The virtually non-existent outcrops of the region are only weakly complemented by coal exploration borehole data (mostly available at the South African Council for Geoscience) which mainly detail the lower, coal-bearing Permian part of the Karoo succession. 3.

The Moatize Coalfield belongs to a network of continental Karoo basins of central Mozambique, known as the Zambezi Basin. Palynological and sedimentological studies were performed on four coal exploration boreholes to determine the age, depositional settings, and overall geological evolution of its extensive coal deposits.

1. Introduction. The accumulation of extensive coal deposits is one of the main features of the lower Karoo sedimentary sequences deposited in the Gondwanan basins of south-central Africa between the Late Palaeozoic Glaciation (LPG) and the end Permian mass extinction (Isbell et al., 2003, Isbell et al., 2012, Fielding et al., 2008, …

The coal-bearing sediments and coal seams of the Karoo Basin, Southern Africa are described and discussed. The Karoo Basin is bounded on its southern margin by the Cape Fold Belt, onlaps onto the ... Sediments of the Upper Carboniferous to Lower Jurassic Karoo Supergroup (∼ 4.5 km thick) were deposited in the mid-Zambezi Valley Basin, southern Zambia. The Upper Palæozoic Lower Karoo Group in this area ends with a Late Permian sedimentary unit called the Madumabisa Mudstone Formation. Late Carbonifeous to Permian core samples from two borehole sections, STRAT 1 and CKP 6, that penetrate the glacial to postglacial and coal-bearing Lower Karoo sequence, Kalahari Karoo … 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 Sinakumbe-Karoo succession represents deposition in a extensional fault-controlled basin of half-graben type. The basin-fill succession incorporates two major fining-upward cycles that resulted from major tectonic events, one event beginning with Sinakumbe Group sedimentation, possibly as early as Ordovician times, and the other … Samples with a mixed gas, condensate and oil potential (mainly kerogen types II and III) were identified in the Lower Karoo (Coal Measure and Lower Madumabisa Mudstone Formations) of the Mid ... The accumulation of extensive coal deposits is one of the main features of the lower Karoo sedimentary sequences deposited in the Gondwanan basins of south-central Africa between the Late ...
