We have experimentally investigated the fluid-absent melting of a phlogopite peridotite at
1.0 GPa (1000–1300° C) to understand the source of K 2 O-and SiO 2-rich magmas that …

Crystallisation-driven differentiation is one fundamental mechanism proposed to control the
compositional evolution of magmas. In this experimental study, we simulated polybaric …

Abstract The Fe–Mg exchange coefficient between olivine (ol) and melt (m), defined as Kd _
Fe^ T-Mg Kd Fe T-Mg=(Fe ol/Fe m)·(Mg m/Mg ol), with all Fe T expressed as Fe 2+, is one of …

Melting experiments have been performed at 3 GPa, between 1150 and 1450° C, on a
phlogopite-peridotite source in the garnet stability field. We succeeded to extract and …

Clinopyroxene–liquid geothermobarometry is a widely used tool for estimating the
conditions under which mafic magmas are stored before they erupt. However, redox …

We investigated the melting behavior of peridotite fluxed with 25 wt% of H 2 O-bearing
rhyolitic sediment melt (1.8 wt% bulk H 2 O), by performing experiments from 1100 to 1300° …

Whether arc mantle is more oxidized than oceanic mantle is persistently debated. The
behavior of multivalent vanadium (V) is oxygen fugacity (fO2) sensitive, and the ratios of V to …

This experimental study is the first comprehensive investigation of the melting behavior of an
olivine+ orthopyroxene±spinel—bearing fertile mantle (FM) composition as a function of …

Siliceous slab-derived partial melts infiltrate the sub-arc mantle and cause rock-melt
reactions, which govern the formation of diverse primary arc magmas and lithological …

The H2O storage capacities of peridotitic minerals place crucial constraints on the onset of
hydrous partial melting in the mantle. The storage capacities of minerals in equilibrium with …
