  • Architecture of growth basins in a tidally influenced, prodelta to delta-front setting: The Triassic succession of Kvalpynten, East Svalbard 
    Smyrak-Sikora, Aleksandra; Osmundsen, Per Terje; Braathen, Alvar; Ogata, Kei; Anell, Ingrid Margareta; Mulrooney, Mark Joseph; Zuchuat, Valentin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    World‐class examples of fault‐controlled growth basins with associated syn‐kinematic sedimentary fill are developed in Upper Triassic prodelta to delta‐front deposits exposed at Kvalpynten, SW Edgeøya in East Svalbard. ...
  • Architecture, deformation style and petrophysical properties of growth fault systems: the Late Triassic deltaic succession of southern Edgeøya (East Svalbard) 
    Ogata, Kei; Mulrooney, Mark; Braathen, Alvar; Maher, Harmon; Osmundsen, Per Terje; Anell, Ingrid Margareta; Smyrak-Sikora, Aleksandra; Balsamo, Fabrizio (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The Late Triassic outcrops on southern Edgeøya, East Svalbard, allow a multiscale study of syn‐sedimentary listric growth faults located in the prodelta region of a regional prograding system. At least three hierarchical ...
  • Complex fault interaction controls continental rifting 
    Naliboff, John B.; Buiter, Susanne; Péron-Pinvidic, Gwenn; Osmundsen, Per Terje; Tetreault, Joya (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Rifted margins mark a transition from continents to oceans and contain in their architecture a record of their rift history. Recent investigations of rift architecture have suggested that multiphase deformation of the crust ...
  • Deep Crustal Flow Within Postorogenic Metamorphic Core Complexes: Insights From the Southern Western Gneiss Region of Norway 
    Wiest, Johannes; Osmundsen, Per Terje; Jacobs, Joachim; Fossen, Haakon (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Viscous crustal flow can exhume once deeply buried rocks in postorogenic metamorphic core complexes (MCCs). While migmatite domes record the flow dynamics of anatectic crust, the mechanics and kinematics of solid‐state ...
  • From Caledonian collapse to North Sea Rift: The extended history of a metamorphic core complex 
    Wiest, Johannes; Wrona, Thilo; Bauck, Marit Stokke; Fossen, Haakon; Gawthorpe, Rob; Osmundsen, Per Terje; Faleide, Jan Inge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Extensional systems evolve through different stages due to changes in the rheological state of the lithosphere. It is crucial to distinguish ductile structures formed before and during rifting, as both cases have important ...
  • Late Devonian–Carboniferous faulting and controlling structures and fabrics in NW Finnmark 
    Koehl, Jean-Baptiste P.; Bergh, Steffen G; Osmundsen, Per Terje; Redfield, Thomas Fitzmaurice; Indrevær, Kjetil; Lea, Halldis; Bergø, Espen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    In the SW Barents Sea, Devonian–Carboniferous collapse led to the formation of major basins and faults, e.g., the Hammerfest Basin bounded by the Troms–Finnmark Fault Complex, and rhomboid- to sigma-shaped (half-)grabens ...
  • Late Paleozoic supradetachment basin configuration in the southwestern Barents Sea — Intrabasement seismic facies of the Fingerdjupet Subbasin 
    Gresseth, Julie Linnea Sehested; Braathen, Alvar; Serck, Christopher Sæbø; Faleide, Jan Inge; Osmundsen, Per Terje (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Late to post-Caledonian, Devonian extension remains unresolved in the SW Barents Sea, despite considerable knowledge from onshore Norway, East Greenland and Svalbard. We analyse intrabasement seismic facies in high-resolution ...
  • Mesozoic-Cenozoic regional stress field evolution in Svalbard 
    Maher, Harmon; Senger, Kim; Braathen, Alvar; Mulrooney, Mark Joseph; Smyrak-Sikora, Aleksandra; Osmundsen, Per Terje; Ogata, Kei (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Cooling fracture orientations in diabase sills associated with the Cretaceous High Arctic Large Igneous Province and syn‐sedimentary Triassic faults help constrain a model for Svalbard's (NE Barents Shelf) Mesozoic stress ...
  • Segmentation of the Caledonian orogenic infrastructure and exhumation of the Western Gneiss Region during transtensional collapse 
    Wiest, Johannes; Jacobs, Joachim; Fossen, Haakon; Ganerød, Morgan; Osmundsen, Per Terje (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The (ultra)high-pressure Western Gneiss Region of the Norwegian Caledonides represents an archetypical orogenic infrastructure of a continent–continent collision zone. To test established exhumation models, we synthesize ...
  • Supradetachment to rift basin transition recorded in continental to marine deposition; Paleogene Bandar Jissah Basin, NE Oman 
    Serck, Christopher Sæbø; Braathen, Alvar; Olaussen, Snorre; Osmundsen, Per Terje; Midtkandal, Ivar; van Yperen, Anna Elisabeth; Indrevær, Kjetil (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    A transition from supradetachment to rift basin signature is recorded in the ~1,500 m thick succession of continental to shallow marine conglomerates, mixed carbonate‐siliciclastic shallow marine sediments and carbonate ...
  • Svalbard Composite Tectono-Sedimentary Element, Barents Sea 
    Olaussen, Snorre; Grundvåg, Sten-Andreas; Senger, Kim; Anell, Ingrid; Betlem, Peter; Birchall, Thomas; Braathen, Alvar; Dallmann, Winfried Kurt; Jochmann, Malte Michel; Johannessen, Erik P.; Lord, Gareth Steven; Mørk, Atle; Osmundsen, Per Terje; Smyrak-Sikora, Aleksandra; Stemmerik, Lars (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The Svalbard Composite Tectono-Stratigraphic Element is located on the north-western corner of the Barents Shelf and comprises a Carboniferous to Pleistocene sedimentary succession. Due to Cenozoic uplift the succession ...
