- Type
- Pre-Alpine Cu-As mineralisation in orthogneisses, with Alpine arsenite-bearing fissures
Centimetre-thick veins of fahlore (tennantite), quartz and mica in basement orthogneisses, with minor pyrite, chalcopyrite and molybdenite; Alpine fissures with rare arsenates and arsenites (cervandonite-(Ce), gasparite-(Ce), asbecasite, cafarsite) from remobilised tennantite. Fahlore ε205Tl (-3.0 and +0.1) within the range of porphyry copper deposits, consistent with a magmatic origin; possible arsenic source for Lengenbach, about 2 km to the north-east (Hettmann et al., 2014). Coordinates not given.
