The thesis is an example of an integrated (both geological and geophysical) analysis of seismic data, focused on structural and tectonic aspects. The analysis was made based on the detailed study of 3D seismic data (ZOCA-2 survey) form the Bonaparte Basin (NW Shelf of Australia) and interpretation of logs from Thorton-1 well. The literature review encompasses a broad spectrum of different problems like the regional geology of the NW Shelf of Australia, evolution and petroleum potential of individual basins and sub-basins forming northern Australian margin (chapter 2), some structural and tectonic problems (chapters 3 and 5) as well as stricte geophysical aspects like complex trace and seismic attributes analysis (chapter 4). Seismic data analysis was not only concentrated on structural and tectonic aspects, but also took into account preliminary structural traps integrity assessment (leaking due to fault reactivation). To support structural interpretation of conventional amplitude seismic data, seismic attribute analysis (especially helpful in Identification of polygonal faulting (chapter 4)) as well as synthetic seismic modelling (useful in the determination of type of linkage between faults forming a conjugate fault system recognized on seismic sections) were used. The final result of the integrated seismic interpretation is an tectonic evolutionary model of N part of the Bonaparte Basin (chapter 6), showing geometrical relationships between different fault systems as well as the approximate timing of deformation in relation to the stress field existed in a given time.
