Resumen:
This work constitutes an initial approximation to the taphonomic study of surface lithic materials in the Arroyo Verde archaeological site, in the province of Río Negro, Argentina. The studied sector conforms a deflation surface, with the formation of a desert pavement, near the coastline and surrounded by stabilized dunes. The lithic registry is presented superficially with predominance of knapping debris. In order to perform a taphonomic characterization of the material sample, physical alteration profiles were constructed, which account for the action of various taphonomic agents, such as wind and the sedimentary load that it carries. In turn, the effects of other environmental disturbance agents, such as the presence of guanacos and the passage of vehicles as well as the distribution of the record in space, were evaluated. The obtained results indicate variability in the raw materialsused and in the stages of corrasion surveyed. The latter would suggest processes of differential deflation over time. Thus, this work forms a line of complementary evidence that contributes to the study of the site formation processes in the Río Negro coast.
