| Sumario: | This article presents the results of the petrographic analysis conducted on 21 samples of lithic artifacts manufactured on several raw materials and recovered from the stratigraphic context in Arroyo Seco 2 site (Tres Arroyos locality, Buenos Aires province). Several radiocarbon dates place the human occupations from the final Pleistocene to the Late Holocene. Our studies indicate that the analyzed rocks come from different outcrops of the Humid Pampas subregion. These sources are both primary and secondary, and are located in various sectors of the Ventania and Tandilia hill ranges, the Claromecó basin (Interserrana area), and the Atlantic coast. Our data corroborate and deepen the knowledge about the lithological characteristics of the rocks used at the site, as well as the origin, selection, provisioning, and circulation trajectories of the rocks since the Late Pleistocene. |
