Inversion of synrift normal faults in the High Atlas Mountains, Morocco

The Leading Edge, 16, 1171-1175, 1997.


Structural inversion related to intracontinental rifting occurs when extensional rift faults reverse their sense of motion during subsequent episodes of compressional tectonics. Features generated by extension, such as half grabens, are uplifted to form positive anticlinal structures.

Key Figures and Captions

Figure 6. Block diagrams based upon structural relationships mapped in the field depicting the effects of pre-existing syn-rift structures upon inversion structures. Two opposing syn-rift half grabens are inverted along existing reactivated faults resulting in two oppositely verging fault-propagation folds.
