Archaean Crystalline Rocks of the Eastern Kaapvaal Craton
The Kaapvaal Craton of southeastern Africa is one of the best preserved and best studied Archaean crustal segments worldwide and, together with the Pilbara Craton of Western Australia, has served as a global model for early Archaean granitoid-greenstone evolution (e.g. De Wit et al. 1992; Anhaeusser 2014; Van Kranendonk 2011 ).

Basalt, another dominant rock type in Kruger, is fine grained and composed mostly of feldspar, pyroxene and olivine. Chemical weathering readily reduces these minerals to clays and iron oxides, the final weathering product of which is a red or brown soil which now covers flat, featureless plains of eastern Kruger (Fig. 13.1 ).
