Theme Session 19

Sequence Stratigraphy and Biostratigraphy of Pennsylvanian-Lower Permian Cyclothems in the North American Midcontinent

Gregory P. Wahlman, BP America
Philip H. Heckel, University of Iowa

This session will present recent developments and advances in sequence stratigraphic and biostratigraphic analyses of the classic Pennsylvanian-Lower Permian cyclothems of the North American midcontinent. It will further provide the opportunity to integrate the new information into a more comprehensive picture of the stratigraphic history and correlation of the cyclothems, and to observe and compare the effects of high frequency sealevel fluctuations on the evolution and distribution of various fossil groups.
