The minerals constituting the Earth's upper mantle are nominally anhydrous silicates
(NAMs). However they do contain hydrogen as a trace element, decorating point defects in …

Olivine, pyroxene and garnet are nominally anhydrous but can accommodate tens to
hundreds of parts per million (ppm) H2O or “water” in the form of protons incorporated in …

Trace-element compositions of olivine from 75 mantle rocks of diverse origin, including
xenoliths from kimberlites, basaltic lavas and orogenic peridotites, were determined by laser …

The lithosphere–asthenosphere boundary (LAB) is a first-order structural discontinuity that
accommodates differential motion between tectonic plates and the underlying mantle …

We present the results of an experimental study of the partitioning of water between common
upper mantle minerals (olivine, orthopyroxene, clinopyroxene, garnet) and silicate melt …

The onset of dehydration melting of nominally anhydrous peridotite can be calculated by
combination of appropriate mineral/melt partition coefficients for H2O, DHmin/liq, and a …

Lateral variations of seismic wave speeds and attenuation (dissipation of strain energy) in
the Earth's upper mantle have the potential to map key characteristics such as temperature …

For over 50 years, the use of high-pressure piston/cylinder apparatus combined with an
increasing diversity of microbeam analytical techniques has enabled the study of mantle …

Lattice diffusion coefficients have been determined for 19 elements (Li, Be, Na, Ca, Sc, Ti, V,
Cr, Mn, Fe, Co, Ni, Zn, Y, Zr, Eu, Gd, Lu and Hf) in a single crystal of San Carlos olivine as a …

The incorporation and diffusion of hydrogen in San Carlos olivine (Fo 90) single crystals
were studied by performing experiments under hydrothermal conditions. The experiments …
