f A Multidisciplinary Study of a Typical Transform Continental Margin: The Ghana - Cote d'Ivore Margin Segment

The continental margin off eastern Cote d'Ivoire and Ghana results from a major transform motion between the African and south American plates during early Cretaceous times. Today the transform motion is still active along the Romanche fracture zone, which offsets the Equatorial Mid Atlantic Ridge by a little less than 1000 km. Since its creation this transform margin segment has not experimented any major regional tectonic reorganization and its present day sedimentary, tectonic and crustal characteristics are directly inherited from its early transform history. Therefore we have investigated this area of the eastern equatorial Atlantic since more than 10 years thanks to a set of available marine geological/geophysical tools.
