The most important red-bed and salt sequences in Mexico are Jurassic and are located in eastern Mexico in or around the Gulf of Mexico. Most of these rocks are Middle Jurassic, and they are overlain almost always by evaporitic sequences that mark the beginning of the Middle Jurassic transgressive sequence. In some places, they overlie pre-Jurassic rocks. Mesozoic red-bed sequences have recently been dated with organic and inorganic components of palynological residues.
Information from red-bed sequences in the Los San Pedros Allogroup and Huayacocotla Group (Rhaetic-Liassic age in the Huayacocotla–El Alamar Basin), La Joya Formation (Middle Jurassic age in the Sabinas Subbasin), Rosario and Cahuasas Formations (Middle Jurassic age in the Tampico-Misantla Sub-basin), and Todos Santos Formation (Middle Jurassic age in the Veracruz and Tabasco-Chiapas-Campeche Subbasins) allows us to construct a model for the origin and evolution of the Gulf of Mexico. The model includes three different stages: (1) the formation of one (or two?) Rhaetic-Early Liassic wrench or shear basin(s) (Huayacocotla–El Alamar Basin) related to the evolution of the Pacific convergent system; (2) formation of the Tampico-Misantla Sub-basin during the late Liassic as a result of the southwest displacement of the Huayacocotla and Tlaxiaco Blocks along the Tampico–Lázaro Cárdenas and Teziutlán-Acapulco Megashears; and (3), the origin during the Middle Jurassic of the Gulf of Mexico Basin and the Sabinas, Veracruz, and Tabasco-Chiapas-Campeche Mexican petroleum subbasins as a result of the development of a triple junction. This triple junction allowed the northwestward displacement of the Texas-Louisiana block and the western region of Mexico from the stable Chiapas-Tabasco-Campeche-Yucatán block along the Lewis Clark–Bahamas and Texas-Boquillas-Sabinas lineaments and the Pico de Orizaba–Laguna Inferior Megashear.

The Circum-Gulf of Mexico and the Caribbean: Hydrocarbon Habitats, Basin Formation and Plate Tectonics
The Circum-Gulf of Mexico and the Caribbean has long been one of the world's most important petroleum provinces, as well as one of the world's most geologically complex regions. These two characteristics have resulted in an extensive amount of ongoing research by both industry and academia. AAPG Memoir 79, The Circum-Gulf of Mexico and the Caribbean, is the first volume in more than a decade to document such a wide range of research on the geology of this vast area. Of the total 44 papers, roughly two-thirds pertain to the Gulf of Mexico, with an emphasis on the Mexican portion of the basin, and to the petroliferous areas of the southern Caribbean, including Colombia, Venezuela, Cuba, and Trinidad and Tobago. The remaining papers relate to the Antilles and Central America, as well as a series of papers that address region-wide topics such as plate tectonic evolution. A significant number of papers were contributed by authors from national oil companies and universities from within the region.
