Parkerite and bismutohauchecornite in chromitites of the Urals: Example of the Uralian Emerald Mines

Resumo

An unusual ore mineralization represented by parkerite, millerite, bismutohauchecornite, bismuthinite, and nickeline was registered in altered chromitite from the Mariinsk emerald–beryllium deposit. Such mineralization is typical of Cu–Ni sulfide ores and hydrothermal veins from the five-element formation. This mineral assemblage was not registered in ophiolitic ultrabasic rocks and related chromitites. The find of bismutohauchecornite is the first in the Urals; the find of parkerite is the third.
