Antler orogeny age of the Roberts Mountains thrust to coincide with the Late Devonian to Mississippian Antler orogeny and to extend the name far beyond the Roberts Mountains. Over a period of 22 years numerous reports relating the Antler orogeny and Roberts Mountains thrust to plate convergence were published in various journals, and because their basic tenets have been widely accepted, they are here termed the conventional theories. The earliest effort to relate plate tectonics specifically to the Antler orogeny was briefly outlined by E.M. Moores: "A collision of this continental margin with a subduction zone dipping away from it in late
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
