Resumen:
Obsidian was used by indigenous peoples of central Argentina and central Chile since the Early Holocene. Based on XRF and INAA analysis of more than 600 artifacts from archaeological sites we map the distribution of obsidian from three sources located in the Andean region and three sources from the eastern extra-Andean region, located between 33 and 37 degrees south. Using these data we interpret temporal changes that occurred in obsidian procurement and distribution. The results suggest a stronger use of the cordilleran sources over those locates in the lowlands, and the increase in the number of used sources through time. Data presented in this poster is related to another on geochemical characterization of obsidian sources.
