The structural style of the African Atlantic margin shows significant differences between the passive rifted Northwest African Atlantic Margin (offshore Senegal, Gambia, Guinea Bissau and Guinea) and the West African Transform Margin (from Sierra Leone to Benin). Recently acquired seismic data provides good quality imaging (down to the Moho in deepwater areas) that allows an understanding of the structural development since the initiation of the opening of the Atlantic Ocean at the end of the Jurassic and gives insights into the present day structural styles and how they developed.
