...V. van Schijndel; G. Stevens; C. Lana; T. Zack; D. Frei Abstract The formation and evolution of Palaeoarchaean De Kraalen and Witrivier Greenstone Belts (DKGB and WGB) of the Kaapvaal Craton are poorly known. Here we report zircon and rutile in situ U-Pb ages and zircon Hf isotopic data from...

.... These greenstone belt fragments include those at Dwalile, Assegaai, De Kraalen, Witrivier and Commondale ( Figure 1 ). The volcano-sedimentary succession that forms the Nondweni belt is referred to as the Nondweni Group ( du Toit, 1931 ; Linström, 1988 ). Based on field evidence and lithology, Versfeld (1988...

... between granitoid intrusions, greenstone belts and pre- to post-intrusive volcanic and sedimentary rocks are crucial for understanding the origin and evolution of continental crust in the Archaean. Isotopic signatures of granitoids provide information on the identity of their sources and give insight...
