ZACCARINIITE, RhNiAs, A NEW PLATINUM-GROUP MINERAL SPECIES FROM LOMA PEGUERA, DOMINICAN REPUBLIC
Original language description
Zaccariniite, RhNiAs, is a new platinum-group mineral discovered in the Loma Peguera ophiolitic chromitite, Dominican Republic. The new mineral forms anhedral grains (1-20 ?m in size) and occurs intergrown with garutiite, in association with hexaferrum,Ru-Os-Ir-Fe alloys, Ru-Os-Ir-Fe oxygenated compounds, and chromite. Zaccariniite is opaque, has a metallic lustre and a grey streak. The mineral is brittle, with no cleavage. Values of VHN5 (10 indentations on different grains of synthetic RhNiAs) fall between 166 and 286 kg/mm2, with a mean value of 218 kg/mm2, corresponding to a Mohs hardness of approximately 3?-4. Under plane-polarized reflected light, the mineral is white with brownish to pinkish tints, has moderate to strong bireflectance, a strongwhite to pinkish brownish white pleochroism, and strong anisotropy, with rotation tints from orange to blue-green; it exhibits no internal reflections. Reflectance values of zaccariniite in air (R1, R2 in %) are: 49.4, 49.4 at 470 nm, 52
