Abstract
Salt deformation in offshore
southern Gabon is represented by mobilization of an Aptian salt layer in
reaction to Tertiary clastic progradation. Seismic mapping of salt bodies
and associated faulting has resulted in increased understanding of the
types and distribution of these salt bodies, their associated faulting
patterns, and some aspects of their origin.
Away from the Tertiary depocenter,
the growth history of salt swells or pillows can be determined by examining
onlapping and draping seismic reflectors. Significant Tertiary clastic
progradation into the area mobilized the salt and resulted in a series
of linear, deep salt walls and asymmetric, basinward-dipping salt rollers,
commonly associated with significant up-to-basin listric faulting. The
up-to-basin faulting dominates the southern Gabon subbasin. The expansion
history of associated sediments suggests that these faults expanded episodically
throughout the Tertiary, continuing to present-day bathymetric fault scarps.
The bias toward up-to-basin faults, to the apparent exclusion of down-to-basin
expansion faults, remains enigmatic. |
