[3] A decade later this continental collision was named the East African Orogeny, but it was also realised that this was not the simple bringing together of two halves.
The Gondwanide orogeny was an orogeny active in the Permian that affected parts of Gondwana that are by current geography now located in southern South America, South Africa, Antarctica, Australia and New Guinea. [1] The zone of deformation in Argentina extends as a belt south and west of the cratonic nucleus of Río de la Plata–Pampia. [2]
The Damara Belt is exposed in Namibia between the Congo and Kalahari cratons and continues southwards into the coastal Gariep and Saldania Belts and northwards into the Kaoko Belt. It is the result of closure of the Adamastor and Damara oceans and includes two horizons associated with a severe equator-ward glaciation explained by the Snowball ...
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.
Gondwana (/ ɡ ɒ n d ˈ w ɑː n ə /) [1] was a large landmass, sometimes referred to as a supercontinent.The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia, Zealandia, Arabia, and the Indian Subcontinent.
In the Central Belt the cleavage transects folds in a clockwise sense and is accompanied by a sub-horizontal stretching lineation. In the Southern belt the Tinure Fault is the surface expression of the Iapetus Suture zone. [38] The Leinster terrane is the continuation of the Lakesman terrane in the Lake District of England and the Isle of Man ...
