Structure de la marge continentale norvégienne au débouché de la mer de Barentz

Reconstructions of the continents prior to the opening of the Norwegian sea indicate an overlap between the Greenland and the Norwegian continental margins just west of the Barentz sea and imply that the basement of this area is of oceanic origin. Seismic profiling shows an oceanic-type basement covered by thick Tertiary sediments. The sedimentary supply is related to the geological history of the Barentz sea where only little unconsolidated sediments are known. Further south the structures of the present margin are directly related to the early opening of the Norwegian sea. [NOT CONTROLLED OCR]
