Exsolved volatiles in magma reservoirs
We review our understanding of the exsolved volatile phase co-existing with magmas during
pre-eruptive storage at the pressures and temperatures corresponding to crustal magma …

Machine learning thermobarometry and chemometry using amphibole and clinopyroxene: a window into the roots of an arc volcano (Mount Liamuiga, Saint Kitts)
The physical and chemical properties of magma govern the eruptive style and behaviour of
volcanoes. Many of these parameters are linked to the storage pressure (P) and temperature …

Effect of redox on Fe–Mg–Mn exchange between olivine and melt and an oxybarometer for basalts
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 …

Basalt derived from highly refractory mantle sources during early Izu-Bonin-Mariana arc development
The magmatic character of early subduction zone and arc development is unlike mature
systems. Low-Ti-K tholeiitic basalts and boninites dominate the early Izu-Bonin-Mariana …

Apatite volatile contents of porphyry Cu deposits controlled by depth-related fluid exsolution processes
Porphyry Cu deposits are formed by Cu-and volatile (eg, Cl, S)-rich fluids exsolved from
underlying magma reservoirs. Intuitively, higher magmatic Cl and S contents likely …

Petrology of the 2020–21 effusive to explosive eruption of La Soufrière Volcano, St Vincent: insights into plumbing system architecture and magma assembly …
Abstract The 2020–21 eruption of La Soufrière, St Vincent began with extrusion of a viscous
lava dome, which was destroyed upon transition to a major explosive phase. Here we …
