Abstract

The lithological and petrological properties of calcareous rock types are reflected by remarkably different structure, thickness and clast properties of frost shattered debris within the investigated Muschelkalk landscape as well as in chemical weathering rates within the debris. The AA. assume that the deposition of loess sediments might be sensitive to both properties and patterns of debris cover and to the amount of pre-existing "Braunlehm" that resulted from limestone dissolution processes. Soil moisture conditions and vegetation cover might have been as crucial factors for loess distribution as luff-/lee-effects of the regional wind system or karst surface morphology. Considering the ecological consequences implied by the structure and heterogeneity of periglacial loose rock cover, limestone landscapes in general seem to be vulnerable to degradation processes
