Tectonic evolution of the [[basin::Gulf of Mexico basin]] has resulted in five primary tectonostratigraphic phases (A–E), each with a different sediment accumulation and deformation history. [[:file:sedimentary-basin-analysis_fig4-11.png|Figure 1]] is a schematic diagram showing a series of cross sections representing the four phases of Late Triassic to Early Cretaceous evolution of the GOM basin (see [[:file:sedimentary-basin-analysis_fig4-6.png|Figure 2]] for the location).

[[:file:sedimentary-basin-analysis_fig4-11.png|Figure 1A]] consists of Late Triassic to Early Jurassic rifting along linear zones within brittle crust with deposition of synrift nonmarine sediments and volcanics within half-grabens.

[[:file:sedimentary-basin-analysis_fig4-11.png|Figure 1D]] of Early Cretaceous age is characterized by broad carbonate platforms rimmed by reef buildups along the margins established at the boundary of differential subsidence between thin and thick crust. Fine-grained carbonates were deposited in the adjacent deep basin. Terrigenous clastics continued to be input at local points along the northern margin. Known and potential reservoirs occur within both carbonate and clastic depositional systems of these early Cretaceous rocks.
