LITHIC ANALYSIS OF MIDDLE HOLOCENE OCCUPATIONS FROM HORNILLOS 2 (JUJUY, ARGENTINA): DISCUSSING THE TECHNOLOGY AND DISTRIBUTION Of "SAN MARTÍN" PROJECTILE POINTS. Chungará (Arica) [online]. 2012, vol.44, n.1, pp. 85-99. ISSN 0717-7356.  http://dx.doi.org/10.4067/S0717-73562012000100007.

The goal of this paper is to analyze the lithic artefacts from layer 3 of Hornillos 2, a rockshelter located at Susques (Jujuy, Argentina), which have been dated to the beginning of the Middle Holocene (7,760-7,430 BP). These include points of the "San Martín" type, rarely mentioned in Argentine archaeology, but with a broad distribution around the Salar de Atacama and other salt-lake margins in Northern Chile, as well as the upper drainage of the Loa River. Lithic analysis shows that the early Middle Holocene occupations of the site are short term, reflecting specialized activities and a technological organization related to logistical mobility. In this context, San Martín points had a long history involving multiple manufacture sequences.
