The main goal of this research is the study of the strategies of provisioning and utilization of lithic raw materials within the Pali Aike volcanic field, Santa Cruz Province, Argentina (South America). The work includes an analysis of the land-use patterns and home ranges of the human populations that inhabited this region during the Late Holocene (ca. last 4000 years BP). The case-study presented here employs a methodology of lithic analysis that is regional and non-typological, which has the potential to be of value in other areas of the world and with other specific research goals.
