==Formation of the east breaks minibasin==

Each of these minibasins formed as sea level fell and the sediment supply system prograded to the shelf edge where it oversteepened and differentially loaded slope muds. Growth faults developed within this unstable sediment prism and displaced mobile salt to accommodate the downbuilding sediment.<ref name=ch04r117>Winker, C., D., Edwards, M., B., 1983, Unstable progradational clastic shelf margins: SEPM Special Publication 33, p. 139–157.</ref> This process continued until the salt was completely displaced and the downbuilding sediments welded with the sediments underlying the displaced salt.<ref name=ch04r110>West, D., B., 1989, Model for salt deformation on deep margin of central Gulf of Mexico basin: AAPG Bulletin, vol. 73, p. 1472–1482.</ref> Once the sediment-on-sediment welding occurred, the fault system either propagated downward or locked up, resulting in the basin filling to the equilibrium profile of the sea floor. The next cycle of minibasin downloading, growth fault development, and salt withdrawal stepped basin-ward to the next deformable site. That site could be either at the shelf/slope break or within an upper slope valley.
