Petroarchaeology Hunter-gatherers Lithic raw materials Petroarqueología Cazadores-recolectores Materias primas líticas 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. En este trabajo se exponen los resultados obtenidos del análisis petrográfico realizado sobre 21 muestras de artefactos líticos confeccionados sobre diversas materias primas recuperadas en estratigrafía en el sitio Arroyo Seco 2 (partido de Tres Arroyos, provincia de Buenos Aires). Los fechados radiocarbónicos sitúan a las ocupaciones humanas desde el Pleistoceno final hasta el Holoceno tardío. Los estudios realizados señalan que las rocas analizadas provienen de distintos afloramientos primarios y secundarios de la subregión Pampa Húmeda, situados en diferentes sectores de las sierras de Ventana, Tandilia, en la cuenca de Claromecó (área Interserrana) y en los depósitos de la costa Atlántica. Estos datos sirvieron para corroborar y profundizar por un lado las características litológicas de las rocas explotadas en el sitio, y por otro lado las propuestas sobre el origen, selección, modos de aprovisionamiento y trayectorias de circulación llevadas a cabo por los grupos para la obtención de las distintas rocas desde el Pleistoceno tardío.
