Rock volume exploitation analysis

Abstract

The present Symposium was proposed with the objective of knowing different ways of approaching the study of those technical criteria that influenced the volumetric exploitation of rocks by the hunter-gatherer societies of the past. This includes different moments in the operational chain, from the search for certain morphologies of nodules in the sources, the technical criteria used for the preparation and exploitation of the nuclei, the identification of the production objectives, their preparation and the maintenance of the instruments. . In this sense, the invitation to participate pointed to works that exceeded the analyzes carried out in the quarry-workshops, addressing this problem even from the final stages of instrument making and in sites distant hundreds of kilometers from the sources. The case studies presented far exceeded the original expectations of the Symposium, allowing to know how this topic is worked in places with temporal ranges of the Pleistocene-Holocene, middle and late Holocene. Particularly in this volume some of these works are exposed, where you can read the results of research carried out in very diverse contexts: an eaves located in the Tandilia mountains, an open-pit site in the Interserrrana area, residential camps in the south of the province of Buenos Aires, occupations in lake basins of the central-west of Santa Cruz and early sites in the Serranápolis region in Brazil.
