Lithochemistry of the Paleoisland-arc complexes in the orogenic belts of the Russian Far East

New chemical data on terrigenous rocks from the Russian Far East paleobasins different in age and geodynamic style were compared with similar data on the recent and old sediments accumulated in well-known geodynamic settings. The generalization and geodynamic interpretation of the original results revealed the island-arc nature of the studied objects and demonstrated the possibility of using the lithochemical approach, in combination with other geological data, for recognizing island-arc settings in fragments of paleobasins that represent structural elements of past orogenic belts.
