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
Malagasy orogeny Malagasy orogeny Malagasy orogeny is the name given to the Ediacaran to Cambrian orogeny that resulted as India collided with the already amalgamated African continent that consisted of Azania and the Congo-Tanzania-Bangweulu Block. The orogeny affected the parts of the East African Orogen that are now found in southern India, Madagascar and central Arabia. The term "Malagasy orogeny" was introduced by for the orogenisis between India and a series of Gondwanan cratonic blocks in present-day Africa (Congo/Tanzania/Bangweulu/Azania). In their reconstruction, India collided with Australia/Mawson in the Kuunga orogeny before the formation of Gondwana. They identified the Betsimisaraka suture in eastern
