Interplay between base‐salt relief, progradational sediment loading and salt tectonics in the Nordkapp Basin, Barents Sea – Part II
Abstract Reprocessed, regional, 2D seismic reflection profiles, 3D seismic volumes and well data (exploration and shallow boreholes), combined with 2D structural restorations and 1D backstripping were used to study the post‐salt evolution of the Nordkapp Basin in Barents Sea. The post‐salt evolution...
