1. n. [Geology]

The simultaneous occurrence of strike-slip faulting and compression, or convergence, of the Earth's crust. In areas of transpression, rocks can be faulted upward to form a positive flower structure. Areas of strike-slip faulting in rifting or diverging crust are experiencing transtension, in which rocks can drop down to form a negative flower structure.
