LOYOLA, Rodrigo; NUNEZ, Lautaro; ASCHERO, Carlos  and  CARTAJENA, Isabel. LATE PLEISTOCENE LITHIC TECHNOLOGY AND THE COLONIZATION OF PUNTA NEGRA SALT FLAT (24,5º S), ATACAMA DESERT. Estud. atacam. [online]. 2017, n.55, pp.5-34.  Epub May 25, 2017. ISSN 0718-1043.

A first pulse of human occupation in the southern Atacama Desert (12.600 to 10.220 calyr BP) has been registered so far in two archaeological sites (SPN-1 and SPN-6) located at the rim of the Punta Negra Salt Lake (24,5° S,3.000 mas). Through the study of the lithic record, operational chains are reconstructed and technological strategies discussed. It is argued that during an initial stage ofhuman dispersalin an arid environment with sparse water resources, human groups developed aflexible lithic technology system, adapted to a residential mobility in large spatialscales. This idea is tested conside-ringfour main aspects 1) a low technicalinvestment in core reduction technologies, 2) ramified operational chains, 3) production of undifferentiated blanks 4) and systematic tool recycling and reworking

Keywords : Early peopling; Atacama Desert; operational chains; lithic technology.
