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 …

Melt inclusions in olivine are source of unique information about primitive mantle melts. Here
we report results of an experimental study aimed at evaluating the ability of olivine to isolate …

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 …

Manganese cobalt oxides with different Co/Mn ratios have been prepared by co-
precipitation methods, and their catalytic performance on methane combustion were …

Fifteen experiments at 1 atm pressure and 1400° C have been conducted to determine
partition coefficients between olivine and silicate melt (D Ol-m elt) of the first-row transition …

Elastic recoil detection analysis (ERDA) was used to measure the H contents of 18 synthetic
Fo90 olivines that had been hydrated to varying degrees in high pressure hydrothermal …

Experiments were performed under water-saturated conditions in the MFSH (MgO–FeO–
SiO2–H2O) and MFASH (MgO–FeO–Al2O3–SiO2–H2O) systems at 2.5, 5, 7.5 and 9GPa, at …

Synthetic hydroxylated titanium-bearing and undoped MgO-buffered forsterite crystals were
heated at atmospheric pressure in air at temperatures from 800 to 1200° C to determine …
