Figure F4. Summary stratigraphic section for Omar Formation (Pleistocene), Beaverdam Formation (upper? Miocene to Pliocene?), Bethany formation (upper? Miocene to Pliocene?), and upper Manokin formation (upper Miocene) from the Bethany Beach borehole. This, and subsequent similar figures, summarizes core recovery, lithology, gamma ray log signature, age, environments, and sequence stratigraphic interpretations. (Continued on next page.)
