TECNOLOGÍA LÍTICA DEL PLEISTOCENO FINAL Y LA COLONIZACIÓN DEL SALAR DE PUNTA NEGRA (24,5o S), DESIERTO DE ATACAMA

Abstract

SPN-1y SPN-6 son dos contextos arqueológicos ubicados en el margen noreste del salar de Punta Negra (24,5° S, 3.000 msnm), que marcan un primer pulso de ocupación humana en la puna del Desierto de Atacama meridional (12.600-10.200 años cal.AP). A través del estudio del registro lítico, se reconstruyen las cadenas operativas de talla y se discuten las estrategias tecnológicas implementadas. Se plantea que, en un escenario de dispersión inicial a un paisaje árido, con recursos hídricos segmentados, los grupos humanos habrían desarrollado un sistema tecnológico lítico flexible, adaptado a una movilidad residencial en escalas espaciales amplias. Esta idea es contrastada en cuatro aspectos centrales: 1) el empleo de sistemas de desbaste de baja inversión técnica, 2) la existencia de cadenas operativas ramificadas, 3) una producción de soportes indiferenciados y 4) el retomado y reconfiguración sistemática de instrumentos.
