Cyclicity in cordilleran orogenic systems
WebMay 15, 2024 · The Cordilleran orogenic system in North America, extending up to 1500 km inboard from the inferred plate margin, has constituted a key region for such studies (Dickinson, 2004). WebJun 15, 2024 · Orogens are major sites for crustal growth on Earth. However, characterizing orogens with stages is challenging. Here we present Nd isotope mapping results of felsic and intermediate igneous rocks from eight well-studied, typical Phanerozoic orogens.
