摘要

本文介绍了Yuzhnosopchinsky-1地区同名地块中铂族金属（PGM）矿化成分的新数据。在科拉地区的中部，该区域位于两个大型层状镁铁质-超镁铁质侵入体之间的接触区：Monchegorsky深成岩体和Monchetundra侵入体。细粒-中粒变辉石岩和粗粒变辉长岩之间存在接触。在距离接触点一定距离处，斜长石-辉石和斜长石-角闪石组成的粗粒体含有硫化物、氧化物和PGM矿化。这些脉状矿体中的矿石矿物主要以斑铜矿-黄铜矿-磨石群为代表，与磁铁矿-钛铁矿群具有密切的空间联系。钯的砷化物、碲化物和硫化物在PGM矿物中占主导地位。

Platinum-metal mineralization of the Yuzhnosopchinsky-1 locality (Monchegorsk ore district, Kola peninsula)

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.
