Basalt eruptions blanketed the Karoo Supergroup in the Mesozoic and Zambia shifted to coal and sandstone formation. Geologically recent windblown sands from the Kalahari Desert and alluvial deposits near rivers play an important role in the modern surficial geology of Zambia. The country has extensive natural resources, particularly copper, but ...

No marine source rocks have been identified. In the Mid-Zambezi area and Cabora Bassa basin, the source rocks are gas-prone, carbonaceous to coaly mudstones and coal of Lower Karoo age. In the Cabora Bassa basin, similar gas-prone source rocks occur in the Upper Karoo .
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 ...
Hydrocarbon source rock potential of the Karoo in Zimbabwe Hydrocarbon source rock potential of the Karoo in Zimbabwe Hiller, K.; Shoko, U. 1996-07-01 00:00:00 The hydrocarbon potential of Zimbabwe is tied to the Karoo rifts which fringe the Zimbabwe Craton, i.e. the Mid-Zambezi basin/rift and the Mana Pools basin in the northwest, the Cabora Bassa basin in the north and the Tuli-Bubye and ...
A palynological investigation of three boreholes in the Lower Karroo of the Kazinze area of the Siankondobo coalfield (GS 31, 35 and 36), has indicated pollen and spore assemblages in the coal measures and underlying arenaceous beds.
Karoo is well represented along the Zambezi river valley forming several intra-cratonic basins separated by horsts consisting of igneous and high grade metamorphic Proterozoic rocks. One of the main horst blocks is located be-tween the Cahora Bassa region and Tete city, separating the Middle Zambezi Basin and the Lower Zambezi Basin.
Coal fly ash can be used in in various configurations (e.g. as cap, bottom liner, or blending) at a mine site, but comparative studies investigating their capacity to control acid mine drainage are limited. ...

Oct 21, 2019· Coal deposit locations in Mashonaland West Province Geology of the Mana Pools area deposits General geology. The area is predominated by sediments of the Karoo Supergroup i.e. the lower and upper Karoo, and Jurassic material. These deposits lie within the Mana Pools basin which is bound to the north by a fault which is interpreted as a half-graben.
The Lower Karoo Group comprises only 1000-1500m of this sequence, and is represented by periglacial sediments and turbidites of the Kondo Pool Formation and lacustrine sands tone, coal and carbonaceous shale of the Mkanga Formation (Table 1). The main subsidence of the basin took place during Upper Karoo times, when up to 7 OOOm of

ing Karoo time, the lithostratigraphic character of the ''Karoo sequence'' also changes significantly across the African continent. For this reason, the Karoo basins sensu stricto, which show clear similarities with the main Karoo Basin of South Africa, are generally restricted to south-central Africa (Fig. 1). To the north of the ...

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 ...
May 16, 2007· Data concerning organic petrology and thermal maturity of Lower Karoo coal measures (Lower Permian) are of considerable importance in determining the hydrocarbon potential of sediments in the rift-valley and half-graben complexes of the Luangwa and Zambezi valleys of eastern and southern Zambia, respectively, and in the extensive sedimentary basin developed on relatively stable .
The Lower Karoo corresponds to the lower portion of the Karoo Supergroup sequence. The basal unit comprises glacial tillites, being the Dwyka Formation in the Mid-Zambezi Basin, Basal Beds in the Limpopo basins and Kondo Pools Formation in the Mana Pools and Cabora Bassa Basins. These are overlain in the Mid-Zambezi by the Wankie sandstones and coal and the Madumabisa Mudstone

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.
