Sediment supply from the North American continents has filled nearly one half of the basin since its inception, primarily by offlap of the northern and northwestern margins.

Like other oceanic basins, total subsidence of the Gulf basin is the sum of crustal stretching, cooling, and loading subsidence. Combined stretching and subsequent cooling during and after late Jurassic spreading caused a total tectonic subsidence...
