Nature Communications, 2021 The mechanism of subduction initiation is a key to modern plate tectonics. Here, using numerical modeling and geological observations, the authors find that the majority of active and paleo subduction zones with metamorphic soles likely formed during ...

Geosystems and Geoenvironment, 2022 Initiation of new subduction zones is an integral part of Earth's plate tectonics regime. It is generally accepted that the negative buoyancy of sufficiently old oceanic lithosphere provides the primary driving force for subduction initiation.

Water transfer to the deep mantle through hydrous, Al-rich silicates in subduction zones [PDF]
, 2021 Constraining deep-water recycling along subduction zones is a first-order problem to understand how Earth has maintained a hydrosphere over billions of years that created conditions for a habitable planet.

Understanding variations in deformation and seismic behavior at subduction zones [PDF]
, 2021 Subduction zone faults accommodate relative plate motions with spatially varying deformation and seismic behavior. Subducting topography and sediment properties play a key role in modulating the deformation and seismic behavior. We studied two subduction

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.

Noble gases recycled into the mantle through cold subduction zones [PDF]
, 2017 Subduction of hydrous and carbonated oceanic lithosphere replenishes the mantle volatile inventory. Substantial uncertainties exist on the magnitudes of the recycled volatile fluxes and it is unclear whether Earth surface reservoirs are undergoing net ...

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen
Geological Journal, EarlyView.By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Numerical analysis of deformation in the upper part of subduction zones [PDF]
, 1981 The stresses and deformation in an accretionary prism, and the crystalline basement behind and beneath it, have been modelled using finite element analysis, assuming a visco-elastic Maxwell rheology for the rocks involved.
