  • Extensional inheritance and surface processes as controlling factors of mountain belt structure 

    Erdős, Zoltán; Huismans, Ritske S.; van der Beek, Peter; Thieulot, Cedric (WileyAmerican Geophysical Union, 2014-12)

  • Seismiske bølger i havis 

    Bakke, Svein-Harald (The University of Bergen, 2015-03-23)
    Seismiske innsamlinger på havis gir under gitte forhold opphav til kildeinduserte fleksurbølger, og dette problemet oppstår når seismisk energi blir fanget mellom grenseflatene is-luft og is-vann. Fleksurbølgen kan ...

  • Contractional deformation of porous sandstones. Laramide and Sevier deformation of the Navajo and Aztec sandstones in western USA 

    Zuluaga, Luisa F. (The University of Bergen, 2015-02-16)
    In response to stress, high porosity sandstones tend to deform and localize strain in the form of deformation bands, which form by rotation, sliding and potentially crushing of grains. Contrary to slip surfaces and fractures, ...
