When two tectonic plates meet it is like the immovable object meeting the unstoppable force. However tectonic plates decide it by mass. The more massive plate, normally a continental will force the other plate, an oceanic plate down beneath it. This is the subduction zone. When the other plat...
This subduction process frequently occurs because of the two different types of lithosphere that make up tectonic plates: Continental and oceanic. Because oceanic material is denser than continental lithosphere, when the two collide at a subduction zone, the oceanic portion sinks into the mantle beneat...
Is oceanic lithosphere recycled to the subduction zone? What happens when tectonic plates of different densities collide? How are igneous rocks formed from a subduction zone? What happens after magma is formed? What kinds of geologic features form at subduction zones? What typically occurs along the...
This ‘biological carbon pump’ is a critical component of the global carbon cycle, reducing atmospheric CO2 levels by ~200 ppm relative to a world without export flux. This carbon flux also fuels the productivity of the mesopelagic zone, including important fisheries. Here we show that, ...
The subduction, rollback and retreat of the western Pacific Plate cause the delamination, horizontal mantle flow and continental crust extension of the NCC. The red trapezoidal area represents the low-velocity zone formed by the subducting slabs squeezing out the water in the mantle transition zone...
鈥擜2-D finite-element-method (FEM) numerical experiment of earthquake cycles at a subduction zone is performed to investigate the effect of viscoelasticity of the earth on great interplate earthquake fault slip. We construct a 2-D viscoelastic FEM model of northeast Japan, which consists of an...
Slow slip events (SSEs) are identified as the quasi-stable fault deformation in the deep transition zone from locked to continuous sliding in many subduction zones. In the well-instrumented Cascadia margin, a class of M6.0 slow slip events arise beneath Port Angeles every ˜14 months, as inf...

Palinspastic map reconstructions and plate motion studies reveal that switches in subduction polarity and the opening of slab gaps beneath the Alps and Din
The high seismic reflectivity zone above and in-between the conductive pathways reflects the brittle-ductile transition itself, which is known to have a quick succession of strong and weak layers separated by mid-crustal detachment faults23. This zone (R1) also dips towards the colder Craton ...
