  1. 1. Extracting 3D Information from 2D Crooked Line Seismic Data on Hardrock Environments

    Författare :Johiris Isabel Rodriguez Tablante; Christopher Juhlin; Pekka Heikkinen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Hardrock Environment; Crooked line; Reflection Seismics; signal-to-noise; cross-dip; cross-profile; Geovetenskap; Earth sciences; Geovetenskap;

    Sammanfattning : Seismic methods have been used in sedimentary environment for almost 80 years. During that time, exploration geophysicists have developed a number of techniques to handle specific aspects of working in sedimentary areas. LÄS MER

  3. 2. 2D and 3D Reflection Seismic Studies over Scandinavian Deformation Zones

    Författare :Emil Lundberg; Christopher Juhlin; Alireza Malehmir; Lars Nielsen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Azimuthal binning; Crooked-line geometry; Cross-dip; Fault zone; Hard rock seismics; MTFC; Quick clay; Shear zone; UDZ; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : The study of deformation zones is of great geological interest since these zones can separate rocks with different characteristics. The geometry of these structures with depth is important for interpreting the geological history of an area. LÄS MER

  4. 3. Active and passive seismic methods for investigating the glacially-triggered Burträsk fault

    Författare :Ruth A. Beckel; Christopher Juhlin; Alireza Malehmir; Lars Nielsen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Burträsk fault; Glacially-triggered faulting; Crooked-line reflection seismics; Cross-dip correction; Stacking-based location; Microearthquake source observations; Passive seismic imaging; Seismic interferometry; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : Glacially-triggered faults are of high scientific interest since their formation was likely accompanied by major earthquakes and they are still a centre of seismicity in northern Fennoscandia, today. Imaging their deeper structure mainly relies on reflection seismics since the method generally has the best resolving power at depth of all geophysical methods. LÄS MER
