On the origin of orogens
http://large.stanford.edu/courses/2013/ph240/malyshev2/ WebFormation of an orogen is accomplished in part by the tectonic processes of subduction, where a continent rides forcefully over an oceanic plate (noncollisional orogens), or convergence of two or more continents (collisional orogens). [5] Orogeny usually produces long arcuate (from arcuare, to bend like a bow) structures, known as orogenic belts.
