Thermal Evolution and Subsidence of Eastern Parts of Niger Delta Sedimentary Basin, Nigeria

Abstract: The thermal evolution and subsidence of the eastern Niger Delta have been obtained from the similarity solution of a simple cooling model of ocean lithosphere. The result shows that the subsidence of the basin resulted from the thermal contraction of the lithosphere and sediment deposition started in the Eocene (about 60 million years ago till date). The results show that the thermal subsidence varies directly as the square root of time, . The maximum thickness of the sediment is approximately 9 to 12 Km. Comparison of the model result with the biostratigraphy of oil well in the study area shows that the model depth and age of sedimentary layers are the same as that obtained from biostratigraphy . The model is simple and can be applied to other similar basins.

Keywords: Basin, Niger Delta, Sediment deposition, Subsidence, Thermal evolution.
