Panskyite, Pd9Ag2Pb2S4, is a new mineral (IMA2020–039) discovered in the platinum-group element mineralisation of the Southern Kievey ore occurrence of the Fedorova–Pana layered intrusion, Kola Peninsula, Russia. It forms tiny anhedral grains (of 0.5 to 10 μm in size) in the interstices of rock-forming silicates, often forming tiny inclusions in base-metal sulfides (millerite, chalcopyrite, bornite and 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 %) 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 650 nm. Twelve electron-microprobe analyses of panskyite gave an average composition: Pd 55.61, Ag 12.36, Pb 23.50, Fe 0.21, Ni 0.24 and S 7.17 total 99.09 wt.%, corresponding to the formula (Pd9.05Fe0.07Ni0.07)Σ9.19Ag1.98Pb1.96S3.87 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.%, corresponding to Pd9.07Ag2.22Pb1.78S3.93. The density, calculated on 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) Å, V = 581.0(4) Å3 and Z = 2. The crystal structure was solved from the single-crystal and powder X-ray diffraction data of synthetic Pd9Ag2Pb2S4. Panskyite is isostructural with thalhammerite (Pd9Ag2Bi2S4). The mineral name is for the locality, the Pansky massif of the Fedorova–Pana layered intrusion in the Kola Peninsula, Russia.

Panskyite，Pd 9 Ag 2 Pb 2 S 4，是一种新矿物（IMA2020–039），是在俄罗斯科拉半岛Fedorova-Pana层状侵入体的南部Kievey矿石的铂族元素矿化中发现的。它在成岩硅酸盐的空隙中形成微小的反面晶粒（尺寸为0.5至10μm），通常在贱金属硫化物（镁铁矿，黄铜矿，斑铜矿和黄铜矿）中形成微小的夹杂物，并与其他铂族矿物复杂地共生（ zvyagintsevite，laflammeite，vysotskite，thalhammerite，未命名相Pd 9 Ag 2（Tl，Pb）2 S 4和别的）。在平面偏振光下，潘斯基石为乳白色，双折射弱，多色性弱，各向异性明显，具有棕色至灰色的旋转色泽。它没有内部反射。潘斯基石在空气中的反射率值（R 1，R 2以％计）为：43.8，470 nm下的44.1; 546 nm处为44.4、44.7；589 nm处的45.6、45.8; 在650nm处为47.2、47.2。对十二烷基磷灰石的十二个电子微探针分析得出平均组成：Pd 55.61，Ag 12.36，Pb 23.50，Fe 0.21，Ni 0.24和S 7.17总计99.09 wt。％，对应于式（Pd 9.05 Fe 0.07 Ni 0.07）Σ9.19银1.98铅1.96 S 3.87基于17个原子；合成类似物的九种分析的平均值为：Pd 57.02，Ag 14.17，Pb 21.81和S 7.44，合计100.44 wt。％，对应于Pd 9.07 Ag 2.22 Pb 1.78 S 3.93。根据经验公式计算出的密度为9.81g / cm 3。矿物是四方晶系，空间群我4 / MMM，用一个= 7.973（3），C ^ = 9.139（3）埃，V = 581.0（4）3和Ž = 2的晶体结构是从单解决合成Pd 9 Ag 2 Pb的晶体和粉末X射线衍射数据2秒4分。Panskyite与硫铁矿（Pd 9 Ag 2 Bi 2 S 4）是同构的。矿物名称是针对当地的，位于俄罗斯可乐半岛的Fedorova-Pana层状侵入岩的Pansky断层。
