Murmansk Oblast (Kola Peninsula, northwest), Russia

Magmatic (Ni-Cu-PGE, carbonatites)Ni-Cu (PGE, Co)

Type: Ferropicrite-associated magmatic Ni-Cu sulfide (Palaeoproterozoic)

The second largest nickel-copper deposit in Russia after Norilsk. Mineralisation is associated with ferropicrite flows and intrusions about 2 Ga old, hosted in Proterozoic black shales. Five sulfide types are distinguished: disseminated, massive, breccia-matrix, chalcopyrite veins and sedimentary pyritic layers. The deposit has been mined since the Soviet era (1930s), today by Nornickel through Kola MMC.

δ34S in ‰ (per mil) Values of the same system

Standard : V-CDT

Value	Range	n	Mineral or matrix	Source
	−2 / 2 ‰		sulfides (West camp, primary Kaul and Kotselvaara ferropicrites) A symmetrical distribution, with a maximum between 0 and 0.5 ‰ and 97% of samples between -2 and +2 ‰: a pure mantle signature (0 ± 2 ‰, Ripley, 1999). A series of deposits (Kaul, Kotselvaara, Kammikivi, Sputnik-Verkhnee, Yuzhnoe) and the barren intrusions have a uniform δ34S of 1.0 to 2.5 ‰ (a juvenile sulfide source).

	1 / 7 ‰		sulfides (East camp, large Pilgujärvi and Kierdzhipori intrusions) The East camp is shifted to higher values, with a maximum between 4.0 and 4.5 ‰: contamination by crustal sulfur from the host black shales, acquired during magma ascent. Sm-Nd and S/Se studies confirm this addition of external sulfur.	Barnes et Melezhik 2001, Can. Mineral. 39:447-471
