Silcrete procurement system in Uruguayan prehistory

In this paper, thin-sections of archaeological materials from the early and middle levels (between ca 3.5 ky and ca 7.0 ky BP) from Los Indios site were also examined, as well as geological samples from potential quarries in the Departments of Soriano and Flores. Finally, the paper discusses the different strategies used to obtain and transport lithic raw materials from distant quarries in Central and Northwestern Uruguay to the Atlantic coast.
