A transform fault or transform boundary, is a fault along a plate boundary where the motion is predominantly horizontal. [1] It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone . [ 2 ]
Globally most fault zones are located on divergent plate boundaries on oceanic crust. This means that they are located around mid-ocean ridges and trend perpendicular to them. The term fracture zone is used almost exclusively for features on oceanic crust ; similar structures on continental crust are instead termed transform or strike slip faults .

At the triple junction each of the three boundaries will be one of three types – a ridge (R), trench (T) or transform fault (F) – and triple junctions can be described according to the types of plate margin that meet at them (e.g. fault–fault–trench, ridge–ridge–ridge, or abbreviated F-F-T, R-R-R).
A leaky transform fault is a transform fault with volcanic activity along a significant portion of its length producing new crust. [1] In addition to the regular strike-slip motion observed at transform boundaries, an oblique extensional component is present, resulting in motion of the plates that is not parallel to the plate boundary.
Slip along the Owen fracture zone is occurring at 2 mm (0.079 in)/yr, the slowest rate on Earth, which means the Arabian plate moves northward faster than the Indian plate (4 vs. 2 mm/yr). [2] In some usages, the name Owen Transform Fault is used to denote the short section between the end of the Aden-Sheba ridge and the Carlsberg Ridge. [3]
The Azores–Gibraltar transform fault (AGFZ), also called a fault zone and a fracture zone, is a major seismic zone in the eastern Atlantic Ocean between the Azores and the Strait of Gibraltar. It is the product of the complex interaction between the African , Eurasian , and Iberian plates. [ 1 ]
A transfer zone in geology is an area where deformational strain is transferred from one structural element to another typically from fault to fault in rift systems. . Therefore, listric faults and monoclinal folds in the hanging wall are typical structures linked by transfer zones; however, complexitie
