Subduction zonesare convergent plate boundaries involving at least one oceanic plate. The oceanic plate descends beneath the other into the deep mantle, forming a deep-sea trench, often a volcanic arc subparallel to it, an inclined Wadati–Benioff seismic zone, and other subparallel deforming belts...
sub·duc·tion zone (səb-dŭk′shən) A convergent plate boundary where one plate sinks (subducts) beneath the other, usually because it is denser. See more at tectonic boundary. The American Heritage® Student Science Dictionary, Second Edition. Copyright © 2014 by Houghton Mifflin...
A subduction zone is a convergent tectonic boundary where one plate slides beneath another. Oceanic crust is required for one to initiate. The colder, denser plate will bend and slide beneath the other warmer and more buoyant one. What happens at a subduction zone? At subduction zones, one pl...

The definition of subduction is the process that occurs when two tectonic plates meet at convergent boundaries, and one of the plates moves under the other one due to gravity and differences in density. The boundary area where this occurs is the subduction zone. In the image below, an ...
We test the role of the advance rate (indentation rate) of the India–Eurasia convergent boundary, i.e. the Indian continental subduction zone hinge and slab (vI), relative to the rollback rate of the Western Pacific (vWP) and Sunda (vSu) subduction zones on the style and extent of cont...
36. Mineral assemblages constrain brecciation to a depth range of 30–80 km in the Alpine subduction zone, thus consistent with the CH4formation conditions. We suggest that the migration and accumulation of CH4-H2-rich fluids below a permeability seal, possibly promoted by CH4and H2...
"This shows that the margin is not passive anymore but is now being reactivated, i.e. a new convergent plate boundary is forming," Duarte said. "If you were looking for an embryonic subduction zone this is what you would expect to see." Sharing subduction The researchers suspect that the...
In some sections, it shows unconformable relation with the overlying cu- mulate ultramafic rocks signifying the physical existence of crust- mantle boundary (~petrological Moho). Exposures of cumulate peridotites and gabbros have been encoun- tered to the northeast of Moki, north of Washelo, The...
