Epsomite / Hexahydrite or similar (?), Pyrite Kristalle frm the Lengenbach Quarry, Binntal, Valais, Switzerland – small cabinet specimen as unique piece
This small cabinet specimen from the Lengenbach Mine, Binn Valley, Valais, Switzerland consists of a broad plate of the characteristic dolomitic host rock of the deposit. Numerous small Pyrite crystals occur across the surface and stand out with their metallic luster against the lighter matrix. Parts of the specimen also show whitish to grayish mineral coatings that may consist of Epsomite, Hexahydrite or a similar sulfate mineral.
The specimen originates from the collection of the Forschungsgemeinschaft Lengenbach and carries the inventory number L-20-9303. It provides a representative example of the mineralogical environment of this famous locality and illustrates typical associated minerals within the dolomitic host rock.
Geology & Origin
The Lengenbach Quarry in the Binn Valley is one of the world’s most important localities for rare sulfosalt minerals. The mineralization occurs in Triassic dolomitic host rock and formed through complex hydrothermal processes. In addition to numerous rare sulfosalts, associated minerals such as Pyrite and various secondary sulfates may occur, the latter often forming through alteration and weathering processes.
