CV-1a: Magmatic - Extrusive

From Open Energy Information


Dictionary.png
CV-1a: Magmatic - Extrusive:
extrusive refers to the mode of igneous rock formation in which hot magma from inside the Earth flows out (extrudes) onto the surface. Extrusive magmatic plays are areas characterized by extrusive volcanism.

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). [1]

Kilauea East Rift Zone Cross Section (Ref: https://www.soest.hawaii.edu)

Known magmatic geothermal plays associated with active volcanism include the Kilaeau East Rift Zone in Hawaii.



According to Moeck and Beardsmore, magmatic geothermal plays associated with volcanic activity typically have the following properties:[2]

  • 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
