  1. 1. Reprocessing of Marine Reflection Seismic Data from Skåne, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Charlotta Carlsson; [2022]
    Keywords : Reflection seismics; marine geophysics; Claritas; Claritas; reflektionsseismik; geofysik;

    Abstract : During 1979, an oil prospecting project was initiated in the south of Sweden, outside the coast of the municipality of Skåne. No drilling program was initiated, and the project was put on ice. However, with the oil prices of today and the interest in carbon dioxide storage, the area could once again be interesting.

  3. 2. First-arrival traveltime tomography of active-source data in the Kansanshi copper mine, northern Zambia

    University essay from Uppsala universitet/Geofysik

    Author : Vessela Hobson; [2019]
    Keywords : refraction seismics; tomographic inversion; Zambian Copperbelt; copper;

    Abstract : Sedimentary rock-hosted deposits are a major source of copper and cobalt, with the Neoproterozoic central African Copperbelt being among the largest Cu-Co provinces in the world, accounting for around 15% of its copper resource. The deposits occur primarily in the carbonates and siliciclastic sediments overlying the basement, and formed during early diagenesis (around 820 Ma) and late diagenesis/metamorphism during the Pan-African Orogeny (580-520 Ma).

  4. 3. Semi-Analytical Finite Element method for guided waves in civil engineering plate-like structures

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Christian Nielsen; [2015]
    Keywords : seismics; structural health monitoring; lamb waves; SAFE; semi analytical finite element; wave guide finite element; non destructive testing; civil engineering; ultrasound; ultrasonography; comsol; wave guide; plate; Technology and Engineering;

    Abstract : Guided waves have a signicant potential for Structural Health Monitoring (SHM) and Non-Destructive Testing (NDT) due to their relatively long distance of propagation and sensitivity to discontinuities along the propagation path, anywhere through the material thickness. The inability to model wave guides of arbitrary cross-section using current matrix methods, has led to the development of a technique called Semi-Analytical Finite Element (SAFE). READ MORE

  5. 4. Structural model of the Lambarfjärden area from surface and subsurface data in connection with the E4 Stockholm bypass

    University essay from Berggrundsgeologi

    Author : Anna Vass; [2012]
    Keywords : Lambarfjärden; sturctural model; fracture; E4 Stockholm Bypass;

    Abstract : The present Master thesis is written in connection with the E4 Stockholm bypass, which is a future motorway linking northern and southern Stockholm, and will mostly run through tunnels. The bypass will cross the Lake Mälaren in the Lambarfjärden area, where a fault is indicated on the geological maps, which would create risks for tunneling. READ MORE
