摘要：

The purpose of this work is to study geochemical features in the contact zone of gypsum - carbonate deposits by the electron paramagnetic resonance (EPR) method on the example of the typical core samples Syukeevskogo field. Choosing the annealing temperature of 350, 600 and 950 C-0 is associated with decomposition of organic matter and carbonates. Five different kind contact zones of gypsum-carbonate strata Syukeevskogo field along the borehole were selected. Quantitative changes of the EPR parameters: Mn2+, Fe3+, Cr3+, alpha and radicals caused by thermochemical effects on the rock and organic matter are presented in the diagram forms. Geochemical features installed in the contact zones such as a manganese increase in the newly formed calcite, a decrease alpha in sample oil-saturated, a reason of calcium excess or magnesium deficiency at increase alpha are discussed.
