SARIO, Gisela; PAUTASSI, Eduardo  e  SALVATORE, Marcos. Quarry-workshop El Ranchito (Dpto, Ischilín, Córdoba). A first approach to characterize provenience sources and the analysis of lithic sets. Rev. Mus. Antropol. [online]. 2017, vol.10, suppl.1, pp.65-74. ISSN 1852-060X.

This paper aims at presenting a first approach to the characterization of outcrops and techno-typological analysis of lithic materials collected in a quarry-workshop, located in the archaeological site El Ranchito (Valle de Copacabana, District of Ischilín) in the northern province of Córdoba. During archaeological research in the valley, we found lithic raw material of high quality for carving, a siliceous rock from which arrowheads were identified, in addition toother stone tools. While its presence is low as compared with other lithic artifacts such as quartz, such material was found in most archaeological sites in the region. In El Ranchito, three sources of this material were identified, in which quarry-workshop areas were formed. These resulted from four surveys in which eight collection grids of lithic material were conducted in different areas. The surveys helped establish the natural availability of this raw material, through which samples were analyzed under microscope and identified as silcrete. We report the results from the analysis of the first collection unit, in which we found, mostly, ecofacts and debitage, and, to a lesser extent, cores and tools, allowing us to infer that tasks related to the removal of nodule cortex were performed.
