Pyrite After Pyrrhotite with Calcite, Quartz & Boulangerite from Trepca Mine Complex, Kosovo
Pyrite after pyrrhotite, with boulangerite, quartz, and calcite, from Trepca Mine Complex, Mitrovica, Kosovo.
The calcite fluoresces orange with 365nm long wave UV light.
Pyrite after pyrrhotite (psuedomorph). This specimen has druzy pyrite replacing the original platy or sheet-like pyrrhotite crystals. The druzy pyrite sparkles brightly in any light.
Size: 76 x 48 x 35 mm. 168 grams.
Pyrite after pyrrhotite pseudomorph is a mineral specimen that shows the replacement of pyrrhotite by pyrite, preserving the original shape and structure of the former. Pyrrhotite is an iron sulfide mineral that often forms hexagonal or pentagonal crystals, sometimes resembling roses. Pyrite is another iron sulfide mineral that has a higher sulfur content and a cubic crystal system. Pyrite is more stable than pyrrhotite and can replace it through a chemical reaction, resulting in a pseudomorph.
