A dissected plateau is a plateau area that has been severely eroded, and 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 accompanying orogeny.
