BONNAT, Gustavo Federico  y  MAZZANTI, Diana Leonis. EXPEDITIVE TECHNOLOGICAL STRATEGY IN THE MANAGEMENT OF LITHIC RESOURCES DURING THE POSTGLACIAL. THE CASE OF CUEVA BURUCUYA (EAST TANDILIA, ARGENTINA). Comechingonia [online]. 2021, vol.25, n.2, pp.151-182. ISSN 1851-0027.

This paper presents and discusses the analysis of the lithic technology assemblage at the CuevaBurucuyá archaeological site(eastern Tandilia), dated at ca. 12.700 years cal. AP. The archaeological site was defined as a logistical field camp and the local orthoquarzites of Balcarce Formation (FBO) were the preferred used resource for lithic stone tools manufacture, while the other less common rocks, from different spatial scales, were used in a lower frequency. Furthermore, in other early archaeological sites from Pampa humid subregion, the use of lithic resources was oriented to other better-quality rocks for knapping tools and the FBO were less used or not at all. However, in the eastern sector of Tandilia, FBOis the most abundant local resource and there was evidence that they were used with varying intensity at the archaeological sites. This research provides data on the use of lithic resources in the humid Pampas subregion and focuses on the development of the expeditive technological procurement and use behavior in the case of FBO rocks.
