Neotectonic evolution of the Žiarska kotlina Basin based on geomorphological analysis in the GIS = Neotektonický vývoj Žiarskej kotliny indikovaný geomorfologickou analýzou v prostredí GIS / Juraj Holec, Alžbeta Medveďová, Ladislav Vitovič, Roberta Prokešová. -- The Žiarska kotlina basin is one of the intramontane basins of the Western Carpathians. Geomorphological analysis of river terraces, thickness of Quaternary sediments, density of landslides and gullies, morpholineaments and faults was carried out using the Geographical Information Systems (GIS). The aim of the analysis was to understand the role of the neotectonics. The river terraces on the right bank of the River Hron are higher than those on the left bank showing the irregular neotectonic evolution of the area. The difference in height of the terraces on the left bank and right bank varies from 11 to 25 meters near Žiar nad Hronom and from 20 to 23 meters near Dolná Ždaňa. The interpolation of the Quaternary cover thickness shows three regions with a relatively thick quaternary cover, two of them in contact with the adjacent mountains and one along the alluvium of the Hron. The density of gullies on the right bank of the Hron is high. The density of landslides is biggest on the western margin of the basin. Analysis of the river terraces suggests that the Žiarska kotlina basin has not uniformly subsided, and the neotectonic activity is different in its individual parts.
