Karoo Supergroup Karoo Supergroup The Karoo Supergroup is the most widespread stratigraphic unit in Africa south of the Kalahari Desert. The supergroup consists of a sequence of units, mostly of nonmarine origin, deposited between the Late Carboniferous and Early Jurassic, a period of about 120 million years. In southern Africa, rocks of the Karoo Supergroup cover almost two thirds of the present land surface, including all of Lesotho, almost the whole of Free State, and large parts of the Eastern Cape, Northern Cape, Mpumalanga and KwaZulu-Natal Provinces of South Africa. Karoo supergroup outcrops are also found in Namibia, Swaziland, Zambia, Zimbabwe and
Namaqua National Park km². The park is semi-desert, with hot and dry summers and cold winters with variable, generally sparse rainfall. Most precipitation occurs between May and August. The eastern part of the park receives more rainfall than the west. The park is located in Namaqualand, which lies within the Succulent Karoo. Namaqualand has an area covering 55,000 hectares, located in the northwest corner of Northern Cape Province. The park is part of the semi-desert Succulent Karoo biome, one of the most unusual biomes in the world. This biome is a biodiversity hotspot with the greatest biodiversity and the highest concentration of succulent
