Location of this locality in the geological map (Williamson, 1991a) show the area to be underlain by sandstone members of the Mmamabula Formation i.e. KEm1 and KEm3. The latter are described in detail in Williamson (1996) and were also previously described as the Lower and Middle Mmamabula sandstones (BP Coal, Shell Coal, Amax, CdF, Smith 1984a).
expel oil, has been reported in coal fields in the Mid-Zambezi Basin northeast of Botswana (Oesterlen and Lepper, 2005). If liptinite is abundant in the macerals of the Karoo Surpergroup in the Nama Basin, oil generation could be expected. Oesterlen and Lepper (2005) showed that coal from the Lubimbi coal mine in the Karoo

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 ...
However, weaker global coal demand, lower international coal prices over the past few years, and some regulatory uncertainties have delayed investments in these mine projects.[12] Some of South Africa's mining projects are allocated to domestic electricity generation versus coal exports.
The lower coal zone (LCZ) palynoflora best correlates with Palynozone K4 in the MKB (equivalent to the Witbank No. 4 seam, Vryheid Formation) and can also be associated with Biozone D of the Waterberg Coalfield (Ellisras Basin), and the Vereeniging top seam in the New Vaal Colliery, northern Karoo Basin. The upper coal zone (UCZ) palynoflora of ...

The three formations constitute the Lower Karoo Group. The Gwembe Coal Formation represents fluvial deposition of sandstones, siltstones and mudstones in channels and on the floodplains. Fourteen lithofacies in the formation are grouped into four facies associations, namely Maamba Sandstone, Coal, Mudrock and Sandstone A facies.
The Great Karoo is itself divided by the Great Escarpment into the Upper Karoo (generally above 1200–1500 m) and the Lower Karoo on the plains below at 700–800 m. A great many local names, each denoting different subregions of the Great Karoo, exist, some more widely, or .
The Beaufort Group is the third of the main subdivisions of the Karoo Supergroup in South Africa.It is composed of a lower Adelaide Subgroup and an upper Tarkastad Subgroup. It follows conformably after the Ecca Group and unconformably underlies the Stormberg Group.Based on stratigraphic position, lithostratigraphic and biostratigraphic correlations, palynological analyses, and other means of ...

Collinson and Hammer: Migration of Triassic Tetrapods to Antarctica 3 environment for coal deposition had apparently shifted poleward as the southern Africa part of Gondwana moved into drier mid-latitudes. In the Karoo basin, meandering stream deposition was replaced at the Permian-Triassic boundary by low-sinuosity braided stream deposition.

Introduction Coal occurrence in Zimbabwe is restricted to areas which are host to the Karoo sedimentary Supergroup. Mashonaland is host to such a sedimentary sequence which is restricted to the northern and western parts of the province. Coal occurrence has been reported in the Mana Pools area which forms part of the Mid-Zambezi Valley of the Hurungwe District and in the lower Charara valley ...
The vegetation of the Upper and Lower Karoo is similar, so that few people make a distinction between the two. The main highway (the N1) and railway line from Cape Town to the north enter the "Lower Karoo" from the Hex River Valley just before Touws River and follow a course about 50 km south of the Great Escarpment up to Beaufort West.
