35th International Geological Congress: Eastern Limb of the Bushveld Complex

The excellent exposures of the Eastern Limb have their origin in the uplift and erosion of the interior plateau of southern Africa. The resistant nature of the igneous rocks and metamorphic aureole has created a localized embayment in the Great Escarpment associated with the superimposed drainage of the Olifants and Steelpoort Rivers. The layered igneous rocks – the Rustenburg Layered Suite (RLS) – crop out spectacularly in a rugged landscape of linear and arcuate ridges.
