The Cape Fold Belt is a fold and thrust belt of late Paleozoic age, which affected the sequence of sedimentary rock layers of the Cape Supergroup in the southwestern corner of South Africa. [1] It was originally continuous with the Ventana Mountains near Bahía Blanca in Argentina , the Pensacola Mountains (East Antarctica), the Ellsworth ...
The formation of the Cape Fold Belt is the result of a collision of tectonic plates that ended over 200 million years ago The accumulated strata of the Cape Supergroup and the older granites and Malmesbury group were raised and deformed by the pressure of the South American, Antarctic and African continental plates slowly moving together. The ...
The Cape Supergroup rocks later underwent deformation during the Cape orogeny, in which the rocks were folded and thrust upwards. The Cape orogeny formed the Cape Fold Belt and the mountains that range along the Cape and the southern parts of South Africa . [ 3 ]
Modelling of a fold and thrust belt in a sand box. A fold and thrust belt (FTB) is a series of mountainous foothills adjacent to an orogenic belt, which forms due to contractional tectonics. Fold and thrust belts commonly form in the forelands adjacent to major orogens as deformation propagates outwards. Fold and thrust belts usually comprise ...
The deformation of the orogeny is visible in the Sierra de la Ventana mountains in Argentina and the Cape Fold Belt in South Africa. The Gondwanide orogeny might have been linked with the roughly contemporary San Rafael orogeny of western Argentina.
Table Mountain. The geology of South Africa is highly varied including cratons, greenstone belts, large impact craters as well as orogenic belts.The geology of the country is the base for a large mining sector that extracts gold, diamonds, iron and coal from world-class deposits.
At around 600 miles wide and up to 6,000 meters (nearly four miles) deep, the Drake is objectively a vast body of water. To us, that is. To the planet as a whole, less so.
Such deformation is postulated to have had a role in the initiation of the Gondwanide Orogeny and formation of the Gondwanide Fold Belt, which includes the Sierra de la Ventana mountains north of Patagonia and the Cape Fold Belt of South Africa. [2]
