Summary:Copper_nickel deposits hosted in unusual amphibole peridotites (cortlandites) are widespread along the eastern coast of Asia. The southern Sredinny Range ia situated approximately 130 km northwest of Petropavlovsk-Kamchatskii, Russia, and incorporates a group of copper_nickel sulphide prospects combined into the Dukuk_Kuvalorog_Kvinum ore cluster (about 500 km2 in area). The Kvinum-1 prospect is localized in the eastern Kvinum ore field in its middle reaches on the left bank of the Kvinum River. PGE mineralization is confined to the marginal zones of massive sulphide ores and to the zone of transition from amphibole peridotite to the overlying gabbroids. Palladium antimonides (sudburyite) and tellurobismuthides (michenerite) predominate over platinum arsenide (sperrylite). Native gold is related to ore intervals enriched in Ni, Pt, and Bi arsenides and tellurides. It is suggested that the concentration of the major sulphide minerals, as well as the PGM productivity of ore lodes, are controlled by the magmatic fractionation and sulphurization of derivatives of ultramafic magma under the influence of fluids. The fluids were accumulated at the front of the intrusions that provoked the layering of the primary magma. The PGM productivity appreciably increases with the enrichment of solution in Te, As, Sb, and Bi, which reveal chemical affinities with Pt and Pd. [A.M.C.]
