Apex or Salient of Normal Fault

GEOTHERMAL ENERGY

Apex or Salient of Normal Fault:

Normal faults may intersect in the subsurface to form a fault apex or salient. Apices or salients of normal faults account for 3% of structural controls in the Great Basin.

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

Faulds uses this term as a structural control found in the Basin and Range province of the US.

Apices or salients of normal faults account for 3% of structural controls in the Great Basin.
