==Summary of GOM fluvial history==
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 (Figure 4-4). Subsidence is related to basement cooling or differential response of basement types to loading (Figure 4-6). 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 section D.

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 section D.
