Summary

Description In this diagram, the oceanic plate is subducting from left to right beneath the continental plate on the right. Surficial features diagnostic of a subduction zone include the bathymetric trench formed above the point of maximum bending in the down-going plate, the accretionary wedge of sediments that accumulates in the trench region, the forearc region where the continental crust tends to be stretched and thinned and sediments may accumulate, and the volcanic arc that overlies the zone where magma is generated by the interaction of fluids from the oceanic plate with deep rocks of the overriding plate (at about 100 km depth).
