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] A transform fault is a special case of a strike-slip fault that also forms a plate boundary.
When these are drawn onto the diagram containing the velocity triangle these lines must be able to meet at a single point, for the triple junction to exist stably. These lines necessarily are parallel to the plate boundaries as to remain on the plate boundaries the observer must either move along the plate boundary or remain stationary on it.
The Australian plate (previous to 3 million years ago the Indo-Australian plate) and Pacific plate boundary is the most complex boundary of the Macquarie triple junction region, due to the unique collision of the two plates creating two convergent boundaries separated by a transform boundary.
A special class of strike-slip fault is the transform fault when it forms a plate boundary. This class is related to an offset in a spreading center, such as a mid-ocean ridge, or, less common, within continental lithosphere, such as the Dead Sea Transform in the Middle East or the Alpine Fault in New Zealand. Transform faults are also referred ...
Oceanic crust age differences and ridge-ridge transform faulting associated with offset mid-ocean ridge segments lead to the formation of fracture zones. A fracture zone is a linear feature on the ocean floor—often hundreds, even thousands of kilometers long—resulting from the action of offset mid-ocean ridge axis segments.
The accumulated stress in transform fault zones is released during strike-slip earthquakes. The transform fault is induced by strike-slip motion that is transverse to the fault zone. The blocks between the faults are slightly rotated afterwards. A diagram (fig.2) is shown to illustrate this phenomenon.
The junction of the Queen Charlotte, Fairweather, and Transition faults is located at the southeastern tip of the Yakutat block, an oceanic plateau and microplate. [8] The southern boundary of the QCF is marked by the complex Pacific–North American–Explorer triple junction off the coast of southern British Columbia. [8]
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] Additionally, this area has been called the Aden–Owen–Carlsberg triple junction , although the Carlsberg Ridge is offset 330 km (210 mi) from the point where the Owen fracture zone/fault ...
