EBB46ASN5: Pyrite after Pyrrhotite with Galena and Sphalerite

A Pyrite crystal that has completely pseudomorphed an original Pyrrhotite crystal, preserving its pseudo-hexagonal structure. The specimen, consisting of a single large pseudomorphed Pyrrhotite crystal, is accompanied by black, lustrous, and twinned Sphalerite crystals, as well as cubic Galena crystals, one of which is cubo-octahedral with truncated vertices. A very elegant piece, from the Trepča mining complex, where lead, silver, and zinc are extracted.

EF86Z9: Pyrrhotite with Galena

Parallel aggregate of sharp thin tabular Pyrrhotite crystals with intergrown cubic Galena crystals. Despite the age of the sample, its excellent condition suggests it is very stable, probably due a partial substitution by Pyrite.
Herja Mine, Chiuzbaia, Baia Sprie, Maramures Romania (1960-1970)
Specimen size: 10.9 × 5.5 × 3.9 cm = 4.29” × 2.17” × 1.54”

Groups of laminar crystals of Pyrrhotite in rosettes. They are very aerial, of a considerable size and are on a rocky matrix. The crystals of Pyrrhotite, with recrystallized Pyrite on the surfaces of the pinacoidal faces, remain stable in spite of the long time that has passed since they were recovered, very probably due to the presence of the Pyrite.
