Fig. 4. Lithostratigraphic and seismic stratigraphic scheme in the northern North Sea, Norwegian-Danish Basin and Central
Graben. The seismic sequences are correlated to previous work. Arrows show direction of progradation and aggradation.
VG = Viking Graben, ÅG = Åsta Graben, EB = Egersund Basin, NHP = northern Horda Platform, DNS = Danish North Sea,
OD = onshore Denmark, NS = Norwegian Sea, CNS = Central North Sea. Lithostratigraphy is from Deegan & Scull (1977),
Eidvin et al . (2007), Schiøler et al . (2007) and Rasmussen et al . (2010).

In this work we propose that the study area has
experienced four major changes in basin configu-
ration in late Mesozoic and Cenozoic time. The
four basin configurations are based on different
basin infill patterns and basin geometry, including

width, depth and orientation. These are the Late
Jurassic to Early Cretaceous (basin configuration 1),
Late Cretaceous (basin configuration 2), Early
Palaeogene (basin configuration 3) and Late
Palaeogene to Pleistocene (basin configuration 4).
