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 …

Measurement of the rate of diffusion of hydrous species in anhydrous minerals has been a
subject of growing interest for the last ten years. Hydrogen diffusion studies are of …

Most minerals of Earth's upper mantle contain small amounts of hydrogen, structurally bound
as hydroxyl (OH). The OH concentration in each mineral species is variable, in some cases …

Several of the supposedly anhydrous major minerals of the upper mantle have been shown
to regularly contain small amounts of hydrogen. The concentrations measured in the most …

A suite of 51 pyroxenes from a wide range of geological environments was examined with
infrared spectroscopy. Small amounts of OH occur in nearly all the samples, suggesting that …

Reflectance spectroscopy is a powerful tool for the investigation of the nature, history,
evolution, and relationships between asteroids and meteorites. This information provides a …

Pyroxene water contents measured by Fourier transform infrared spectrometry for Mexican
and Simcoe (WA, USA) spinel-peridotite xenoliths range from 140 to 528 ppm in …

Abstract We present new Fourier Transform Infrared Spectroscopy (FTIR) and ion
microprobe/secondary ion mass spectrometry (SIMS) analyses of 1H in 61 natural and …

Infrared spectroscopy and ion micro-probe measurements showed that the major constituent
minerals of eclogites from the Kokchetav massif, which have been subducted to∼ 180 km …

A large number of studies of water in pyroxenes have confirmed that essentially all
pyroxenes of terrestrial origin as a rule contain substantial amounts of OH, varying as a …
