East African Orogeny scenario are two coeval events: the collisions between India and Australia-East Antarctica and Azania and India. Furthermore, the two orogens of the latter scenario intersect in Madagascar, the proposed location of the Azania-India collision, and this part of the Kuunga Orogeny should be renamed the Malagasy Orogeny. The East African orogeny resulted in the formation of an enormous mountain chain, known as the Transgondwanan Supermountain, which was more than -long and -wide. The sedimentary deposition from this mountain chain, known as the Gondwana Super-fan, exceeded or the equivalent to covering the United States with of sediment, lasted for 260 million
Pampean orogeny Belt of the Brasiliano Orogeny, but in difference to the Paraguay Belt that ended up in the interior of Gondwana the Pampean Orogen remained at a continental margin. The orogen eventually ceased activity and was succeeded by the Famatinian orogeny further west. The eastern magmatic belt of the Pampean orogeny is interpreted as the remains of a volcanic arc associated with an east-dipping subduction zone while the western one is thought to represent a younger volcanic arc that developed on what was once the accretionary prism of the orogen. There have been differing views among geologists on the tectonic and
