Glacial Erosion on Karst

Abstract

The chapter presents the movement of warm-basedWarm-basedand cold-basedCold-basedglaciers. The factors influencing the slide and flow of glaciers are described. The geomorphic action of glaciers is discussed with a focus on karst. On karst, glacial erosionGlacial erosionis characteristic in karst depressionsKarst depressions, in stratified limestoneStratified limestone, as well as in troughsTroughswhich developed on similar rocks. As regards depressions, the denudation of slopes the inclination of which is identical with (downstream slopes) or opposite to (upstream slopes) the direction of glacier flow, the destruction of the thresholds of uvalasThresholds of uvalas(all of them) and the glacial erosional transformation of depressions partly filled with non-moving ice are analysed. The formation of stepped surfaces of stratified limestone terrains as well as the relationship between troughs with stepped surfaces, valley directions and the dip direction of beds are presented.
