Description
Este trabajo presenta la información tecnológica producida a partir de un estudio distribucional a escala regional en el sector central del interfluvio de los ríos Gallegos y Chico (Campo Volcánico Pali Aike, Santa Cruz, Argentina) con el objetivo de caracterizar la señal arqueológica y sus posibles variaciones latitudinales a los O70°. A través del estudio de la organización tecnológica y la estructura tecnológica regional se discuten las estrategias de uso del espacio y los factores que pueden haberlas influenciado en esta franja del interfluvio. El uso humano de las lagunas en bajos sin salida es revisado especialmente. Se concluye que los cazadores-recolectores habrían ocupado con mayor intensidad aquellos espacios del interfluvio que conjugan la disponibilidad de rocas de grano fino oscuras tipo Potrok Aike en forma abundante con la menor distancia a los cursos fluviales.
This paper presents the technological information produced by a regional distributional study conducted within the central sector of the Gallegos and Chico Rivers Interfluve (Pali Aike Volcanic Field, Santa Cruz, Argentina). The goal of this regional survey was to characterize the archaeological signal and its possible latitudinal variations at W70°. By studying the organization of technology and the regional technological structure, we discuss land use strategies and the factors that may have influenced them within this portion of the interfluve. Human use of lagoons is especially targeted. We conclude that hunter-gatherers occupied more intensively those spaces that combine the abundant availability of dark fine-grained rocks of Potrok Aike type with the least distance to river courses.
