Chemical evolution of the earth
Abstract
Geochemical and cosmochemical processes that participated in the formation of the present chemical composition of the earth are discussed. Consideration is given to the role of radioactive isotopes in the formation of the earth's composition, the processes responsible for the origin of complex organic molecules, the differentiation of the earth mantle, and the origin of the first magmatic rocks, as well as to the chemical processes that took place during the evolution of the biosphere, the world ocean, and the atmosphere. Special attention is given to the use of modern methods of isotopic geochemistry and chemical thermodynamics in elucidating the evolution of metallogenic rocks.
