− | '''Regime:''' Fault trap<br />

− | :'''Class:''' Normal fault trap
| |
− | :One or more form all or part of lateral closure by sealing the reservoir.
| |
− | ::'''Subclass:''' Tilted fault block
| |
− | ::Block of rock bounded on one or more sides by normal faults. Rotation traps hydrocarbons along edges or in corners.
| |
− | ::'''Subclass:''' Horst
| |
− | ::Block of rock bounded on all sides by normal faults.
| |
− | ::'''Subclass:''' Listric fault trap
| |
− | ::All or part of closure formed by a fault whose plane curves downward and is concave upward.
| |
− | :'''Class:''' Reverse fault trap
| |
− | :One or more faults form all or part of the closure by sealing the reservoir.
| |
− | :'''Class:''' Thrust fault trap
| |
− | :Forms all or part of the closure by sealing the reservoir either laterally or from the top or bottom.

| |
− | ::Forms all or part of the closure by sealing the reservoir laterally or from the top.
