Summary

The North Sea basin is filled by a thick sequence of sediments which are underlain by strongly thinned continental crust. This is commonly attributed to lithospheric stretching (β∼1.5–2.0). An intense stretching is, however, possible only under specific deformation types that do not occur in the North Sea. The geometry of the normal faults ensures extension of only <10–20%.

During the interval from Permian to Cenozoic three rapid phases of subsidence without intense stretching occurred in the North Sea; in each case deeper-water basins were formed (∼0.5 km). The subsidences were caused by the destruction of the lowermost crust by asthenospheric upwelling. Under regional tensile stresses the thinned crust broke into wide blocks (>10 km), these subsided isostatically along normal faults. This was associated with a moderate extension of the basin.
