Role of Strike-Slip Faulting of the Oceanic Lithosphere in the Formation of Pacific Volcanic Belts

摘要

The Pacific volcanic belts that extend over thousands of kilometers are formed on abyssal plates above the deep linear fault systems. Linearity is primarily typical of the deep strike-slip faults. The crucial role of strike-slip structural assemblages has been established in the evolution of the East Sikhote-Alin volcanoplu-tonic belt formed on the continental lithosphere. These facts were used as a basis for setting the following problem: study of the infrastructure of volcanic belts from the point of view of their possible development above the deep strike-slip faults in the lithosphere. The deciding role of reactivation of deep strike-slip faults of the oceanic lithosphere in formation of intra-oceanic volcanic belts has been established for the first time.
