SUBDUCTION ZONES and ISLAND ARCS. Subduction Zones are where cool lithospheric plates sink back into the mantle. It takes about 50 my for the ocean lithosphere that formed in the hot (>1000C) environment at mid-ocean ridges to cool to an equilibrium state and sink to its maximum depth below sea-level.
