Abstract

The east-west Guinea fracture zone is situated off Sierra Leone, West Africa. The estimated topographic left lateral displacement is about 230 kilometers. This fracture zone is the eastern analog of the Vema fracture zone, with its associated troughs, and of the Barracuda Fault. The Guinea fracture zone marks the northern boundary on the African coast of a wide zone of left lateral shear in the equatorial Atlantic.
