− | | Аннотация = In this study the finding of β-VO | + | | Аннотация = In this study the finding of pauflerite β-VO(SO <sub> 4 </sub>) in high-temperature outbursts of natural coal fire gases in the Kukhi-Malik tract near Ravat village, Fan-Yagnob coal deposit, Tajikistan, in brecciated siltstone is described. Pauflerite crystals are elongated-prismatic, measuring 40–100 microns; simple forms: b {010}, m {101} (most developed), e 110}, p {111}, δ {212}. Doubles are observed in (010) (?). The mineral is transparent, green, fragile. Glitter glass. Powflerite is optically biaxial, 2V close to 90º. The dispersion of the optical axes is very weak, v> r. The plane of the optical axes is perpendicular to the elongation of the crystals; <i>n<sub>p</sub> </i> = 1.733 (2), <i>n<sub>m</sub> </i> = 1.778 (3), <i> n <sub > g calc. </sub> </i> = 1.823 (4). Pleochroism: by Ng - green color, by Nm and Np - light green. Absorption scheme Ng> Nm> Np. Composition (cf. 3 ann., Electron probe data, wt.%): VO <sub> 2 </sub> 49.87, SO <sub> 3 </sub> 50.01, amount 99.88. The empirical formula is V <sub> 0.97 </sub> O (S <sub> 1.02 </sub> O <sub> 4 </sub>). The parameters of the rhombic unit cell (Ǻ): <i> a </i> = 7.392 (3), <i> b </i> = 6.272 (2), <i> c </i> = 7.064 (3). For the first time, a powder x-ray and drawings of powderedite crystals are shown. According to the presence of the mineral phases V, Cd, Mo, Tl, Bi, Sn, In, Sb, Se, Te, As, the sublimates of the coal fire at the Fan-Yagnobskoye deposit are close to the sublimates of the volcanic fumaroles of Kamchatka, Kuril, Italy, due to the common extraction mechanisms the gases of these elements from the host rocks, their transfer and deposition in the unloading zones. |
