Dissected plateau Dissected plateau A dissected plateau is a plateau area that has been severely eroded so that the relief is sharp. Such an area may be referred to as mountainous, but dissected plateaus are distinguishable from orogenic mountain belts by the lack of folding, metamorphism, extensive faulting, or magmatic activity that accompanies orogeny. The Allegheny Plateau, the Cumberland Plateau, the Ozark Plateau, and the Catskill Mountains in the United States and the Blue Mountains in Australia and the Deccan Plateau in India are examples of dissected plateaus formed after regional uplift. These older uplifts have been eroded by creeks and rivers
Kerguelen Plateau fragments in the SKP, and these structures were eventually left behind as India moved northward. The ridge jump that made the Elan Bank a microcontinent occurred after 124 . The development of the Southern Kerguelen Plateau (SKP) 118–119 contributed to the oceanic anoxic event 1. Around 83.5 sea floor spreading between India and Antarctica was asymmetric in the Kerguelen Plateau region with two-thirds of the sea floor created being added to the Antarctic Plate. A ridge jump eventually transferred parts of the Kerguelen Plateau from the Indian Plate to the Antarctic Plate. The Kerguelen hotspot produced the long Ninety East
