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 ...
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 ...
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.
The Cape orogeny formed the Cape Fold Belt and the mountains that range along the Cape and the southern parts of South Africa. [3] An additional geological formation, the Msikaba Formation, found north of Port St. Johns in the Eastern Cape is considered to correlate with the Witteberg Group of the Cape Supergroup. [4]

Machine translation, like DeepL or Google Translate , is a useful starting point for translations, but translators must revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia.
The thin-skinned style of deformation is typical of many fold and thrust belts developed in the foreland of a collisional zone or back arc of a continental volcanic arc. This is particularly the case where a good basal decollement exists, usually in a weaker layer like a shale, evaporite, or a zone of high pore fluid pressure. [2]
A fold axis "is the closest approximation to a straight line that when moved parallel to itself, generates the form of the fold". [2] (Ramsay 1967). A fold that can be generated by a fold axis is called a cylindrical fold. This term has been broadened to include near-cylindrical folds. Often, the fold axis is the same as the hinge line. [3] [4]
