Karoo Supergroup Malawi, as well as on other continents that were part of Gondwana. The basins in which it was deposited formed during the formation and breakup of Pangea. The type area of the Karoo Supergroup is the Great Karoo in South Africa, where the most extensive outcrops of the sequence are exposed. Its strata which consist mostly of shales and sandstones, record an almost continuous sequence of marine glacial to terrestrial deposition from the Late Carboniferous to the Early Jurassic. These accumulated in a retroarc foreland basin called the "main Karoo" Basin. This basin was formed by the subduction and orogenesis
Gulf of Oman desert and semi-desert Gulf of Oman desert and semi-desert The Gulf of Oman desert and semi-desert is a coastal ecoregion on the Persian Gulf and the Gulf of Oman in Oman and the United Arab Emirates at the northeastern tip of the Arabian Peninsula. The climate is hot and dry; the ecoregion contains a mixture of habitats including mangrove swamps, lagoons and mudflats on the coast, and gravelly plains and savanna with thorny acacia trees inland. The mangrove areas are dominated by "Avicennia marina" and the savanna by "Prosopis cineraria" and "Vachellia tortilis". Masirah Island is an important breeding area for the loggerhead
