    The mid-Norwegian margin is regarded as an example of a volcanic-rifted margin, formed prior to and during, Paleogene breakup of the northeast Atlantic. The area is characterized by the presence of voluminous basaltic ...
  • Tegner, Christian; Andersen, Torgeir Bjørge; Kjøll, Hans Jørgen; Brown, Eric L.; Hagen-Peter, Graham; Corfu, Fernando; Planke, Sverre; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Abstract The origin of Large Igneous Provinces (LIPs) associated with continental breakup and the reconstruction of continents older than c. 320 million years (pre-Pangea) are contentious research problems. Here we study ...
  • Mazzini, Adriano; Svensen, Henrik; Forsberg, Carl Fredrik; Linge, Henriette; Lauritzen, Stein-Erik; Haflidason, Haflidi; Hammer, Øyvind; Planke, Sverre; Tjelta, Tor-Inge (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Pockmarks are seafloor craters usually formed during methane release on continental margins. However, the mechanisms behind their formation and dynamics remain elusive. Here we report detailed investigations on one of the ...
  • Jones, Morgan Thomas; Augland, Lars Eivind; Shephard, Grace; Burgess, Seth; Eliassen, Gauti Trygvason; Jochmann, Malte; Friis, Bjarki; Jerram, Dougal Alexander; Planke, Sverre; Svensen, Henrik (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Radioisotopic dating of volcanic minerals is a powerful method for establishing absolute time constraints in sedimentary basins, which improves our understanding of the chronostratigraphy and evolution of basin processes. ...
  • Corseri, Romain; Faleide, Thea Sveva; Faleide, Jan Inge; Midtkandal, Ivar; Serck, Christopher Sæbø; Trulsvik, Mikal; Planke, Sverre (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Mud-rich prograding sediment lobes make for most of the Barremian – Albian stratigraphic record in the SW Barents Sea. Submarine canyons and channels potentially represent key components of sediment transport from shelf ...
  • Karstens, Jens; Haflidason, Haflidi; Becker, Lukas; Berndt, Christian; Rüpke, Lars Helmuth; Planke, Sverre; Liebetrau, Volker; Schmidt, Markus; Mienert, Jurgen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Large amounts of methane are stored in continental margins as gas hydrates. They are stable under high pressure and low temperature, but react sensitively to environmental changes. Bottom water temperature and sea level ...
  • Svensen, Henrik; Torsvik, Trond Helge; Callegaro, Sara; Augland, Lars Eivind; Heimdal, Thea Hatlen; Jerram, Dougal Alexander; Planke, Sverre; Pereira, Egberto (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Gondwana was an enormous supertarrane. At its peak, it represented a landmass of about 100 × 106 km2 in size, corresponding to approximately 64% of all land areas today. Gondwana assembled in the Middle Cambrian, merged ...
  • Reynolds, P.; Planke, Sverre; Millett, J.M.; Jerram, Dougal Alexander; Trulsvik, M.; Schofield, N.; Myklebust, R. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Continental rifting is often associated with voluminous magmatism and perturbations in the Earth's climate. In this study, we use 2D seismic data from the northeast Greenland margin to document two Paleogene-aged sill ...
  • Planke, Sverre; Millett, John M; Maharjan, Dwarika; Jerram, Dougal Alexander; Abdelmalak, Mohamed Mansour; Groth, Audun; Hoffmann, Jasper; Berndt, Christian; Myklebust, Reidun (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Voluminous igneous complexes are commonly present in sedimentary basins on volcanic rifted margins, and they represent a challenge for petroleum explorationists. A 2500 km2 industry-standard 3D seismic cube has recently ...
  • Angkasa, Syahreza Saidina; Jerram, Dougal Alexander; Millett, John M; Svensen, Henrik; Planke, Sverre; Taylor, Ross A; Schofield, Nick; Howell, John (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The emplacement of large intrusive complexes into sedimentary basins can have profound effects on host sedimentary rocks including deformation, thermal aureole metamorphic reactions, alteration of fluid-flow pathways, and ...
  • Corseri, Romain; Senger, Kim; Selway, Katherine; Abdelmalak, Mohamed Mansour; Planke, Sverre; Jerram, Dougal Alexander (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    A highly conductive body (0.1–0.8 Ω·m) is identified at mid-crustal depth (8–13 km) in the north Gjallar Ridge from magnetotelluric (MT) data and further investigated in light of other remote-sensing geophysical data ...

    The emplacement of igneous intrusions into sedimentary basins mechanically deforms the host rocks and causes hydrocarbon maturation. Existing models of host-rock deformation are investigated using high-quality 3D seismic ...
  • Iyer, Karthik Herman; Schmid, Daniel Walter; Planke, Sverre; Millett, John (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Vent structures are intimately associated with sill intrusions in sedimentary basins globally and are thought to have been formed contemporaneously due to overpressure generated by gas generation during thermogenic breakdown ...
