11. Särpräglat : Vikingatida och tidigmedeltida myntfynd från Danmark, Skåne, Blekinge och Halland (ca 800-1130)
Sammanfattning : This thesis takes as its subject the Viking-Age and early medieval coin finds from South Scandinavia (i.e. Denmark and the provinces Scania, Blekinge and Halland in southern Sweden). The study consists of two parts. LÄS MER

13. 3D Geophysical and Geological Modeling in the Skellefte District: Implications for Targeting Ore Deposits
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
14. Metals released from mine waste deposits : Redistribution and fluxes through geological barriers
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
15. Mobility of gold and other metals during alteration of the oceanic crust : Implications for the formation of VMS deposits
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
