摘要

The results of studying isocubanite from sulfide ores of recent oceanic black smokers and sulfide mud of the Red Sea are compared with those of isocubanite from ores of the Noril'sk ore field and isocubanite synthesized in the course of experimental study of the Cu-Fe-S system. Isocubanite associated with chalcopyrite is enriched in Cu, whereas that associated with pyrrhotite or with pyrrhotite and haycockite is enriched in Fe. According to data in the literature, the CuFe_2S_3 compound has four polymorphous modifications: orthorhombic cubanite, tetragonal, hexagonal, and cubic isocubanite. Cubanite, and tetragonal and hexagonal modifications of the CuFe_2S_3 compound are high-pressure minerals. Therefore, they may be used as barometers.
