Annual Review of Earth and Planetary Sciences, 2002 ▪ Abstract The subducted lithosphere is composed of a complex pattern of chemical systems that undergo continuous and discontinuous phase transformation, through pressure and temperature variations. Volatile recycling plays a major geodynamic role in triggering mass transfer, melting, and volcanism.

Timescales of subduction initiation and evolution of subduction thermal regimes
Earth and Planetary Science Letters, 2022 Subduction zones are first-order features of plate tectonics on Earth, yet the mechanisms by which subduction initiates remain enigmatic and controversial. Here, we reappraise the timing of metamorphism of the rock units first detached from the leading edge of the downgoing slab during initiation of the Neotethys subduction, now preserved in the ...

Deep fault sliding rates for Ka-Ping block of Xinjiang based on repeating earthquakes
Open GeosciencesThe seismically active Ka-Ping Block within Xinjiang, China, represents a zone of potential earthquake hazards, and existing surface measurements cannot fully reflect the area’s sub-surface slip rates.

Tectonic control on great earthquake periodicity in south-central Chile
Communications Earth & EnvironmentMulti-millennial records of great megathrust earthquakes have highlighted differences in periodicity and recurrence behavior. Understanding tectonic processes responsible for these differences is relevant for fault mechanics and hazard models.

Effect of a weak layer at the lithosphere-asthenosphere boundary on subduction dynamics [PDF]
, 2022 The aim of this thesis is to investigate and identify the first order effects of a weak layer at the lithosphere asthenosphere boundary (LAB) on a subduction zone, as to date, no previous geodynamics studies on this topic exist.

Evolution of tear faults in subduction zones: an analogue modelling perspective [PDF]
, 2020 Tear faults are common structures in subduction zones, especially at slab edges, where they origin from differential forces applied to a subducting slab in areas close to the trench.

The water and fluid-mobile element cycles during serpentinite subduction. A review
European journal of mineralogy, 2019 : The key role of serpentinites in the global cycles of volatiles, halogens and fl uid-mobile elements in oceans and in subduction zones is now ascertained by many studies quantifying their element budgets and the composition of fl uids they release during

Subduction termination through progressive slab deformation across Eastern Mediterranean subduction zones from updated P-wave tomography beneath Anatolia [PDF]
, 2018 Using finite-frequency teleseismic P-wave tomography, we developed a new three-dimensional (3-D) velocity model of the mantle beneath Anatolia down to 900 km depth that reveals the structure and behavior of the sub-ducting African lithosphere beneath ...
