Fig. 5. Early and Middle Jurassic palaeogeographies of the Norwegian-Greenland Sea rift-system. (A) Hettangian to
Sinemurian (Åre Formation) fluvial plain; (B) Pliensbachian (uppermost Åre Formation & Tilje Formations) embayment;
(C) Toarcian to Aalenian (Ror-Tofte and ile Formations) shelfal strait; and (D) Bajocian to Bathonian (Not-Garn Formations)
rift-structured shelfal strait. Note however that the basin changed back and forth between an unstructured (as shown in B
and C) to a moderately structured (as shown in D) basin during the Toarcian to Bathonian. Modified from Nøttvedt et al .
