Abstract
Kaniv Dnieper area is a unique region that has evolved through the Neogene-Quaternary phase. The application of geological and geomorphological methods, remote sensing data and GIS made it possible to identify the genetic relationship between the processes of geomorphogenesis and tectogenesis within the Kaniv Dnieper region, to build a number of geological and geomorphological models. The methodology of structural-morphometric analysis is adapted to the GIS and the process of cartometric constructions is automated. An algorithm for creating order maps of valleys and basal surfaces has been developed. Basal surfaces are complex surfaces that combine local erosion bases and express the total movements of the earth’s crust over various time intervals. A study of the morphogenesis and tectogenesis of the territory of the Kaniv Dnieper region showed that the neotectonic movements within this region had a differentiated character. Five stages of tectonic evolution were determined during the Neogene-Quaternary stage of its development. Hypsometry of basic surfaces of five orders was investigated, and a detailed comparison of the morphology of single-order surfaces has been made. On the basis of the obtained data on the nature of the surfaces, absolute and relative elevations, the nature of the isobasite pattern, the geomorphological structure of each stage has been analyzed in detail. The conducted studies revealed a regular relationship between the relief and tectonics.
