The Appalachians first formed roughly 480 million years ago during the Ordovician Period. Then the most important orogeny phase (Alleghanian orogeny) saw NW Africa and Laurussia collide 325 million to 260 million years ago during the formation of Pangea forming mountains roughly parallel to the coast.
