==Discussion of GOM basin==

Much of the petroleum discovered within the northern GOM basin is in Neogene anticlinal and [[stratigraphic trap]]s developed as a consequence of interaction between Jurassic salt and Cenozoic siliciclastic progradation. The basic model consists of sediment prograding into the basin and differentially loading the plastic salt, causing diapirs and growth faults to develop.<ref name=ch04r98>Trippet, A., R., 1981, Characteristics of diapirs on the outer continental shelf–upper continental slope boundary, northwest Gulf of Mexico: Gulf Coast Assoc. of Geological Societies Transactions, vol. 31, p. 391–397.</ref><ref name=ch04r46>Ingram, R., J., 1991, Salt tectonics, in Goldthwaite, D., ed., An Introduction to Central Gulf Coast Geology: New Orleans Geological Society, p. 31–60.</ref> Two different interpretations of the present-day geology are presented below in two different structural cross sections. [[Migration]] of hydrocarbons from Mesozoic and early Tertiary organic-rich rocks are significantly affected by the selection of either of these two interpretations of salt deformation.
