East African Orogeny

Western Gondwana Orogens and Kuungan Orogens

East African Orogeny is the Neoproterozoic orogeny that affects the East African Orogen.^[1] The orogeny evolved from an accretionary orogeny involving the amalgamation of arcs and evolved into a collisional orogeny when the Neoproterozoic continent Azania^[2] collided with the Congo-Tanzania-Bangweulu Block at ~640 Ma.^[3] The orogeny is the earlier of two orogenies that affects the East African Orogen^[4] and is followed by the Ediacaran-Cambrian Kuunga Orogeny.^[4]
