The deep water thrust belt, Orange Basin. Scene

VSA Author: Rob Butler
Interpretations: 1
Date Created: 2008-02-14

The frontal part of the DW thrust belt, offshore Namibia (Orange Basin). Note that - to a large part, reflector amplitude is retained close to the thrusts, indicating that deformation associated with these structures is strongly localised. Indeed there is little/no sesimic evidence for distributed strains in the section - either recorded by velocity pull up or amplitude loss.

Interpretation of the frontal part of the thrust belt, deep-water Namibia. Note the virtual absence of growth strata. The system is overlain by onlapping post-tectonic slope sediments.
