The Norwegian Sea continental margin is dominated by the deep-water Vøring and Møre basins, which contain thick Cretaceous and Tertiary fills. To the east lie the Halten Terrace, Nordland Ridge and Trøndelag Platform, with a cover of Triassic, Jurassic and Cretaceous sediments. To the west, the Vøring and Møre Marginal Highs are overlain by a thick pile of early Tertiary lavas.
