A new mechanism for the formation of ilmenite and magnetite series of granitoids in the Sikhote-Alin orogenic belt is proposed. The existing distribution zones of these magmatites are associated with the regional redox background, where magma crystallization occurs. The paper shows the relationship between the redox background in the lithosphere of the region and subduction processes in the Cretaceous-Paleogene time. The proposed mechanism of formation of the ilmenite and magnetite zones of Sikhote-Alin also explains the differences in redox conditions during the crystallization of Mesozoic magmatites in the orogens of the Eastern and Western Pacific coasts. |
