Type D: Sedimentary-hosted, Volcanic-related Resource:
No definition has been provided for this term.


Sedimentary-hosted volcanic-related resources are special in that the reservoirs are heated by magmatic activity and hosted in particularly porous media.

For example: the geothermal fields of the Salton Trough (California Rift Zone) occur over a rift that has been infilled by sediments.

According to Brophy, sedimentary-hosted, volcanic-related resources typically have the following properties:

  • Topography – Usually low topography
  • Climate – Arid, low precipitation
  • Depth to resource – Intermediate (2000-3500m)
  • Surface manifestations – Very restricted
  • Permeability – Variable
