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
East African Orogeny supercontinent (today known as Rodinia), a process that eventually culminated in the relatively short-lived Gondwanan supercontinent. Two partly incomparable scenarios have been proposed for this assembly. In one model, the EAO evolved from an accretionary orogeny involving the amalgamation of arcs and evolved into a collisional orogeny when the Neoproterozoic continent Azania collided with the Congo-Tanzania-Bangweulu Block at . In another model, the assembly of East Gondwana was a multiphase process which included two main periods of orogenesis: the older EAO ( ) and the younger Kuunga Orogeny ( ). In the former scenario the Kuunga Orogeny of the latter
