Sequence stratigraphic analysis is being applied in the Gulf Coast to facilitate genetic interpretations of stratigraphy and to improve predictions of reservoir facies. Among the components of sequences, the condensed section is of paramount importance in providing a chronostratigraphic framework and in the delineation of systems tracts. Condensed sections are characterized by abundant and species diverse planktonic foraminiferal and calcareous nannoplankton assemblages, along with fine-grained pelagic to hemipelagic lithologies often rich in authigenic minerals such as glauconite and siderite. In deep-water environments, condensed sections correspond to sea-level highstands and are temporally equivalent to both the maximum flooding surface in the transgressive systems tracts and the highstand systems tracts on the shelf. This paper discusses various methods and techniques for recognizing and graphically displaying condensed sections, and defines and documents 16 condensed sections in the Gulf Coast pre-Wisconsin Plio-Pleistocene that have currently been identified.
