By restoring six stratigraphic markers in map view, we have studied the kinematics of a growth fault system (involving a major fault, its antithetic and a faulted roll-over) located within the Niger Delta (offshore Nigeria). Restoration yields, for each marker, the horizontal displacements due to normal faulting and the associated fields of block rotation about vertical axes. As expected for a continuous history of growth faulting, the amount of extension computed for each stratigraphic marker increases with depth. From the fields of finite displacement and block rotation, we find that horizontal extension perpendicular to fault traces is associated with a minor amount of bulk left-lateral wrenching, accommodated by counterclockwise rotation of blocks. Because the overall deformation differs from a plane strain, balancing of cross-sections alone would lead to some errors. We also computed incremental displacement fields for time intervals between successive stratigraphic markers. According to our results, during the first stages of growth faulting, displacement occurred only on the major faults; whereas, during later stages, larger horizontal displacements were accommodated by numerous small faults, probably responsible for the collapse of the roll-over.
