Subduction is a geological process in which the oceanic lithosphere and some continental lithosphere is recycled into the Earth's mantle at the convergent boundaries ...
The figure is a schematic diagram depicting a subduction zone. The subduction slab on the right enters the mantle with a varying temperature gradient while importing water in a downward motion. A model of the subducting Farallon slab under North America. In geology, the slab is a significant constituent of subduction zones. [1]
Simplified diagram of a convergent boundary. A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. . One plate eventually slides beneath the other, a process known as subduct
In plate tectonics, sutures are the remains of subduction zones, and the terranes that are joined are interpreted as fragments of different palaeocontinents or tectonic plates. Outcrops of sutures can vary in width from a few hundred meters to a couple of kilometers.
This driving force is important when the slabs (or portions thereof) are not strongly attached to the rest of their respective tectonic plate. They cause both the subducting and overriding plate to move in the direction of the subduction zone. [1] This force occurs between two colliding plates where one is subducting beneath the other.
Melt production and accretion of melt onto continental crust in a subduction zone [1]. A subduction zone is a region of the Earth's crust where one tectonic plate moves under another tectonic plate; oceanic crust gets recycled back into the mantle and continental crust gets produced by the formation of arc magmas.
This subduction zone was responsible for the 2004 Indian Ocean earthquake and tsunami. [15] In parts of the megathrust south of Java , referred to as the Java Trench , for the western part, M w 8.9 is possible, while in the eastern Java segment, M w 8.8 is possible, while if both were to rupture at the same time, the magnitude would be M w 9.1.
An oceanic plate is added to by upwelling (left) and consumed at a subduction zone (right). Mantle convection is the slow creeping motion of Earth's rocky mantle caused by convection currents carrying heat from the interior of the Earth to the surface. [33] It is one of 3 driving forces that causes tectonic plates to move around the Earth's ...
