Abstract (Summary)

The regional stratigraphy of the lowest Paleocene and Eocene in southern Louisiana was reinterpreted. Well logs, paleontology, and seismic data were used to determine the formations of the Upper Cretaceous through Eocene. The primary focus of this study was to determine the morphology of an erosional paleo-canyon in the Paleocene-Eocene Wilcox Group in southern Louisiana. There are several known canyons in the Wilcox Group around the Gulf of Mexico, which were used as analogues for this study. Cross sections were created and used in conjunction with regional structure and isochore maps to determine the structure and shape of the paleo-canyon, and a synthetic seismogram was generated to help identify formations on the available NW-SW trending 2D seismic line. The regional maps were then compared with the seismic data in order to gain a better understanding of the Wilcox paleo-canyon. Well control was very limited in this area, and some projections had to be made; therefore, paleontological data and analogues were used to help explain the paleo-canyon's origin. The principle two theories of submarine canyon creation in the Gulf of Mexico revolve around whether the canyon was carved by sub-aerial or submarine erosion. It is believed that this canyon was possibly initiated in a sub-aerial environment and later modified by submarine conditions.
