Magma reservoirs play a key role in controlling numerous processes in planetary evolution,
including igneous differentiation and degassing, crustal construction, and volcanism. For …

Field, geochronological and geophysical studies show that many igneous bodies are
emplaced incrementally, growing by accretion of successive magma sheets. The existence …

Differentiation of mantle-derived, hydrous, basaltic magmas is a fundamental process to
produce evolved intermediate to SiO 2-rich magmas that form the bulk of the middle to …

Most magmatism on Earth forms by direct melting of the mantle, generating basalts at the
low silica end of the terrestrial compositional spectrum. However, most subduction zone …

Differentiation of hydrous primary, mantle-derived magmas is a fundamental process to
generate evolved intermediate to SiO2-rich compositions forming the bulk of the continental …

The formation of amphibole cumulates beneath arc volcanoes is a key control on magma
geochemistry, and generates a hydrous lower crust. Despite being widely inferred from trace …

Porphyry deposits, our main source of copper and of significant amounts of Mo, Re and Au,
form at convergent margins in association with intermediate-felsic magmas. Although it is …

Chemical diversity in convergent margin magmas is a product of igneous differentiation in
crustal hot zones, vertically extensive regions characterised by a low-volume (< 20%) mobile …

Equilibrium crystallization experiments have been performed on a primitive high-MgO basalt
(HMB) from Soufrière, St. Vincent, with three initial H2O contents (0· 6, 2· 3 and 4· 5 wt%), at …

Porphyry copper deposits (PCDs) hosted in subvolcanic intrusions at convergent margins
are the primary world's copper resources. However, the set of magmatic processes that lead …
