  2. 1. Modeling internal deformation of salt structures targeted for radioactive waste disposal

    Author : Zurab Chemia; Hemin Koyi; Harro Schmeling; Ian Alsop; Uppsala universitet; []
    Keywords : salt; diapir; anhydrite; deformation; entrainment; numerical modeling; rheology; sinking; Gorleben;

    Abstract : This thesis uses results of systematic numerical models to argue that externally inactive salt structures, which are potential targets for radioactive waste disposal, might be internally active due to the presence of dense layers or blocks within a salt layer.The three papers that support this thesis use the Gorleben salt diapir (NW Germany), which was targeted as a future final repository for high-grade radioactive waste, as a general guideline.

  4. 2. Strain quantifications in different tectonic scales using numerical modelling

    Author : Lukas Fuchs; Hemin Koyi; Susanne Buiter; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Deformation modelling; progressive and finite deformation; salt tectonics; down-built diapir; upper mantle; lithosphere-asthenosphere boundary; seismic anisotropy; plate-mantle de coupling; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

    Abstract : This thesis focuses on calculation of finite and progressive deformation in different tectonic scales using 2D numerical models with application to natural cases. Essentially, two major tectonic areas have been covered: a) salt tectonics and b) upper mantle deformation due to interaction between the lithosphere and asthenosphere. READ MORE
