DURAN, Víctor et al. Estudio de fuentes de aprovisionamiento y redes de distribución de obsidiana durante el Holoceno Tardío en el sur de Mendoza (Argentina). Estud. atacam. [online]. 2004, n.28, pp. 25-43. ISSN 0718-1043.  http://dx.doi.org/10.4067/S0718-10432004002800004.

Using trace elements analysis on obsidian samples we discuss the use of lithic resources and the mobility of the prehispanic population of southern Mendoza (Argentina) and of central Chile during the Late Holocene. As a result of this analysis and of regional systematic surveys we identified four new obsidian sources. A total of 70 artifacts from 20 archaeological sites dating to different moments of the Holocene were assigned to seven distinct sources, with changes in procurement and distribution through time. Results are discussed in the context of some of the regional mobility models proposed by several scholars
