Mesozoic intrusive and volcanic rocks constitute major components of the geology of the Russian Far East. They have been mapped and studied in detail because of their associated mineralization, especially their gold deposits.
Modern U-Pb geochronology of zircons from granitic rocks is beginning to unravel the relative age relations between the various regions and belts of magmatism in the Russian Far East. Older K-Ar dating of these rocks had such a huge spread of ages that it was not possible to discern the space-time progression of magmatism that is now much better known across this region.
Most of the studies and data discussed here were carried out in collaboration with J.Wooden of the U.S. Geological Survey at the joint USGS-Stanford SHRIMP-RG facility.
The history of magmatism in the Russian Far East is intimately related to Pacific margin tectonics as well as to the opening history of the Arctic Ocean Basins. The exact timing of magmatism thus places important contraints on these plate motions through time.
