Midwayan (Paleocene) pollen correlations in the Eastern United States

The Midwayan Stage of the eastern United States is divided into three new pollen zones, the Pseudoplicapollis serena, Tricolpites asper and Caryapollenites prodromus interval zones, which can be correlated among composite sections for the northern Mississippi Embayment, eastern Gulf Coast, southern Atlantic Coastal Plain and middle Atlantic Coastal Plain, except where missing by unconformity. Pollen data support the presence of an unconformity between the Rhems and Williamsburg Formations of South Carolina. The base of the Aquia Formation of Virginia and Maryland is slightly younger than the top of the Naheola Formation of Alabama. The Midwayan-Sabinian stage boundary is probably of late NP5 age and is probably only slightly younger than the important range base of Carya
