Caracterización tecnológica lítica de Acevedo 1 (Chubut, Argentina)

Acevedo 1, located in Río Pico (Pico Valley, Chubut, Argentina), is an archaeological rock art site where human remains were recovered along with animal bones and a lithic assemblage. Diverse lines of evidence were studied there with the exception of the lithics. Therefore, in this work the focus is on the technological characterization of such artifact assemblage in order to determine how hunter-gatherers populations that occupied this valley have used this sector of Patagonia. The lithic assemblage is composed mainly of flaking debris, a retouched artifact and a core. The results show that the raw materials used are the same as in other archaeological sites from nearby localities along with allochthonous rocks such as obsidian of source(s) not yet determined. From our results it can be suggested that technological activities linked to the last stages of lithic reduction would have been carried out in Acevedo 1. These activities would be related to ephemeral residential occupations.
