Abstract

The derivation of the term "karst" is treated. Three main approaches to the definition of the one are considered: process, phenomenon and the region, where the karst phenomenon is manifested. It is noted that karst rocks occupies nearly 30% of continental area, during which the carbonate karst (in limestone and dolostones) prevails under evaporate karst (in gypsums, anhydrites and salts). The principal karst phenomena are viewed: on the surface (karren, dolines, uvalas, poljes and karst valleys) and underground: caves. Numerous classifications of the types of karst are discussed.
