Deposits referable to this formation are said to occur throughout the
extent of the Atlantic and Gulf Coastal Plains as far as the Rio Grande.
In North Carolina it forms a terrane 40 or 50 miles wide on the Roanoke
and: extends southward through the Carolinas in a broad zone. In
Virginia and the Carolinas the deposits are said to lie at elevations of
between 25 and 250 feet above tide. As regards its age, the formation is
Said to correspond roughly with the Pliocene.
