The Cu south of the Brunndöbra and Schneckenstein range between absolute maximum (1910 mg/kg) deposits probably relate to the concealed Hainichen and minimum (0.2 mg/kg) is vast. Arithmetic Klingenthal-Kraslice Cu mineralis ation. In the central average and median are 28 mg/kg and 19 mg/kg, Erzgebirge, areas with Cu > 40 mg/kg accompany respectively. The average concentration in the deposits of Annaberg-Buchholz and Project supported by: metamorphic and sedimentary rocks is higher than Ehrenfriedersdorf. In the eastern Erzgebirge, zones in acid magmatites and in the Tharandt Volcanic of elevated Cu follow an alignment between Complex. Three main areas, each more than 2 km Freiberg and the Sn-deposits north of Altenberg , Freiberg in diametre, show Cu > 100 mg/kg: the central including the Sadisdorf greisen and vein d eposit Freiberg mining district; the western tip of the where mining of Sn, Pb, Cu and Ag is reported, as Dippoldiswalde Marienberg-Wolkenstein Ag/Pb/Zn deposit and the well as periods of Cu processing. NW of Sadisdorf , area between the Sn greisen of Gottesberg and the elevated Cu comes along with high Cd contents. uranium deposit of Schneckenstein. Levels of The lowest Cu concentrations (Cu < 4 mg/kg) occur Cu > 40 mg/kg characterize areas of Devonian in the western and northern parts of the Eibenstock sediments and volcanics along the western rim of Granite, in the Fichtelgebirge Granite area, and in the study area, the BiCoNi districts of Schneeberg areas of rhyolites and Neoproterozoic gneisses of and Johanngeorgenstadt, and parts of the the eastern Erzgebirge.
