  • 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 ...
  • Zheng, Xiaojiao; Cordonnier, Benoit; Zhu, Wenlu; Renard, Francois; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Hydration of a nominally dry rock can cause expansion of the solid volume, resulting in reaction‐induced fracturing and an associated increase in the porosity and permeability of the rock. We study the effect of confinement ...
  • Plümper, Oliver; Botan, Alexandru; Los, Catharina; Liu, Yang; Malthe-Sørenssen, Anders; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    The transport of fluids through the Earth’s crust controls the redistribution of elements to form mineral and hydrocarbon deposits, the release and sequestration of greenhouse gases, and facilitates metamorphic reactions ...
  • Austrheim, Håkon Olaf; Dunkel, Kristina G; Plümper, Oliver; Ildefonse, Benoit; Liu, Yang; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Fractures and faults riddle the Earth’s crust on all scales, and the deformation associated with them is presumed to have had significant effects on its petrological and structural evolution. However, despite the abundance ...
  • Jamtveit, Bjørn; Moulas, Evangelos; Andersen, Torgeir Bjørge; Austrheim, Håkon Olaf; Corfu, Fernando; Petley-Ragan, Arianne Juliette; Schmalholz, Stefan Markus (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Studies of mineral equilibria in metamorphic rocks have given valuable insights into the tectonic processes operating at convergent plate margins during an orogeny. Geodynamic models simulating orogenesis and crustal ...
  • Hawkins, Christopher; Angheluta, Luiza; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    A supersaturated fluid flowing over a reactive, rough surface leads to complex precipitation patterns. We study the growth and interaction between discrete precipitates along a reactive wall in a nonlaminar channel flow. ...
  • 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 ...
  • Petley-Ragan, Arianne Juliette; Dunkel, Kristina G; Austrheim, Håkon Olaf; Ildefonse, Benoit; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Coseismic damage associated with earthquakes in the lower continental crust is accompanied by postseismic annealing and fluid‐mediated metamorphism that influence the physical and chemical development of the continental ...
  • Aupart, Claire Olga Maryse; Dunkel, Kristina G; Angheluta, Luiza; Austrheim, Håkon Olaf; Ildefonse, Beniot; Malthe-Sørenssen, Anders; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    The grain size distribution of deformed rocks may provide valuable information about their deformation history and the associated mechanisms. Here we present a unique set of olivine grain size distributions from ultramafic ...
  • Røyne, Anja; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
  • Torsvik, Trond Helge; Amundsen, Hans; Hartz, Ebbe Hvidegård; Corfu, Fernando; Kusznir, Nick; Gaina, Carmen; Dubrovin, Pavel; Steinberger, Bernard; Ashwal, Lewis D.; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2013)
    The Laccadive–Chagos Ridge and Southern Mascarene Plateau in the north-central and western Indian Ocean, respectively, are thought to be volcanic chains formed above the Réunion mantle plume1 over the past 65.5 million ...
  • Clerc, Adriane; Renard, Francois; Austrheim, Håkon Olaf; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)
    In the Bergen Arc, western Norway, rocks exhumed from the lower crust record earthquakes that formed during the Caledonian collision. These earthquakes occurred at about 30–50 km depth under granulite or amphibolite facies ...
  • Dunkel, Kristina G; Austrheim, Håkon Olaf; Ildefonse, Benoit; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    Our ability to decipher the mechanisms behind metamorphic transformation processes depends in a major way on the extent to which crystallographic and microstructural information is transferred from one stage to another. ...
