Evidence for a More Complex Crustal Setting Offshore Gabon: Support from a High-Resolution Regional Seismic Dataset Integrated with 3D Grav/Mag Modeling

A high-resolution regional seismic, gravity and magnetics dataset was acquired offshore southern Gabon, which allowed an in-depth and integrated approach for analyzing the crustal setting in this area. Detailed analysis of the datasets available, and 3D modeling of the crust over this region, suggests that a more complex crustal setting than previously discussed in papers using either long offset 2D seismic, or detailed prospect scale 3D seismic datasets. Placing this information into the framework of the mega-regional publicly available gravity and magnetic datasets provides insights into the possible relationships between the changing upper and lower plate crustal settings experienced at different times in this area.
