reflect most temporal continuous use and spatial dispersion. Unlike sources located in areas of plain, whose use is frequent in the last 1000 years BP and reflect local use. The objective of this presentation is to compare the results the technological studies of surface samples that have been sampled in the mountainous source ?Las Cargas? and the plain source ?El Peceño?. The results obtained from both sources show differences in procurement activities carried out and allow discuss models proposed for southern Mendoza.
