Abstract

Three new occurrences of Ge-bearing minerals have been recently recognized in the Cu-Ag Kupferschiefer deposit in Poland. These are Ge-enriched chalcopyrite from the epigenetic sulphide-calcite veins in the Polkowice-Sieroszowice mine, translucent sphalerite with up to 0.18 wt.% Ge in a sandstone-hosted calcite vein from Lubin mine and massive covellite-galena assemblage at the contact between Zechstein carbonates and Lower Anhydrite in GG1 shaft. Micro-beam X-ray fluorescence distribution maps allowed to recognize two types of germanium distribution in chalcopyrite: oscillatory zoning and a “dendrite-like” organization. Mineralization where argyrodite was found consists of massive covellite with galena, acanthite, jalpaite, sphalerite and pyrite suggesting high sulfidation state of hydrothermal fluids. All reported instances of Ge-enriched mineralization have a common feature. They are all related to local fractures, faults, shear zones or tectonic zones and suggest there might be a direct link between germanium enrichment and structurally-controlled mineralization in the Fore-Sudetic Homocline.
