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.

The basement’s top tectonics of the East European platform (EEP) has been considered on the basis of the modern mapping data. The importance of the long-lived tectonic zones that form the vortex megastructure has been justified.Their Riphean — early Vendian evolution was associated with activation of the Paleoproterozoic tectonic zones, which were transformed into paleorifts (aulacogens). The systems of the EEP aulacogens show the features of nonlinear structure and development: their evolution proceeded in the mode of transtension inside asymmetrically organized space between the active and passive paleocontinental margins; most of the paleorifts display wedge-shaped morphology, signs of asymmetric rifting and blocks rotation, a complex combination of elements of shear zones and gentle detachment zones tectonics, the vortex megastructure of the entire rifts system. Using an «iris diaphragm» model and the reconstructions with reversing plate rotation makes possible to explain the main patterns of the long-lived vortex structure of the EEP.
