Роль карста в преобразовании рельефа суши

Аннотация

Karst denudation value is estimated to be more than half of the total chemical denudation value and exceeds the mechanical one at many karsted plain regions. Apparent insignificance of karst for landforms transformation is due to the fact that the karst action proceeds not only at the surface but in the interior of a massif as well. The karst facilitates rocks desintegration by lessening their cohesion. The karst processes themselves produce at the surface various erosional and built-up landforms. Apart from this action they change conditions of relief formation thus influencing the relief indirectly. At mountain the karst may «conserve» remains of ancient relief levels. With view to their unification the karstic forms should be subdivided into nanoforms, microforms and mesoforms which correspond to nanorelief, microrelief and mesorelief categories.
