The Alleghanian orogeny formed when North America and Africa collided during the late Paleozoic era, specifically in the Carboniferous period. This event occurred between 325-260 million years ago and was responsible for the formation of the Appalachian Mountains. The Taconic orogeny occurred earlier, in the Ordovician period, and was related to the collision of Laurentia and Baltica. The Caledonian orogeny occurred in Europe and Greenland, while the Acadian orogeny occurred in the eastern region of North America during the late Devonian and early Carboniferous periods.
