Delaware Geological Survey releases geologic map of Frankford, Selbyville area
Date
The Delaware Geological Survey (DGS) has published a new geologic map of the Frankford and Selbyville area in eastern Sussex County titled Geologic Map of the Frankford and Selbyville Quadrangles, Delaware.
GM19 Geologic Map of the Frankford and Selbyville Quadrangles, Delaware
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
GM18 Geologic Map of the Bethany Beach and Assawoman Bay Quadrangles, Delaware
The geologic history of the surficial units of the Bethany Beach and Assawoman Bay Quadrangles is that of deposition of the Beaverdam Formation and its subsequent modification by erosion and deposition related to sea-level fluctuations during the Pleistocene. The geology reflects this complex history onshore, in Indian River Bay and Assawoman Bay, and offshore in the Atlantic Ocean.
Celebrate Geologic Map Day 2012!
Date
Friday, October 19th has been designated Geologic Map Day 2012. As an extension of the National Cooperative Geologic Mapping Program of USGS, Geologic Map Day focuses the attention of students, teachers, and the general public on the study, uses, and significance of geologic maps for education, science, business, and a variety of public policy concerns.
GM17 Geologic Map of the Harbeson Quadrangle, Delaware
The complex geologic history of the surficial units of the Harbeson Quadrangle is one of deposition of the Beaverdam Formation and its subsequent modification by erosion and deposition related to sea-level fluctuations during the Pleistocene. The geology is further complicated by periglacial activity that produced dune deposits and Carolina Bays scattered throughout the map area.
