  1. 1. Plane wave electromagnetic measurements for imaging fracture zones

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Lena Persson; Uppsala universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Electromagnetic Measurements Fracture Zones; Geofysik; NATURAL SCIENCES Physics Other physics Geophysics; NATURVETENSKAP Fysik Övrig fysik Geofysik; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : Electromagnetic fields from distant radio transmitters interact with the resistivity structures in the earth. They can be regarded as plane-wave fields since their penetration depth is much smaller than their wavelength. LÄS MER

  2. 2. Seismics, 2D and 3D Inversion of Magnetotellurics Jigsaw pieces in understanding the Skellefte Ore District

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Sammanfattning : The Skellefte District (SD) is one of the richest metallogenic mining areas in Sweden. The main deposits consist of volcanic-hosted massive sulphides (VHMS) rich in zinc, copper, lead, gold and silver, that have been explored and mined for more than a century. LÄS MER

  3. 3. Characterization of the structure, stratigraphy and CO2 storage potential of the Swedish sector of the Baltic and Hanö Bay basins using seismic reflection methods

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Daniel Sopher; Uppsala universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; Baltic Basin; Hanö Bay Basin; OPAB dataset; Seismic reflection; CO2 storage capacity; Seismic interpretation; Seismic processing; Vectorising; Digitizing; Tornquist Zone; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : An extensive multi-channel seismic dataset acquired between 1970 and 1990 by Oljeprospektering AB (OPAB) has recently been made available by the Geological Survey of Sweden (SGU). This thesis summarizes four papers, which utilize this largely unpublished dataset to improve our understanding of the geology and CO2 storage capacity of the Baltic and Hanö Bay basins in southern Sweden.

  4. 4. Reflection seismic investigation in the Skellefte ore district A basis for 3D/4D geological modeling

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mahdieh Dehghannejad; Uppsala universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Skellefte district; reflection seismic; mineral exploration; 3D 4D modeling; mineralization; faults and shear zones; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : The Skellefte ore district in northern Sweden is a Palaeoproterozoic volcanic arc and one of the most important ones hosting volcanogenic massive sulfide (VMS) deposits, producing mainly base metals and orogenic gold deposits. Due to high metal prices and increased difficulties in finding shallow deposits, the exploration for and exploitation of mineral resources is quickly being moved to greater depths. LÄS MER
