Trench-parallel fast axes of seismic anisotropy due to fluid-filled cracks in subducting slabs
TLDR
In this paper, the authors describe field evidence for brittle hydrofracture in previously subducted rocks from the Western Alps, with a free aqueous fluid phase produced by dehydration reactions in the host blueschists and serpentinites.About:

From mantle to crust: Stretching the Mediterranean
TL;DR: In this article, a compilation of SKS fast splitting directions is used to give an image of flow lines in the mantle around the Mediterranean subduction zones and a comparison with stretching and shear directions in metamorphic core complexes that show the pattern of deformation at the scale of the middle and lower crusts.
Journal ArticleDOI
Constraints on subduction geodynamics from seismic anisotropy
TL;DR: In this article, the authors review the observational constraints on seismic anisotropy in subduction zones and discuss how seismic data can place constraints on wedge, slab, and sub-slab anisotropic.
Journal ArticleDOI
Water in the slab: A trilogy
TL;DR: 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.

Fluid flow during slab unbending and dehydration: Implications for intermediate‐depth seismicity, slab weakening and deep water recycling
TL;DR: In this paper, the authors performed thermomechanical models of a dynamically subducting and dehydrating oceanic plate and showed that during slab dehydration, unbending stresses drive part of the released fluids into the cold core of the plate toward a level of strong tectonic underpressure and neutral (slab-normal) pressure gradients.

Subduction interface processes recorded by eclogite-facies shear zones (Monviso, W. Alps)
TL;DR: In this paper, the three major eclogite-facies shear zones found at the top of the Monviso ophiolite Lago Superiore Unit were studied.

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.

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.
