Abstract
We analyzed an extensive data set of 2D and 3D seismic and well data from the SW Barents Sea, which allowed us to classify the basin margin geometry during the Early Cretaceous. An erosional margin transformed into a progradational margin was identified in areas affected by a Late Jurassic-Early Cretaceous rift event. Long-lived canyons feeding fans were recognized in those types of margin. Furthermore, a progradational margin was interpreted, where large incisions were not recognized, but thin bottomsets interpreted as submarine fans were identified. Additionally, a transition between delta/shoreline scale clinoforms to shelf-slope scale clinoforms was described. Those results have implications for the understanding of the distribution of coarse-grain sediments and for the paleogeography.
