Abstract
Southern Africa’s landscape is characterised by a high plateau (elevation > 1,000 m) bound by escarpments and extensional continental margins, and the region has been influential in the development of geomorphological theory. However, the evolution of this landscape in response to tectonic and climatic forcing remains poorly understood, and is investigated here though an analysis of the topography and surface exposure history of early Jurassic (~183 Ma) Karoo dolerites.
