Interplay between base-salt relief, progradational sediment loading and salt tectonics in the Nordkapp Basin, Barents Sea – Part II
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 took pla...

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 took place above a pre-salt basement and basin configuration affected by multiple rift events that influenced the depositional facies and thickness of Pennsylvanian-lower Permian-layered evaporite sequence. Initially, regional mid-late Permian extension reactivated pre-salt Carboniferous faults, caused minor normal faulting in the Permian strata and triggered slight salt mobilization towards structural highs. The main phase of salt mobilization occurred during earliest Triassic when thick and rapidly prograding sediments entered from the east into the Nordkapp Basin. In the early-mid-Triassic, the change in the direction of progradation and sediment entry-points shifted to the NW led to rotation of the earlier-formed mini-basins and shift of dominant salt evacuation direction to the south. The prograding sediment influx direction, sediment transport velocity and thickness influenced the dynamics of the early to late passive diapirism, salt expulsion and depletion along the strike of the basin.
