We have conducted our morphological researches on the loess-covered Tési plateau and on the basalt covered karst area around Mt. Kab in the southern part of the Bakony Mts. The nearly 600 m high basalt covered Mt. Kab emerges high from the undulating mountains and hilly areas of the Southern Bakony Mts. Its surface, an area about 35-40 km_ is covered by basaltic rocks of different thickness. Pseudokarstic landforms (depressions) developed on the basalt surface due to the karstic corrosion of the buried limestone layers. Grouping the objects of different morphology and evolution rate, and studying in corellation the genetic marks of the significant groups, a special karst process can be drawn, in which the depressions of various form can be understood as different stations of the same evolutionary series. The Mesosoic rocks building up the 60 km_ Tési plateau emerge to the surface rarely above the loess cover. There is agricultural activity on most part of the plateau. Typical covered karstic landforms developed on the 3-5 m thick loess cover. Subsidence dolines or alluvial streamsink dolines with a small catchment area were formed on the summits. We studied the processes, forms and occurrence of recent covered karst of Mt. Bakony, and these studies shows that on the covered karst surface of the Tési-plateau the recent pit formation along with baticapture connected to hidden and real rock boundary, as well as the opening and activation of paleokarstic passages developed before loess formation also play a role in the evolution of the covered karst surface forms of the Tési-plateau.
