Stratigraphy of the Karoo Supergroup in southern Africa: an …

Abstract. The Karoo Supergroup in southern Africa occurs in the areally extensive Main Karoo and Kalahari basins as well as in a number of subsidiary basins in South Africa, Namibia, Botswana, Zimbabwe and Mozambique. The Main Karoo basin constitutes a retro-arc foreland basin, while the rest are intracratonic sag basins or rift …

An overview of the Permian (Karoo) coal deposits of southern Africa

The lithologies that contain the coal deposits are Permian in age and assigned to the Karoo Supergroup (SACS, 1980; Johnson et al., 1996), and Karoo-type deposits are known from all of the countries described in this paper (Fig. 1). The Karoo basin in South Africa is regarded as the type-locality for the southern African coals (Cadle et al., 1993).

Coal thickness is variable, but individual coals can be as much as 10-meters thick. Coal rank is reported to be high- to low-volatile bituminous with higher rank in the eastern part of the study area. Permian sedimentation in the Karoo Basin Province ended with extensive volcanism related to the breakup of the Gondwana supercontinent.
