Svetlanaite, SnSe, a new mineral from the Ozernovskoe deposit, Kamchatka peninsula, Russia

Original language description

Svetlanaite, SnSe is a new mineral discovered from the high-sulfidation epithermal Au-deposit Ozernovskoe, Kamchatka peninsula, Russia. It forms tiny euhedral spindles (0.5-2 micrometer x 10-15 micrometer) in quartz, in close association with cassiterite, rutile, mohite, mawsonite, kiddcreekite, hemusite, tellurium, kostovite, Se-bearing fahlores (Se-goldfieldite – Se(Bi)-tetrahedrite – Se-tennantite). In plane-polarized light, svetlanaite is light-grey, pleochroic from white to cream and strongly anisotropic in shades of light blue, dark blue, khaki and orange-brown; it exhibits no internal reflections. Reflectance values of synthetic analogue of svetlanaite in air (R1, R2 in percent) are: 50.9, 56.5 at 470 nm, 50.2, 56.7 at 546 nm, 49.5, 55.3 at 589 nm and 48.7, 53.4 at 650 nm. Twelve electron-microprobe analyses of svetlanaite give an average composition: Sn 61.30, Se 37.22, and S 1.25 total 99.79 wt.percent, corresponding to the empirical formula Sn1.01(Se0.92S0.07) ∑0.99 based on 2 atoms; the average of seven analyses on its synthetic analogue is: Sn 59.98 and Se 39.71, total 99.59 wt.percent, corresponding to Sn1.00Se1.00. The density, calculated on the basis of the empirical formula, is 6.08 g/cm3. The mineral is orthorhombic, space group Pnma, with a 11.500(2), b 4.154(2) angstroem, c 4.445(2) angstroem, V 212.34(14) angstroem3 and Z = 4. The crystal structure was solved and refined from the powder X-ray-diffraction data of synthetic SnSe. It crystallizes in the GeS-structure type. It is isostructural with the mineral herzenbergite (SnS). The mineral name is in honor of Svetlana K. Smirnova, a Russian mineralogist, for her contributions to geology in the epithermal Au-Ag deposits of the Tien-Shan region.
