AREA: Geociências
SUMMARY:

Salt tectonics concerned with the geometries and processes associated with the presence of significant salt thicknesses within stratigraphic sequence. Salt behaves like a viscous fluid over geological time scales and, therefore, it may flow due to lateral differences in thickness and density of the supra-salt layers. This influences the structural evolution of sedimentary basins, and related structures are remarkably important for the exploration of mineral resources, oil and gas, as well as for energy storage such as gas in salt caverns (e.g. hydrogen and compressed air), CO₂ storage, and geothermal energy. Therefore, understanding the processes involved in salt tectonics has important scientific, economic, and social implications. In this regard, recent advances in analog modeling have been contributing to the hydrocarbon exploration and production industry associated with salt tectonics as one of the most powerful and visual tools for understanding 3D and 4D structural evolution of sedimentary basins. Knowledge of the model setup and combined with serial sections allows for the identification and understanding of structural processes within basins as well as providing possible geometries of poorly imaged structural geometries in seismic data. This thesis investigates the impacts of lateral and vertical salt flow on the supra-salt tectono-stratigraphic architecture developed in the realm of extensional basins as well as the origin and evolution of salt structures and supra-salt deformation in response to base-salt relief during gravity gliding in Atlantic-type salt basins formed in passive margin settings. To achieve this, the thesis uses a wealth of analog models in different settings of passive margins and continental rifts. This detailed and incremental approach allows for greater confidence in interpreting complex salt-related geometries and kinematics, improving their understanding. Although we do not address our models to specific salt basins, the structural processes and salt-related geometries modeled are also comparable and relevant to many other salt-bearing rifted margins (e.g., Gulf of Mexico, West Africa, East Brazil).
