Реферат:	eng: Based on a comprehensive study of hydrothermal magmatic systems at island arcs and a review of available mechanisms that cause elasto-plastic deformation in rocks, we considered the conditions for interaction between a convective magmatic cell and a convective hydrothermal cell in different rheologic zones of the crust. Three models have been developed to describe the generation of hydrothermal circulation systems: (1) the magma chamber is localized in a plastic zone, (2) partial and (3) complete penetration of the chamber into a brittle crust. It is shown that the last of these models is highly consistent with the structure of presentday high-temperature hydrothermal magmatic systems at depths greater than 1. 0-1. 5 km and with the structure of Miocene to Pliocene ore-bearing volcano-plutonic complexes that are eroded to different depths in different geologic blocks within these complexes. © 2012 Pleiades Publishing, Ltd.
