Description :
Doline Karst occurs in the upper catchments of the Tsondab, Gaub and Kuiseb rivers in the central Namib. The karst extends from the Escarpment foot westwards decreasing in density and altitude for 40 to 50 km. The existence of this well-developed karst is anomalous. The aridity and episodic torrential showers are not conducive to infiltration with attendant karst development. The impurity of the Namib Limestone, the chief karst host is similarly inhibitive. The existence of the karst arouses questions. The analysis yielded results that question assumptions that the limestone surface has undergone deformation and is multicyclic. It confirms the view that in the Namib there exist two limestones capable of hosting karst that are age and altitude distinct.
