Three-dimensional seismic reflection data from the Egersund Basin, offshore Norway image geomorphological features that record
mid-Permian footwall degradation of basin-bounding fault systems. This ancient landscape was subsequently flooded during the
pan-European, Late Permian transgression of the North Permian Salt Basin and was fossilized beneath Zechstein Supergroup evaporites.
We provide the first conclusive evidence for pre-Zechstein normal faulting in the Egersund Basin, indicating that extensional
strain was shared between Permian and Late Jurassic–Early Cretaceous rift events.
