Crustal melting vs. fractionation of basaltic magmas: Part 1, granites and paradigms
Granitoids are a major component of the continental crust. They play a pivotal role in its
evolution, either by adding new material (continental growth), or by reworking older …

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 …

Crustal melting vs. fractionation of basaltic magmas: Part 2, Attempting to quantify mantle and crustal contributions in granitoids
Granitic melts may form either directly, by melting of pre-existing crustal rocks, or by
fractionation of mafic to intermediate magmas, typically mantle-derived. Each model is …
