Collection of scientific works . Novosibirsk: Nauka Publishing House, SO Institute of Geology and Geophysics 1974 152 p. The collection is devoted to the processes of endogenous mineral formation as a result of the activity of magmatic foci located in the lower parts of the earth's crust. On the example of a number of ore regions of Siberia and Central Asia, some physico-chemical features of the manifestation of metasomatic processes in the formation of subvolcanic hydrothermal deposits of the copper-molybdenum ore formation are considered. facial composition of hydrothermally modified rocks, multistage of their manifestation, source of thermal energy, aggregate state and composition of ore-forming solutions, as well as temperature and pressure during the formation of various stages and stages of mineral formation.
