dc.description.abstract2D satellite gravity modeling constrained by a 2D seismic profile allowed geophysical mapping of five Cretaceous–Holocene sedimentary units in the Tanga Basin. The mapping of these units was based on density differences between intervals constrained by horizons from seismic interpretation. Chronologically, these units are the Lower Cretaceous and older, Upper Cretaceous–Paleocene, Eocene–Oligocene, Miocene–Pliocene, and the Quaternary intervals. Depth estimates based on Werner solutions derived from Bouguer gravity anomaly show that these units contain thick sedimentary successions with potential source and reservoir rocks for petroleum generation and accommodation, respectively. A combination of aeromagnetic and gravity data revealed the possible presence of magmatic intrusions in the study area. Structural mapping revealed the presence of at least four sub-basins in the study area. These sub-basins are bounded by major faults and dissected by several other minor faults which reach the sea bottom. The bounding faults for these sub-basins controlled the sedimentary development of the Tanga Basin. The revealed sub-basins have several structural lows interpreted as potential areas where source rocks may be present.en_US
