: These deposits are found in áreas of higher igneous activity.They are related to extremely high gradients, corresponding to global tectonic process.They occur in plate borders, cortical thinnes áreas or Hot Spots. They need an igneous source an aquifer and a impermeable layer to keep up pressure. In many cases there is surface evidence suchs as geysers and fumaroles, [[File: Simplified diagram of a geotermal power plant.png|thumbnail|center|Simplified diagram of a geotermal power plant.
