Alleghanian orogeny time period
WebThe Alleghanian orogeny occurred approximately 325 million to 260 million years ago over at least five deformation events in the Carboniferous to Permian period. The orogeny was caused by Africa’s collision with North America. What caused the Antler orogeny? West-dipping subduction WebThe antler orogeny occurred When Laurentia was carried into a subduction zone along its modern western border. A volcanic island arc formed and then converged on the continent, causing thrust faulting Where did the Antler Orogeny occur? West, in the Rockies. The next orogeny to occur in the Devonian is the Acadian orogeny
