Possible structural link between yucatan and cuba

Oceanographic investigations along the eastern margin of the Yucatan Peninsula (Quintana Roo Territory) have revealed the presence of two ridges separated by a depression, which parallel the Yucatan coast. The strike of the eastern, or Outer Ridge (north-northeast) changes to northeast at the northern end of this ridge and reaches toward the Cuban shelf. The origin of the Outer Ridge is unknown, but possibly it is a remnant of a Paleozoic fold belt that connects the basement rocks beneath the ridge east of British Honduras (Turneffe Island well) with basement rocks on the Isle of Pines (Cuba).
