21. Inversion and Joint Inversion of Electromagnetic and Potential Field Data
Sammanfattning : In this thesis, four inversion problems of different scale and difficulty are solved. Two of them are electromagnetic inverse problems. Two more are joint inversion problems of potential field data and other types of data. LÄS MER
22. Joint inversion and integration of multiple geophysical data for improved models of near-surface structures
Sammanfattning : Geophysical methods are non-invasive and allow an effective way of understanding subsurface structures and their physical properties. One of the main challenges is the often non-uniqueness of the geophysical models and that several different models can explain a dataset to an agreeable fit. LÄS MER
23. Seismic imaging of volcanogenic massive sulphide deposits : From legacy to innovative surveys
Sammanfattning : The volcanogenic massive sulphide deposits at the Neves-Corvo mine area, part of the Iberian Pyrite Belt in southern Portugal, were studied using seismic methods. Three distinct reflection seismic datasets were used in this study: a 2D legacy data from 1996, an innovative 2019 surface and in-mine acquisition, and a 2011 3D seismic survey. LÄS MER
24. Altiplanic aquifer exploration by multidisciplinary methods : Addressing the basis of sustainable use of groundwater
Sammanfattning : The sustainable use of groundwater relies on building up three stages: exploration, development and management. The exploration is crucial to understand the capabilities and limitations of aquifer units; e.g. LÄS MER
25. Crustal architecture of the Kiruna mining district : Structural framework, geological modeling, and physical rock property distribution
Sammanfattning : Rapid technological advancements and growing environmental consciousness created a shifting dynamic of metal demand within the context of contemporary global challenges. The metals play a pivotal role in this transformation and remarkable surge in demand is expected. LÄS MER
