Monchetundraite, Pd2NiTe2, a new mineral from the Monchetundra layered intrusion, Kola Peninsula, Russia

Popis výsledku v původním jazyce

Monchetundraite, Pd2NiTe2 is a new mineral discovered in the the Monchetundra layered intrusion, Kola Peninsula, Russia. Itforms euhedral grains (up to about 20 micrometer) intergrown with kotulskite and pentlandite. Monchetundraite is brittle and has ametallic lustre. In plane-polarized light, monchetundraite is white to creamy pinkish white, strongly pleochroic and stronglyanisotropic on prismatic sections with rotations tints of pale blue, orange and olive green; it exhibits no internal reflections.Reflectance values (R1 nd R2) of monchetundraite in air are 44.3percent and 45.8percent at 470 nm; 48.7percent and 50.7percent at 546 nm; 51.4percentand 53.7percent at 589 nm, and 55.6percent and 57.5percent at 650 nm wavelength. Five electron probe micro-analyser (EPMA) measurementsof monchetundraite give a mean composition of Pd 40.04 wtpercent, Cu 0.72 wtpercent, Fe 0.27 wtpercent, Ni 10.58 wtpercent, S 0.64 wtpercent, Te48.20 wtpercent, total 100.07 wtpercent, which corresponds to the empirical formula (Pd1.96Cu0.06)sigma2.02(Ni0.94Fe0.03)sigma0.97 (Te1.97S0.04) sigma2.01based on a total of 5 atoms. Means of eleven EPMA analyses on the synthetic analogue are Pd 40.85 wtpercent, Ni 10.78 wtpercent, Te48.46 wtpercent, total 100.09 wtpercent, which corresponds to Pd2.03Ni0.97Te2.00. The mass density, calculated on the basis of the empiricalformula, is 9.45 g/cm3. The mineral is orthorhombic, space group Ibam, with a 6.31111(13), b 11.2469(2) angstroem, c 5.16687(15) angstroem, V366.75(1) angstroem3 and Z = 4. The crystal structure was solved and refined from the powder X-ray-diffraction data of syntheticPd2NiTe2. Monchetundraite adopts the crystal structure of synthetic Pd2NiTe2, which was first determined by Pocha et al.(2007) and refined in this study. The strongest lines in the X-ray powder diffraction pattern of synthetic Pd2NiTe2 [d in angstroem (I)(hkl)] are: 2.8117 (100) (040), 2.6190 (33) (211), 2.5835 (32) (002), 2.3000 (41) (141), 2.1874 (39) (231), 2.1189 (22) (150),2.0993 (22) (240), 1.9024 (52) (042), 1.8411 (26) (321), 1.3263 (32) (181). The mineral is named for the locality, theMonchetundra intrusion, Kola Peninsula, Russia.
