Copper in stream sediments

Copper (Cu) shows a log-normal distribution. 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 . In the eastern Erzgebirge, zones in acid magmatites and in the Tharandt Volcanic of elevated Cu follow an alignment between Freiberg Complex. Three main areas, each more than 2 km Freiberg and the Sn-deposits north of Altenberg , 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- 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 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 , and parts of the the eastern Erzgebirge.
