Department of Geochemistry

Video file

Department of Geochemistry is occupied with research of composition, structure and properties of rocks including coal and derivatives using methods of surface chemistry, geochemistry and petrology. There are studies in processes of origin and accumulation of organic substance in rocks and in characteristics of biological sources and palaeo- environment. Products of not perfect combustion in relation with contamination of the environment and problems of carbon dioxide as a greenhouse gas are studied.
