Subcropping Geology for the Mid-Atlantic Coastal Plain

U.S. Geological Survey 2005 Subcropping Geology for the Mid-Atlantic Coastal Plain Version 1.0, September 27, 1999 Vector coverage USGS Professional Paper USGS PP 1680 Reston, VA U.S. Geological Survey http://water.usgs.gov/lookup/getspatial?pp1680_sbcrps Subcropping geology for the Mid-Atlantic Coastal Plain was compiled and interpreted from available published sources. Formation contacts were interpolated across unmapped areas. Inconsistencies in nomenclature, interpretation, and scale were resolved to the extent possible, although some remain because of differences in mapping resolution among different areas. For more information, see U. S. Geological Survey Professional Paper 1680. This data set was developed to compile a map of aquifer subcrop areas in the Mid-Atlantic Coastal Plain using currently available geologic mapping. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ArcInfo format, this metadata file may include some ArcInfo-specific terminology. 2005 Current as of publication date.
