Cyclicity in cordilleran orogenic systems
WebJun 15, 2024 · Models for Cordilleran magmatic cyclicity are supported by excellent control on plate tectonic boundary conditions, the timing of continental shortening events, and petrological data on igneous sources within the arc system (DeCelles et al., 2009, Paterson and Ducea, 2015). These controls are lacking in many other arc systems.
