Vein bodies in the "Moroshkovoe lake" Target (Monchegorsk area) and related mineralization

The paper presents the results of petrographic and mineragenous studies of main rock and ores varieties of the "Moroshkovoe Lake" target (south-eastern part of the Monchepluton). It has been found that the area composed the massive norites and metanorites crossed by veins of two types: 1) with noritic composition; 2) with amphibole-plagioclase composition. The studies have found an association of different types of veins with different ore mineralization. Sulfide, oxide and PGE mineralization is associated with the vein bodies of the first type. The veins of the second type do not contain PGE mineralization: ore minerals are mostly chalcopyrite and to a lesser extent are represented by Pb and Zn sulfides.
