Equatorial Atlantic Conjugate Margins: Comparing Early Stratigraphic Architectures and Depositional Histories

Summary The integrated analysis of seismic profiles, well data and plate reconstructions reveal a wide range of rift and drift phase elements on the conjugate margins between the St Paul and Guinea Fracture Zones. Rifted basement architectures and post-rift sedimentary units are separated by basement highs and former transform margin segments. This analysis focuses on the comparing the early margin geometries and initial passive margin sequences (∼112–65 Ma) between the, once adjoined margins of northern South America and northwest Africa.
