LONG-LIVED STRUCTURAL ENSEMBLES OF THE EAST EUROPEAN PLATFORM. ARTICLE 3. TECTONICS OF THE PLATFORM’S COVER
Abstract
In the modern structure of the East European platform (EEP) an important role is played by long-lived dislocation zones, complicating the complexes of the platform’s cover and the basement. They are organized non-linearly, form a large vortex megastructure twisted clockwise, and are characterized by an inhomogeneous structure in the vertical and lateral directions. In the stages of their development, numerous dynamic (kinematic) inversions are observed, which are associated with the periodic manifestation and repetition of various geodynamic settings: collision, rifting, transpression and transtension. The processes of alternating rotation of EEP using “iris diaphragm” model explain many development laws of long-lived tectonic zones and vortex megastructure.
