摘要: The results of reinterpretation the geophysical data obtained during study central sector Kuril Island Arc (2005–2010) are reported. new boundaries shallow bedding basement and its block uplifts varied composition defined within previously discovered zone tectonic stretching destruction Vityaz submarine ridge interarc trough. Interblock depressions filled with sedimentary volcanogenic-sedimentary rocks distinguished. Areas represented by volcanoplutonic complexes including basic sialic series (up to granite) distinguished unbroken Ridge. Intrusions volcanic edifices composed registered on whole area studied. relationship between formation geodynamic processes in mantle is illustrated map Moho relief structural-density model Earth’s crust.
