STRUCTURAL-MATERIAL COMPLEXES AS INDICATORS OF GEODYNAMIC SITUATIONS ON THE EXAMPLE OF THE EASTERN PART OF THE CENTRAL CAUCASUS

Abstract

Evaluation of selected geodynamic situations of Wilson cycle formed geodynamic one or other existing structural-material complex of core microplates and structural-tectonic zones of the Eastern segment of the Central Caucasus, carried out on the basis of the concept of lithospheric plates tectonics and related geodynamic regimes imposed on border and interior parts of tectonic plates subjected to various kinds of dynamic effects. Structural-material complexes are differentiated using geomorphological, tectonic, sedimentation, igneous bedrock, metamorphic and volcanic features. Describes the effects on the mantle crust vertical and (or) lateral thrust, which is determined by the dynamics of convective rising over current heated by outside core of mantle substrate and independent of convective currents jets from the lower and upper floors of the mantle - plums using the model of the two-deck tectonics of the lithosphere. Seismic tomography effectiveness allows using velocity propagation characteristics of elastic vibrations prepare models of the mantle density thermal inhomogeneities. As a generalization of the characteristics of each of the described structural-physical complex, describes the geodynamic situation.
