Abstract

STERN, CHARLES R; NAVARRO H, XIMENA; PINO N, JIMENA D  and  VEGA S.M., RODRIGO M.. NEW OBSIDIAN SOURCE IN THE ARAUCANÍA REGIÓN (SOUTH CENTRAL CHILE): CHEMICAL AND ARCHAEOLOGICAL CONTEXT OF THE BLACK RIOLITIC OBSIDIAN FROM THE NEVADOS DE SOLLIPULLI. Magallania [online]. 2008, vol.36, n.2, pp.185-193. ISSN 0718-2244.  http://dx.doi.org/10.4067/S0718-22442008000200014.

A dome of black rhyolite obsidian outcrops among other volcanic rocks at south latitude 38.97716° and west longitude 71.63528°, within the Nevados de Sollipulli, west of the Sollipulli volcano and south of the town of Melipeuco in south-central Chile. Worked fragments of this same obsidian are found at the surface in a number of archaeological sites in the área. This obsidian is both visually and chemically distinct from translucent grey-green derived from the Chaitén volcano further south in the Andean chain.

Keywords : Obsidian; rhyolite; south-central Chile; Sollipulli volcano.
