Abstract

Only the coarse igneous rocks from coal seams of Donets Basin have been studied. The object of the study were thin sections of rocks, and they were described under a polarized microscope. In addition, the paper presents some chemical analyzes of igneous rocks and their petrochemical recalculations in the systems of A. Zavaritskii and CIPW. According to the quantitative composition rocks are: acid (60%), medium (36%) and basic igneous rocks (4%). As a result, the following igneous rocks: garnet-granite, granite, grain – granite, quartz-diorite, diorite, quartz-porfir, diabaz. In the granite rock-forming mineraloami is quartz, as - feldspar: plagioclase and potassium feldspars. Accessory minerals: garnet, Tsirсon, magnetite. Secondary minerals muscovite, sericite, calcium, pyrites.
