The East African Orogen (EAO) marks one of earth’s greatest collision zones, a global feature in space (about 6000 km long where it is preserved in Africa and Antarctica; Fig. 1) and in time (350 million years of evolution) (Stern, 1994). The EAO formed when fragments of East and West Gondwana collided, beginning ~630 Ma ago (Meert, 2003). The southern part of the EAO is also known as the Mozambique Belt and is thought to be where the most intense continent-continent collision occurred. The Mozambique Belt is thus dominated by deformed, metamorphosed, and anatectically reworked older crust <...>
