SALGAN, LAURA; GIL, ADOLFO  and  NEME, GUSTAVO. Obsidian inLa Payunia (south Mendoza, Argentina): spatial pattern and its implications in the regional alchaeological record. Magallania [online]. 2012, vol.40, n.1, pp.263-277. ISSN 0718-2244.  http://dx.doi.org/10.4067/S0718-22442012000100015.

This paper presents the results of technological analysis of obsidian artifacts from the Volcanic Field ofLa Payunia (south of Mendoza, Argentina). Previous studies in west central Argentina and central Chile discussed the role of obsidian sources in a regional large scale, interaction networks and human mobility in different scales. InLa Payunia two obsidian sources have been identifed and located in areas with different environmental characteristics and occupational history. Source El Peceño in the Nevado area and source Payún Matrú in El Payén area. We explore sourcing strategies and potential home-range in the south of Mendoza from middle and small spatial scales, and on the basis of technological studies of artifacts characterized by X-ray fuorescence (XRF), in the second half of the Late Holocene. The results suggest marked differences in the use of obsidian sources, as well as the extent and directionality of the exploited areas.

Keywords : obsidian; North Patagonia; procurement strategies; late Holocene; hunter gatherer.
