Antler orogeny Antler orogeny The Antler orogeny was an enigmatic tectonic event, that began in the early Late Devonian with widespread effects continuing into the Mississippian and early Pennsylvanian. Most of the evidence for this event is in Nevada but the limits of its reach are unknown. A great volume of conglomeratic deposits of mainly Mississippian age in Nevada and adjacent areas testifies to the existence of an important tectonic event, and implies nearby areas of uplift and erosion, but the nature and cause of that event are uncertain and in dispute. Although it is known as an orogeny (mountain building event),
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
