Based on the isotope-geochemical study of the fluid of gas-liquid inclusions, it is concluded that the evolution of the outer shells of the Earth, expressed globally, by a change in the gas composition of the atmosphere from the oxygen-free to oxygen-rich one at the boundary of the Archaean—Early Proterozoic, led to a change in the endogenous processes of ore and mineral formations.
