▪ Abstract The mechanisms of exchange of hydrogen between the deep interior and surface
of Earth, as well as the means of retention and possible abundance of hydrogen deep within …

Variations in water (hydrogen) content in Earth's (upper) mantle can be inferred from
geophysical observations if the relationship between water content and rel evant physical …

The solubility of hydroxyl in the α, β and γ phases of (Mg, Fe) 2 SiO 4 was investigated by
hydrothermally annealing single crystals of San Carlos olivine. Experiments were performed …

Because of their distinct chemical signatures, ocean-island and mid-ocean-ridge basalts are
traditionally inferred to arise from separate, isolated reservoirs in the Earth's mantle. Such …

We determined P-wave tomography of the crust and upper mantle under the Changbai
volcanic area in Northeast Asia by using 289,318 arrival-time data from 4802 local …

We have measured amphibole-melt and phlogopite-melt partition coefficients (D) for 22
trace elements in experimentally crystallized natural basanites with the ion microprobe. The …

Material recycling in subduction zones, including the generation and migration of aqueous
fluids and melts, is key to understanding the origin of volcanism in subduction zones and is …

Various methods for inferring the water distribution in Earth's mantle are reviewed including
geochemical and geophysical methods. The geochemical approach using the water …

The presence of water strongly influences the structure, composition and dynamics of the
Earth's deep mantle,,,. Hydrous magnesium-rich silicates play an important role in …

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 …
