55 Sequence Stratigraphic, Geochemical, and Geochronologic Correlation of the Cenomanian-Turonian Ocean Anoxic Event 2 (OAE2) in the Cretaceous Western Interior Seaway (KWIS) and the Gulf Coast

The Cenomanian-Turonian Ocean Anoxic Event 2 (OAE2) is a global event, however its stratigraphic, geochemical, and geochronologic records are locally quite variable. This session will correlate the OAE2 records in the Cretaceous Western Interior Seaway (KWIS) and the Gulf Coast.
