▪ 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 …

Understanding the concentration and distribution of water in the Earth's mantle plays a
substantial role in studying its chemical, physical and dynamic processes. After a decade of …

The influence of water on the dynamics of the oceanic upper mantle is re-evaluated based
on recent experimental constraints on the solubility of water in mantle minerals and earlier …

Abstract The Bonin Ridge and trench slope preserves the geological record of subduction
initiation and subsequent evolution of the Izu–Bonin–Mariana (IBM) arc. Diving and …

The timing of delivery and the types of body that contributed volatiles to the terrestrial planets
remain highly debated,. For example, it is unknown if differentiated bodies, such as that …

We present the results of an experimental study of the partitioning of water between common
upper mantle minerals (olivine, orthopyroxene, clinopyroxene, garnet) and silicate melt …

It has been suggested that the longevity of cratons (ie ancient and stable cores of continents)
is related in part to the low water content of their deep mantle roots; this gives them a higher …

We have measured hydrogen partition coefficients between nominally anhydrous minerals
(olivine, pyroxenes) and basaltic melts in 13 hydrous melting experiments performed at …

Magmatic volatiles (for example, water) are abundant in arc melts and exert fundamental
controls on magma evolution, eruption dynamics and the formation of economic ore …

Differences in the viscosity of the earth's upper mantle beneath the western US (∼ 1018–
1019 Pa s) and global average values based on glacial isostatic adjustment and other data …
