“…Measurement times were 60 seconds per sample. While other studies have employed longer measurement times (Craig et al 2007; Rademaker et al 2013), the XRF that we used had a sufficiently high count rate that permitted us to reduce the counting time to 60 seconds and still obtain reliable data. The XRF was calibrated for analysis of obsidian by using the University of Missouri Research Reactor (MURR) suite of 40 obsidian source specimens and their associated concentration data (Glascock and Ferguson 2012).…”

Campanayuq Rumi is a large civic-ceremonial center located in the south-central highlands of Peru. Founded in the late Initial Period (1100–800 BC), Campanayuq Rumi became an important center within the Chavín Interaction Sphere in the Early Horizon (ca. 800–400 BC). In particular, Campanayuq Rumi is significant because of its geographical proximity to Quispisisa, the most important and widely circulated obsidian source during the Early Horizon. Portable X-ray florescence (pXRF) was used to geochemically source a sample of 370 obsidian artifacts from Campanayuq Rumi. Though obsidian from Quispisisa dominates the assemblage throughout the site's history, diachronic analysis indicates that the diversity of obsidian sources increases markedly in the Campanayuq II Phase (700–450 BC). The pXRF data lead us to conclude that Campanayuq Rumi was the locus of obsidian distribution to other locations in highland and coastal Peru within the Chavín Interaction Sphere, and functioned as a regional center of worship and interaction.

“…Alternatively, people may have accessed to the exotic items through large-scale network of exchange or down-the-line trade. For obsidian found in late Pleistocene open camps of the southern Peruvian Pacific coast, which originated more than 130 km toward the Andes, it has been suggested that it was obtained through the exchange of processed fish within a regional network (Rademaker et al 2013;Reitz et al 2016). Exchange or down-the-line trade in intermediate territories is a feature assigned to well-established Holocene hunter-gatherers in South America (Dillehay 1999).…”

“…10,000 to 9000 cal yr BP (Pfeiffer et al 2018), it is likely that this obsidian point was brought before that time, roughly contemporaneous or slightly later than the occupation of QM12. Transportation of small quantities of obsidian from the high Andes was not rare at open camps in Pacific coastal region of southern Peru (Rademaker et al 2013), contemporaneous with QM12, which are thought to be part of exchange networks that included the circulation of processed fish (Reitz et al 2016).…”

From the Pacific to the Tropical Forests: Networks of Social Interaction in the Atacama Desert, Late in the Pleistocene

Chungara Revista de Antropología Chilena The social groups that initially inhabited the hyper arid core of the Atacama Desert of northern Chile during the late Pleistocene integrated a wide range of local, regional and supra regional goods and ideas for their social reproduction as suggested by the archaeological evidence contained in several open camps in Pampa del Tamarugal (PdT). Local resources for maintaining their everyday life, included stone raw material, wood, plant and animal fibers, game, and fresh water acquired within a radius of ∼30 km (ca. 1-2 days journey). At a regional scale, some goods were introduced from the Pacific coast (60-80 km to the west, ca. 3-4 days journey), including elongated rounded cobbles used as hammer stones in lithic production, and shells, especially from non-edible species of mollusks. From the Andes (ranging 80-150 km to the east, ca. 5-8 days of journey), they obtained camelid fiber, obsidian and a high-quality chalcedony, in addition to sharing knowledge on projectile point designs (Patapatane and Tuina type forms). Pieces of wood of a tropical forest tree species (Ceiba spp.) from the east Andean lowlands (600 km away, ca. 30 days of journey) were also brought to the PdT. While local goods were procured by the circulation of people within the PdT, the small number of foreign items would have been acquired through some sort of exchange networks that integrated dispersed local communities throughout several ecosystems. These networks may have been a key factor behind the success exhibited by these early huntergatherers in the hyper arid ecosystems of the Atacama Desert at the end of the Pleistocene. Different lines of archaeological evidence including open camps, workshop-quarries, lithic artifacts, archaeofaunal remains, plant and animal fibers and textiles, archaeobotanical remains, and paleoecological data show that people of the PdT managed a wide range of cultural items from the Pacific coast, the Andean highland and the tropical forest, that were integrated with resources

“…Terminal Pleistocene deposits in Sector II contain evidence of domestic structures. Obsidian recovered from the site originated in the Andean highlands some 130 to 150 km to the east (Rademaker et al, 2013). Vertebrate remains from Jaguay are so poorly preserved that otherwise durable drum (Sciaenidae) otoliths break Sandweiss et al (1989;see Sandweiss [2003]).…”
