Fuel shale is now one of the most popular among alternative sources of raw materials for industrial energy. The Bazhenov Shale contains large part of oil shales oil of Russia, containing both solid organic material (kerogen) and liquid light oil in low permeable clay reservoir. Pyrite is a constant component of breeds. The natural iron sulphides are pyrrhotite and pyrite, they often form in hydrothermal processes and are subjected to active transformation in exogenous conditions. Sulfur content in kerogen reaches 30% a large part of which is in composition of pyrite. Research included a laboratory modelling of thermocatalysis effect on a sample of kerogen of Bazhen formation. Thermal treatment was carried out in inert and oxidizing environments. According to M?ssbauer spectroscopy and the x-ray diffraction analysis data, it is discovered that as a result of thermobaric treatment the part of monomineral pyrite is turning into magnetic form ? magnetite. The most influential effects on thermal transformation of kerogen have iron mineral components, the composition of which varies according to natural or man-made hydrothermal impacts. The natural hydrothermal processes are contributing to geologically immediate formation of substances similar to oil. The conversion of pyrite to different iron-containing minerals, depending on the conditions of thermal treatment, allows for the intensification of the situ transformation of kerogen with the formation of synthetic oil.
