  1. 1. A geophysical study of a drumlin in the Åsnen area, Småland, south Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Besnik Asani; [2015]
    Keywords : Geophysics; drumlin; resistivity; induced-Polarization; electromagnetic slingram; Earth and Environmental Sciences;

    Abstract : The sediment composition of drumlins in the Åsnen area in Småland, south Sweden is poorly studied. Excavations are being planned with intention to study the internal architecture and composition of these drumlins. READ MORE

  2. 2. Mapping leachates and subsurface structures using different geophysical methods.

    University essay from KTH/Mark- och vattenteknik (flyttat 20130630); KTH/Mark- och vattenteknik (flyttat 20130630)

    Author : David Barkels; Johan Åberg; [2012]
    Keywords : geophysics; tailings; acid mine leachate; pollution mapping; CVES; GPR; slingram;

    Abstract : The enrichment of ore produces large amounts of sulfur and metal-rich residual waste called tailings, which need to be deposited and stored for a long time. When the tailing is oxidized, large amounts of protons and metals are dissolved and diffuse to the groundwater. READ MORE

  3. 3. Resistivity and IP measurements at the Bolmen Tunnel and Ådalsbanan, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Miriam Cegrell; Jimmy Mårtensson; [2008]
    Keywords : resistivity; induced polarisation IP ; geophysics; geology; Bolmen; Ådalsbanan; resistivitet; inducerad polarisation IP ; geofysik; geologi; Earth and Environmental Sciences;

    Abstract : In all tunnel construction projects geophysical methods are important as a foundation for engineering geological conceptual models. Detailed information about the condition and the physical properties of rocks at depth is desirable, and geophysical methods have the potential to exploit these properties. READ MORE

  4. 4. Measuring techniques of Induced Polarization regarding data quality with an application on a test-site in Aarhus, Denmark and the tunnel construction at the Hallandsås Horst, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Carl-Henrik Månsson; Jonas Siikanen; [2007]
    Keywords : Induced Polarization; capacitive coupling; separated cables; chargeability; CVES; the Hallandsås Horst; inducerad polarisation; kapacitiv koppling; separerade kablar; Hallandsås; Earth and Environmental Sciences;

    Abstract : It has been shown that surveys of Induced polarization (IP) often contain data of low quality, because it is highly sensitive against different noise sources. When measuring induced polarization, where the method uses multicore cables and continuous electrode sounding (CVES, Continuous Vertical Electrical Sounding), noise phenomena such as capacitive coupling effects have to be considered.
