1. A Structural Analysis of the Fracture Sets in Gothenburg, Sweden: A Remote Sensing and Manual Lineament Approach
University essay from Göteborgs universitet/Institutionen för geovetenskaperAbstract : The fracture-valley landscape within the Gothenburg region was analysed based on LiDAR-derived hillshade images as well as several sources of orthomosaics. Using a manual lineament interpretation approach and complimented with an objective fractal analysis software (FROST), the objective of the study was to characterise the regional fracture sets as well as attempt to link the sets to the complex regional geological history.

2. Microstructural evolution of ice under simple shear deformation
University essay from Göteborgs universitet/Institutionen för geovetenskaperAbstract : To investigate microstructure in ice deformed under simple shear conditions experiments were performed with artificial polycrystalline ice and natural ice samples form Vatnajökull glacier in Iceland. A new deformation apparatus was tested and results from deformation were compared to literature to validate the method. READ MORE

3. Kinetic interpretation of microstructures in the Gällivare area; implications for deformation phases and related metamorphic events.
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : The goal of this study was to identify and describe different microstructures observed in samples from two major shear zones in the Gällivare area, namely the Nautanen Deformation Zone (NDZ), and the Fjällåsen deformation zone (FDZ). Thirteen samples were examined during this study. READ MORE

4. Seismic tomography as an instrument for structural evaluation in the Printzsköld and Alliansen ore bodies, Malmberget
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : The Malmberget deposit is one of the major apatite iron ores in Europe, located in northern Norrbotten. As the mining in Malmberget proceeds deeper more challenges with the stability have been faced. When the stress distribution of a rock mass exceeds the rock strength energy in form of seismic waves is released. READ MORE

5. A 4D Analysis of a Minor Graben Structure at Ekolsund, South Central Sweden
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The objective of this project is about a kinematic analysis of a shear zone, specifically a graben structure. The surface of the study area has also been investigated, this is to understand if a faulting reactivation has occurred due to glacial impact. READ MORE
