Alleghanian orogeny the super-continent Pangaea, which contained all major continental land masses. The collision provoked the orogeny: it exerted massive stress on what is today the Eastern Seaboard of North America, forming a wide and high mountain chain. Evidence for the Alleghanian orogeny stretches for many hundreds of miles on the surface from Alabama to New Jersey and can be traced further subsurface to the southwest. In the north, the Alleghanian deformation extends northeast to Newfoundland. Subsequent erosion wore down the mountain chain and spread sediments both to the east and to the west. The immense region involved in the continental collision,
Damara orogeny Ma and 545–530 Ma Gariep Belt (Kalahari Craton, now in southern Africa). The Damara orogeny saw a peak in deformation and metamorphism at 530–500 Ma. Thrusting occurred onto the Kalahari Craton until 480 Ma. Río de la Plata docked to Congo before the closure of the Damara Belt oceans (Mozambique and Khomas) which made the Damara orogeny part of the Kuunga orogeny which stretched from Antarctica to India across Africa. All African cratons had been assembled by 550 Ma and the last stages of the Damara–Kuunga Orogeny (the final amalgamation of north and South Gondwana) were intra-cratonic. The Damara orogeny
