| Abstract/Notes | Michitoshiite-(Cu) is a new Ge-containing platinum-group mineral discovered from the Haraigawa, Misato machi, Kumamoto Prefecture, Japan. It is named in honor of Michitoshi Miyahisa (1928–1983), a former professor of the Ehime University. Michitoshiite-(Cu) occurs mainly as the outermost layer of the nub consisting of cuprorhodsite in association with the isoferroplatinum-based grain. The grain of michitoshiite is anhedral shape up to 5 µm in size. It is opaque with a metallic luster and shows silver-gray color on the surface of nub. In reflected light, michitoshiite-(Cu) shows pale gray color with brownish tint. The Mohs hardness is 5 determined using synthetic compound. The density is 10.78 g/cm3 calculated from the empirical formulae and the unit cell volume. The empirical formula based on 2 apfu is (Rh0.95Pt0.03Ir0.01)Σ0.99[(Cu0.36Fe0.24)Σ0.60Ge0.41]Σ1.01, and the simplified formulae is Rh[(Cu,Fe),Ge]. Powder X-ray diffraction pattern was indexed as a cubic Pm3¯m (#221) with the lattice parameters a＝2.9771(11) Å and V＝26.39(3) Å3 (Z＝1). Based on the relationship between the composition and crystal structure by the synthetic experiment, michitoshiite-(Cu) is defined to be a mineral species with the composition of Rh(Cu1–xGex) 0＜x 侑 0.5 and the bcc-based structures. |
