Trans-Hudson orogeny Trans-Hudson orogeny The Trans-Hudson orogeny or Trans-Hudsonian orogeny was the major mountain building event (orogeny) that formed the Precambrian Canadian Shield, the North American Craton (also called Laurentia), and the forging of the initial North American continent. It gave rise to the Trans-Hudson orogen (THO), or Trans-Hudson Orogen Transect (THOT), (also referred to as the Trans-Hudsonian Suture Zone (THSZ) or Trans-Hudson suture) which is the largest Paleoproterozoic orogenic belt in the world. It consists of a network of belts that were formed by Proterozoic crustal accretion and the collision of pre-existing Archean continents. The event occurred 2.0-1.8 billion years ago.
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
