Description
| - Lukkulaisvaaraite, Pd14Ag2Te9, is a new platinum-group mineral discovered in the Lukkulaisvaara intrusion, northern Russian Karelia, Russia. In polished section, the crystals are about 40 μm across, rimmed by tulameenite and accompanied to varying degrees by telargpalite and Bi-rich kotulskite. Lukkulaisvaaraite is brittle, has a metallic lustre and a grey streak. Values of VHN20 fall between 339 and 371 kg/mm2, with a mean value of 355 kg/mm2, corresponding to a Mohs hardness of approximately 4. In plane-polarized light, lukkulaisvaaraite is light grey with a brownish tinge, has strong bireflectance, light brownish grey to greyish brown pleochroism, and distinct to strong anisotropy; it exhibits no internal reflections. Reflectance values of lukkulaisvaaraite in air (R1,R2, in %) are: 40.9, 48.3 at 470 nm, 47.6, 56.4 at 546 nm, 52.1, 61.0 at 589 nm, and 57.5, 65.2 at 650 nm. Five electron-microprobe analyses of natural lukkulaisvaaraite gave an average composition: Pd 52.17, Ag 7.03, and Te 40.36, total 99.61 wt.%, corresponding to the empirical formula Pd14.05Ag1.88Te9.06 based on 25 atoms; the average of nine analyses on synthetic lukkulaisvaaraite is: Pd 52.13, Ag 7.31, and Te 40.58, total 100.02 wt.%, corresponding to Pd13.99Ag1.93Te9.08. The mineral is tetragonal, space group I4/m, with a 8.9599(6), c 11.822(1) Å, V 949.1(1) Å3 and Z = 2. The crystal structure was solved and refined from the powder X-ray-diffraction data of synthetic Pd14Ag2Te9. Lukkulaisvaaraite is a unique structure type and its crystal structure shows similarities to that of sopcheite (Ag4Pd3Te4) and palladseite (Pd17Se15). The mineral is named for the type locality, the Lukkulaisvaara intrusion in Russian Karelia.
