Revision of the Plio-Pleistocene Cycles and Their Application to Sequence Stratigraphy and Shelf and Slope Sediments in the Gulf of Mexico
WORNARDT, WALTER W., JR., Micro-Strat Inc., Houston, TX, and PETER R. VAIL,* Rice University, Houston, TX
The age, correlation, and cycles in the Pliocene and Pleistocene have been debated for decades. The Pliocene-Pleistocene sequence chronostratigraphy presented in this paper is based on data obtained from more than 100 wells in the Gulf of Mexico. This high-resolution biostratigraphic data, well log sequence stratigraphy interpretations, and their correlation (50 wells) to the seismic record sections through a two-way-time log or synthetic seismogram permits the Pliocene and Pleistocene Series to be divided into 14 fourth-order sequences and three third-order sequences. We have discussed and illustrated the most important events that have led up to this detailed revision of the Plio-Pleistocene.
