Marrite and Jordanite crystals from the Lengenbach Quarry, Binntal, Valais, Switzerland – micromount as unique piece
This micromount specimen with Marrit and Jordanite crystals from the Lengenbach Quarry, Binn Valley, Valais, Switzerland originates from the Lengenbach Research Group and carries the collection number L-20-9299. The specimen shows small dark crystals on a light colored carbonate matrix. The crystals occur on the surface of the matrix and represent a typical sulfide association from the Lengenbach deposit.
The combination of rare sulfosalt minerals together with the documented provenance from the Lengenbach Research Group makes this specimen particularly interesting for collectors of specialized alpine mineral assemblages.
Geology & Origin
The Lengenbach Quarry in the Binn Valley is world famous for its extraordinary diversity of rare sulfosalt minerals. Marrit and Jordanite belong to the complex lead arsenic sulfosalts that formed within the dolomitic host rock under very specific geochemical conditions. The deposit is known for its unique mineral formation and is considered one of the most important localities worldwide for rare sulfosalt species.
