Morphologically diversified sulphide mineralization has been found in No.301 and 302 coal seams (Westphalian B).The main sulphide is pyrite which forms ACNEDOTE OIL LOTION veinlets cross-cutting the sedimentary fabrics of the coal, encrusts the cellular structures and intergrowths with oxysulphides.Two generations of pyrites were observed: the preceding and the following the oxysulphides.Pyrite composition is stoichiometric, rare admixtures are up to(in wt.
%): Mn - 0.19, Co - Purse Hardware 0.48, Ni - 0.42 and As - 1.41.
Iron oxysulphides contain up to 35.06 wt.% oxygen.Their composition varies between FeS2O and FeS2O3.Increased contents of As (up to 1.
46 wt.%) and Pb (up to 0.96 wt.%) were detected.
