The data on the mineralogical and petrographic composition of ore-bearing carbon metasomatites of the Middle Pridneprovie are given. In studying the composition of the gas component of the closed pores of carbon metasomatites revealed that the rock pores contain gases such as methane, hydrogen and nitrogen. The presence of mantle components in the composition of carbon confirms the profound nature of the metasomatic fluids, contributing to metasomatism. It was found that the contents of many elements are in direct dependence on the content of free carbon. A possibility of using carbon-metasomatic zones as indicators of dislocation metamorphism is established. The connection of carbon zones with occurrences of precious metals within the Middle Pridneprovie is shown.
