Palladothallite, Pd3Tl, a new mineral from the Monchetundra layered intrusion, Kola Peninsula, Russia

Popis výsledku v původním jazyce

Palladothallite, Pd3Tl, is a new mineral discovered in the Monchetundra layered intrusion, Kola Peninsula, Russia.Palladothallite occurs in orthopyroxenite with disseminated Ni-Cu-Fe sulfides and in near-surface oxidized ore of anorthopyroxenite unit. In the holotype specimen, the new mineral forms anhedral grains about 1 to 20lm in size intergrown withbortnikovite (Pt4Cu3Zn). Palladothallite and bortnikovite form a rim around tulameenite (Pt2FeCu), Pt-Pd-Fe-Cu alloys, and Pt-Pd-Fe-Cu‘‘oxides’’in a goethite matrix. In plane-polarized light, palladothallite is white, anisotropy was not observed; itexhibits no internal reflections. Reflectance values of palladothallite in air (R’ inpercent) are: 53.9 at 470 nm, 57.1 at 546 nm, 59.4 at589 nm and 61.7 at 6 nm. Twelve electron-microprobe analyses of palladothallite gave an average composition (in wt.percent): Pd59.99, Cu 1.19, Fe 0.35, Ag 1.1, Tl 35.64, Se 0.34, and S 0.09, total 99.67, corresponding to the empirical formula(Pd2.894Cu0.096Fe0.032Ag0.053)P3.075(Tl0.895Se0.023S0.008)P0.926based on four atoms, with the ideal formula Pd3Tl. The density,calculated on the basis of the empirical formula, is 13.04 g/cm3. Palladothallite crystallizes with the same structure as syntheticPd3Tl, which was solved by Kurtzemann & Kohlmann (2010) from powder neutron diffraction data. Palladothallite istetragonal, space groupI4/mmm, witha4.10659(9),c15.3028(4) ̊A,V258.07(1) ̊A3, andZ¼4. Palladothallite crystallizes inthe ZrAl3structure type.
