POST-MIOCENE STRATIGRAPHY AND MORPHOLOGY, OUTER COASTAL PLAIN, SOUTHEASTERN VIRGINIA.
YALE UNIV NEW HAVEN CONN
Detailed geologic mapping subsurface stratigraphic study of post-Miocene sediments east of the Suffolk Scarp and Nansemond River in southeastern Virginia show that older morphostratigraphic concepts are erroneous. Instead of two terraces, with one terraceformation of offshore marine origin beneath each, a complex of formations is present, in some cases with three to five formations underlying a single flat area previously designated a terrace. The present study revises earlier work based on inadequate stratigraphic information, and thereby serves as a stratigraphic basis for future Atlantic Coastal Plain studies of post-Miocene sediments east of the Suffolk Scarp.
