The role of volcanism in the development of the Japan, Okhotsk, and Philippine marginal seas

摘要: Newly obtained petrological and geochemical data on Late Mesozoic-Cenozoic volcanic complexes in the Japan, Okhotsk, Philippine marginal seas of Pacific Ocean made it possible to specify types characteristics various stages volcanism seas, trace evolutionary history processes, identify geodynamic environments which deep-sea basins were formed, as well distinguish inherent features evolution continent-ocean transition zone Central Asian sector Ocean. These imply that processes formed this region similar. Significant differences revealed between zones predetermined, first all, by different Earth’s crust was involved major tectonic-magmatic participated generation magmatic melts.
