The [[Gulf of Mexico (GOM]] basin includes strata beneath the present-day Gulf of Mexico and extends onshore beneath the  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 Mountains|Rocky]], [[Ouachita Mountains|Ouachita]], and [[Appalachian Mountains|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]].

[[:file:sedimentary-basin-analysis_fig4-2.png|Figure 1]] shows the geographic distribution of the [[Neogene]] Mississippi River drainage basin and distribution of the primary fluvial input systems (arrows). It also shows the interpreted limits of thick Jurassic salt (>1.5 km). The geographic shifts of primary fluvial input have resulted in [[depocenter]]s of different ages across the GOM Paleogene basin.
