Fig. 15. Proposed stages in basin development. (A) Stage 1. Areas in southern Norway which are suggested to have acted
as source areas during stage 1. The prograding sequences J-1, J-2 (dark blue) and K-2.1 (red) are marked with proposed
drainage patterns. (B) Stage 2. The carbonates covered most of the North Sea area, including parts of southern Norway in
Late Cretaceous time. However, the extent of the carbonates across southern Norway is uncertain. Note that base of the
Chalk Group thins towards the northern part of the northern North Sea. Southern and western limit of the Chalk Group is
