Tectonics of the Wolf Creek Fault Zone, southern Illinois: A consequence of Late Paleozoic transpression and transtension at the southeastern end of the Ste. Genevieve Fault System
… the SGFS produced shortening structures. Later, transtension associated with right-lateral strike-slip produced an extensional pull-apart zone. Similar episodes of deformation have been found in other continental-interior fault-and-fold zones (e.g., the Cottage Grove Fault System and the Sandwich …

The growth of fractures in the Earth
… Fracture growth under simple shear and under transtension occurs by a kink and along a smooth, slightly convex trajectory; the computed path is almost identical to the one obtained in the laboratory. Under transpression, fracture also grows by a kink and along a smooth trajectory which is of …

The structural and engineering geology of the Country Rock at Finsch Mine
… structural/tectonic history is suggested whereby transtension is followed by a rotation of the tectonic stress vectors with resultant transpression. During transpression the fault-parallel jointing/cleavage is fanned by fault-parallel folds and a conjugate set of joints form as a result of WSW …

Karoo-Etendeka Unconformities in NW Namibia and their Tectonic Implications
… Etjo Formation in its associated pull-apart and transtension structures. A locally well developed angular unconformity defines a hiatus between the two formations. Correlation with the main Karoo Basin in South Africa confirms that this gap is of a regional extent and not only a local, fault …

Structure of the Patagonian fold-thrust belt in the Magallanes region of Chile, 53° - 55° S Lat.
… and record a tectonic event defined by sinistral transtension that probably reflects changing plate dynamics associated with the opening of the Drake Passage during the Early Miocene.
