Lithic raw materials in the northern coast of San Matias Gulf (Río Negro, Argentina): sources distribution and general trends in their exploitation
The northern coast of San Matías Gulf (Río Negro, Argentina) has secondary sources of lithic raw materials suitable for flake activities, which are almost ubiquitous in the environment. These rocks sets have been redeposited by marine, fluvial or glaciofluvial action. Also, they are of variable leng...

La costa norte del golfo San Matías (Río Negro, Argentina) presenta fuentes secundarias de materias primas líticas aptas para la talla, casi ubicuas en el ambiente. Estos conjuntos constituyen rocas redepositadas por acción marina, fluvial o glacifluvial, son de extensión variable y poseen litología diversa. En este trabajo se describen las fuentes a partir de la información de las cartas geológicas, de bibliografía específica, y de relevamientos propios. Además se analiza la influencia de las variaciones en la línea de costa en la disponibilidad y accesibilidad a las mismas, y se incluye la identificación petrográfica de las rocas. Finalmente, se delinean tendencias generales en su aprovechamiento. Los resultados indican que fueron las rocas silíceas las más utilizadas, seguidas de las vulcanitas y de las calcedonias en tercer lugar. Asimismo, se registraron diferencias en la explotación en los dos bloques temporales reconocidos para el uso de los recursos costeros en este litoral. Facultad de Filosofía y Humanidades.

| description |
The northern coast of San Matías Gulf (Río Negro, Argentina) has secondary sources of lithic raw materials suitable for flake activities, which are almost ubiquitous in the environment. These rocks sets have been redeposited by marine, fluvial or glaciofluvial action. Also, they are of variable length and possess diverse lithology. In this paper we describe the sources using information from geological maps, specific bibliography, and our surveys in the field. Furthermore, we examine the influence of variations in the coast line on the availability and accessibility to these sources, and include different rocks petrographic identification. Finally, we outline general trends in their use. The results indicate that siliceous rocks were the most exploited, followed by vulcanites and chalcedonies in third position. There were also differences in the rock exploitation in the two temporary blocks recognized for the coastal resources use in this coast. |
