Abstract
The key role of asthenospheric diapirism in the origin of the diffusive boundary of isotopic reservoirs of the Indian and Pacific MORB types was shown on the basis of high-precision Pb data. In view of the fact that the described processes are not unique for the zones of convergence, they have to be considered in modeling the formation of the juvenile continental crust.
