Budko and E. Kulagov.[2] It was officially named "talnakhite" in 1968.[3][4] 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 {{convert|80|°C|°F}} to {{convert|100|°C|°F}} it decomposes to tetragonal cubanite plus bornite.[5][6] References1. ^Talnakhite: Talnakhite mineral information and data {{sulfide-mineral-stub}}2. ^Ivetta Budko, Eduard Kulagov, "A Natural Cubic Chalcopyrite" (Будько И.А., Кулагов Э.А., "Природный кубический халькопирит"), Докл.
