  1. 1. Re-processing Reflection Seismic Data at a Quick-clay Landslide Site in Southwest Sweden

    University essay from Uppsala universitet/Geofysik

    Author : Zhaochen Mu; [2022]
    Keywords : reprocess; reflection seismic; tomography; quick-clay; landslide;

    Abstract : This MSc thesis reprocessed seismic data collected at a site near the Gota River in 2011, focusing on two lines. The two seismic lines ran through a landslide scar zone for a total length of 1 km, both of which used dynamite as the seismic source. READ MORE

  3. 2. Reflection Seismic Survey for Characterising Historical Tailings and Deep Targeting at the Blötberget Mine, Central Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : EMMANUEL ALOFE; [2021]
    Keywords : reflection seismic; exploration; tailings; sustainability; circularity; tomography; reflektion seismisk; prospektering; gruvavfall; hållbarhet; cirkularitet; tomografi;

    Abstract : Iron has been an essential element to human development and iron-oxide deposits are known to host minerals that are labelled as critical raw materials (CRMs), especially in the EU. Therefore, ensuring a sustainable supply of CRMs require access to both primary and secondary sources of their host deposits such as iron oxides. READ MORE

  4. 3. 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).

  5. 4. Determining shallow P-wave velocity and its engineering implication in Adama City, Ethiopia

    University essay from Uppsala universitet/Geofysik; Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Tasnim Laskar; [2019]
    Keywords : Ethiopia; seismic refraction; earthquake;

    Abstract : A great number of the urban areas in Ethiopia are situated within the Great Rift Valley of Ethiopia, a system consisting of depressions and large faults. As a region with significant seismic activities, it is vital that careful planning is implemented to avoid constructing buildings on flat surfaces as they can amplify ground motion in the case of an earthquake.

  6. 5. Deriving Geothermal Reservoir Properties from Tomographic Models

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Samantha Kim; [2019]
    Keywords : Geothermal reservoir; super-critical fluids; optimization; seismic tomography; effective medium model; Iceland; Geotermisk energi; seismisk; mediummodel; reservoir; spricktäthet; superkritisk vätska optimisering;

    Abstract : The effectiveness of the heat transfer in a geothermal reservoir strongly depends on its temperature, pressure and rock type. A porous and fractured rock is essential to provide a hot fluid circulation to a geothermal power plant. READ MORE
