Petrographic characterization of quartzite tools from the Palaeolithic site of San Teodoro cave (Sicily): Study on the provenance of lithic raw materials

Abstract

A petrographic characterization has been used here, for the first time, in the study of lithic raw materials exploited in prehistoric Sicily. Our research interests one of the oldest archaeological sites with evidence of the early human peopling of the island (∼15kyr ago): San Teodoro Cave, in northeastern Sicily. Two geological Formations, Numidian and Monte Soro Flysch gave origin to well-rounded pebbly quartzite elements scattered in the marine terraces surrounding the cave and likely exploited as one of the sources of the raw materials for the production of lithic tools by the Epigravettian communities having settled the place. The preference for one of the two qualities of quartzite is hypothesized thanks to the results of the petrographic analysis and a naked eye recognition of the differences between the two varieties of sandstone by the Epigravettian groups is also speculated.
