Threshold and limit effects in karst geomorphology.
Abstract
Considering karst morphogenesis, there are no thresholds in the aqueous processes, but there are well-defined limits of mineral solubility. Because karst is rock specific and the other geomorphic systems are not, there is a situation of competition between karst processes and those of the zonal system. There is a threshold of effective competition which, if exceeded, results in other landforms or a polygenetic mix. Caves are the longest lived elements in our landscapes.-from Author
