Abstract
The article presents new data on composition of the platinum group metals (PGM) mineralization of the Yuzhnosopchinsky-1 locality, in the massif of the same name. In the central part of the Kola Region this area is located in the zone of contact between two large layered mafic-ultramafic intrusions: Monchegorsky pluton and Monchetundra intrusion. There is the contact between fine-medium-grained metapyroxenites and coarse-grained metagabbronorites. At some distance from the contact, coarse-grained bodies of plagioclase-pyroxene and plagioclase-amphibole composition contain sulfide, oxide and PGM mineralization. Ore minerals in these vein-shaped bodies are represented mainly by the bornite-chalcopyrite-millerite group, in close spatial association with the magnetite-ilmenite group. Arsenides, tellurides and sulfides of palladium predominate among the PGM minerals.
