  1. 16. 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. 17. Multielemental analysis of geological and biological samples using laser ablation ICP-SFMS

    Författare :Mikael D. Axelsson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

    Sammanfattning : The analytical performance of laser ablation (LA) for multielemental determination of geological and biological samples has been investigated. In the present study, LA has been used for sample introduction in inductively coupled plasma sector field mass spectrometry (ICP-SFMS). LÄS MER

  4. 18. 3D Geophysical and Geological Modeling in the Skellefte District: Implications for Targeting Ore Deposits

    Författare :Alireza Malehmir; Ari Tryggvason; Christopher Juhlin; Bernd Milkereit; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geophysics; Seismic reflection; Hardrock; VHMS deposits; Potential field; 3D geologic model; Skellefte District; Geofysik;

    Sammanfattning : With the advancements in acquisition and processing of seismic reflection data recorded over crystalline rocks, building three-dimensional geologic models becomes increasingly favorable. Because of little available petrophysical data, interpretations of seismic reflection data in hardrock terrains are often speculative. LÄS MER

  5. 19. On the applicability of geophysics for groundwater investigations in areas with lack of hydrogeological information. Examples from Mozambique

    Författare :Farisse Joao Chirindja; Teknisk geologi; []
    Nyckelord :Mozambique; Geophysics; Reference data; Hydrogeology; Groundwater;

    Sammanfattning : The work presented in this thesis has aimed to improve the knowledge about the groundwater occurrence in different geological conditions in Mozambique. The main focus in this study has been on the understanding of hydrogeological conditions in area with little background information by use of geophysical investigation. LÄS MER

  7. 20. Resistivity and Surface Wave Seismic Surveys in Geotechnical Site Investigations

    Författare :Roger Wisén; Teknisk geologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geografi; Hydrogeologi; teknisk geologi; Hydrogeology; geographical and geological engineering; resistivity method; surface wave seismic method; inverse modelling; site investigation; geophysics;

    Sammanfattning : The adaptation of geophysical methods for civil engineering purposes represents an important contribution to the development of geotechnical site investigation methodology. The term geotechnical site investigation here refers to all investigations performed prior to or during construction; i.e. LÄS MER
