Marinkin massif-platinum metals-nickel-copper locality at Middle Vitim mountain region, East Siberia
1 IntroductionMiddle Vitim mountain region is area of active ultramafic-mafic intrusion magmatism. Many massifs bear a ilmenite-titanomagnetite mineralization (Vitimkon, Kedrov, Yakut). Gold-bearing veins are mined at Irakinda and Kedrov gabbro intrusions. Ultramafic bodies contain the chromites (Shaman), asbestos (Molodezhnyi) and jade (Param). The sulphide PGE-Ni-Cu mineralization is known at the only Marinkin intrusion yet at the region.Marinkin dunite-troctolite-gabbro massif was mapped by G.A. Kibanov in 1961-1963 with positive recommendations for sulphide-nickel mineralization prospecting. The geological mapping at the scale 1:50 000 under the direction of V.S. Kosinov noted the disseminated sulphides at intrusion ultramafic rocks in 1964. E.L. Prudovskiy in 1968 studied the massif (Prudovskiy, Grudinin, 1972), dissected the sulphide Ni-Cu mineralization zones. M.I. Grudinin (1979), P.A. Balykin et al. (1983, 1986), E.G Konnikov (1986), A.E. Izokh et al. (1998), A.A. Tsygankov (2005) studied the petrology of the intrusion.
