ВОСТОЧНО-САХАЛИНСКАЯ ОСТРОВОДУЖНАЯ СИСТЕМА ОХОТОМОРСКОГО РЕГИОНА
The structural elements of the East-Sakhalin island arc system and also the Okhotsk Sea subduction suture and the same name microcontinent are characterized. The petrochemical peculiarities and geodynamic conditions of the formation of erupted rocks and and structural element of the system were determined. It is shown that the formation of accretion-collision complexes of Rymniksky, Terpen'evsky, and Shchmidtovsky terrains including the fragments of the island arc system occurred at the process of collision interaction of Okhotsk Sea microcontinent, Sheltingskaya and East-Sakhalin volcanic island arcs.
