Структурно-морфометричний аналіз території Кременецьких гір (частина 1)

Abstract

The geomorphological structure and the morphometric features are characterized, the structural-morphometric constructions of the territory of the Kremenets Mountains are conducted and analyzed. The multi-order maps of the baseline and vertex surfaces, the residual relief, and the local erosion are created with the help of the software called AcrGis. The features of the geomorphological structure and the stage of the relief development are determined. Some regularities in the distribution of the morphometric indicators of the different parts of the Kremenets Mountains are revealed. Twelve morphometric different-genetic and different-order maps are constructed, and the surface of the top, baseline, residual and erosion relief are made and analyzed in accordance with the hypsometric and morphometric characteristics for this analysis. The method of the constructing of the map models for the structural and the morphometric analysis are presented. The comparison of vertices and bases of different order, as well as vertex – basal surfaces are analyzed, which allowed revealing the latest and modern movements of the earth's crust, the quantitative estimation of the amplitude of the vertical movements. The altitude differences in the characteristics of model comparisons are presented. The analysis and the comparison of the models allowed establishing the nature of the latest movements, the ratio of the denudation and the accumulation, the intensity of the erosion processes of the formation of the different stages of the investigated territory. The maps of the apex, basal, residual, erosion relief, which are created, serve as a basis for the comparison of the different top and base surfaces and the single-row top-base surfaces with the linear and the annular tectonic structures (the analysis of the latest tectonogenesis) in the future publications. Key words: basic surface, vertex surface, watershed, erosion network, residual relief, local erosion, morphometric analysis, digital terrain model, watercourses order, neotectonic movements, North-Podillia ledge.
