The Cretaceous sedimentary sequence at Punta Gorda in southern Belize corresponds only partially to the known stratigraphic column of the Maya Block. In addition to dolomites and anhydrites of the Coban Formation (Aptian-Santonian), rudist-bearing shallow-water carbonates of the Campur Formation (Campanian-Maastrichtian), and the siliciclastic flysch sequence of the Sepur Formation (Maastrichtian-Eocene), pelagic limestones and limestones of debris-flow origin are present at Punta Gorda. They are of Berriasian-Valanginian and Aptian-Albian ages. Today, they are thrust onto dolomites of the Coban Formation and shales of the Sepur Formation.
The pelagic limestones are similar in age and lithology to the sedimentary sequence of southwestern Cuba and suggest a common depositional area on the eastern margin of the Maya Block in the Proto-Caribbean Basin.

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.
