THE MIDDLE PALEOCENE–EARLY EOCENE (60.5–53.0 MA) STAGE OF MAGMATISM IN THE SOUTH OF THE RUSSIAN FAR EAST

The Sikhote-Alin orogenic belt is a key area for understanding the evolution of the lithospheric plates’ interaction in the East Pacific margin. At the same time the precise isssotope-geochemical and geochronological data for the above said region are of a quite limited and scattered character. The new isotopic age data of the Early Paleogene magmatism are given which allow supplementing the current state of issue and establishing a specific Middle Paleocene–Early Eocene magmatic stage (60.5–53.0 Ma) in the south of the Russian Far East with the A-type acid magmatic rocks predominating during the geodynamic reconstruction of the continental margin.
