ⓘ Bornite
Formula: Cu5FeS4
✪ Chalcanthite
Formula: CuSO4 · 5H2O
Description: Some of the chalcanthite from this mine is very unstable - dehydrating fast. Other samples are more stable. Nice crystals to a few mm, but always thin. Chalcantite are forming lager amsses and crust, sometimes also stalactites in the walls of the mine or on the flooor
ⓘ Chalcopyrite
Formula: CuFeS2
ⓘ Halotrichite
Formula: FeAl2(SO4)4 · 22H2O
ⓘ Malachite
Formula: Cu2(CO3)(OH)2
ⓘ Pyrite
Formula: FeS2
Habit: Combination of (210) and (111)
ⓘ Quartz
Formula: SiO2
