LUCERO, Gustavo; CASTRO, Silvina  and  CORTEGOSO, Valeria. Andean hunter-gatherers and herders lithic technology: change and continuities in the lithic resources exploitation during the Holocene in the NW San Juan. Rev. Mus. Antropol. [online]. 2017, vol.10, suppl.1, pp.65-74. ISSN 1852-060X.

This paper analyzes and compared aspects of technology organization in hunter-gatherers, transitional groups, and herders who occupied high-altitude environments in northwestern San Juan. We present meso-scale analyses of lithic sources, reductive sequences, artifact diversity, and material classes from three temporal segments of the Holocene. For the hunter-gatherers, the lithic analysis show expeditious and conservative strategies, predominance of local lithic sources, tool shaping and a low and high investment of labor. The record of groups with more diversified economies display a predominance of expeditious strategies with prevalence of local rocks, knapping designed to acquire blanks and less time investment in making lithic tools. Furthermore, there is an increased of undetermined lithic sources, more artifact diversity, less time investment in making lithic tools and more time investment in making lithic tools. We detected a continuity in hunting as an economic activity and sequential and regional lithic production systems that involve various tasks at three different altitudes.
