Résumé

absolute age Africa Archean crust dates evolution folds French Bob's Granite greenstone belts Igneous and metamorphic petrology igneous rocks isoclinal folds Kaapvaal Craton MacKop Conglomerate Maranda Granite metamorphic belts Murchison greenstone belt Neoarchean nesosilicates orthosilicates Precambrian rhyolites Rooiwater Complex Rubbervale Formation silicates South Africa Southern Africa Structural geology Transvaal region U/Pb volcanic rocks Weigel Formation Witwatersrand zircon zircon group
The isotopes and metallogeny are discussed. Data give evidence for a greenstone belt on the Kaapvaal craton which is younger than the Barberton sequence.
