Panskyite, Pd9Ag2Pb2S4, a new platinum group mineral (PGM) from the Southern Kievey ore occurrence of the Fedorova-Pana layered intrusion, Kola Peninsula, Russia

Popis výsledku v původním jazyce

Panskyite, Pd9Ag2Pb2S4, is a new mineral (IMA2020–039) discovered in the platinum-group element mineralisation of the SouthernKievey ore occurrence of the Fedorova–Pana layered intrusion, Kola Peninsula, Russia. It forms tiny anhedral grains (of 0.5 to 10 micrometerin size) in the interstices of rock-forming silicates, often forming tiny inclusions in base-metal sulfides (millerite, chalcopyrite, borniteand chalcocite) and complex intergrowths with other platinum group minerals (zvyagintsevite, laflammeite, vysotskite, thalhammerite,unnamed phase Pd9Ag2(Tl,Pb)2S4 and others). In plane-polarised light, panskyite is creamy white with weak bireflectance, weak pleochroism and distinct anisotropy with brown to grey rotation tints; it exhibits no internal reflections. Reflectance values for panskyite in air(R1, R2 in percent) are: 43.8, 44.1 at 470 nm; 44.4, 44.7 at 546 nm; 45.6, 45.8 at 589 nm; and 47.2, 47.2 at 6 nm. Twelve electron-microprobeanalyses of panskyite gave an average composition: Pd 55.61, Ag 12.36, Pb 23., Fe 0.21, Ni 0.24 and S 7.17 total 99.09 wt.percent, corresponding to the formula (Pd9.05Fe0.07Ni0.07)sigma9.19Ag1.98Pb1.96S3.87 based on 17 atoms; the average of nine analyses on the synthetic analogue is: Pd 57.02, Ag 14.17, Pb 21.81 and S 7.44, total 100.44 wt.percent, corresponding to Pd9.07Ag2.22Pb1.78S3.93. The density, calculatedon the basis of the empirical formula, is 9.81 g/cm3. The mineral is tetragonal, space group I4/mmm, with a = 7.973(3), c = 9.139(3) angstroem,V = 581.0(4) angstroem3 and Z = 2. The crystal structure was solved from the single-crystal and powder X-ray diffraction data of syntheticPd9Ag2Pb2S4. Panskyite is isostructural with thalhammerite (Pd9Ag2Bi2S4). The mineral name is for the locality, the Pansky massif ofthe Fedorova–Pana layered intrusion in the Kola Peninsula, Russia.
