ESCOLA, Patricia S. Variabilidad en la explotación y distribución de obsidianas en la Puna Meridional argentina. Estud. atacam. [online]. 2004, n.28, pp. 9-24. ISSN 0718-1043.  doi: 10.4067/S0718-10432004002800003.

Geochemical characterization of two obsidian sources located in the Department of Antofagasta de la Sierra (Catamarca) is presented. This information is combined with results of provenance analysis (INAA) carried out on obsidian archaeological artifacts from 20 sites dated between 2200-600 BP and located in several ecological zones of Northwest Argentina. Considering that the circulation range for the two sources are different, this paper attempts to evaluate the differential nature of, procurement, consumption and exchange strategies for both these obsidian sources. We further analyzed the lithic assemblages recovered from one of the obsidian sources and from the Casa Chavez Montículos site
