The detailed petrogenesis of mafic sills occurring throughout southern Africa provides strong support for the development of an Umkondo large igneous province on the eastern margin of the Kalahari craton at 1.1 Ga. The sills are most extensively developed in the Waterberg and Middelburg basins in no...
