Abstract

The structure of the Caribbean region testifies to the extremely unstable condition of the terrestrial crust of this intercontinental and simultaneously interoceanic area. In the recent geological epoch, the Caribbean region is represented by a series of structural elements, the main of which are the Venezuelan and Colombian deep-sea suboceanic depressions, the Nicaraguan Rise, and the Greater and Lesser Antilles bordering the Caribbean Sea in the north and east. There are 63 sedimentary basins in the entire Caribbean region. However, only the Venezuelan and Colombian basins, the Miskito Basin in Nicaragua, and the northern and eastern shelves of the Antilles, Paria Bay, Barbodos-Tobago, and Grenada basins are promising in terms of oil-and-gas bearig. In the Colombian Basin, the southwestern part, located in the rift zone of the Gulf of Uraba, is the most promising. In the Venezuelan Basin, possible oil-and-gas-bearing basins showing little promise are assumed to be in the northern and eastern margins. The main potential of the eastern Caribbean region is attributed to the southern margin, at the shelf zone of which are the Tokuyo-Bonaire, Tuy-Cariaco, Margarita, Paria Bay, Barbados–Tobago, and Grenada oil-and-gas-bearing basins. The rest of the deepwater depressions of the Caribbean Sea show little promise for hydrocarbon research due to the small thickness of the deposits, their flat bedding, and probably a lack of fluid seals.
