Subduction Zone:
A tectonic process in which one tectonic plate is forced beneath another and sinks into the mantle as the plates converge

Tectonic Settings

List of tectonic settings known to host modern geothermal systems:
A classic cartoon illustrating a typical simplified subduction zone. http://www.columbia.edu/~vjd1/subd_zone_basic.htm

Subduction zones occur where one tectonic plate is pulled under another. Most often the subducting plate is oceanic crust and contains many hydrous minerals. As the oceanic plate subducts it dewaters into the mantle, lowering the melting temperature of the surrounding mantle which causes flux melting of the mantle into magma. This magma rises up and creates volcanic arcs. These volcanic arcs have high heat flow from the magma plumes and related intrusives. The associated deformation and heat is conducive to high temperature (230-300°C) geothermal systems.

Though subduction zones and associated volcanic arcs are generally the most exploited tectonic settings for geothermal energy production throughout the world, the US has little development in its two major subduction induced volcanic arcs: The Cascades of the Pacific Northwest and the Aleutian Islands of Alaska.
