Extrusive magmatic plays are areas characterized by extrusive volcanism. Geological areas that include active volcanism are located at divergent plates boundaries(basaltic), converging ocean plates (andesitic/basaltic) at island arcs, and converging oceanic and continental plates (andesitic/dacitic). {{Cite|Moeck2014|A New 'Geothermal Play Type' Catalog: Streamlining Exploration Decision Making}}

Known magmatic geothermal plays associated with active volcanism include the [[Kilauea East Rift Geothermal Area|Kilaeau East Rift Zone]] in Hawaii.




According to Moeck and Beardsmore, magmatic geothermal plays associated with volcanic activity typically have the following properties:{{Cite|Moeck2014|Geothermal Plays in Geologic Settings}}
*'''Geologic Setting''' – Magmatic Arcs, Mid Oceanic Ridges, Hot Spots
*'''Heat Source/Storage Properties of Reservoir''' – Active Volcanism, Shallow Magma Chamber
*'''Dominant Heat Transport Mechanism''' – Magmatic-hydrothermal Circulation
