Abstract: Presence of Stratigraphic Traps in the Back Arc Basins of the Southern Shelf of Cuba

Rodobaldo Rodriguez, Rene Dominguez, Sonia Touset

For the last ten years the southern shelf of Cuba has been the object of seismic investigations, mainly in the Ana Maria and Guacanayabo areas. More than 4000 km of seismic lines with 3000 % had been shot. These seismic surveys had confirmed the following geological events:

1. Presence of back arc extensional basins as a result of the ocean-ocean subduction. These basins started to form since Middle Cretaceous;

2. Presence of sedimentary sequences which change in thickness between 3.0-7.0 km;

3. Predominance of the extensional regime since Middle Cretaceous with subsidence, accommodation and extending of the sediments;

4. Development of stratigraphic traps, mainly associated with reef facies and slope fans of Late Cretaceous-Early Tertiary.
