Mineralization is restricted to one lithology of lithoclastic and oolitic wackestones and packstones. The ore minerals are sphalerite, galena, and minor iron sulfides. Three different styles of mineralization are present: sulfide brec

The most important ones occur between Mittersill and Zell am See and their geochemistry is described in this paper..Fine-grained clastic sediments locally contain thick doleritic sills and less abundant pillow lavas. These have been affected by hydrothermal alterati

Based on borehole data of secondary mineral distribution, four major alteration zones were distinguished: (1) uppermost low-grade zone (0–154 m), (2) silicified and argillized stockwork zone (154–300 m), (3) underlying propylitic transitio

A large number of ore and country rock samples were analyzed to obtain their sulfur isotope ratios and geochemical compositions including trace elements and REE distribution. Based on this data, a

The great majority of all base metal deposits in the East Pontides occupy the same stratigraphic position indicating a time- and strata-bound f
