CoachA collision orogen is an orogen built by the convergence of two continental margins after the ocean between them has been consumed; its axis is a suture. An Andean-type orogen is an orogen built on the overriding plate of an ocean–continent subduction zone, while subduction goes on beneath it; its axis is a volcanic arc.
