Related to subduction: Subduction zone


A geologic process in which one edge of one crustal plate is forced below the edge of another.

[French, from Latin subductus, past participle of subdūcere, to draw away from below : sub-, sub- + dūcere, to lead; see deuk- in Indo-European roots.]

sub·duct′ v.
sub·duc′tal (-təl) adj.


1. (Physiology) the act of subducting, esp of turning the eye downwards
2. (Geological Science) geology the process of one tectonic plate sliding under another, resulting in tensions and faulting in the earth's crust, with earthquakes and volcanic eruptions


(səbˈdʌk ʃən)

the process by which collision of the earth's crustal plates results in one plate's being drawn down or overridden by another, localized along the juncture (subduc′tion zone`) of two plates.
[1965–70; < French subduction (1951); see subduct, -ion]


The sinking of one lithospheric plate’s leading edge below another lithospheric plate. This occurs below deep ocean trenches.
