Mesozoic and Cenozoic fluvial systems have filled in the northern margins of the GOM rift basin, prograding the continental margin of one area until sediment input shifts to another area ([[:file:sedimentary-basin-analysis_fig4-4.png|Figure 1]]). Subsidence is related to basement cooling or differential response of basement types to loading ([[:file:sedimentary-basin-analysis_fig4-6.png|Figure 2]]). Formation of diapirs and tectonic movement of growth fault systems has already being discussed as it relates to sediment loading. Fluctuation in sea level is discussed in [[Sea level cycle phase]].
