Description:
Based on available nonexclusive seismic data, a preliminary model has been developed for salt deformation on the deep margin of the central Gulf of Mexico basin. In this model, the Tertiary clastic wedge prograded to the basinward limit of original Jurassic salt by the middle Miocene. As the salt and overburden thinned basinward, lateral flow, combined with a strong component of downward force exerted by subsiding voluminous middle Miocene loading, caused the basinward limit of the Louann Salt to effectively shear off. Deposition of the upper Miocene and Pliocene sediments was confined primarily shoreward of an incipient salt swell, but Pleistocene sediments were eventually able to breach the barrier.
