1. New Techniques for Estimation of Source Parameters : Applications to Airborne Gravity and Pseudo-Gravity Gradient Tensors
Sammanfattning : Gravity gradient tensor (GGT) data contains the second derivatives of the Earth’s gravitational potential in three orthogonal directions. GGT data can be measured either using land, airborne, marine or space platforms. LÄS MER
2. Seismotectonics and lithospheric structure of Costa Rica
Sammanfattning : The interaction of different tectonic features on a short-distance scale of 100's of km produces the complexity of the Costa Rica region. The intraplate Caribbean earthquake activity of shallow-depth nature is mainly concentrated along an E-W axis in the central part of the country. LÄS MER
3. Crustal stress studies using microearthquakes and boreholes
Sammanfattning : The state of stress in the crust is essential for the understanding of geodynamic processes such as the transmission of plate driving forces through the lithosphere and the triggering of earthquakes. This thesis describes the development and application of new methods for the estimation of crustal stresses. LÄS MER
4. Geophysical and petrophysical characterisation of the Tjårrojåkka IOCG mineralisation, Sweden
Sammanfattning : A geophysical-petrophysical study has been performed in an area WSW of the city of Kiruna, northern Sweden. Particular attention has been dedicated to the Tjårrojåkka iron oxide copper gold (IOCG) mineralisations. LÄS MER
5. Superimposition of Contractional Structures in Models and Nature
Sammanfattning : Superimposition of contractional structures is widely observed in different scales in the world. Superimposed structures form due to different processes: change in strain accommodation from one type of structure to another during a single progressive shortening; successive coaxial shortening phases separated by an unconformity; superimposition of different non-coaxial shortening phases.
