Estudio tecno-económico de la industria lítica de Cerro Castillo (provincia de Última Esperanza, Chile)

Abstract

The present techno-economic study of lithic materials recovered in Cerro Castillo 1 site, provincia de Última Esperanza - Chile, delivers new precedents about the terrestrial hunter groups that lived in the area approximately 4.500 years BP. The set allows characterizing reduction schemes that emphasizetechnical systems based on the management of bifacial volumes in flake core production, which are then transformed by retouch in sidescrapers, endscrapers and other instruments. Other less represented operative chains are also recorded, as a blade project and the use of percussion over anvil methods. The weak presence of series orientated to the manufacture of bifacial artifacts or façonnage methods is emphasized.
