BARROS, María Paula. The choice of laminated supports throughout the Holocene in the Interserrana Bonaerense area (Argentina). Rev. Mus. Antropol. [online]. 2018, vol.11, n.1, pp.15-24. ISSN 1852-060X.

Abstract This article presents the results and discussion on the production of laminar technology on two broadly used raw materials from the Humid pampas: orthoquarzite from Grupo Sierras Bayas and ftanite. The data come from different archaeological sites of the Interserrana area; these contexts are dated to different periods of the Holocene. When compared with the extraction of wider and shorter flakes, the blades are usually represented with lower percentages. Nevertheless, it is important to study the circumstance sin which blade technology was selected, because this technology allows the obtaining of blanks with independent edges of different length; thus, a single artifact could have been used to develop different tasks. In this sense, one of the aims of this work is to determine the technical criteria that were considered for the preparation and exploitation of the cores. Finally, different variables, such as raw material, acquisition, and production objective, played a significant role at the moment of choosing this kind of extraction.

Keywords : Interserrana area; lithic technology; objectives of production; laminar technology.
