· Abstract The Pan‐African Orogen formed by convergence of numerous continental blocks during the Neoproterozoic to early Cambrian This convergence eventually led to amalgamation of Gondwana a supercontinent crosscut by a network of highly oblique linear orogenic belts that locally intersect each other as in NW Namibia where the NNW trending Kaoko Belt joins the NE trending Damara Belt

The Tectonic History of Africa UC Santa Barbara

The West African Mobile Belt is a Cenozoic relict area where materials eroded from the Afro Arabian Craton were deposited at the western continental margin Much of this area was later uplifted by continental displacement The Mobile Belt may have at one time been coterminous with the mobile belt along the eastern margin of North America that eventually gave rise to the Appalachian Mountains

The junction between Pan African mobile belts

In Namibia there is a junction between a Pan African age 650 450 orogenic system which follows the western rim of Africa and an ENE trending arm which branches off into eastern Namibia and Zambia The SE verging structures of this eastern arm were superimposed on earlier westward verging folds of the northern coastal belt The eastern arm was a zone of high temperature metamorphism and

PAN AFRICAN MOBILE BELTS AS EVIDENCE

Pan African belts of the African mainland and the Arabian Nubian Shield exhibit evolutionary features which are either compatible with intracontinental ensialic development or with plate margin and Wilson cycle tectonics Some of these belts are discussed and considered together they appear to reflect variations in crustal mobility during a transitional tectonic regime from intraplate to
