Abstract
Un domo de obsidiana negra de composición riolítica aflora entre otras rocas volcánicas en la latitud 38.97716° sur y longitud 71.63528° oeste, en los Nevados de Sollipulli, al oeste del Volcán Sollipulli y al sur del pueblo de Melipeuco en el centro-sur de Chile. Se encuentran fragmentos trabajados de esta misma obsidiana en la superficie de varios sitios arqueológicos de la zona. Esta obsidiana es distinguible visual y químicamente de la obsidiana translúcida gris-verdosa derivada del Volcán Chaitén situado más al sur en la cadena Andina.
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.
