Environments

Plutonic igneous environments

Vysotskite occurs in andesine dolerite at the type locality, and in ultramafic layered intrusives elsewhere. It forms as disseminations that probably are crystallised products, at magmatic temperatures, of a residual immiscible sulphide melt (HOM). It is commonly associated with cooperite, and it is an ore of platinum group minerals (Mindat).

Localities

At the Hongshila Pt-Pd deposit, Boluonuo, Fengning County, Chengde, Hebei, China, vysotskite is associated with hongshiite, cooperite, sperrylite, isomertieite, magnetite, bornite, polydymite, diopside, actinolite and epidote (HOM).

At the type locality, the Severniy Mine, Talnakh Cu-Ni Deposit, Noril'sk, Putoran Plateau, Taimyr Peninsula, Taymyrskiy Autonomous Okrug, Krasnoyarsk Krai, Russia, vysotskite occurs mainly as minute irregular deposits, rarely as well-formed prismatic crystals up to 0.07 mm, in disseminated ores in andesine dolerite in the northern part of the deposit, associated with chalocopyrite, millerite (very rare elsewhere in the deposit), nickel-rich pyrite, linnaeite and cooperite. It was formed at a late stage (AM 48.708).

At the Stillwater Complex, Montana, USA, vysotskite is associated with pentlandite, pyrrhotite, chalcopyrite, cubanite, nickel-rich mackinawite, gold, braggite, cooperite, moncheite, isoferroplatinum, kotulskite, keithconnite and palladium-rich tulameenite (HOM).
