Karoo are exposed. These are locally known as the Cango Group, but are probably continuous with the Malmesbury Group that forms the base of Table Mountain on the Cape Peninsula, and similar outcrops in the Western Cape. In the Little Karoo, the outcrop is composed of limestone, into which an underground stream has carved the impressively extensive Cango Caves. The Great Karoo and Little Karoo lie almost entirely within two of South Africa’s eight botanical biomes, namely the Succulent Karoo biome and the Nama Karoo biome, both of which, like the Karoo Geological System, are more extensive than the geographical or
Hydraulic fracturing in South Africa reserve in the world. These figures, however, were based on desktop research and would only be refined through an extensive exploration programme In the present day, the Karoo is a semi-desert stretching over 400,000 square kilometers and home to a population of around 1 million people. The Karoo is divided into two regions: the Little Karoo, which is wet, and the Great Karoo, which is mainly desert. Because of certain exclusions, including topography and townships, around 28% of the Karoo has been estimated to be accessible to commercial development. Unique to the Karoo shale reserves is the presence of dolerite
