Abstract

The Mozambique Belt, which runs the length of eastern Africa, was thought to have formed during the collision of a fully assembled east Gondwana with west Gondwana during the East Africa Orogen (EAO). Subsequent work demonstrated that the elements of the Gondwana super-continent were distributed along the margins of Laurentia in the antecedent super-continent of Rodinia. It was quickly recognized that west Gondwana was an amalgam of cratonic elements assembled in the latter part of the Neoproterozoic during the Brasiliano and “Pan-African” orogenic episodes (ca. 630–500 Ma). East Gondwana was traditionally depicted in Rodinia as a coherent landmass composed of Australia, the East Antarctic eraton, India, Madagascar, and Sri Lanka.
