dc.description | Se presentan los resultados de un nuevo análisis de elementos traza en 26
artefactos de 19 sitios arqueológicos de la costa de la provincia del
Chubut. Dieciocho sitios son del sector norte, entre las desembocaduras del
Arroyo Verde y del río Chubut y el último está situado al sur, en Cabo Dos
Bahías. Seis diferentes tipos de obsidiana fueron identificados; tres de
ellos de fuentes conocidas: los tipos T/SCI de la fuente de Telsen y SI de
la fuente Sacanana, ambas del centro-norte de la provincia del Chubut y el
tipo PDAI de la fuente de Pampa del Asador, en la provincia de Santa Cruz.
Los tipos de fuente desconocida son: CC? anteriormente determinado en un
sitio arqueológico de Cerro Castillo, margen suroeste de la Meseta de
Somuncurá; el tipo T/SCII, en principio considerado como subtipo de la
fuente de Telsen, pero según estos nuevos análisis pertenece a una fuente
distinta; y un tipo nuevo, MSI, cuya fuente estaría en la Meseta de
Somuncurá. La información aquí presentada indica que los seis diferentes
tipos de obsidiana llegaron a la costa central de Patagonia desde centros
de aprovisionamiento independientes y desde distancias variables entre 100
km y 800 km. | |
dc.description | The results of analyses of trace-elements in twenty-six samples of obsidian
from 19 archaeological sites along the Atlantic coast, between Golfo San
Matías Oeste (41°55´58.8´´S) and Cabo Dos Bahías (44°54´77.9´´S) are
presented as a contribution to studies of sources and distribution of
obsidian in archaeological sites in central Patagonia, specifically the
province of Chubut, Argentina. Six different types of obsidian occur in
this collection, three of which come from known obsidian sources. Four of
the samples are chemically similar to obsidian type T/SCI, which is derived
from near Sierra Negra (42°21’S – 66°36´W), northeast of the town of
Telsen, and is located between 100 and 235 km linear distance west of the
sites along the coast in which this obsidian occurs. Five of the samples
are chemically similar to obsidian type SI from the vicinity of Cerro
Guacho (42°28´60´´S – 68°32´93´´W) in the zone of Sacanana, and which is
found between 270 and 400 km linear distance west of the sites along the
coast in which this obsidian occurs. Finally, one sample from the site Cabo
Dos Bahías has chemical characteristics similar to type PDAI obsidian from
Pampa del Asador, in the Andean foothills of central-south Patagonia, Santa
Cruz Province. Another sample of obsidian from this same source had
previously been reported from a site near Puerto Madryn, along the coast of
Golfo Nuevo, 800 km from Pampa del Asador. Concerning the samples from
unknown sources, five samples are of an obsidian type which also occurs
commonly in sites on and west of the Meseta de Somuncurá. The source is
therefore believed to lie somewhere within the area of this Meseta. This
type of obsidian is tentatively called type MS1. Two samples are chemically
similar to obsidian type CCI? found at the archaeological site Cerro
Castillo on the western edge of Meseta de Somuncurá. Nine samples are
obsidian type T/SCII, previously believed to be from the same source near
Sierra Negra as type T/SCI. However, a new analysis of samples from this
area indicates that it is not the source of T/SCII, and the actual source
of this obsidian, which is both more abundant and more widely distributed
that type T/SCI, is unknown. The data indicate that different types of
obsidian reached the coast from a number of independent locations between
100 km and 800 km to the West and Southwest | |
