Summary

Several clearly defined ore provinces pre-dating the disruption of Africa and South America during Jurassic and Lower Cretaceous times can be localized. The majority of these ore provinces is situated in the Late Precambrian orogenic belt folded and metamorphosed during the Pan-African—Brazilian Orogenic Cycle between 700 and 450 m. y. ago. The copper and lead-zinc ore provinces of South-west Africa, Zambia and South Brazil and the tin-tungsten mineralization of North-east Brazil and Nigeria are typical examples. The iron-, gold and diamond provinces separated by rifting and following continental drift on the other hand mainly are situated on older cratonic areas of Early or Middle Precambrian age.
