Malpelo Ridge Explained

The Malpelo Ridge (Spanish; Castilian: Dorsal de Malpelo) is an elevated part of Nazca Plate off the Pacific coast of Colombia. It is a faulted chain of volcanic rock of tholeiitic composition.^[1] The Malpelo Ridge may have originated simultaneously as Carnegie Ridge, and thus represent an old continuation of Cocos Ridge.^[2] It is thought to have acquired it present position due to tectonic movements along the Panama Fracture Zone.^[2]
