Mineralogical features of chromitites of Lagortinsko-Kershorsky area in the Polar Urals

The material composition of chromitites of the Lagortinsko-Kershorsky area of the Polar Urals located in the northern part of Voykarosyninsky ultrabasic massif is studied. Ore bodies spatially are close to dunites of Rayiz-Voikarsky dunite-vehrlitehartzburgite complex. Chromspinellides are represented by chrompicotites. In chrompicotites there are inclusions of platinoids of osmium-iridium-ruthenium composition of laurite-erlikmanite series. In nickel sulphides micro-inclusions of minerals of palladium, represented by sobolevskite, potarite, zvyagintsevite and plyumbopalladinite are found. The Lagortinsko-Kershorsky area and other areas of Voikarosyninsky massif deserve attention not only in relation to chromites, but also to gold-platinoid mineralization which can be overlaid on chromitites, and on rocks.
