The Pavlovské vrchy (Hills] are a part of the South Moravian Carpathians on the boundary between Czechoslovakia and Austria. The area studied is geologically a part of the Western Carpathians. It belongs to four geomorphological regions, such as: the Dyjsko-svratecký úval (Graben), the Dolnomoravský úval (Graben), the Mikulovská vrchovina (Highland) and the Ždánický les (Highland). The dissected relief of the Mikulovská vrchovina (Highland) - with the geomorphological dominant of South Moravia the limestone klippen of the Pavlovské vrchy (Hills) - and of the southwestern spurs of the Ždánický les (Highland) contrasts distinctly with the predominantly flat relief of the Dyjsko-svratecký úval (Graben) and the Dolnomoravský úval (Graben). The highest point of the area investigated is Děvín (550 m), the lowest point (161 m a. s. l.) occurs near the community of Bulhary. The basic features of the relief are conditioned on the one hand by lithology and tectonics, on the other hand by erosion-denudation development. These features developed in Neogene (after Badenian) and mainly in Pleistocene. The geomorphological investigations carried out especially during 1967 and 1968 paid special attention to the practical needs of water reclamation on the Dyje River. The main results of detailed geomorphological mapping were: 1. first establishment of the occurrence of cryopediments in the Czech Socialist Republic verified by sub-surface survey, 2. distinction of several Pleistocene terraces on the Dyje River and its tributaries, 3. establishment of the denudation chronology of the area investigated. The investigations supplied simultaneously sufficient data for a practical verification of the suitability of the project of the Unified Key to the Detailed Geomorphological Map of the World compiled by the working team of the Subcommission on Geomorphological Mapping at the IGU Commission on Applied Geomophology in 1968. The coloured detailed geomorphological map on the scale of 1:50,000 attached to this paper and the experience gathered during mapping show that the legend can be used for detailed geomorphological mapping.
