ABSTRACT
The Eocene-Miocene contact in the Delaware coastal plain should be moved down and placed below the pebbly, glauconitic sand of the uppermost Piney Point Formation (Jacksonian age). The uppermost part of the Piney Point Formation (glauconitic greensand), which is pebbly, lacks a characteristic late Eocene fauna and contains middle Miocene Foraminifera, unquestionably making this pebbly sand Miocene in age. Thus, a new correlation can be drawn on the basis of the microfossils, rather than on the green color due to the presence of glauconite.
