Description
Summary:Normal faults play a crucial role in understanding the dynamic processes of the Earth, shaping landscapes, influencing sedimentary basins’ distribution, energy resources, and impacting seismic activities. However, much remains to be unravelled, such as the variation of slip rates over time and changes in a fault’s sealing potential throughout its lifespan. In this thesis, I investigate the geometric and kinematic variability of normal faults over time and their implications for fluid flow using age-constrained 3D seismic reflection and wellbore data from the SW Barents Sea. First, I constrain the four-dimensional evolution of extensional growth folds using the stratigraphic record. This reveals that fault-propagation folding can occur in multiple phases, as a protracted process. Next, I focus on the understudied early stage of normal fault growth, providing critical observational datasets that contribute to fault growth models. The results show that there is no universal law that explains normal fault ...
