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]]. | 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.
