The Cote-d\u27Ivoire-Ghana transform margin: preliminary results from ODP leg 159, January-February 1995

Leg ODP 159, devoted to the analysis of the Cote-d\u27Ivoire-Ghana transform margin, has resulted in 13 drill holes in four distinct sites. The sites have documented a sedimentary cover ranging in age from Late Albian to Pleistocene. The cored sediments have recorded the main evolutionary events which participated in the margin construction. Synrift to syntransform siliciclastic sediments were deposited during transform rifting and bear evidence of both extensional and wrench tectonics. Shallow water deposits show an episode of marginal ridge uplift. Final subsequent margin cooling subsidence is also well recorded within the margin cover. -English summar
