Karoo Supergroup - Wikipedia
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.
Karoo Supergroup - an overview | ScienceDirect Topics
Rocks of the Karoo Supergroup (159) crop out over almost two-thirds of southern Africa, and the strata record an almost continuous sequence of deposition from late Carboniferous to middle Jurassic, a period of about 100 million years. The sedimentary sequence represents environments ranging from glacial to arid, and is capped by basaltic lavas ...
