The Delaware Geological Survey (DGS) has published a new geologic map of the Millsboro and Whaleysville areas in central Sussex County titled Geologic Map of the Millsboro and Whaleysville Quadrangles, Delaware.

Geologic Map 20 presents the results of research by Kelvin W. Ramsey and Jaime Tomlinson of DGS.

The map illustrates and describes the geologic units found at the land surface and in the shallow subsurface in the map area. The purpose of the map is to provide geologic information that can be used to define the underlying geology of the study area, in support of regulatory land-use decision making, delineation and protection of water resources, and to identify potential sand and gravel resources.

When used in conjunction with supporting subsurface geologic information, the map can be used to aid in locating water supplies for public, domestic, agricultural, and industrial use, for mapping groundwater recharge areas, and for protecting groundwater and surface water resources in parts of Sussex County.

The map contains detailed descriptions and ages of all units presented on the map as well as cross sections that show the geology and names of units underlying the units exposed at the land’s surface.

The map is part of the Delaware Geological Survey’s ongoing mission to understand geologic and hydrologic systems and to advise, inform, and educate Delawareans about the results of such investigations for use in issues regarding surface and groundwater resources, agriculture, economic development, land-use planning, environmental protection, resource evaluation, engineering applications, hazard identification and mitigation, and recreation.

DGS Geologic Map No. 20 is available as a PDF to view online or as a downloadable product from the DGS web page.
