  • Basin modelling of a complex rift system: The Northern Vøring Volcanic Margin case example

    Extensional processes can lead to complex crustal configuration depending on the mechanisms of lithospheric thinning and the impact of magmatic additions during rifting and breakup. In this context, we studied the Vøring ...
  • Igneous seismic geomorphology of buried lava fields and coastal escarpments on the Vøring volcanic rifted margin 
    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 ...
  • Magnetotelluric evidence for massive sulphide mineralization in intruded sediments of the outer Vøring Basin, mid-Norway 
    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 ...
  • Magnetotelluric image of a hyper-extended and serpentinized rift system 
    Corseri, Romain; Planke, Sverre; Gelius, Leiv Jacob; Faleide, Jan Inge; Senger, Kim; Abdelmalak, Mohamed Mansour (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Magnetotelluric (MT) data can image the Earth's electrical resistivity down to the mantle but are rarely used for investigation of offshore rifted margins. In such settings, the lower crust and upper mantle are altered by ...
  • New insights into the late Mesozoic-Cenozoic tectono-stratigraphic evolution of the northern Lofoten-Vesterålen margin, offshore Norway 
    Meza Cala, Juan Camilo; Tsikalas, Filippos; Faleide, Jan Inge; Abdelmalak, Mohamed Mansour (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    2D multi-channel seismic profiles and a 3D seismic survey were utilised together with potential field and available well data to study the late Mesozoic-Cenozoic tectono-stratigraphic evolution of the northern Lofoten-Vesterålen ...
  • Paleobathymetric reconstructions of the SW Barents Seaway and their implications for Atlantic–Arctic ocean circulation 
    Lasabuda, Amando P. E.; Hanssen, Alfred; Laberg, Jan Sverre; Faleide, Jan Inge; Patton, Henry; Abdelmalak, Mohamed Mansour; Rydningen, Tom Arne; Kjølhamar, Bent (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Unravelling past, large-scale ocean circulation patterns is crucial for deciphering the longterm global paleoclimate. Here we apply numerical modelling to reconstruct the detailed paleobathymetry-topography of the southwestern ...
  • Quantification and restoration of the pre‐drift extension across the NE Atlantic conjugate margins during the mid‐Permian‐early Cenozoic multi‐rifting phases 
    Abdelmalak, Mohamed Mansour; Gac, Sebastien; Faleide, Jan Inge; Shephard, Grace; Tsikalas, Filippos; Polteau, Stephane; Zastrozhnov, Dmitry; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    The formation of the NE Atlantic conjugate margins is the result of multiple rifting phases spanning from the Late Paleozoic and culminating in the early Eocene when breakup was accompanied with intense magmatic activity. ...
  • Seismic volcanostratigraphy of the NE Greenland continental margin 
    Geissler, Wolfram H.; Gaina, Carmen; Hopper, John R.; Funck, Thomas; Blischke, Anett; Árting, Uni Egholm; Á Horni, Jim; Péron-Pinvidic, Gwenn; Abdelmalak, Mohamed Mansour (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The Early Eocene continental break-up between the NE Greenland and the mid-Norwegian–SW Barents Sea margins was associated with voluminous magmatism and led to the emplacement of massive volcanic complexes including wedges ...
  • Structural analysis and measured extension in fault complexes along the Lofoten-Vesterålen margin, offshore Norway, in the context of crustal-scale rifting towards breakup in NE Atlantic 
    Meza Cala, Juan Camilo; Tsikalas, Filippos; Abdelmalak, Mohamed Mansour; Faleide, Jan Inge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract Late Cretaceous–Palaeocene continental extension within the Lofoten‐Vesterålen margin is investigated by integrating 2D‐3D seismic and potential field datasets, together with updated crustal transects. Most of ...
