Caracterización de obsidianas arqueológicas del Macizo del Deseado (Santa Cruz, Argentina) mediante análisis por activación neutrónica
Open AccessDarío Hermo, Rita Plá et al.ARTICLERelaciones2025
In the archaeological contexts of the Deseado Massif (Santa Cruz, Argentina), obsidian artifacts are frequent, although the origin of this rock is not associated with local geological formations. Previous geochemical studies have identified Pampa del Asador (PDA) as the main source of obsidian in southern Patagonia. This article presents the geochemical characterization of 47 artifacts from archaeological contexts in rock shelters and open-air si…
Obsidian Technology and Transport Along the Archipelago of Southernmost South America (42–56° S)
Open AccessCésar Méndez, Flavia Morello et al.ARTICLEQuaternary2025
Obsidian was a key toolstone for the development of maritime lifeways in the western archipelago of southernmost South America. This area is a fragmented landscape where the major north–south movement of people along the Pacific was only possible by navigation because it is constrained by major biogeographic barriers. Two obsidian sources have been recorded, each one located on the extremes of the archipelago, and each has played a key role in th…

New results of obsidian artifact analysis from the middle and lower basin of the Salado stream, Río Negro province, Argentina
Open AccessJimena Alberti, M Cardillo et al.ARTICLEArchaeometry2024References: 14
The Salado and Verde streams constitute the two main seasonally available freshwater courses that flow into the Atlantic coast of the Río Negro province (continental Patagonia, Argentina, 42° South). This would have favored their use in the past as corridors for human circulation between the coast and the interior. This paper presents the results of the technomorphological and geochemical analyses of the obsidian artifacts recovered in the area t…

Las Quemas Rockshelter: Understanding Human Occupations of Andean Forests of Central Patagonia (Aisén, Chile), Southern South America
Open AccessCésar Méndez, Omar Reyes et al.ARTICLELatin American Antiquity2016Cited by: 9References: 33
Hunter-gatherer occupations of the forests of Patagonia are still not well understood compared to those of the open steppe and the coasts. The paucity of forest sites with a thorough chronological framework and the incomplete picture of climate-human dynamics in such environments pose a challenge to understanding the occupations of such habitats. This paper presents recent work at the Las Quemas rockshelter, an archaeological site located in the …

Secondary sources include river‐bed gravels within the valleys of Arroyo Cochicó Grande and Rí…
Hunter-gatherers, biogeographic barriers and the development of human settlement in Tierra del Fuego
Open AccessFlavia Morello, Luis Alberto Borrero et al.ARTICLEAntiquity2012Cited by: 15References: 12
Tierra del Fuego represents the southernmost limit of human settlement in the Americas. While people may have started to arrive there around 10 500 BP, when it was still connected to the mainland, the main wave of occupation occurred 5000 years later, by which time it had become an island. The co-existence in the area of maritime hunter-gatherers (in canoes) with previous terrestrial occupants pre-echoes the culturally distinctive groups encounte…
