  1. 1. Paleomagnetic and Thermomagnetic Studies on Rock Samples from COSC - 1 Drilling Project

    University essay from Uppsala universitet/Geofysik

    Author : Wanyi Li; [2022]
    Keywords : Scandinavian Caledonides; remanent magnetization; AF demagnetization; temperature dependent magnetic susceptibility; Skandinaviska Kaledoniderna; remanent magnetism; växelfältsavmagnetisering; temperaturberoende av magnetisk susceptibilitet;

    Abstract : The COSC-1 borehole located in the Lower Seve nappe of the Central Scandinavian Caledonides is intended to study the tectonic evolution of the Paleozoic orogen. The drilling project reached a depth of 2495.8m and obtained samples from different lithologal units of mica schist, amphibolite, gneiss, and mylonitic gneisses. READ MORE

  2. 2. Reprocessing of Marine Reflection Seismic Data from Skåne, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Charlotta Carlsson; [2022]
    Keywords : Reflection seismics; marine geophysics; Claritas; Claritas; reflektionsseismik; geofysik;

    Abstract : During 1979, an oil prospecting project was initiated in the south of Sweden, outside the coast of the municipality of Skåne. No drilling program was initiated, and the project was put on ice. However, with the oil prices of today and the interest in carbon dioxide storage, the area could once again be interesting.

  3. 3. Developing data processing program for a new radio magnetotelluric (RMT) instrument

    University essay from Uppsala universitet/Geofysik

    Author : Elis Uebel; [2022]
    Keywords : RMT radio magnetotellurics matlab GUI;

    Abstract : The radio magnetotellucic (RMT) method originates from (Tikhonov, 1950) and (Cagniard,1953) who discovered the possibility to estimate resistivity in the Earth’s subsurface using naturally occurring telluric currents. This through measuring the surface impedance of electromagnetic waves. READ MORE

  4. 4. Rock Magnetic Studies of Magnetite and Quartzite: Results at Ambient Conditions and From Diamond Anvil Pressure Experiments (~2 GPa)

    University essay from Uppsala universitet/Geofysik

    Author : Dimitra Daniil; [2021]
    Keywords : magnetic susceptibility; remanent magnetization; mDAC; AF demagnetization; NRM; IRM; ARM; magnetisk susceptibilitet; magnetisk remanens; mDAC; AF demagnetisering; NRM; IRM; ARM;

    Abstract : Numerous techniques are used to study the magnetic history and properties of rocks, which provides important data on the Earth’s interior. In this study we conducted a series of experiments on two different sample sets, comprising pure magnetite (Set1) and a mixture of magnetite-hemoilmenite-bearing quartzite (Set2), in order to gather information about their magnetic susceptibility and remanent magnetization.

  5. 5. Integration of Borehole, Ground, and Airborne Data to Improve Identification of Areas With Quick Clays in Sweden

    University essay from Uppsala universitet/Geofysik

    Author : Oskar Rydman; [2021]
    Keywords : TEM; tTEM; Quick clay; SkyTEM; ATEM; CPTR; CPTU-R; Landslides; Frastad; TEM; tTEM; Quick clay; SkyTEM; ATEM; CPTR; CPTU-R; Jordskred; Fråstad;

    Abstract : The main focus of the project was the comparison of results from a new towed transientelectromagnetic (tTEM) data set with existing data including airborne transient EM(ATEM), radio magnetotellurics (RMT), cone penetration test with resistivity (CPT-R),geotechnical interpretations and geological observations in a quick clay landslide site atFråstad close to Lilla Edet in south-west Sweden. The tTEM data set was processedand inverted twice in the software Aarhus workbench using different inversion constraintsand settings. READ MORE
