  • Dalslåen, Bjørgunn Heggem; Gasser, Deta; Grenne, Tor; Augland, Lars Eivind; Andresen, Arild (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
    The late Neoproterozoic–Paleozoic Iapetus Ocean developed between Laurentia, Baltica, Siberia and Gondwana. Its Paleozoic closure history is recorded by volcano-sedimentary successions within the Caledonian orogen of ...
  • Koehl, Jean-Baptiste P. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    The present study of field, petrological, exploration well, and seismic data describes backward-dipping duplexes comprised of phyllitic coal and bedding-parallel décollements and thrusts localized along lithological ...
  • Indrevær, Kjetil; Gabrielsen, Roy Helge; Faleide, Jan Inge (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Tectonic inversion of rift basins is most commonly reported in the literature to occur after rifting has ceased. In contrast, we present evidence for synrift, localized tectonic inversion from the Loppa High area, southwestern ...
  • Bjørlykke, Knut (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    The Norwegian government and also the universities were unprepared for an offshore oil province. Very little information about the offshore geology was then available due to the thick cover of Quaternary and Tertiary ...
  • Domeier, Mathew (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Asia is key to a richer understanding of many important lithospheric processes such as crustal growth, continental evolution and orogenesis. But to properly decipher the secrets Asia holds, a first-order tectonic context ...
  • Torsvik, Trond Helge; Steinberger, Bernhard; Ashwal, Lewis D.; Doubrovine, Pavel; Trønnes, Reidar G (Journal article / Tidsskriftartikkel / SubmittedVersion, 2016)
    Kevin Burke’s original and thought-provoking contributions have been published steadily for the past 60 years, and more than a decade ago he set out to resolve how plate tectonics and mantle plumes interact by proposing a ...
  • Campbell, Lucy; Menegon, Luca; Pennacchioni, Giorgio; Fagereng, Åke (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Deep intracontinental earthquakes are poorly understood, despite their potential to cause significant destruction. Although lower crustal strength is currently a topic of debate, dry lower continental crust may be strong ...
  • Jamtveit, Bjørn; Ben-Zion, Yehuda; Renard, Francois; Austrheim, Håkon Olaf (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    The structural and metamorphic evolution of the lower crust has direct effects on the lithospheric response to plate tectonic processes involved in orogeny, including subsidence of sedimentary basins, stability of deep ...
  • Ferre, Eric C.; Meado, Andrea L; Geissman, John W; Di Toro, Giulio; Spagnuolo, Elena; Ueda, Tadamasa; Ashwal, Lewis D.; Deseta, Natalie; Andersen, Torgeir Bjørge; Filiberto, Justin; Conder, James A (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Ultramafic pseudotachylytes have been regarded as earthquake fossils formed at mantle depths (i.e., >30 km). Here we show that pseudotachylytes hosted by ultramafic rocks from three localities have distinct magnetic ...

  • Halpaap, Felix; Rondenay, Stéphane; Perrin, Alexander; Goes, Saskia; Ottemöller, Lars; Austrheim, Håkon; Shaw, Robert; Eeken, Thomas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Subducting plates release fluids as they plunge into Earth’s mantle and occasionally rupture to produce intraslab earthquakes. It is debated whether fluids and earthquakes are directly related. By combining seismic ...
  • Nasipuri, Pritam; Corfu, Fernando; Bhattacharya, A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    There is consensus that, at 1.0–0.9 Ga, the granulites in the Eastern Ghats Province (EGP), Eastern India, and the Rayner Complex, Antarctica, were parts of a coherently evolved crustal block. Paleogeographic reconstructions ...
  • Phillips, Peter C. B.; Leirvik, Thomas; Storelvmo, Trude (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    How sensitive is Earth’s climate to a given increase in atmospheric greenhouse gas (GHG) concentrations? This long-standing question in climate science was recently analyzed by dynamic panel data methods using extensive ...
  • Trodahl, Marta (Master thesis / Masteroppgave, 2015)
    The advent of satelitte observations revolutionalized Oceanography, and it has unveiled a turbulent ocean circulation dominated by mesoscale eddies (10-100km). Eddies represent an important aspect of the flow, and understanding ...
  • Hattermann, Tore; Isachsen, Pål Erik; von Appen, Wilken-Jon; Albretsen, Jon; Sundfjord, Arild (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Eddy‐resolving regional ocean model results in conjunction with synthetic float trajectories and observations provide new insights into the recirculation of the Atlantic Water (AW) in Fram Strait that significantly impacts ...
  • Romans, Brian W; Fosdick, Julie C; Poyatos More, Miquel; Helland-Hansen, William (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
  • Plach, Andreas; Nisancioglu, Kerim Hestnes; Langebroek, Petra; Born, Andreas; Le clec'h, Sebastien (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    The Greenland ice sheet contributes increasingly to global sea level rise. Its history during past warm intervals is a valuable reference for future sea level projections. We present ice sheet simulations for the Eemian ...
