TL;DR: The Waterberg, Soutpansberg, Umkondo, and Matsap groups (Fig. 7-1) are of roughly equivalent age and are characterized by the ubiquitous presence of the earliest red beds, which provide significant information concerning the character of the Earth's early atmosphere as discussed by the authors.

TL;DR: By the end of the Cretaceous the present coastal configuration of southern Africa was established, but the evolving Cenozoic environments continued to respond to external influences as mentioned in this paper, and the depositional trends reflect not only the relative rates of sediment supply and local subsidence, but also the major eustatic sea level movements brought about by volumetric changes in ocean basins.

TL;DR: A 1,500m-thick chemical sedimentary unit within the approximately 2,300m.y.-old Transvaal Supergroup contains more than 75% dolomite as discussed by the authors.

TL;DR: In this paper, high-grade gneisses and granolites are exposed in two contrasting settings in southern Africa: (1) as scattered areas in granite-greenstone terranes (e.g., Kaapvaal Province) intruded by more-homogeneous granitoids and associated with predominantly low-grade supracrustal sequences, and (2) as extensive gniss terrans in "mobile belts" with subordinate intrusive rocks.
