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. Influence of Foundation Modelling on the Seismic Response of a Concrete Dam

   University essay from KTH/Betongbyggnad

   Author : Stella Harrison; Siri Nöjd; [2021]
   Keywords : concrete dam; earthquake; finite element analysis; free-field forces; mass foundation; betong dam; jordbävning; finita element analys; free-field forces; inkluderad bergsmassa;

   Abstract : It is of great importance to ensure the structural safety of dams during earthquakes since a failure may cause catastrophic consequences. Conventional computation of the structural response of dams is based on a simplified approach where the foundation is considered as massless. READ MORE

4. 3. 2D Reflection Seismic Imaging of Sparse 3D Data in the Zinkgruvan Mine, Central Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Maryam Abbasian; [2021]
   Keywords : 2D crooked-line; reflection seismic; sparse 3D; mineralization; Zinkgruvan; 2D modellering; reflektionsseismik; mineralisering; Zinkgruvan;

   Abstract : Zinkgruvan mining area in the southern Bergslagen mineral district of central Sweden holds over 30 million tons of massive sulphide mineralization. The ever-increasing global demand for mineral/metal resources, together with metal consumption growth especially for high-tech purposes has made the exploration of these resources of particular importance.

5. 4. 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

6. 5. Analysis of Seismic Data Acquired in the Hverahlíð Geothermal Area

   University essay from Uppsala universitet/Geofysik

   Author : Agnieszka Stoch; [2020]
   Keywords : Hverahlíð geothermal area; reflection seismic; virtual reflection seismic profiling; virtual shot gather; cross-correlation; autocorrelation;

   Abstract : Volcanic rifting environments, such as in Iceland, are challenging for conventional seismic reflection methods using active surface seismic sources. This study demonstrates the potential of a novel technique, called Virtual Reflection Seismic Profiling (VRSP) for imaging reflections in geothermal regions, like Hverahlíð, where a dense seismic array recorded a number of local microearthquakes for cross-correlation.
