摘要
This article presents the first findings of a topographic survey plotting the location of archaeological material and of a technological study of the lithic industry at the SC-CHA-030 open-air archaeological site along the Pesqueiro riverbank, located in the upper course of the Uruguay River Basin in southwestern Brazil. We analyzed raw material selection and the production of shaped/faconnage tools (unifacial, bifacial, and trihedral) associated with the production (debitage) of cortical and semi-cortical flakes that were then transformed into tools by simple retouch. From the geoarchaeological point of view, the spatial distribution pattern of the material is meaningful in the context of the geomorphic transition between foothills and alluvial plain. Our study of technological behavior and the formation of archaeological sites finds that raw material and shaped pebble tools are a crucial aspect of the industries on the Parana Basaltic Plateau of southern Brazil. Este articulo presenta un estudio de los primeros hallazgos efectuados en el sitio arqueologico a cielo abierto SC-CHA-030, ubicado en la ribera del rio Pesqueiro (curso superior de la cuenca del rio Uruguay, suroeste de Brasil). Hemos realizado un levantamiento topografico (ubicando de manera precisa la procedencia del material arqueologico) y un estudio tecnologico de la industria litica, lo que nos ha permitido comprender mejor la seleccion de la materia prima, y la produccion de herramientas (faconnage unifacial, bifacial y trihedral) asociadas a la produccion (debitage) de lascas corticales y semicorticales, transformadas en herramientas por simples retoques. Desde el punto de vista geoarqueologico, observamos que el patron de distribucion espacial del material arqueologico es significativo en el contexto de transicion geomorfica: vertiente y llanura aluvial. Este trabajo presenta un nuevo estudio exhaustivo sobre el comportamiento tecnologico y la formacion de los sitios arqueologicos de la region, destacando que la materia prima y las herramientas talladas sobre cantos rodados son un aspecto crucial de las industrias liticas que se encuentran en la meseta volcanica del sur de Brasil.
