Spatio-temporal evolution and paleogeographic reconstructions along rifted margins result from the integration of structural architecture based on magnetics, gravity and log offset 2D seismic, in addition to source-to-sink models based on 3D seismic, well logs, cores, and provenance studies. However, sedimentary records of early rift phases are commonly incomplete due to uplift and erosion, poor preservation due to subsequent deformation and burial, or simply data availability. This research project investigates rift initiation along the Norwegian Continental Margin in two successive time intervals including the Permo-Triassic and Upper Triassic-Lower Jurassic. Detailed tectono-stratigraphic evolution of the Permo-Triassic rifting, including the re-activation of deep inherited structures and the deposition of the Triassic salt has played an important role in controlling the basin morphology and associated depositional systems during the Upper Triassic-Lower Jurassic. Regional, high-resolution seismic tectono-stratigraphy and seismic geomorphology studies are instrumental in developing data-driven models within a regional context. They bring new insights into paleogeographic reconstruction during rift initiation. This holistic approach not only fills the gaps left by incomplete sedimentary records but also offers a predictive framework for future exploration and development.
