    • Crystal rotations and alignment in spatially varying magma flows: 2-D examples of common subvolcanic flow geometries 

      Vachon, Remi Elie Celestin; Bazargan, Mohsen; Hieronymus, Christoph F.; Ronchin, Erika; Almqvist, Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-31)
      Elongate inclusions immersed in a viscous fluid generally rotate at a rate that is different from the local angular velocity of the flow. Often, a net alignment of the inclusions develops, and the resulting shape preferred orientation of the particle ensemble can then be used as a strain marker that allows reconstruction of the fluid’s velocity field. Much of the previous work on the dynamics of ...

    • Glacially Induced Stress Across the Arctic From the Eemian Interglacial to the Present—Implications for Faulting and Methane Seepage 

      Vachon, Remi Elie Celestin; Schmidt, P.; Lund, Bjorn; Plaza-Faverola, Andreia; Patton, Henry; Hubbard, Alun Lloyd (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-28)
      Strong compressive and shear stresses generated by glacial loading and unloading have a direct impact on near-surface geological processes. Glacial stresses are constantly evolving, creating stress perturbations in the lithosphere that extend significant distances away from the ice. In the Arctic, periodic methane seepage and faulting have been recurrently associated with glacial cycles. However, ...
