Proceedings of the National Museum of Natural History, 2014, Nr 12, pages 3–11 Investigation of Modern Movements in Geosites of “Kaniv Dislocations” by utilizing GIS Tustanovskaya L., Grytsenko V. Summary:
Studies of the Kaniv dislocations started by Dubois de Montpereux (1832) and advanced significantly so that they have reached some hundreds publications. There are important sites that show significant have reached some hundreds publications. There are important sites that show significant all of those features are protected by Kaniv National Reserve authority. This unique area has outcrops of Mesozoic-Cenozoic rocks enriched in ancient fossil flora and fauna, as well as due to the tectonic position of the area. The purpose of this study is to determine the main objective of the current geological conditions of stadiality, to compare the leading structuring factors and the mechanisms of neotectogenesis in dislocations in Kaniv unique complex of Geosites. The investigations were provided by structural and morphometric analysis using GIS technology on eastern slope of the Ukrainian Shield. The structural and morphometric method was applied, the essence of which is in search of tectonic structures associated with tectonic movements of the Earth crust. This article shows the relationship of neotectonic movements, and quaternary structures that formed. For the analysis of trials geoinformation technologies (ArcGIS 9.3) were employed. The obtained model included surfaces of paleo- and modern landscapes of different genesis, based on structural and morphometric analysis. The data confirmed the most informative maps are those showing differences of basic surfaces between adjacent orders to quantify the amplitude of vertical movements and identify active local structures for the studied region. The amplitude of tectonic movements of the Earth crust from the Miocene until now has been demonstrated. The change of the local base level of erosion under the influence of the Dnieper River valley and glacial activity as factors for each stage of formation of the Kaniv dislocations has been tracked. Detailed evolution of diapiric structure under various condition of water escape and differentiation of tectonic forces was reconstructed at each stage. Field studies revealed and confirmed the presence of two types of diapiric folds — open and closed. The study of the past will help forecast erosion and sliding activities that endangers and negative impact on the ecological environment and development of agricultural in the area. This research can also serve for a detailed study of the interrelations of sediments and structures that form them belonging to different Quaternary age. Keywords:
