195:, the formation of tablelands involves a three stage process. First, the formation of a thick indurated surface layer duricrust by deep weathering beneath a relatively flat surface. Second, the breaching and incision of the duricrust layer by rivers or streams. Finally, the inward migration of valley walls and escarpments by slope erosion and denudation of mesas and buttes. An example of such tablelands is the laterite-capped Panchgani Tableland of India. Tablelands formed by the erosion of duricrusts are also quite common in parts of Australia and South America. In addition, the eruption of either
