The Middle Paleocene–Early Eocene (60.5–53.0 Ma) Magmatic Stage in the Southern Russian Far East

The Sikhote-Alin orogenic belt is a key area for understanding the evolution of the lithospheric plate interaction in the East Asian paleocontinent margin. At the same time, only limited and fragmentary precision isotope–geochemical and geochronological data are available for this region. New age data on the Early Paleogene magmatism supplement the available material and substantiate a specific Middle Paleocene–Early Eocene magmatic stage (60.5–53.0 Ma) dominated by A-type acid rocks in the southern Russian Far East during the geodynamic reconstruction of the continental margin.
