Overview of Tectonic Subsidence Using the 1D Airy Model in the Dakar Sub-basin Through Backstripping Technique (Senegal, West Africa)

The study investigates the tectonic subsidence history of the MSGBC Basin in Senegal using the 1D Airy backstripping method applied to well GD-1. Results highlight an active post-rift subsidence phase from the Albian to Lower Cenomanian, interrupted by a tecton-thermal uplift event from the Upper Cenomanian to the Lower Conacian. Subsequent slow thermal subsidence reflects lithospheric cooling. The approach provides key insights into the basin’s evolution within the Atlantic opening context, though additional well and seismic data are recommended for broader regional understanding.
