Figure 4. The present-day structure of the basin is dominated by prominent north-south lineaments corresponding to the Alpha Fault and Davie Fracture Zone (DFZ), both dextral strike-slip fault complexes. The tectonic framework and bathymetry map show that the region between Alpha Fault and Davie Fracture Zone (DFZ), in Block 5, occurs in ultra-deepwater (1600-3000m) where the main leads and prospects have been mapped.
