Geography of the Cayman Islands

The Cayman Rise extends from southeastern Cuba along the northern margin of the Cayman Trough toward Costa Rica and resulted from Paleocene to Eocene island arc formation with associated volcanism along an extinct subduction zone.

Lanalhue Fault

South of Lanalhue Fault most of the Chilean Coast Range is an accretionary wedge formed by at least since the Paleozoic along the subduction zone at South Americas western margin.

Troodos Ophiolite

Along with the alkaline character of the plagiogranites it can be assumed that the spreading ridge of the Troodos was situated above a subduction zone, but the mantle from which lavas were extruded was that of mantle that had recently lost a melt fraction.
