| Sumario: | The aim of this paper is to analyse the abundance, techno-morphological characteristics and the exploitation of artifacts made from Fine-Grained Dark Rocks Potrok Aike type (RGFO PKA) of two surface samples recovered at different sector of southernmost part of the Patagonia. These assemblages were obtained from Laguna La Argentina, a secondary source of RGFO PKA located in the center of the Pali Aike volcanic field, and Laguna Cóndor, situated in the zone of the Morros (northwest of the Pali Aike volcanic field), where this raw material is not naturally available. The achieved results show variations in the exploitation of the PKA variety, which are related to the availability of this rock and the hunter-gatherer home range in theses spaces during the late Holocene. |
