6. Geophysical investigation for 3D geological modelling and ore exploration in the Skellefte mining district
Sammanfattning : The Skellefte mining district, northern Sweden, is regarded as one of the country’s richest mineral districts. Most of the outcropping deposits in this district or those deposits which are located at shallow depths (≤ 300 m) are likely to have already been discovered, which motivated the Swedish mining companies to expand their explorations at greater depths (e.

7. A geophysical investigation of carbonate build-ups in the Baltic Basin using reflection seismic and well data
Sammanfattning : During the Late Ordovician, the region around Gotland was part of a shallow epicratonic basin in the southern subtropics. Low latitudes, relatively warm sea temperatures and the presence of a shallow marine environment promoted algae to flourish and diverse carbonate build-ups such as carbonate mounds and reefs developed on the southern margin of Baltica.

8. Resistivity and Surface Wave Seismic Surveys in Geotechnical Site Investigations
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
9. Multidisciplinary Near-Surface Investigation of a Quick-Clay Landslide Prone Area in Southwest Sweden
Sammanfattning : Quick-clay landslides are considered one of the most important geohazards in Sweden, Norway, and Canada. The deposits involved are glacial and postglacial clays and silty clays, which are very sensitive to increased stress that may collapse their structure and cause liquefaction. LÄS MER
10. On the applicability of geophysics for groundwater investigations in areas with lack of hydrogeological information. Examples from Mozambique
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
