Typisation of karst topography

Abstract

The karst with naked surface of limestones is proved to result from degradation of the karst covered with vegetation. Within the limits of the latter besides sod cover loose deposits often can be found filling individual narrow wedge-like depressions. Covered karst is a type of karst topography which develops under loose mantle, the latter compensate for chemical erosion and determine formation of «karstogenous» aggradations surfaces. Buried karst is covered with thick series of younger deposits. «Armoured» karst develops under solid volcanic or unsalable sedimentary rocks within zone of erosional cuts influence. There are also some transitional types between those discussed above, as well as fluvial-karstic forms.
