Wrench-fault tectonics

John Drummond Moody and Melvin James Hill
Wrench-fault tectonics
Bulletin of the Geological Society of America (September 1956) 67 (9): 1207-1246


Extending the work of E. M. Anderson, M. K. Hubbert, and W. Hafner on faulting, the authors develop the hypothesis that anticlinal folds, thrust faults, and wrench faults can be generated as a result of movement on a large wrench fault such as the San Andreas of California. Extension of this concept leads to the conclusion that for any given tectonic area, at least eight directions of wrench faulting and four directions of anticlinal folding and/or thrusting should accommodate the structural elements of that region; these directions should have a more or less symmetrical disposition relative to the direction of the primary compressive stress. The angles alpha , beta , and gamma are defined to describe the geometry of such a wrench-fault tectonic system relatively completely.
