Himalayan orogenic belt An orogenic belt interpreted as being the result of the convergence and collision of India with Asia. Because of variable uplift, great relief, high rates of erosion and upthrusts of midcrust, most depths within the orogen are exposed, down to the mid-crust, and the belt is thought to illustrate the later stages of the Wilson cycle. To the north of the Indus suture the Tibetan Plateau has crust up to 80km thick: a few authorities interpret this as being due to A-subduction of the crust of the Indo-Australian Plate after collision in the Eocene, but most attribute the thickness to internal thrusting since the early Mesozoic.
