On the «tropical» karst and some paleogeomorphological reconstructions

Abstract

The author develops a concept of residual (conical) karst to be a special morphogenetic type controlled by lithological and structural features and globally distributed. lt can develop within almost all the landscape zones and its morphology reflects zonal features. Within each zone are identified the generations of different age. Therefore from methodical point of view it would be inadequate to consider the residual karst as relict resulted only from tropical environment of ancient epochs. While searching for ore deposits the whole set of zonal landscape attributes should be considered. The author proposes to distinguish notions «zonal karst» (i. e. of moderate humid zone, of tropical zone, of arid zone etc.) from «residual (conical) karst».
