Type F: Oceanic-ridge, Basaltic Resource:
No definition has been provided for this term.


Basaltic resources typically occur at oceanic-ridges, continental rifts, and hot spots. These geothermal systems are heated by magmatic activity and the exploited fluids are typically very high temperatures.

Examples of such resources include those in Hawaii, Iceland, and along the East African Rift.

According to Brophy, ocean-ridge, basaltic resources typically have the following properties:

  • Topography – Rugged to flat
  • Climate – Island – high precipitation
  • Depth to resource –Shallow (1000-2000m)
  • Surface manifestations - Common
  • Permeability – High horizontal permeability, variable vertical permeability
