- Type
- Polymetallic Cu-Zn-Mo skarn
Large copper-zinc-molybdenum skarn around a porphyry intrusion, with endoskarn, exoskarn, hornfels and marbles. Molybdenites very heterogeneous in δ98Mo, sphalerites uniform in δ66Zn; the waste dumps host weathering experiments (see mine drainage). Indicative coordinates.
