Sulfide and noble metals mineralization in chromium ores of Lagorta-Kershor area, Voikar-Syninsky massif (Polar Urals)

Abstract

The results of study sulfide and noble metal mineralization in chrome ores of Lagortia-Kershor area, Voikar-Synya ultrabasic massif are given. Millerite, pentlandite, heazlewoodite, galena, arsenopyrite, cooper sulfides, mineral phases of osmium, ruthenium, iridium and palladium, native metals: gold, silver, zinc, copper, iron, nickel are identified and characterized. Formation of sulphide and noble metal mineralization (Au-Pd) occurred mainly in the Late Paleozoic time in connection with hydrothermal-metasomatic (metamorphic) processes. Gold-palladium mineralization superimposed not only on chrome ore, but also on host rocks in faults zones. Voikar-Synya and other ultrabasic massifs of Polar Urals deserve attention and further study of PGE and gold-PGE mineralization.
