Previous studies of the Pungo River Formation have been confined mostly to Beaufort County, where the phosphate contained in these strata attains maximum concentration and thickness, and where it is nearest the surface. This paper presents the results of a study of the attitude and configuration, lithologic variations, and structural relationships of the rocks of the entire early and middle Miocene section, throughout their extent in North Carolina as shown on figure 1. The heavy line on the figure indicates the westward limit of the main body of early and middle Miocene rocks. The isolated patches in Beaufort, Jones, and Onslow Counties represent ero-sional remnants or outliers. Includes 10 plates. By James A. Miller, 1982. 32 pages.
