Geological examples of oblique-slip normal faults from Australia, Asia, and North America have similar secondary deformation patterns as those in the experimental models.  The northwestern margin of the Dampier sub-basin, Northwest Shelf, Australia, is a broad extensional forced fold.  The fold affects the sedimentary cover above a deep-seated, oblique-slip normal fault zone.  The extensional forced fold is dissected by numerous secondary normal faults.  Some of these faults strike NE-SW, parallel to the rift-basin trend.  Most of these faults, however, strike NNE-SSW, oblique to the rift-basin trend.  The Mexia-Talco fault zone forms the boundary of the East Texas basin.  The detached normal faults within this fault zone developed near the updip limit of the Jurassic Louann Salt.  Faults in the Mexia-Talco fault zone trend either subperpendicular to the displacement direction of the flowing Louann Salt or subparallel to the updip limit of the salt.  Examples from southeast Asia and from the Fundy rift basin of southeastern Canada also have two distinct fault populations. In summary, oblique-slip fault zones, regardless of whether they involve the basement or detach within salt or shale, have two distinct fault populations that typically cut a broad extensional forced fold.
