CORTEGOSO, Valeria; YEBRA, Lucía; CASTRO, Silvina y DURAN, Víctor. La presencia de obsidiana en contextos arqueológicos del norte de Mendoza: interacciones humanas en una región andina sin fuentes volcánicas. Intersecciones antropol. [online]. 2019, vol.20, n.2, pp.153-166. ISSN 1850-373X.
ARCHAEOLOGICAL OBSIDIAN IN NORTHERN MENDOZA: HUMAN INTERACTIONS IN AN ANDEAN REGION THAT LACKS VOLCANIC SOURCES. The results of geochemical analysis (XRF) of obsidian artifacts (n = 61) belonging to ten archaeological sites in northern Mendoza (32°-33°S) are presented. The sites are located outside of the Andean volcanic sources and to the north of the frontier (34°) established in recent millennia between farmers and hunter-gatherer societies. The assignation of obsidian artifacts to cordilleran and extra cordilleran sources (34° y 37°S) is evaluated, all of which are located between 200 and 500km from the study area. Archaeological contexts correspond to a chronological range of c.7400 to 300 years BP, during which period processes of economic diversification have been recorded that separated societies within the study area from their southern neighbors. The results contribute to the assessment of human interactions along the Andean cordillera, but also suggest changes in scale and modalities of access to sources among groups with different economic strategies.
