Abstract
Rising and highstands of sea level during the middle to late Pleistocene deposited swamp to nearshore sediments along
the margins of an ancestral Delaware Bay, Atlantic coastline, and tributaries to an ancestral Chesapeake Bay. These deposits
are divided into three lithostratigraphic groups: the Delaware Bay Group, the Assawoman Bay Group (named herein), and the
Nanticoke River Group (named herein). The Delaware Bay Group, mapped along the margins of Delaware Bay, is subdivided
into the Lynch Heights Formation and the Scotts Corners Formation. The Assawoman Bay Group, recognized inland of
Delaware’s Atlantic Coast, is subdivided into the Omar Formation, the Ironshire Formation, and the Sinepuxent Formation.
The Nanticoke River Group, found along the margins of the Nanticoke River and its tributaries, is subdivided into the Turtle
Branch Formation (named herein) and the Kent Island Formation.
