  1. 1. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Johanna Bergström; [2023-09-15]
    Nyckelord :Acid sulfate soil; AS soil; ERT measurements; resistivity; Baltic basin; Swedish west coast; acidification; Tapes transgression;

    Sammanfattning : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. LÄS MER

  3. 2. Geological 3D Modelling ofthe File Hajdar Quarry, Slite

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Friberg Nils; [2023]
    Nyckelord :3D-modelling; Cementa; limestone; resistivity; Gotland; 3D-modellering; Cementa; kalksten; resistivitet; Gotland;

    Sammanfattning : Located on the island of Gotland, Sweden, the File Hajdar limestone quarry is an important locality for domestic cement production. With depositional settings generally related to shallow sea carbonate ramps, the lithologies encountered on File Hajdar range from reef-associated limestone units to more basinal deposition of marls.

  4. 3. 3D modelling and resistivity measurements for hydrogeological assessments in the northern part of Vombsänkan

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Farid Khorshidian; [2023]
    Nyckelord :Conceptual 3D modelling; Resistivity; Hydrogeology; Blue Transition; Vombsänkan; Vombverket; Earth and Environmental Sciences;

    Sammanfattning : The geology of Vombsänkan is characterized by a complex sequence of Quaternary deposits overlying the Paleozoic sedimentary bedrock. The area is 759 km2 and has recorded several ice advances followed by glacial retreats and ice melting. LÄS MER

  5. 4. Petrophysical Properties of Rocks in Central Kiruna Mining District, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Simon Peter Dagbui; [2023]
    Nyckelord :Kiruna mining district; Common earth model; petrophysics; density; AMS; complex electrical resistivity; NRM; magnetization; IOA; Kirunavaara Mineralization;

    Sammanfattning : High economic and metallogenic significance of northern Norrbotten ore district in Sweden which hosts Kiruna mining district makes it a very important ore district in the world. Northern Norrbotten ore district contributes a combined 90 percent of iron production in Europe. LÄS MER

  7. 5. Processing of ERT data from Stabilised Columns

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Mårten Petersson; [2023]
    Nyckelord :inversion; ERT; quality control; jet grouting; aarhusinv; Technology and Engineering;

    Sammanfattning : Modern construction sites are associated with high demands on suitable soil conditions, resulting in geotechnical challenges that can be solved using soil stabilisation techniques. The reliability of these techniques is tested using different quality assurance methods. LÄS MER
