The GOM basin includes strata beneath the present-day Gulf of Mexico and extends onshore beneath the Gulf coastal plain of Mexico and the United States. Sediment is supplied primarily by fluvial systems draining the ancestral Mississippi River system and smaller river systems draining the Rocky, Ouachita, and Appalachian mountain ranges. Lesser amounts of carbonate sediments are produced locally by biochemical processes. Critical to the understanding of the GOM basin history and the associated [[petroleum system]]s of the northern Gulf of Mexico is the interaction of the Cretaceous-Holocene Mississippi drainage basin and thick salt deposited during the Jurassic.

It also shows the interpreted limits of thick Jurassic salt (>1.5 km). The geographic shifts of primary fluvial input have resulted in depocenters of different ages across the GOM Tertiary basin.
