Cycling water through the transition zone The water cycle involves more than just the water that circulates between the atmosphere, oceans, and surface waters. It extends deep into Earth's interior as the oceanic crust subducts, or slides, under adjoining plates of crust and sinks into the mantle, carrying water with it. Schmandt et al. combined seismological observations beneath North America with geodynamical modeling and high-pressure and -temperature melting experiments. They conclude that… Expand
Dehydration Melting Below the Undersaturated Transition Zone
A reflector 70-130 km below the base of the transition zone beneath Tibet is observed in receiver functions and underside seismic reflections, at depths consistent with the transition of garnet toExpand
Water and partial melting of Earth's mantle
Water plays a crucial role in the melting of Earth’s mantle. Mantle magmatisms mostly occur at plate boundaries (including subduction zones and mid-ocean ridges) and in some intraplate regions withExpand

Distribution, cycling and impact of water in the Earth's interior
The Earth's deep interior is a hidden water reservoir on a par with the hydrosphere that is crucial for keeping the Earth as a habitable planet. In particular, nominally anhydrous minerals (NAMs) inExpand
Deep mantle melting, global water circulation and its implications for the stability of the ocean mass
Oceans on Earth are present as a result of dynamic equilibrium between degassing and regassing through the interaction with Earth’s interior. We review mineral physics, geophysical, and geochemicalExpand
Fate of water transported into the deep mantle by slab subduction
Abstract The roles of water in the mantle transition zone, lower mantle, and the core-mantle boundary are investigated. The evidence for a wet mantle transition zone has been suggested based onExpand
Hydrous magnesium-rich magma genesis at the top of the lower mantle
TLDR
Compared with the seismological lower mantle, the experimental melt is gravitationally lighter; thus, a similar melt could be observed as seismological low-velocity zone at the lower mantle’s top. Expand
Hydrous minerals and the storage of water in the deep mantle
Abstract Water is transported into the deep mantle via hydrous minerals in subducting slabs. During subduction, a series of minerals in these slabs such as serpentine or chlorite, Mg–sursassiteExpand
Seismic evidence for water transport out of the mantle transition zone beneath the European Alps
Abstract The mantle transition zone has been considered a major water reservoir in the deep Earth. Mass transfer across the transition-zone boundaries may transport water-rich minerals from theExpand
A role for subducted super-hydrated kaolinite in Earth’s deep water cycle
Water is the most abundant volatile component in the Earth. It continuously enters the mantle through subduction zones, where it reduces the melting temperature of rocks to generate magmas. TheExpand

Whole-mantle convection and the transition-zone water filter
TLDR
It is proposed that the transition-zone water-filter model can explain many geochemical observations while avoiding the major pitfalls of invoking isolated mantle reservoirs. Expand
Hydrous mantle transition zone indicated by ringwoodite included within diamond
TLDR
X-ray diffraction, Raman and infrared spectroscopic data are reported that provide the first evidence for the terrestrial occurrence of any higher-pressure polymorph of olivine: ringwoodite is included in a diamond from Juína, Brazil, providing direct evidence that, at least locally, the transition zone is hydrous.

Stability of hydrous melt at the base of the Earth's upper mantle
TLDR
It is inferred that hydrous magma formed by partial melting above the 410-km discontinuity may indeed be gravitationally stable, thereby supporting the idea that low-velocity or high-attentuation regions just above the mantle transition zone may result from the presence of melt. Expand

Possible density segregation of subducted oceanic lithosphere along a weak serpentinite layer and implications for compositional stratification of the Earth's mantle
Abstract There is growing evidence that the top part of the oceanic mantle is pervasively serpentinized prior to subduction. Because the interior of a subducting slab heats up slowly, theExpand
Global electromagnetic induction constraints on transition-zone water content variations
TLDR
The results support the view that at least some of the water in the transition zone has been carried into that region by cold subducting slabs, and reveal variations in the electrical conductivity of the Transition zone of approximately one order of magnitude. Expand

Vapour undersaturation in primitive mid-ocean-ridge basalt and the volatile content of Earth's upper mantle
TLDR
The undersaturated pre-eruptive volatile content for a suite of mid-ocean-ridge basalts from the Siqueiros intra-transform spreading centre is reported, leading to correlations between volatiles and refractory trace elements that provide new constraints on volatile abundances and their behaviour in the upper mantle.
