Аннотация: Karst rocks such as limestone, gypsum and salt are developed within vast areas of the Western Urals. Modern and ancient karst is widespread there. Perm region is situated in the Western Urals (Russia) and occupies an area of about 160,000 km2. The Paleozoic gypsums, anhydrites, salts, limestones, dolomites and more rarely the Proterozoic carbonate rocks occur in Perm region either at a low depth under the surface or crop out within an area of more than 30,000 km2 (Gorbunova et al. 1990). Three geological structures are present in this area: the eastern margin of the East European Platform, the CisUrals Foredeep and the folded zone of the Urals. Mainly sulphate karst and, to a lesser extent, carbonate karst occur on the Platform. Salt and gypsum karst develops in the Foredeep; whereas dolomite and limestone karst and somewhere marble karst are registered in the folded zone of the Urals. Karst rocks are covered by eluvial and deluvial deposits; in river valleys, they are overlapped by alluvial deposits or non-karstic rocks of a relatively small thickness. Seldom they are uncovered. The territory of the Western Urals in the whole and Perm region, in particular, undergoes strong technogenic impact, which alters significantly the conditions and factors of karst development due to irreversible transformation of relief and rocks, pollution of surface and groundwater, as well as vegetation degradation. Particular attention should be paid to the area of gypsum karst distribution.
