Tectonics and stratigraphy| Резюме: | On the inversion stages of the evolution of intraplate geostructures, consolidated rocks acquire significant internal volumetric tectonic mobility due to structural and material transformations and deformations of the tectonic flow.Mechanisms and scales of structural alterations depend on the features of the geodynamics of the region, its original tectonic structure, the intensity of stress-metamorphic deformations of rocks, the nature of inversions of the regional and local fields of tectonic stresses.The article is devoted to the geotectonic study of structural complications of the collisional stages of tectogenesis in the architecture of the Precambrian foundation of the ancient geostructures of the Sarmatian plate-Dnieper-Donets paleorift (DDP). The territorial distribution and tectonic position of the secondary deformation structures of the tectonic flow of the sub-regional and zonal scales, in the size from first to tens of kilometers complicated by its riftogenic fault-block relief, is studied.Using the tectonophysics methods of research and analysis of the amplitudes of newest movements, it was established that under the influence of the mechanisms of steady tectonics, the structural waves of age-old deformations of the horizontal-plane tectonic flow were formed in the paleorift foundation. According to the results of the kinematic analysis of structural patterns of regional faults systems of the foundation, typical structural parageneses of the tectonic flow and in the composition of the zone deformation are diagnosed. It is shown that the steady tectonics has a regional manifestation as the main factor of the structural transformations of the foundation architecture at the collisional stages of the geodynamic evolution of the paleorift. |
