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
San Rafael orogeny San Rafael orogeny The San Rafael orogeny was an orogeny that affected parts of western Argentina and Chile during the Late Paleozoic. The resulting orogenic belt has a NW-NNW curved form. The San Rafael orogeny might have been linked with the roughly contemporary Gondwanide orogeny of eastern Argentina. Parts of the Choiyoi Group sediments were deformed by the San Rafael orogeny. During the Neogene ancient faults related to the San Rafael orogeny conditioned the geometry of the blocks affected by the Andean orogeny. Some of the plutons of the Elqui-Limarí Batholith were emplaced a context of crustal thickening derivative of
