Cordilleran-type orogeny
http://csmres.jmu.edu/geollab/vageol/vahist/mtnmodel.html WebThe most important cause of cordilleran-type orogeny is the subduction of a mid-oceanic ridge, by which the volume of continental crust increases through the transfer of granitic melt from the subducting oceanic crust to an orogenic welt. Accretionary complexes are composed mainly of recycled granitic sediments with minor amounts of oceanic ...
