  1. 1. A Geophysical Survey of Northern Utö

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Nicole Flanders; [2023]
    Keywords : ;

    Abstract : A geophysical investigation on the northern part of Utö was carried out between 2020 and 2021 to asses the extent of the iron ore (BIFs) and the iron bearing sulfides that have been surveyed and mined in the past. The survey using analog field equipment combined magnetometry, gravimetry, susceptibility, leveling, density, and thin-section microscopy. READ MORE

  4. 3. A comparison of 2D and 3D resistivity surveys for 3D inversion imaging

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Julia Cavell; [2022]
    Keywords : ;

    Abstract : Following study focuses on electrical resistivity surveying and how it can be used as an exploration method to increase knowledge of subsurface structures. Future scenarios with increasing population and rapid urbani-zation, put high demands on reliable infrastructure; safe foundations, un-derground structures, environmental safety and access to resources.

  5. 4. LÖDÖSEHUS: GEOPHYSICAL METHODS FOR DESCRIBING ARCHAEOLOGY AND NEAR-SURFACE GEOLOGY AT THE SITE OF A MEDIEVAL CASTLE IN LÖDÖSE, SW SWEDEN

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Fredrik Andersson; Tobias Möhl; [2021-09-21]
    Keywords : Near-surface geophysics; Ground-penetrating radar; Resistivity; Induced Polarization; Archaeology; Leached clay; Medieval castle; Lödösehus; Lödöse; Sweden;

    Abstract : Near-surface geophysics is a well established method for mapping the geological conditions in the subsurface. The use of geophysics is also a commonly used method in archaeological surveys, although traditionally not as much in Sweden. READ MORE

  6. 5. Feasibility of Enhanced Geothermal Systems in the Precambrian crystalline basement in SW Scania, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Hanna Kervall; [2021]
    Keywords : EGS; deep drilling; geothermal; petrology; petrophysical properties; Sveconorwegian; Earth and Environmental Sciences;

    Abstract : The ability to evaluate the geothermal potential at a depth of five to six kilometres in the crystalline bedrock is crucial for the EGS-technology to be utilized in the future. This work focuses primarily on presenting expected geological conditions at great depths in southwestern Scania. The study is based on information from E. READ MORE
