Sources of obsidian artefacts, exchange networks and landscape use in Auca Mahuida (Neuquén, north‐western Patagonia)

Abstract: We present the results of XRF analysis for 59 obsidian samples from 11 archaeological sites in Auca Mahuida region, Northeastern Neuquén, Argentina. The results indicate that several obsidian sources were utilized; however, the intensities of their exploitation were variable.Strong differences appear between the Colorado river basin, characterised by a low variability of obsidian groups from northern Neuquén, the Auca volcano, with a low variability of obsidian groups but from local sources located north and s… Show more

“…The study of strontium isotopes as a proxy for spatial scales of human paleomobility is articulated with multiple lines of evidence in a biogeographic research framework that seeks to understand the movements of people, flow of material objects, and circulation of information across and along the rugged landscape of the Patagonian Andes. An ongoing macro‐regional program of geoarchaeological and geochemical characterization of Andean and extra‐Andean obsidian sources allows tracking lithic provisioning, use, and discard (Barberena, Fernández, et al, 2019; Fernández et al, 2017, 2019; Rindel et al, 2020). We are also conducting a large‐scale survey and morphological characterization of rock art in northern Neuquén Province, which suggests the existence of a sphere of exchange of information that ties distant areas (Barberena, Romero Villanueva, et al, 2017; Romero Villanueva, 2019; Romero Villanueva et al, 2020; see also Campbell et al, 2020; Martínez et al, 2017).…”

“…En este último punto, el caso más representativo es el del grupo químico Portada Covunco (PC1), cuya zona de dispersión nuclear se localiza en el centro este de Neuquén, Argentina. Este grupo está presente en sitios de cordillera, valles centrales y costa, incluso insulares, del centro sur de Chile (Campbell et al 2017;Pérez et al 2019;Stern 2018;Stern et al 2009). El mismo parece representar una selección cromática denominada variedad atigrada (Campbell et al 2017(Campbell et al , 2018Peñaloza et al 2019), una de las múltiples expresiones macroscópicas de tipo cromático del grupo químico PC1.…”

“…Caracteriza las áreas de distribución de los grupos químicos, estableciendo un rango de circulación de >300 km para las distintas fuentes primarias conocidas de la Patagonia y la Araucanía como una característica regional (Stern 2018). A este rango se agrega otro más restringido de 50 km para grupos químicos que se presentan en fuentes secundarias de la Patagonia noroccidental (Pérez 2010;Pérez et al 2019). Dentro de este, los sitios presentan desechos de talla con distintos porcentajes de corteza y evidencias de formatización de instrumentos de un mismo grupo químico.…”
