The final collision zone between East and West Gondwana: Where is it?

The final collisional suture between East and West Gondwana is identified as the Nabitah Zone in Arabia. It can be traced through north central Kenya just east of the Baragoi ophiolite klippe, thence to the Cobue and Manica Belts, cutting across the eastern end of the Zambezi Belt, and finally to west Dronning Maud Land. There are misfits across the whole length of the suture. The collisional suturing, from 680 Ma to 550 Ma, involved compression and rotation about a hinge in the south. The rotation was less than the similar to 270 degrees or more interpreted from palaeomagnetic data. It is suggested that part of the rotation perhaps took place east of India and western East Antarctica. Copyright (C) 1997 Elsevier Science Ltd.
