Under extreme conditions of high pressure and temperature, liquids can undergo substantial
structural transformations as their atoms rearrange to minimise energy within a more …

To better understand the solution of volatile species in a reduced magma ocean, we identify
via Raman spectroscopy the nature of COHN volatile species dissolved in a series of …

Most economically important tungsten (W) deposits are of magmatic-hydrothermal origin.
The species and partitioning of W during fluid exsolution, considered to be the controlling …

Résumé New Raman and NMR spectroscopy data on hydrous Ca aluminosilicate melts and
glasses, with eutectic quartz–anorthite–wollastonite composition, are presented here. The …

A series of hydrothermal diamond anvil cell experiments was conducted to constrain the
equilibrium distribution of molecular H 2 between H 2 O-saturated sodium aluminosilicate …

Despite its low abundance, water has a great influence on the geodynamics of the Earth's
upper mantle. Indeed, water has the ability to modify the phase relations and to affect in a …

We report abundances of major trace and volatile elements in an orthopyroxenite vein
cutting a sub-arc, mantle-derived, spinel harzburgite xenolith from Kamchatka. The …

A new diamond-anvil cell apparatus for in situ synchrotron X-ray diffraction measurements of
liquids and glasses, at pressures from ambient to 5 GPa and temperatures from ambient to …

The acoustic velocities of three series of alkali-rich hydrous silicate glasses were determined
at ambient conditions using ultrasonic interferometry. The sound velocities and calculated …

We report the abundances of major and lithophile trace elements and volatiles (H 2 O, Cl
and S) in orthopyroxenite veins cutting mantle-derived, spinel harzburgite xenoliths from the …
