Subcropping Geology for the Mid-Atlantic Coastal Plain These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. 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.

This was developed as part of an effort to map standardized, terrestrial ecosystem distributions for the nation using a classification developed by NatureServe (Comer and others, 2003). This ecosystem mapping methodology, which delineates ecosystems by mapping and integrating their major structural components, was first developed for South America (Sayre and others, 2008) and is now being implemented globally (Sayre and others, 2007). Surficial lithology strongly influences the differentiation and distribution of terrestrial ecosystems, and is one of the key input...
