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

Arc-basaltic melts of typical hydration state (≥ 2 wt% H 2 O) are buoyant relative to all
common crustal igneous rock types and may pass adiabatically from a mantle source …

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 …

Magmatic processes on Earth govern the mass, energy and chemical transfer between the
mantle, crust and atmosphere. To understand magma storage conditions in the crust that …

Arc magmas, a major contributor to continental crust growth, are thought to be more oxidized
than mid-ocean ridge basalts as reflected by an enrichment in ferric iron relative to ferrous …

We review igneous experimental data designed to understand fractionation processes in the
roots of magmatic arcs, focusing on fractional crystallization experiments in dry and hydrous …

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 …

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

Protracted magma storage in the deep crust is a key stage in the formation of evolved,
hydrous arc magmas that can result in explosive volcanism and the formation of …

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 …
