Geological Influence on Stream Sediments Geochemistry from Precambrian Terrains of Uruguay.

Abstract The National Mining and Geology Directorate of Uruguay (DINAMIGE) recovered, in 2020, geochemical data of Uruguayan Precambrian terrains collected in the 80’s, involving 31,874 soil and stream sediment samples. These samples were analyzed for 22 elements (Ag, As, B, Ba, Be, Cd, Co, Cr, Cu,...
