Abstract

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/façonnage 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 Paraná Basaltic Plateau of southern Brazil.

巴西南部上乌拉圭河流域佩斯凯罗河谷卵石工具产业的首次评估
本文介绍了在位于巴西西南部乌拉圭河流域上游佩斯凯罗河岸的 SC-CHA-030 露天考古遗址进行的考古材料位置地形调查和石器工业技术研究的初步结果。我们分析了原材料的选择和异形/法孔工具(单面、双面和三面体)的制作,以及皮质和半皮质薄片的制作(遗物),这些薄片通过简单的修饰就变成了工具。从地质考古学的角度来看,这些材料的空间分布模式与山麓和冲积平原之间的地貌过渡有关。我们对技术行为和考古遗址形成的研究发现,原材料和成型卵石工具是巴西南部巴拉那玄武岩高原工业的一个重要方面。
