  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Plach, Andreas; Nisancioglu, Kerim Hestnes; Le clec'h, Sebastien; Born, Andreas; Langebroek, Petra; Guo, Chuncheng; Imhof, Michael; Stocker, Thomas F. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Understanding the behavior of the Greenland ice sheet in a warmer climate, and particularly its surface mass balance (SMB), is important for assessing Greenland’s potential contribution to future sea level rise. The Eemian ...
  • Sperrevik, Ann Kristin (Master thesis / Masteroppgave, 2008)
    As global warming causes both glaciers and sea ice to decay, increased freshwater flux into the North Atlantic is expected. In addition precipitation at high latitudes is predicted to increase under global warming as well, ...
  • Nooraiepour, Mohammad; Bohloli, Bahman; Park, Joonsang; Sauvin, Guillaume; Skurtveit, Elin; Mondol, Nazmul Haque (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Fracture networks inside geological CO2 storage reservoirs can serve as primary fluid flow conduit, particularly in low-permeability formations. While some experiments focused on the geophysical properties of brine- and ...
  • Nooraiepour, Mohammad; Fazeli, Hossein; Miri, Rohaldin; Hellevang, Helge (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Fracture networks inside the caprock for CO2 storage reservoirs may serve as leakage pathways. Fluid flow through fractured caprocks and bypass conduits, however, can be restrained or diminished by mineral precipitations. ...
  • Kalani, Mohsen; Zadeh, Mohammad Koochak; Jahren, Jens; Mondol, Nazmul Haque; Faleide, Jan Inge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Pore pressure in fine-grained rocks is important with respect to drilling problems such as kicks, blowouts, borehole instability, stuck pipe and lost circulation. In this study, a succession of overpressured, fine-grained, ...
  • Fazeli, Hossein; Hellevang, Helge; Patel, Ravi A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Fractures are the main flow path in rocks with very low permeability, and their hydrodynamic properties might change due to interaction with the pore fluid or injected fluid. Existence of minerals with different reactivities ...
  • Prieur, Nils Charles; Rolf, Tobias; Luther, Robert; Wunnemann, Kai; Xiao, Zhiyong; Werner, Stephanie C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The effects of the coefficient of friction and porosity on impact cratering are not sufficiently considered in scaling laws that predict the crater size from a known impactor size, velocity, and mass. We carried out a ...
  • Michalsen, Martin Aleksander (Master thesis / Masteroppgave, 2018)
    Dynamical runout models are essential tools in landslide hazard and risk assessment, because they allow us to simulate the motion of past landslides and to predict the motion of future landslides. Runout distances obtained ...
  • Matapour, Zagros (Master thesis / Masteroppgave, 2013)
    The Barents Sea petroleum system contains multiple source rock intervals, with hydrocarbon generation having occurred over a long geological time. As such the area possibly represents an overfilled petroleum system. Still, ...
