At the stages of platform tectonic activation rock geomasses in riftogenic structures acquires the ability to horizontal displacement due to internal structural and material transformations under the influence of reid deformation in stress metamorphism zones. The article highlights the results of tectonophysical studies of post-rift complications of the architecture of the Dnieper-Donets paleorift. The structural manifestation of reid dynamic tectonics in the geological structure of the sedimentary complexes of the paleorift platform cover is strike-slip transformations of its primary linear elements — fault systems, tectonic segments, geoblocks, and anticlinal structure zones.Using the original method of reconstruction of tectonic stress and strain fields and tectonophysical analysis of geostructures, based on an analysis of anomalies of potential geophysical fields and vertical amplitudes of neotectonic movements, the territorial distribution, tectonic position and natural kinematic mechanisms of the formation of secondary deformation structures of tectonic flow, linear and areal concentration zones of reid deformations of subregional and zonal scales, size from hundreds of meters to tens of kilometers.The natural mechanisms of reid deformation are caused by horizontal-plane movements of structural elements, rocky ensembles of discontinuities and local structures of tectonic flow dynamically conjugated with them. The usual tectonic process of reid dynamic tectonics is the collision warping of the horizons of the sedimentary sequence, which causes deformation structure formation. Under its influence, structural waves of deformations of horizontal-plane tectonic flow were formed in the sedimentary cover of the paleorift, which determine the longitudinal tectonic segmentation of the geostructure and the main features of the system organization of the latest paleorift architecture.
