Flexure of the lithosphere and the geodynamical evolution of non-cylindrical rifted passive margins: Results from a numerical model incorporating variable elastic thickness, surface processes and 3D thermal subsidence

► New flexural model that includes variable effective elastic thickness, a surface process model and a 3D thermal model ► Model is fully tested and calibrated. ► Model is used to simulate complex 3D stratigraphic architecture of a passive margin. ► Results are compared to observations from the Western African margin.
