Transpression

In geology, transpression is a type of strike-slip deformation that deviates from simple shear because of a simultaneous component of shortening perpendicular to the fault plane.

Commonly developed features include transposition foliations, lineations, stylolites, folds, and reverse faults.

The complete geometry presented by all structural elements in the zone is used to constrain the actual boundary displacements.

As seen in deeply eroded outcrop exposures or from subsurface geophysical surveys, restraining bends commonly define positive flower structures.

Restraining bends are widespread on the Earth's surface, from sub-outcrop-scale examples to large scale mountain ranges.

Simple model for transpression : strike-slip zone with an additional and simultaneous shortening across the zone. Also induces vertical uplift.
