Analysis of obsidian cores of the late Holocene from central-west Santa Cruz province

| Sumario: | Cores allow studying the characteristics of raw material supply, the initial process of reduction and the production of blanks. In this way, we evaluate the use of black obsidian cores from Pampa del Asador in the central-western province of Santa Cruz during late Holocene. To this end, we develop a comparative analysis of the properties of obsidian cores recovered from the supply source of Pampa del Asador and from sectors located at different distances from it, such as Salitroso and Cardiel lake basins and Guitarra and Strobel plateau. We considered the degree and type of reduction of the cores taking into account variables such as frequencies, dimensions, types of cores and presence of cortex. Results show that distance does not explain the observed patterns. Thus, the strategies involved in the transport and exploitation of obsidian are discussed. |
