The field of geochemistry involves study of the chemical composition of the Earth and other planets, chemical processes and reactions that govern the composition of rocks and soils, and the cycles of matter and energy that transport the Earth's chemical components in time and space, and their interaction with the hydrosphere and the atmosphere. The important fields of geochemistry in our university are: marine environmental geochemistry in marine environment, geochemistry in modern metallogenesis at the sea floor, ore deposit geochemistry, sedimentary geochemistry and geochemistry in sea floor rock.
