(Haagen-Bergbau, Webing, Abtenau, Salzburg, Österreich)
Gypsum mine, working a large gypsum-anhydrite deposit from several levels. Due to erosion and tectonic influences, the deposit is split up in a number of individual gypsum-anhydrite bodies, disseminated by clays, limestones and dolomites of the Gutenstein formation, Werfen slates and volcanic rocks, mainly metabasalts. In the different geological environments, several particular mineral associations were formed:
Pb-Zn-Cu mineralisation: On the lowest level of the mine, a lens of slate-like rocks was found included in massive gypsum. This lens was carrying pyrite and sphalerite, minor galena, marcasite, zincoan tennantite, covellite and fluorite and, very rarely, kesterite.
Zn-Fe mineralisations: Red sphalerite, associated with specularite, pyrite and dolomite is included in finely grained gypsum on the upper level.
Zn-Cu mineralisations: In the vicinity of Gutenstein dolomites, thin layers of finely cristallized sphalerite - probably of sedimentary origin - are included in anhydrite. Cavities in gypsum found in this environment also contain large sphalerite crystals, associated with enargite, pyrite, fluorite, hydrozincite, dolomite and magnesite.
Cu mineralisations: Copper minerals, mainly chalcopyrite and bornite, associated with pyrite, copper, cuprite, covellite, chalcocite and betekhtinite are sporadically included in the volcanic rocks. Some rare secondary minerals occur in contact zones to evaporites.
Located near Webing, about 6 km NW of Abtenau.
