Abstract

Theoretical ideas based on the results of numerical modeling of mantle convection are presented. The thermochemical model has taken into consideration such factors as two-layer structure of the mantle, formation of light substance in the D” layer (owing to transition of metallic components into the core), and heavy substances in subduction zones (eclogite-alteration of the oceanic crust). Numerical experiments have shown that this system allows phenomena of global mantle overturns, which make possible to model the general pattern of the Earth’s geologic evolution. The suggested theory establishes cause-effect relationships in the sequence of geological events and is conformed to all the empirical data.
