The concentration and distribution of water in the Earth has influenced its evolution
throughout its history. Even at the trace levels contained in the planet's deep interior (mantle …

Hydrous melting driven by changes in H2O storage capacity may occur in a variety of
settings in the mantle, including in oceanic basalt sources and in deeper regions above and …

The Hadean eon, following the global-scale melting of the mantle,–, is expected to be a
dynamic period, during which Earth experienced vastly different conditions. Geologic …

The Moon is generally thought to have formed and evolved through a single or a series of
catastrophic heating events, during which most of the highly volatile elements were lost …

We document compositions of minerals and melts from 3 GPa partial melting experiments on
two carbonate-bearing natural lherzolite bulk compositions (PERC: MixKLB-1+ 2· 5 wt …

The onset of partial melting beneath mid-ocean ridges governs the cycling of highly
incompatible elements from the mantle to the crust, the flux of key volatiles (such as CO2, He …

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 …

Early in terrestrial planet evolution energetic impact, radiodecay, and core formation may
have created one or more whole or partial silicate mantle magma oceans. The time to …

The solubility of H2O in silicate melt drops substantially with decreasing pressure, so that a
magma initially containing several weight percent H2O in a crustal magma reservoir is left …

Subduction zone basalts are more oxidized than basalts from other tectonic settings (eg,
higher Fe3+/∑ Fe), and this contrast may play a central role in the unique geochemical …
