Controlling Structures

List of controlling structures typically associated with geothermal systems:

• Major Normal Fault
• Termination of a Major Normal Fault
• Stepover or Relay Ramp in Normal Fault Zones
• Apex or Salient of Normal Fault
• Fault Intersection

• Accommodation Zone
• Displacement Transfer Zone

• Pull-Apart in Strike-Slip Fault Zone
• Intrusion Margins and Associated Fractures
• Stratigraphic Boundaries
• Fissure Swarms
• Caldera Rim Margins
• Lithologically Controlled

Most high temperature geothermal areas in Iceland are found in regions of the country with many fissure swarms. http://mmillericeland.wordpress.com/category/iceland-overview/mapping-iceland/

Fissure swarms typically result from tensional forces in volcanic regions and are predominantly host to geothermal systems in Iceland.
