“…Its presence in Pampean sites could be due to other factors, including human agency. As we and another authors have already expressed in previous papers (Berón et al 2012;Campbell et al 2017;Hajduk et al 2011;Mera et al 2015;Musaubach & Berón 2012;Salazar & Berón 2013), during Late Holocene the social networks increased and expanded along the bioceanic northpatagonic corridor. In this sense Campbell et al (2017), taking account of our proposals, states: "...the presence of obsidian at Mocha Island's archaeological sites is an exceptional situation within the context of the lithic universe that has been recovered there.…”

The mere occurrence of obsidian artifacts on Mocha Island lead us to interpret them as part of the more developed networks of communication that were becoming active around the end of the Early Ceramic period (1000 CE; 950 cal BP), connecting different areas of southern Chile with one another and the territory itself with areas on the other side of the Andean mountain range.…”

The goal of this study is to report the progress regarding the procurement and circulation of obsidian by hunter-gatherer populations during the Late Holocene in the province of La Pampa, Argentina. A total of 25 samples were analyzed in two stages; in the first stage neutron activation analysis (INAA) was used, while X-ray fluorescence (XRF) was employed in the second stage. This work adds nine archaeological samples from new sites and one from the Lihué Calel obsidian source. The results allow us to take into account the sourcing of the obsidian which was found in archeological sites of four areas of study located in the south and east of the province. Both, the results generated in this new stage, and those previously obtained are integrated and discussed in relation to the information produced by other researchers from the region, which are consistent with the existing ones for La Pampa. They indicate that the obsidian recovered was procured from sources located in the Argentinian and Chilean Andes, as well as the pre-cordillera in the provinces of Neuquén and Mendoza. New data expands the spatial perspective of our interpretations to four new research areas: Curacó basin, Lihué Calel hills, Valles Transversales (Transversal Valleys) and Bajos sin Salida (Endorheic low areas).

“…whereas Laguna del Maule 1-Laguna Negra should be considered "nonlocal" (Civalero & Franco, 2003;Gould, 1980;Meltzer, 1989). This macroregional geoarchaeological research program addressing an obsidian source-scape provides a foundation for integrating the archaeological record of different regions across northwestern Patagonia and southern Chile (Campbell et al, 2017;Méndez et al, 2018;Stern, Pereda, & Aguerre, 2012). Our short-term plans for future analyses include calibrating the geochemical results of distinct methods (PIXE-PIGME, LA-ICP-MS, XRF, and NAA) used since the 1990's (Durán et al, 2004;Giesso et al, 2011;Seelenfreund et al, 1996).…”

“…By generating the necessary geoarchaeological foundation (Glascock, ; Glascock, Braswell, & Cobean, ; Shackley, ), the ultimate goal of this study lies in reconstructing patterns of technological organization, human mobility, and social interaction in a highly heterogeneous Andean landscape, which includes yearlong potential for lowland habitation and limited seasonal availability of highlands and associated resources. In the section 4, we present a preliminary analysis of archaeological obsidians’ geochemical signatures from the Barrancas‐Buta Ranquil region (Figure ), recorded in the context of a program of systematic survey and excavation (Barberena et al, ).…”

Deconstructing a complex obsidian “source‐scape”: A geoarchaeological and geochemical approach in northwestern Patagonia

et al. 2018

Northwestern Patagonia is located in a tectonically active part of the southern Andes (Argentina), which has facilitated the formation of obsidian, including pyroclastic deposits that have been affected by geomorphic processes, resulting in a complex obsidian landscape. To date, the geomorphic relocation of obsidian in the landscape has not been a focus of systematic research, and this hampers our understanding of prehistoric human mobility. We present an updated assessment of the regional availability of different obsidian types based on results from our research program, which combines geoarchaeological survey and geochemical characterization to understand the properties and distribution of obsidian. This robust “source‐scape” provides the foundation for reconstructing patterns of lithic provisioning and discard. Our results suggest that interpretations of obsidian availability across the landscape should be more nuanced than is typically acknowledged. Based on our improved “source‐scape,” we discuss the patterns observed in an archaeological X‐ray fluorescence database. When compared with the geoarchaeological reconstruction of obsidian availability, the archaeological record conforms to a distance‐decay pattern. Contrary to previous interpretations, we suggest that the distribution of obsidian types is not isomorphic with human home ranges. This geoarchaeological research program provides a basis for integrating the archaeological record of different Andean regions.

“…En este contexto, es probable que la presencia de obsidiana refleje -junto con otros bienes foráneos-una sistematización en las vías de interacción. También para regiones trasandinas se ha puesto énfasis en que, hacia fines del Holoceno, el intercambio sistemático de obsidiana habría comenzado en algunas áreas como el centro-sur de Chile (Campbell et al 2017). Según estos autores, los aspectos estéticos inusuales del recurso y el aumento de la complejidad de las redes sociales desarrolladas en la región después de ca.…”

Se presentan resultados del análisis geoquímico (XRF) de N= 61 piezas de obsidiana correspondientes a diez sitios arqueológicos del norte de Mendoza (32°-33°S); un segmento latitudinal donde la cordillera de los Andes alcanza su máxima altitud. Además de estar fuera de la región andina con fuentes de obsidiana, los sitios se localizan al norte del límite de divergencia cultural establecida en los últimos milenios (34°S) entre sociedades productoras y cazadoras-recolectoras. Se evalúa la asignación de elementos de obsidiana a fuentes cordilleranas y extracordillernas entre (34°-37°S) todas en un rango comprendido entre 200 y 500 km de distancia. Las cronologías de los contextos abarcan un extenso rango temporal (entre ca. 7400 y 300 años AP) durante el cual se registra un proceso de diversificación económica que separa a las sociedades del área considerada de sus vecinas ubicadas al sur. Los resultados contribuyen a evaluar la dirección de interacciones que involucran principalmente la cordillera, pero además discutir cambios en escala y modalidad de acceso a las fuentes entre grupos con distintas estrategias económicas.
