Pyrrhotite

specimen number:
2062464

location:
Nikolaevskiy Mine, Dal'negorsk, Primorskiy Kray, Russia

description:
A brilliant lustrous grouping of pseudo-hexagonal pyrrhotite crystals. In good condition, this is very fine for the species. From the 1990s.

The Nikolaevskiy Mine, located in the Dalnegorsk ore district of Primorskiy Kray, Russia, opened in 1982 and remains an active underground operation focused on polymetallic extraction. Geologically, the deposit is hosted within deformed Triassic-Jurassic limestone and skarn systems associated with Late Cretaceous volcanism. Hydrothermal activity formed extensive vugs and cavities within the carbonate rocks, creating ideal spaces for the crystallization of world-class sulfide and gangue mineral assemblages, including spectacular galena, sphalerite, pyrrhotite, pyrite, quartz, and fluorite.
