CHARLIN, JUDITH E. Lithic raw materials and landscape use in the upper Gallegos River: The case of Laguna Cóndor, (Estancia Glencross, Santa Cruz, Argentina). Magallania [online]. 2012, vol.40, n.1, pp.163-184. ISSN 0718-2244.

The analysis of stone tool from the surface of laguna Cóndor (Estancia Glencross, Santa Cruz, Argentina), located in the upper basin of the Gallegos river, in an area known as los Morros, is presented. The methodology applied, denominated Minimun Analitical Nodules Analysis (Larson y Kornfel 1997), has the advantage of grouping the artifacts and ecofacts by rock nodule, which is more useful than clustering them by class or type of lithic raw material. This method allows us to doing a major resolution analysis and a more detailed quantification. The results shown the predominance of nodules represen-ted by only one piece of debitage, in some cases in non-local raw materials, and by sets of debitage in immediately available lithic raw materials. According to the organization models proposed as framework to this methodology, the results point out, at frst, the resharpening of tools manufactured and discarded in another place and with a minor rate, in situ manufacture and maintenance of tools, removed of the site and transported far away. This pattern, together with other lines of evidences, suggests a logistic landscape use, at least in historic times, according to the available radiocarbon dating.

Palabras clave : morros; lithic raw materials; nodules; landscape use.
