ACCESSORY MINERALS OF THE MAFIC-ULTRAMAFIC MASSIF GALMOENAN (KORYAKSKOYE UPLAND, KAMCHATKA)
A group of accessory ore minerals was discovered in rocks of the Galmoenan mafic-ultramafic massif (Koryakskoye Upland, Kamchatka, Russia), which is represented by native metals (iron, copper, zinc, silver), iron-nickel and cobalt-iron intermetallic compounds, sulfides (pentlandite, cobalt- pentlandite, pyrrhotite, sphalerite, heazlewoodite, millerite, shandite, pyrite, chalcopyrite, the phase Cu<sub>3</sub>S<sub>2</sub>), arsenides (maucherite, nickeline, orcelite, modderite) and some other minerals. Their chemical composition, crystal forms and paragenetic associations are described. Formation of these minerals is connected with the serpentinization process.
