摘要：

The Pb-, Zn-, barite- and Ag-bearing SEDEX deposits in the Graz Paleozoic (Eastern Alps, Austria) are hosted by polyphase deformed, greenschist facies metasediments and metavolcanics of upper Silurian to Lower Devonian stratigraphic age. The stratiform mineralization is characterized by pyrite, pyrrhotite, galena and sphalerite as the predominant sulphide phases, accompanied by chalcopyrite, arsenopyrite, freibergite, marcasite, pyrargyrite, tetradymite, cobaltite, ullmannite, breithauptite and others. Whole rock major and trace element data show metal enrichment in the adjacent host rocks. A detailed local geochemical survey to identify anomalies in stream sediments, in stream waters and headwaters reveals coincidence with former surveys, but also identified additional anomalies with elevated contents of Pb, Zn and Ba and in traces of Cu, Ni, As and Cd, which can be interpreted as indications of former unknown occurrences.
