Resumen
Los trabajos arqueológicos llevados adelante en la costa del golfo San Matías (provincia de Río Negro, Argentina) han dado lugar a la identificación de fuentes potenciales de materias primas líticas ubicadas en diferentes geoformas del paisaje, a lo largo de toda el área. Estas fuentes son principalmente de tipo secundario ya que hasta el momento se han detectado cuatro fuentes primarias, ubicadas en la costa oeste, de las cuales solamente dos presentan evidencias de haber sido efectivamente utilizadas. En este trabajo se presentan las fuentes de materias primas, potenciales y efectivamente aprovechadas, localizadas hasta el momento, y se detallan sus características generales y su calidad para la talla. Por otro lado, se describen los resultados de la determinación de tipos de rocas a nivel macroscópico y a través de cortes delgados y su identificación en el microscopio petrográfico. Finalmente, se delinean brevemente tendencias acerca de la circulación de rocas (locales y no locales) en el espacio.
Archaeological investigations carried out in San Matías Gulf coast (Río Negro province, Argentina) have led to the identification of potential sources of lithic raw materials located in different landforms of the landscape along the entire area. These sources are mainly secondary; until now only four primary sources have been identified, located on the West coast of the Gulf, among which only two show evidence of human use. In this paper the potential and effectively exploited sources of raw materials that located until now are presented, and their particular characteristics and quality for flaking activities are detailed. Furthermore, the results of the determination of rock types at a macroscopic level and through thin sections and their identification using a petrographic microscope are described. The criteria used to assemble the reference lithotheque for the area are also presented. Finally, trends about circulation of rocks (local and non-local) in space are briefly outlined.
