A chronostratigraphic framework was developed as a prelude to a regional sequence stratigraphic and associated systems tracts analysis of the offshore Louisiana and Texas Miocene. The integrated data base for this study included over 10,000 line mi of seismic data, 230 wireline logs, and detailed biostratigraphic analyses on 35 wells. The objective of the study was to map systems tracts and facies that may help delineate prospective areas. Because they are a fundamental stratigraphic unit within a sequence, this framework emphasizes condensed sections and their calibration by microfossil highest occurrence datums. Condensed sections have been delineated utilizing planktonic foraminiferal and calcareous nannofossil abundance and species diversity patterns, as well as detailed paleo-water depth determinations based on benthic foraminiferal biofacies. Pitfalls in the use of condensed sections may arise in shallow paleoshelf settings where datums may be unreliable, and in deeper environments where multiple abundance/diversity peaks may occur. However, an event stratigraphic scheme is generally the most satisfactory method for overcoming correlation problems inherent in the Gulf Coast unstable prograding shelf margin.
