Hydrocarbon exploration in a Cenozoic sedimentary succession in the southeastern Gulf of Mexico highlights the importance of high resolution biostratigraphy to understand the geological setting of this complicated area. Calcareous nannofossil, planktonic foraminifera and palynomorph data from six wells in the Macuspana Basin, define chronostratigraphic intervals. Graphic correlation method and sequence stratigraphy allow the construction of a detailed chronostratigraphic framework.

Subsurface sections in this basin represent deep to shallow marine environments which reveal basinward and landward facies shifts related mainly to sea level changes. Graphic correlation helps delineate stratigraphic sequences, while sequence stratigraphic key surfaces cause predictable patterns in the graphic correlation of biostratigraphic data. Integration of graphic correlation and sequence stratigraphy from the six wells reveals an erosional unconformity separating the Pliocene and Miocene strata.
