Geomorphological position of coarse clastic deposits of the Lower Miocene in wider area of the Bohutický les upland in the South Moravia and their relation to neotectonic landscape evolution
Roštínský, Pavel
The contribution deals with geomorphological aspects of the Lower Miocene gravel formations in the area of Bohutický les upland in contact zone between the Bohemian Massif (built up of solid basement rocks) and basin of the Carpathian Foredeep (filled with weakly consolidated Lower Miocene clastic sediments). In the top part and slopes of the upland, numerous denudational relicts of formerly more extended sedimentary covers are situated, originated due to differential neotectonic movements in the area during syn- and postsedimentary periods. Coarse fraction is commonly preserved which were the least prone to surface destruction. During detailed mapping, three main lithological components of gravels were distinguished, their areal distribution and relations to solid-rock forms of present-day topography were studied and their possible genetic processes were outlined. The acquired information, added with borehole data, were related to landscape evolution of the wider South Moravia area.

Geomorphological inventory of selected rock forms in the central part of protected landscape area Žďárské vrchy
Kirchner, Karel ; Roštínský, Pavel
The contribution presents results of the geomorphological inventory research in the central part of the Žďárské vrchy Protected Landscape Area. The geomorphological inventory was focused on the topography of 11 natural monuments in the geomorphological sub-unit Žďárské vrchy Hills among Nové Město na Moravě, Sněžné and Svratka. The contribution shows a methodological approach to geomorphological inventory and also characterizes basic relief features. Within the natural monuments, the geomorphological inventory was concentrated on rock forms, active and potential influencing of present geomorphological processes and human impact on the relief. The authors bring results of the geomorphological inventory on selected examples of natural monuments (the Drátenická skála rock, the Malínská skála rock, the Devět skal rock).
