Continental crust formation at arcs, the arclogite “delamination” cycle, and one origin for fertile melting anomalies in the mantle
CTA Lee, DL Anderson - Science Bulletin, 2015 - Elsevier
The total magmatic output in modern arcs, where continental crust is now being formed, is
believed to derive from melting of the mantle wedge and is largely basaltic. Globally …
