FERNANDEZ, María Victoria. Disponibilidad de materias primas líticas en los valles de los ríos Los Antiguos, Jeinemeni, Zeballos y Ghío (Santa Cruz, Argentina). Intersecciones antropol. [online]. 2015, vol.16, suppl.1, pp.61-73. ISSN 1850-373X.

The aim of this paper is to present the lithic raw material availability of an Andean range sector of N.W. Santa Cruz province that had no such characterization. It is a rich landscape in terms of its geology where secondary deposits have been generated by different geomorphological processes which have carried rocks throughout the area. The methodology for the study was formulated using geological and geomorphological information that was analyzed into a GIS. Surveys were conducted in most of the area, petrographic identification of nodules was performed and their quality, shape and size were analyzed to assess their potential for knapping. The results show a large variability of raw materials: some sectors are major focus of good quality rocks but of small sizes and others show the opposite pattern. There are nodules of suitable quality, shape and size for knapping, but only few of them meet these three qualities together and moreover their location is not limited to a particular feature of the landscape. This information, along with archaeological evidence, allowed us to discuss the role of lithic landscape in human rocks procurement strategies. As a result, it’s suggested an incidental exploitation of local resources and more frequent use of non-local rocks from nearby areas, with wide availability and excellent quality (e.g., obsidian, silicates).
