Some fracture zones such as Chile and Valdivia make up large sections of the Nazca-Antarctic plate boundary. Map of the Chile Rise and its fracture zones in Nazca and the Antarctic plates Active Pacific Ocean fracture zones are perpendicular to the mid-ocean ridges (black lines) in orange shaded region. Since the map was prepared ages not shown ...
The data is incomplete as official recognition of feature names is a drawn out process. Unofficial names have been added from academic literature and this remains a work in progress particularly for Indian Ocean and Eastern Pacific where a number of officially unnamed fracture zones exist and mapping is still ongoing.
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]

Geelvink Channel is a feature to the east of the Houtman Abrolhos in the Indian Ocean off the coast of Western Australia, that lies between the Abrolhos and the port of Geraldton. [ 1 ] It is a feature that has whale movements and oil and gas exploration researched for effects of seismic exploration methods.
Separating the African (or Nubian–Somali plates) and Antarctic plates, the Southwest Indian Ridge (SWIR) stretches 7,700 km (4,800 mi) from the Atlantic Ocean to the Indian Ocean. With an average spreading rate of 14–15 millimetres per year (0.55–0.59 in/year), the SWIR is one of the slowest-spreading mid-ocean ridges on Earth.
The Owen fracture zone, together with the Dalrymple Trough in its northern end, is a transform fault along which spreading between the Arabian and Indian plates at the Carlsberg Ridge becomes the subduction of the Himalayan orogeny. The Owen fracture zone passes east of the Owen Ridge which was uplifted during the opening of the eastern Gulf of ...
Figure 1: The present Macquarie triple junction portrays the three most common oceanic tectonic boundaries. The first is Emerald Fracture Zone, a leaky transform fault, which is the region between A and A'. The second is the Southeast Indian Ridge, located just west of the MTJ and is split by the Balleny Fault Zone, identified by the letter B.
