dc.description.abstract The interpretation of 3D seismic data from Ship Shoal South Addition Blocks 349 -358 , Gulf of Mexico shows a complex interaction between salt , faults , and sedimentary strata . Reconstruction of the geometry of early Pliestocene (about 3 .65 Ma ) through recent salt and associated sediments reveals the evolution of a supralobal basin in the study area . The basin depocenter shifted from the northeastern part to the center of the study area through time . A small , bulb -shaped , salt -stock structure occurs in the northwest , and a salt sheet structure is present in the southeastern part of the study area . Those structures are part of a pennant -shaped structure bounded by counter regional faults trending northeastward . Salt movements created instability and triggered extensive faulting of the overlying strata . Three -dimensional reconstruction suggests that salt blocked the sediment during the early Pleistocene . The sediment was diverted around the salt high on both east and west sides of the salt body to the southwest and southeast . Stratigraphic interpretation of the interval between 1 .35 Ma and 1 .95 Ma led to the identification of a highstand systems tract (HST ) , a transgressive systems tract (TST ) , and two lowstand systems tracts (LST ) . The strata are developed normally in the depocenter area , whereas the strata at the basin margin were deformed by salt movement and faulting . Each systems tract is uniquely associated with a certain seismic facies . Three seismic facies were identified associated with LST , TST , and HST . Additionally , seismic sections reveal channel geometries in the LST . Seismic attribute analysis elucidates facies distribution in the systems tracts . Because of its ability to move , to divert sediment , to create instability , and to block sediment transport pathways , salt exercises the main control on the sedimentary processes in the study area . en_US
