Structural styles in the deep-water Gulf of Mexico are largely a function of the distribution of salt, its interaction with sedimentary depo-centers, the specific Gulf of Mexico linked system involved, and position in that linked system. Nearly basin wide coverage of high quality 3D seismic data coupled with existing regional 2D data has allowed interpretation of sub-salt structural features and assembly into a broad regional framework. We identify and characterize the following provinces and subsalt structural elements. 1) A deep salt basin and frontal salt napppe; 2) Perdido fold belt and Alaminos Canyon gravity minima; 3) Eocene and Miocene regional welds; 4) an "egg crate?? province of isolated primary depo-centers separated by older salt and younger mini-basins; 5) an area of amalgamated salt and linked primary depo-centers; 6) Mississippi Canyon/Atwater, and Spirit fold belts; 7) Sigsbee salt lobe and allochthonous carapace basins; and 8) "ramps?? between weld and canopy levels.
