The use of quartz during the Upper Paleolithic and Early Mesolithic in Sabor valley (NW Iberia): The Foz do Medal case

In a regional perspective, it is possible to compare the quartz economy from occupations in Sabor valley to the ones from Côa valley, to the south, and discuss the role of rock crystal in Late Pleistocene inland human groups. It is clear that there was a technical ability to maximize a local lithic resource such as rock crystal which was exploited in order to achieve blanks similar to those obtained from flint cores.
