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 …

A paradigm shift has recently occurred in our knowledge and understanding of water in the
lunar interior. This has transpired principally through continued analysis of returned lunar …

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 …

We present here an historical overview of the early researches on proton conductor solids
for materials such as fuel cell, battery, electrolyser or H 2-sensor. Unexpectedly, the early …

The partitioning of H 2 O between a mantle peridotite assemblage and low degree hydrous
melt has been investigated at 6 GPa (corresponding to∼ 180 km depth) at a temperature of …

The study of the composition of primary melts during anatexis of high-pressure granulitic
migmatites is relevant to understand the generation and differentiation of continental crust …

Hydrogen is a volatile element involved in several geological processes ranging from rock
weakening to the initiation of tectonic plates. Because it is present in diamond, the …

The present study illustrates the interest of using the elastic recoil detection analysis (ERDA)
method to characterize any geological sample matrix with respect to hydrogen. ERDA is …

It is now recognized that the transition zone (TZ) is a significant repository for water. This
means that other volatile species may also be stored in this region such as halogen …

The mechanism and magnitude of fluorine incorporation in H-bearing forsterite were
investigated through a combined experimental and theoretical approach. Forsterite samples …
