Abstract:
The paper is a geomorphological classification of pseudokarst forms in Czechoslovakia/Bohemien Massif and the Carpathians. In the author's opinion, forms occurring in non-carbonate rocks, are morphologically and often genetically analogous to the forms of karst relief, and are pseudokarst phenomena. They are divided according to their size into macroforms in sandstone morphostructures of the Bohemian Cretaceous Basin some types of rocky valleys, water-shed plains and ridges, forming rock cities in some places, mesoforms with six types of caves, sinkholes, rock perforations and several rock phenomena and microforms such as weather pits and niches, lapies, etc.. The most prominent pseudokarst phenomena have been formed in the sandstones of the Bohemian Cretaceous Basin whose relief may be considered "pseudokarst". They are also common in other sediments; in neovolcanic rocks and granitic rocks, as well as in other types of rocks. Pseudokarst forms are the product of geomorphological processes, especially weathering and denudation, block rock slides, erosion, suffosion, etc. Most of them have been developing in the recent mild humid climatic conditions.
