Abstract
General features of the basement tectonics of the East European platform (EEP) have been considered. The important role of the long-lived Paleoproterozoic tectonic zones has been noted. They were formed due to the cyclic processes of rifting and compression combined with the strike-sleep shearing. They include different structures often superimposed in space: systems of rifts and collisional orogenic belts, transtensional and transpressional zones, ensembles associated with tectonic-plate processes. A special role belongs to the non-linear structures: different scaled rotational structures, concentric and spiral shaped shears, the arcuate orocline belts and horizontal protrusions. Long-lived Proterozoic zones form a giant vortex structure twirled in a clockwise direction, the pole of which is located in the center of the Upper-Volga geodynamic node. The rotational processes of this giant structure can explain many tectonic features of the EEP development.
