Short summary
Short summary
Amphibole–liquid partitioning of elements of geological relevance is experimentally derived at conditions compatible with those of the Earth's upper mantle. Experiments are carried out at different oxygen fugacity conditions and variable Cl content in order to investigate their influence on the amphibole–liquid partition coefficients. Our results point to the capability of amphibole to act as filter for trace elements at upper-mantle conditions, oxidized conditions, and Cl-rich environments.

This work presents new thermoelastic parameters and the structural evolution of burbankite at high pressure and high temperature, obtained by in situ synchrotron radiation single-crystal diffraction measurements. Burbankite is a carbonate that may potentially play a key role as an upper-mantle reservoir of light REE3+. We observed that the density of burbankite is greater with respect to carbonatitic magmas, indicating a possible fractionation of this phase in upper-mantle conditions.

Magmas transport large amounts of CO2 from Earth's mantle into the atmosphere and thus contribute significantly to the global carbon cycle. We have developed an experimental method to homogenize at high pressure small liquid droplets trapped in magmatic crystals to gain access to the initial composition of the parental magma (major and volatile elements). With this technique, we show that magmas produced by melting of the subcontinental mantle contain several weight percent of CO2.

The mineralogical and chemical heterogeneity of the mantle is poorly known because it is not able to be directly investigated. Melt–peridotite interaction processes play a fundamental role in controlling the mantle composition. The results of our reaction experiments help us to evaluate the role of temperature and melt composition in the modification of the mantle through the interaction with pyroxenite-derived melts with implications for the evolution of a veined mantle.

This review provides an overview of ex situ carbon-saturated COH fluid experiments at upper-mantle conditions. Several authors experimentally investigated the effect of COH fluids. However, fluid composition is rarely tackled as a quantitative issue, and rather infrequently fluids are analyzed as the associated solid phases in the experimental assemblage. Recently, improved techniques have been proposed for analyses of COH fluids, leading to significant advancement in fluid characterization.

How, and how fast, does hydrogen move through crystals? We consider this question by adding hydrogen, by diffusion, to synthetic crystals of olivine doped with trace amounts of chromium. Even in a highly simplified system, the behaviour of hydrogen is complex. Hydrogen can move into and through the crystal using various pathways (different defects within the crystal) and hop between these pathways too.

Grain boundary diffusion is orders of magnitude faster compared to volume diffusion. We studied this fast transport process in a well-defined garnet grain boundary. State-of-the-art microscopy was used for quantification. A dedicated numerical diffusion model shows that iron diffusion requires the operation of two diffusion modes, one fast, one slow. We conclude that impurity bulk diffusion in garnet aggregates is always dominated by grain boundary diffusion.

We experimentally explored direct entrapment of breyite (CaSiO3) by diamond at upper-mantle conditions in a model subducted sediment rather than formation by retrogression of CaSiO3 perovskite, implying a deeper origin. Anhydrous low-T melting of CaCO3+SiO2 precludes breyite formation. Under hydrous conditions, reduction of melt results in graphite with breyite. Thus, breyite inclusions in natural diamond may form from aragonite + coesite or carbonate melt at 6–8 GPa via reduction with water.

Short summary
Detailed knowledge of the mechanisms ruling water incorporation in amphibole is essential to understand how much water can be fixed at upper-mantle conditions by this mineral. We provide the experimental evidence of the Cl effect on the oxo-substitution and the incorporation of water in amphibole. Finally, we highlight the versatility of confocal micro-Raman spectroscopy as an analytical tool to quantify water in amphibole.
