Inclusions of basaltic melt trapped inside of olivine phenocrysts during igneous
crystallization provide a rich, crystal-scale record of magmatic processes ranging from …

The amount of water dissolved in magmas at depth beneath volcanoes is fundamental to a
wide range of magmatic and eruptive processes due to water's dominant control on magma …

Ti-in-zircon thermometry has become a widely used tool to determine zircon crystallization
temperatures, in part due to reports of extremely sluggish Ti diffusion perpendicular to the …

Metamorphic olivine formed by the reaction of antigorite+ brucite is widespread in
serpentinites that crop out in glacier-polished outcrops at the Unterer Theodulglacier …

Granulites from Holsnøy (Bergen Arcs, Norway) maintained a metastable state until fluid
infiltration triggered the kinetically delayed eclogitization. Interconnected hydrous eclogite …

Arc basalts are oxidized relative to mid-ocean ridge basalts; however, the mechanism
through which arc basalts gain this elevated oxidative state is debated. This observation has …

Whilst the diffusivity of hydrogen (H) in forsterite (Mg2SiO4) has been extensively studied,
there still remain some puzzling observations. Firstly, experiments measuring ostensibly the …

Hydrogen is one of the most difficult elements to characterize in geological materials. Even
at trace levels, hydrogen has a major impact on the properties of minerals, silicate melts, and …

Garnet is a nominally anhydrous mineral that can incorporate several hundreds of ppm H 2
O in the form of OH groups, where H+ substitutes for cations in the garnet structure. To …

The oxidation states of dissolved iron (Fe) and sulfur (S) in silicate melts were studied
experimentally by heating Hawaiian olivines containing S-bearing melt inclusions (MIs) in a …
