Salt‐Detached Strike‐Slip Faulting, Outer Kwanza Basin, Offshore Angola

We here use a 3D seismic reflection dataset from the Outer Kwanza Basin, offshore Angola to examine structure and growth of salt-detached strike-slip faults. The faults occur in four, up 13.8 km-long, NE-trending arrays that are physically linked by restraining bends releasing stepovers, which presently overlie Aptian salt base-salt relief related pre-salt faulting. suggest these formed accommodate along-margin variations rate magnitude differential seaward translation diapirism, commenced Early Cretaceous. illustrate grew tip propagation isolated fault segments, some during Albian-Cenomanian (i.e., 113–100.5 Ma, or initial 11%–13% their deformation history). Some then reached near-final length within subsequent ca. 77 Ma (or next 69%–81% history), while others attained this later, 18 after 95% During time, segments breached with as whole growing alternating periods lengthening throw accumulation, punctuated phases inactivity. Our results also show scatter D-L scaling reflects propagation, interaction, linkage individual segments.
