Abstract

The Oka plateau exists as a moderately elevated (2400 m) intermontane areabounded by the major East Sayan dome, the Main Sayan Fault, and the BaikalRift system, in the zone of the rift strike break. The plateau, which has a block structure, and its surroundings show specific features of recent geodynamics, including seismicity and distribution of Cenozoic basalts. Thesespecific features are related to the position of the region over a hotspotswell along 100 E, which corresponds to a column of low-density material connecting a sublithospheric asthenolith with the lower mantle.
