Aeolian Material Migration in Transbaikalia (Asian Russia)

Water- and Boron-Rich Melt Inclusions in Quartz from the Malkhan Pegmatite, Transbaikalia, Russia

In this paper we show that the pegmatite-forming processes responsible for the formation of the Malkhan pegmatites started at magmatic temperatures around 720 °C. The primary melts or supercritical fluids were very waterand boron-rich (maximum values of about 10% (g/g) B2O3) and over the temperature interval from 720 to 600 °C formed a pseudobinary solvus, indicated by the coexistence of two ty...

Migration and Restructuring in Post-Soviet Russia

W hen Russia became independent in 1992, it inherited from the Soviet Union a spatial distribution of its population that was incompatible with its emerging market economy. Internally the largest migration stream has been out of the overpopulated Russian north and Far East toward central Russia. At other geographic scales, as a result of decades of Soviet labor policy, there were numerous citie...

Material erosion and migration in tokamaks

The issue of first wall and divertor target lifetime represents one of the greatest challenges facing the successful demonstration of integrated tokamak burning plasma operation, even in the case of the planned next step device, ITER, which will run at a relatively low duty cycle in comparison to future fusion power plants. Material erosion by continuous or transient plasma ion and neutral impa...
