  • Disequilibrium metamorphism of stressed lithosphere 
    Jamtveit, Bjørn; Austrheim, Håkon Olav; Putnis, Andrew (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    Most changes in mineralogy, density, and rheology of the Earth's lithosphere take place by metamorphism, whereby rocks evolve through interactions between minerals and fluids. These changes are coupled with geodynamic ...
  • Localized slip controlled by dehydration embrittlement of partly serpentinized dunites, Leka Ophiolite Complex, Norway 
    Dunkel, Kristina G; Austrheim, Håkon Olav; Renard, Francois; Cordonnier, Benoit; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Dehydration of partly or completely serpentinized ultramafic rocks can increase the pore fluid pressure and induce brittle failure, a process referred to as dehydration embrittlement. However the extents of strain localization ...
  • Subarctic physicochemical weathering of serpentinized peridotite 
    Ulven, Ole Ivar; Beinlich, Andreas; Hövelmann, Jörn-Erik; Austrheim, Håkon Olav; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Frost weathering is effective in arctic and subarctic climate zones where chemical reactions are limited by the reduced availability of liquid water and the prevailing low temperature. However, small scale mineral dissolution ...
