Talnakhite is a mineral of Chalcopyrite Group[1], also described as olivinic gabbro-dolerite[2] It was named after Talnakh ore deposit, a place by Norilsk in Western Siberia, Russia where it was discovered as reported in 1963 by I. Budko and E. Kulagov.[3] It was officially named "talnakhite" in 1968 [4][5] Despite the initial announcement it turned out to be not a face centered high-temperature polymorph of chalcopyrite, but to have composition Cu18(Fe, Ni)18S32. At 80-100 C it decomposes to tetragonal cubanite plus bornite. [6][7]
