Neoproterozoic reorganization of the Circum- Mozambique orogens and growth of megacontinent Gondwana

Abstract The serpentine orogenic belts that formed during the Neoproterozoic assembly of Gondwana resulted in geodynamic changes on planet advance Cambrian radiation. details associated with closure Mozambique Ocean are enigmatic. We compile published geological and paleomagnetic data to argue Tarim block was Azania Afif–Abas–Lhasa terranes they were locus long-lived Andean-type subduction ~900–650 Ma interval. Our model suggests a system reorganization between 750-720 Ma, which two distinct phases ocean evolution. Between 870-750 N-S oriented marks crust consumption driven by extension Ocean. Beginning ~720 newly developed ~E-W began consume led eastern Gondwana. new reconstruction uses true polar wander constrain relative paleolongitude Tarim, South China West Africa. In this scenario, formation orthogonal preceding supercontinent Rodinia.
