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 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.
The team deployed the AUV Autosub6000 to map anomalies and RUV HyBIS to collect video, visually confirming the site named "Beebe" after William Beebe at a depth of 4,960 m (16,270 ft). [ 1 ] [ 6 ] The vent field was further explored by the NOAAS Okeanos Explorer in 2011, R/V Falkor cruise FK008 and R/V Yokosuka cruise YK13-05 in 2013, and ...
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 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 ...
This site is located on the 110 km long, ultraslow spreading Mid-Cayman Rise within the Cayman Trough. [102] In early 2013, the deepest known hydrothermal vents were discovered in the Caribbean Sea at a depth of almost 5,000 metres (16,000 ft).
The underlying Cayman Ridge is proposed as an uplifted fault block. The oldest rocks are believed to be granodiorite , followed by a cap of basalt . [ 1 ] Situated near the Oriente Transform Fault and the Mid-Cayman Rise, the islands are tectonically active. [ 2 ]
