==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 fault]]s 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.
