TURNES, Lucas et al. Primera aproximación al estudio de fuentes secundarias de materias primas (área intercuencas río Avilés - río Chico, Tierra del Fuego, Argentina). Intersecciones antropol. [online]. 2016, vol.17, suppl.2, pp.75-87. ISSN 1850-373X.

In this contribution the first results of a nonrandom sampling methodology applied on secondary lithic deposits are shown. Lithic sources are described quantitatively and qualitatively so as to know which raw materials were available for manufacturing stone artifacts in the archaeological site Herradura 1. This site is located in the northeastern of Tierra del Fuego and it was occupied by hunter-gatherers during the Late Holocene. In order to characterize and compare lithic secondary sources, analytical units where raw materials are present over the surface were selected. Several clasts attributes were analyzed, including geological origin, grain size, grain size homogeneity, presence of planar features and number of fractures. The results obtained confirm that although there are numerous secondary deposits immediately accessible, the knapping quality of available rocks is heterogeneous and the presence of unfavorable traits for knapping is frequently registered. In contrast, analysis of lithic artifacts recovered in H1 indicates a selection of raw materials of good quality: fine-grained rocks, with homogeneous size grain and a low percentage of fractures and planar features.
