Transform fault

A transform fault is a geological fault that is a special case of strike-slip faulting which terminates abruptly, at both ends, at a major transverse geological feature. Transform faults comprise one of the three types of plate boundaries in plate tectonics. This term was proposed by J.T Wilson in 1965 and he particularly recognised the concept in the case of the tranverse strike-slip faults along which mid-oceanic ridges are off-set. The rock fracture is caused by lateral movement between two tectonic plates. Although formulated in terms of lithospheric plates, transform faults occur naturally in floating ice and are easily reproduced with liquid waxes.
