Water in the slab: A trilogy
TLDR
In this article, the authors grouped the geological and geophysical phenomena associated with water in the slab into three different categories: those related to 1) the storage of water at the surface, 2) the subduction of a hydrated slab and 3) its dehydration that ultimately leads to mantle regassing.About:

The transport of water in subduction zones
TL;DR: The transport of water from subducting crust into the mantle is mainly dictated by the stability of hydrous minerals in subduction zones as discussed by the authors, and the thermal structure of subduction zone is a key to dehydration.

The subduction plate interface: rock record and mechanical coupling (from long to short timescales)
TL;DR: In this article, the authors used rocks recovered from subduction zones, together with insights from thermomechanical modelling, to provide a new dynamic vision of the nature, structure and properties of the plate interface and to bridge the gap between the mechanical behavior of active subducting zones (e.g.,coupling inferred from geophysical monitoring) and fossil ones (i.e.couplings required to detach and recover subducted slab fragments).

Water in the Earth’s Interior: Distribution and Origin
TL;DR: The Earth's total water content is estimated at $18.15 −15 −81 +81$ ∼ 3 times the equivalent mass of the oceans (or a concentration of $3900 −3300 +32700)~\mbox{ppm}$ weight H2O.

P and S wave tomography and anisotropy in Northwest Pacific and East Asia: Constraints on stagnant slab and intraplate volcanism
TL;DR: In this article, the authors determined three-dimensional P and S wave velocities and P wave azimuthal anisotropic tomography of the Northwest Pacific subduction zones by inverting 1,225,086 P wave and 335,117 S wave arrival times from 13,413 earthquakes.

Plate interface rheological switches during subduction infancy: Control on slab penetration and metamorphic sole formation
Philippe Agard,Philippe Yamato,Mathieu Soret,Christophe Prigent,Stéphane Guillot,Alexis Plunder,Benoît Dubacq,Alain Chauvet,Patrick Monié +8 more
TL;DR: In this article, the authors highlight two successive rheological switches across the subduction interface (mantle wedge vs basalts, then mantle wedge vs. sediments) during which interplate mechanical coupling is maximized by the existence of transiently similar rheologies across the plate contact.

The chemical composition of subducting sediment and its consequences for the crust and mantle
Terry Plank,Charles H. Langmuir +1 more
TL;DR: This article evaluated subducting sediments on a global basis in order to better define their chemical systematics and to determine both regional and global average compositions, and then used these compositions to assess the importance of sediments to arc volcanism and crust-mantle recycling, and to re-evaluate the chemical composition of the continental crust.
Journal ArticleDOI
The velocity of compressional waves in rocks to 10 kilobars: 1.
TL;DR: The velocity of compressional waves has been determined by measurement of travel time of pulses in specimens of rock at pressures to 10 kilobars and room temperature as mentioned in this paper, mainly igneous and metamorphic rocks, furnished three specimens oriented at right angles to one another.

Experimentally based water budgets for dehydrating slabs and consequences for arc magma generation
Max W. Schmidt,Stefano Poli +1 more
TL;DR: In this article, phase diagrams of hydrous mid-ocean ridge (MOR) basalts to 330 km depth and hydrous peridotites to 250 km depth are compiled for conditions characteristic for subduction zones.
Journal ArticleDOI
Age, spreading rates, and spreading asymmetry of the world's ocean crust
TL;DR: In this article, the authors present a digital model of the age, spreading rate, and asymmetry at each grid node by linear interpolation between adjacent seafloor isochrons in the direction of spreading.

Water in the oceanic upper mantle: implications for rheology, melt extraction and the evolution of the lithosphere
Greg Hirth,David L. Kohlstedt +1 more
TL;DR: In this paper, 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 experimental studies of olivine rheology.
