The relatively narrow trough trends east-northeast to west-southwest and has a maximum depth of 7,686 metres (25,217 ft). Within the trough is a slowly spreading north–south ridge which may be the result of an offset or gap of approximately 420 kilometres (260 mi) along the main fault trace.
The Beebe vent field was initially detected in October 2009 by CTD, Eh, and optical backscatter anomalies in the water column above the Mid-Cayman Rise aboard the R/V Cape Hatteras. [ 3 ] [ 4 ] The team deployed HROV Nereus to conduct surveys which identified a double hydrothermal plume at 3,900 metres (12,800 ft) and 4,250 m (13,940 ft) deep ...
A bathymetry map of the Mount Dent ocean core complex. The Von Damm vent field is located centrally on the Mid-Cayman Rise between the Oriente and Swan Island transform faults. [ 5 ] The ocean core complex, which the field resides on the eastern side of, is known as Mount Dent and is the most central of the three known on the spreading center.
The formation of the Cayman Trough produced the last significant tectonic feature on the islands after 39 million years ago, with sinistral strike-slip faults. A structural block produced as a result creates a 5.7 kilometer sinistrally offset contact between the Water Island and Louisenhoj formations. [1]
The location of the Mid-Cayman Rise. The Mid-Cayman Rise or Mid-Cayman Spreading Center is a relatively short (110 km long) divergent plate boundary in the middle of the Cayman Trough. It forms part of a dominantly transform boundary that is part of the southern margin to the North American Plate. It is an ultra-slow spreading center where the ...
The Cayman Ridge is an undersea mountain range on the northern margin of the Cayman Trough in the Caribbean Sea. It extends from the Sierra Maestra in the east to the Misteriosa Bank and Rosario Bank in the west, a distance of about 1,500 km (930 mi). The Cayman Ridge also includes the Cayman Islands. [1]
Additionally, the Cayman Trough, which is a pull-apart basin within a transform fault zone, [10] is not an oceanic trench. Trenches, along with volcanic arcs and Wadati–Benioff zones (zones of earthquakes under a volcanic arc) are diagnostic of convergent plate boundaries and their deeper manifestations, subduction zones .
Satellite image of the Cayman Trough Bathymetric features of the Rockall Trough northwest of Scotland and Ireland. In geology, a trough is a linear structural depression that extends laterally over a distance. Although it is less steep than a trench, a trough can be a narrow basin or a geologic rift. These features often form at the rim of ...
