...), Kaapvaal Craton, southern Africa, are two of the best exposed granite-greenstone belts. Their striking geological similarities has led to the postulated existence of Vaalbara, a Neoarchaean-Palaeoproterozoic supercraton. Although their respective TTG domes have been compared in terms of a common...

...Michael E. Evans; Adrian R. Muxworthy Vaalbara is the name given to a proposed configuration of continental blocks—the Kaapvaal craton (southern Africa) and the Pilbara craton (north-western Australia)—thought to be the Earth’s oldest supercraton assemblage. Its temporal history is poorly defined...

... of supercontinents, which still has no reliable proofs ( Condie, 2011 ). The known three dozens of Archean cratons appear to be fragments of large landmasses, judging by their similarity, and might have belonged to supercratons ( Bleeker, 2002 ). There are at least three groups of cratons sharing features...

The diachronous breakup of these supercratons in the Paleoproterozoic spawned the present ensemble of ca. 35 Archean cratons, which now are variably incorporated into younger crustal assemblies. Since the assembly of Nuna, the time...
