Xanthocon, Proustite and Jordanite crystals from the Lengenbach Quarry, Binntal, Valais, Switzerland – miniature specimen as unique piece
This miniature specimen from the Lengenbach quarry features a distinctive association of Xanthokon, Proustit and Jordanite arranged across a pale matrix. Subtle red tones, metallic grey areas and the characteristic textures of these rare sulfosalts create an appealing visual contrast. The piece originates from LB 2137 / 02 and reflects the typical attributes of the historic Lengenbach paragenesis.
Geology & Origin
The Lengenbach Quarry in the Binn Valley is renowned worldwide for its exceptional diversity of complex sulfosalts. Within the dolomitic host rock, low-temperature hydrothermal processes produced a remarkable variety of rare minerals that made this locality famous. Xanthokon, Proustit and Jordanite are classic representatives of this unique geochemical environment, highly valued by collectors and researchers alike.
