Orthocuproplatinum, Pt3Cu, a new mineral from the Lubero region, North Kivu, Democratic Republic of the Congo

Popis výsledku v původním jazyce

Orthocuproplatinum, Pt3Cu, is a newmineral from the Lubero region of North Kivu, Democratic Republic of the Congo. Themineral, which has a synthetic analogue, occurs as a 1.5-mm-long alluvial grain in a heavy-mineral concentrate, togetherwith the holotype specimen of kitagohaite, Pt7Cu. The grain of orthocuproplatinum has a rim of hongshiite, PtCu, andabundant inclusions of calcite. Opaque and metallic, orthocuproplatinum has a whitish colour in reflected light and slightlyperceptible anisotropy. The crystal structure of orthocuproplatinum is orthorhombic, space group Cmmm. Its unit-cellparameters: a = 7.681(1) angstroem; b = 5.4318(8) angstroem; c = 2.7502(4) angstroem; V = 114.74(3) angstroem3; Z = 2. The calculated density is17.866 g cm−3. The strongest diffraction lines are [d in angstroem(I)]: 2.337 (11), 2.236 (100), 2.217 (97), 1.932 (61), 1.920 (30),1.362 (36), 1.169 (24), 1.161 (23). The Vickers hardness is 243 kg mm−2 (VHN25), corresponding to a Mohs hardness of 4.The empirical formula of orthocuproplatinum, calculated from a mean value of 12 electron-probe microanalyses that gave12.9 wtpercent Cu and 87.3 wtpercent Pt, is Pt2.76Cu1.24 on the basis of 4 atoms.
