Paleogeography and neotectonics of Kaniv dislocations (Ukrainian Shield, Ukraine) in the Neogene-Quaternary period

Abstract

ABSTRACT This article studies methods and approaches to the reconstruction of geomorphogenesis and tectonegenesis of Kaniv dislocations (Ukrainian Crystalline Massif) during the Neogene-Quaternary period. The main patterns of relief formation and evolution of tectonic movements were established, and the nature of the influence of glacial processes on relief and structure formation was determined. On the basis of structural and morphometric analysis, the tectonic evolution of Kaniv dislocations was reconstructed at the latest and modern stages. A number of structural and morphometric models with the use of spatial GIS analysis were created. Maps of palaeo- and modern relief, reflecting the morphological features and evolution of this region, were constructed. On the basis of morphometric data, the main factors and stage of morphogenesis, direct and indirect connections between old and newest geological structures and forms of modern relief were established, and a number of local structures of diapiric origin were identified. Peculiarities of the geologo-geomorphological structure of Kaniv dislocations at each stage of their formation were determined. The proposed method can be used for reconstruction of tectogenesis and palaeogeographical events of other regions studied for the purpose of examining the influence of physical and geographical conditions and geological-geomorphological processes for biota development.
