Excerpt from Explanatory Text for Geologic Map of North Carolina

Counties into Virginia. The rocks of the two belts are very similar and consist of red, brown, purple and gray claystone, Shale, sandstone, conglomerate and fanglomerate, and some coal.

The eastern one half of the State is underlain by sedimentary deposits that range from Upper Cretaceous to Recent in age. These sediments are commonly referred to as the Coastal Plain deposits and consist largely of unconsolidated sediments that include gravels, sands, clays, limestone and marls. The deposits of the Coastal Plain form a wedge-shaped block of sediments that increases in thickness from a feather edge along its western border to approximately feet at Cape Hatteras. The sedi ments rest unconformably on crystalline rocks of Precambrian age.
