The transport of water from subducting crust into the mantle is mainly dictated by the stability of hydrous minerals in subduction zones. The thermal structure of subduction zones is a key to dehydration of the subducting crust at different depths. Oceanic subduction zones show a large variation in the geotherm, but seismicity and arc volcanism are only prominent in cold subduction zones where geothermal gradients are low. In contrast, continental subduction zones have low geothermal gradients… 
Metamorphism, fluid behavior and magmatism in oceanic subduction zones
Based on the updated results of experimental petrology and phase equilibria modelling and combined with the available thermal structure models of subduction zones, this paper presents an overview on
The study of subduction channels: Progress, controversies, and challenges
The subduction channel is defined as a relatively thin and weak zone with coherent kinematics between the descending and overriding plates during subduction. The materials in the channel, showing the
Continental versus oceanic subduction zones
Subduction zones are tectonic expressions of convergent plate margins, where crustal rocks descend into and interact with the overlying mantle wedge. They are the geodynamic system that produces
Dehydration at subduction zones and the geochemistry of slab fluids
Subducting oceanic slabs undergo metamorphic dehydration with the increase of temperature and pressure during subduction. Dehydration is an essential step for element recycling, and slab fluids are
Assessing the Role of Water in Alaskan Flat‐Slab Subduction
Low‐angle subduction has been shown to have a profound impact on subduction processes. However, the mechanisms that initiate, drive, and sustain flat‐slab subduction are debated. Within all
The stability of subducted glaucophane with the Earth’s secular cooling
TLDR
It is shown that the maximum depth of glaucophane stability increases with decreasing thermal gradients of the subduction system, implying that secular cooling of the Earth has extended the stability of glucophane and consequently enabled the transportation of water into deeper interior of theEarth, suppressing arc magmatism, volcanism, and seismic activities along subduction zones.
Subduction-zone peridotites and their records of crust-mantle interaction
Subduction is the core process of plate tectonics. The mantle wedge in subduction-zone systems represents a key tectonic unit, playing a significant role in material cycling and energy exchange

Fluid Processes in Subduction Zones
TLDR
The location and conse-quences of fluid production in subduction zones can be constrained by consideration of phase diagrams for relevant bulk compositions in conjunction with fluid and rock pressure-temperature-time paths predicted by numerical heat-transfer models.
Subduction factory: 4. Depth-dependent flux of H2O from subducting slabs worldwide
[1] A recent global compilation of the thermal structure of subduction zones is used to predict the metamorphic facies and H 2 O content of downgoing slabs. Our calculations indicate that
Faulting induced by precipitation of water at grain boundaries in hot subducting oceanic crust
TLDR
It is shown that at such pressures and temperatures, eclogite lacking hydrous phases but with significant hydroxyl incorporated as defects in pyroxene and garnet develops a faulting instability associated with precipitation of water at grain boundaries and the production of very small amounts of melt.
Common depth of slab‐mantle decoupling: Reconciling diversity and uniformity of subduction zones
Processes in subduction zones such as slab and mantle‐wedge metamorphism, intraslab earthquakes, and arc volcanism vary systematically with the age‐dependent thermal state of the subducting slab. In
Are the lower planes of double seismic zones caused by serpentine dehydration in subducting oceanic mantle
In a number of subduction zones, earthquakes at 50–200 km depth define two dipping planes, separated by 20–40 km, that appear to merge downdip. Upper plane earthquakes are inferred to occur within
