A new copper-iron sulfide: M38-8/62E-PDF

"A copper-iron sulfide mineral from Noril'sk, Western Siberia, discovered and described as cubic chalcopyrite by Bud'ko and Kulagov, is shown to be a discrete mineral entity and not to be confused with cubic chalcopyrite. The term cubic chalcopyrite does, in fact, refer to a valid phase, which is the face-centered cubic high-temperature polymorph of chalcopyrite. The new sulfide mineral tarnishes very rapidly in air, changing from the chalcopyrite color to hues of pink and brown, and eventually becoming iridescent. High-temperature X-ray diffraction, D.T.A., and quench experiments indicate that on heating to about 80° C the mineral breaks down to "tetragonal" cubanite and minor bornite. On slow cooling the original mineral is reformed. Since this new mineral closely resembles the qualitative descriptions for chalcopyrrhotite in the literature, attempts to find it in specimens from the type chalcopyrrhotite locality were made, but none was found"--Abstract, p. 910.
