Abstract
The pyrite specimens obtained from brown coal of the Mugun deposit have been studied by scanning electron microscopy (SEM) and X-ray fluorescence. Several pyrite generations have been identified. Pyrite of epigenetic origin has been found to prevail over other generations. Mineral inclusions of quartz and ilmenite and increased concentrations of Co, Ti and Sr have been found in the pyrite specimens studied. The presence of minerals and elements typical for igneous rocks may be indicative of the “Siberian traps” effect common in the deposit area on the conditions of peat accumulation.
