Porphyry copper deposit formation in arcs: What are the odds?
JP Richards - Geosphere, 2022 - pubs.geoscienceworld.org
Arc magmas globally are H2O-Cl-S–rich and moderately oxidized (ΔFMQ=+ 1 to+ 2) relative
to most other mantle-derived magmas (ΔFMQ≤ 0). Their relatively high oxidation state limits …
