Ancient Geology of the Ghaap Plateau
The Ghaap Plateau
The plateau is made up largely of calcrete, a mix of sand, gravel, clay and other materials cemented together by calcium carbonate. The calcrete is covered with sparse soil and sits on bedrock of dolomite or calcium manganese carbonate, containing numerous caves, sinkholes and underground waterways.
The Kuruman Hills
These low, rounded hills consist of blue asbestos (crosidolite), ironstone, slate and shale. The hills are also known as the Asbestos Hills", and for several decades became the centre of the Kuruman asbestos mining economy.
