  4. 13. 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. 14. Metals released from mine waste deposits : Redistribution and fluxes through geological barriers

    Författare :Karsten Håkansson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The redistribution of metals from point sources (sulphidic mine waste) is presented in this thesis. The impact on surface water systems is determined from water quality and sediment data. It is generally found that lakes act as sinks for the metals, to a different extent for eachmetal. LÄS MER

  7. 15. Mobility of gold and other metals during alteration of the oceanic crust : Implications for the formation of VMS deposits

    Författare :Clifford G. C. Patten; Iain K. Pitcairn; Damon A. H. Teagle; Mark Hannington; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geology; geologi;

    Sammanfattning : Tremendous physical and chemical exchanges occur along oceanic ridges between the lithosphere, the hydrosphere and the biosphere. During these exchanges important mobilisation of metals by hydrothermal fluid circulation takes place within the oceanic crust. LÄS MER
