Estimation of neotectogenesis factors of the Middle Dnieper region by structural-morphometric method

Abstract

SUMMARY The research involved methods of remote sensing of the Earth, structural-morphometric analysis and geoinformation systems on the basis of which the connection and direct dependence of neotectonic movements, structural forms and modern relief were established. The main three morphostructural complexes (Kiev, Obukhiv, Kaniv-Trakhtemyriv blocks) were identified and analyzed, each with its own dominant factor. On the basis of the obtained indicators of the total amplitudes of the oscillations of the elevation of the relief, the features of the neotectonic evolution of different morphostructures, which are subject to individual rhythms, are revealed, and indicates the general complication of the morphostructural appearance of the region. It is confirmed that the northern regions of the region had an active upward movement dynamics in the Neogene epoch, and the southern ones in the Quaternary period. In general, the amplitude of fluctuations in the elevation of the elevation of the right bank of the Middle Dnieper in the Neogene-Quaternary period in the northern part was 100 m, in the southern - 135 m. Obtained data on the dynamics of the region can serve as a basis for the estimation of erosion-denudation and landslide processes within the Middle Dnieper.
