Tectonic Settings

List of tectonic settings known to host modern geothermal systems:

Many geothermal areas may be considered to have no tectonic contribution to the geothermal resource. These areas are thought to have high heat flow resulting from high radiogenic sources beneath the crust, typically located within continental interiors.

For example, Chena Hot Springs in Alaska is located over a highly radiogenic granitic pluton. Chena’s back-arc setting, thought to be related to some rotation and extension, may provide the strain necessary to provide the faults and fractures for hydrothermal circulation.
