Tectonic-geodynamical zoning of the Ural-Timan-Paleoasian segment of Eurasia
Abstract
Methodology of geological zoning of orogenic belts, adequate to mobilistic paradigma, should be in a natural way correspond to geodynamics conception, taking into consideration the positions of lithospheric plate tectonics. For this purpose the methodology of tectonic-geodynamical zoning is being suggested. The base of such zoning is the distinguishing of zones with associations of one-type geodynamical regimes and environments and their structural combinations during the formation on the crust of oceanic type and localization in interplate position or on the boundaries of tectonic plates as a result of horizontal dislocations with the accretion and collision process manifestation. In its turn at the continental type crust in stable regimes folded systems have been formed. On this basis the particularities of tectonic-geodynamic zoning of the Ural-Timan-Paleoasian segment of Eurasia have been considered, general scheme of its zoning has been given as an example of the suggested methodology usage. A segment can be considered as a genotype of orogenic belts, being formed at the expense of the plate-tectonic accretion of oceanic basin on the craton periphery.
