THE MAIN STRUCTURAL FEATURES OF THE SOUTHEAST OF THE EAST EUROPEAN PLATFORM
Yu.V. Kazantsev, T.T. Kazantseva
Abundant thrust-faults of various shape and spatial orientation have been distinguished within the territory of the southeastern part of the East European Platform. Their general distribution pattern has been revealed: arcuate features are characteristic of the central regions and linear features are found within the territory adjacent to the Urals. Tectonics of one type shows its evidences in a zone dominated by the other type tectonics. Such a penetration of structural features is typically for areas found at the junctions of zones showing different structure. An evident discordance between the horizon plans is due to both a widespread occurrence of some thrust dislocations, and several stages of thrusting processes. Such a situation is in agreement with tectonic periods distinguished in the Paleozoic evolution of the Urals and Peri-Urals regions adjacent to the platform, that had a direct impact on the platform evolution regime.
