GM19 Geologic Map of the Frankford and Selbyville Quadrangles, Delaware

GM19 Geologic Map of the Frankford and Selbyville Quadrangles, Delaware
Publication Type:
Geologic Map
Publication Date:
Dec 2013
Authors:
Tomlinson, J.L., Ramsey, K.W., Andres, A.S.
Abstract:

The geological history of the surficial units of the Frankford and Delaware
portion of the Selbyville Quadrangles was the result of deposition of the Beaverdam
Formation during the late Pliocene and its subsequent modification by erosion and
deposition related to sea-level fluctuations during the Pleistocene. The geology at the
land surface was then further modified by periglacial activity that produced dune deposits
in the map area. Surficial geologic mapping was conducted using field maps at a scale of
1:12,000 with 2 foot contours. Stratigraphic boundaries drawn at topographic breaks
reflect detailed mapping using contours not shown on this map.
