: They are a kind of high temperature field but in wich the content off water and permeability is improved artificially by means of hydraulic fracture (the same method used in unconventional hydrocarbons resources).An example of this is the Soultz-sous-Forets Geothermal Field in France,where the heat source is a fractured granitic pluton
