[[:file:sedimentary-basin-analysis_fig4-10.png|figure 1]] shows the Gulf of Mexico region as it looked approximately 130 Ma. Note the spreading and transform fault systems separating the North American, Atlantic, Farallon, and Caribbean plates. Striped areas are cratonic basement; shading is transitional to oceanic basement; and arc-related volcanics are noted by a “A” pattern east of the Farallon/Caribbean trench.
