The Karoo Supergroup lithologies have been intruded by dolerite dykes and sills and the possibly elevated Kalahari Group and Karoo Supergroup sedimentary rocks above the basin floor and exposed many of them combine existing data and present the resultant interpretations of Kalahari Basin evolution. Previously
tro-arc foreland basin (Johnson, 1990), the elongate, east-west striking Karoo Trough stretched over a distance of at least 700 km, being bordered in the north by a hinge line where it merged with the Kalahari Shelf, and in the south and west by a continuous moun- tain belt known as the Southern and Western. Highlands.
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

21 Dec 2017 Full-text (PDF) | Recent interest in the main Karoo Basin of South Africa has been sparked by the possibility of extensive shale gas resources. This approach indicates the importance of combining geological and The main Karoo Basin into which these dolerites intruded, was deposited from the.

Dwyka, Ecca, Beaufort and biozonation scheme for the Main Karoo Basin is proposed and the study provides . biostratigraphy of the Parana Basin, Brazil, combining.
seems to be essentially a stratigraphic equivalent, although of smaller extent, of the. Main Karoo Basin but without the Beaufort succession - the basin also merges north- eastwards into the Ellisras Basin (Figs 1.1 and 2.1). The Ellisras Basin may thus be considered an embayment of the much larger Kalahari Basin (Fig1.1).
the lithostratigraphic character of the Karoo Supergroup 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, whereas the Karoo-age successions
