CV-1a: Magmatic - Extrusive
From Open Energy Information
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.
Moeck-Beardsmore Play Types
This classification scheme was developed by Moeck and Beardsmore, as reported in A New 'Geothermal Play Type' Catalog: Streamlining Exploration Decision Making.[1]
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]
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
