Abstract: | The Gulf of Mexico basin occupies a vast region encompassing the southern continental margin of North America, a considerable part of the Greater Antilles, and the intervening Sigsbee Deep with the oceanic crust. In the north, the basin is contiguous with spurs of the Hercynian Appalachians, the Mississippi Interior and Permian basins. The Mississippi Fan, one of the largest in the world, governs the bottom topography and structure in the eastern Gulf of Mexico. The abyssal basin is surrounded in many areas by steep continental slopes passing in places into escarpments: Sigsbee, Campeche, and others. It is only in the Yucatan Peninsula region that the continental slope merges with a wide shelf. The Cuban-North Haiti meganticlinorium frames the basin on the Cuba Island side. |
