Journal ArticleDOI
The influence of H2O on mantle wedge melting
TL;DR: In this paper, the melting behavior of a primitive undepleted peridotite composition has been determined over a pressure range of 1.2-3.2 -GPa at H2O saturated conditions.
Journal ArticleDOI
The effect of H 2 O on the olivine liquidus of basaltic melts: experiments and thermodynamic models
Etienne Médard,Timothy L. Grove +1 more
TL;DR: In this paper, the effect of H2O on the liquidus temperature of olivine-saturated primitive melts was investigated, and it was shown that the effect does not depend on pressure or melt composition in the basaltic compositional range.
Journal ArticleDOI
Magma redox and structural controls on iron isotope variations in Earth's mantle and crust
Nicolas Dauphas,Mathieu Roskosz,Esen E. Alp,Daniel R. Neuville,Michael Y. Hu,Corliss Kin I Sio,François L. H. Tissot,Jiyong Zhao,Laurent Tissandier,Etienne Médard,Catherine Cordier +10 more
TL;DR: In this paper, the mean force constants of iron bonds in silicate glasses were measured by synchrotron Nuclear Resonant Inelastic X-ray Scattering (NRIXS).
Journal ArticleDOI
Oxygen fugacity, temperature reproducibility, and H2O contents of nominally anhydrous piston-cylinder experiments using graphite capsules
TL;DR: In this paper, the authors performed a series of experiments that place better constraints on the range of oxygen fugacity imposed by this capsule material, on the Fe 3+ /Fe 2+ ratios in experimentally produced melts and minerals, and on the temperature reproducibility in Pt-graphite capsules.
Journal ArticleDOI
Kinematic variables and water transport control the formation and location of arc volcanoes
Timothy L. Grove,Christy B. Till,Einat Lev,Nilanjan Chatterjee,Etienne Médard,Etienne Médard +5 more
TL;DR: It is demonstrated that the location of arc volcanoes is controlled by a combination of conditions: melting in the wedge is induced at the overlap of regions in the wedges that are hotter than the melting curve (solidus) of vapour-saturated peridotite and regions where hydrous minerals both inThe wedge and in the subducting slab break down.
