Oxidized primary arc magmas: Constraints from Cu/Zr systematics in global arc volcanics

SY Zhao, AY Yang, CH Langmuir, TP Zhao - Science Advances, 2022 - science.org
Arc volcanics are more oxidized than mid-ocean ridge basalts (MORB), but it is debated
whether this is a mantle feature or a result of magmatic evolution. Copper, a sulfur-loving …
