Pyrite Pseudo after Marcasite with Dolomite
Nanisivik Mine, Nanisivik, Baffin Island
Nunavut Territory, Canada
8.7 x 6.1 x 4.8 CM (cabinet)
Golden, sharp and brilliant, Pyrites have fully replaced Marcasite crystals and these are well clustered on a series of large Dolomite crystals. Older specimen, ex John Marshall collection, obtained in 1991, there is no sign of instability or other problems as can happen with Pyrite pseudomorphs. A few crystals do have edge chips but most are perfect and complete. Attractive example with textbook twinned crystals from an very interesting, remote location.
