Aprovisionamiento de sílex en el Prepirineo oriental durante el Paleolítico superior antiguo: El nivel arqueológico 497C de Cova Gran (Santa Linya, Lleida)

Abstract

The Sierras Marginales Catalanas (SMC) and the Eastern sector of the Ebro Basin have been surveyed with the aim of locating flint resources within this region. These resources have then been studied by petrographic (macro and microscopic characterization) and mineralogical (Xray Diffraction) methods. Results permit the scription of provenance of flint artifacts recovered in level 497C of Cova Gran de Santa Linya site. The preference for autochthonous materials (98,6% of Garumnian flint) and the finding of raw material stocks define an interesting system of lithic resources management for this unit of the Early Upper Paleolithic in the scope of Oriental Prepyrenees.
