Lithogeochemical Character of Near-Surface Bedrock in the New England Coastal Basins
Entry ID: USGS_ofr02-007_lithogeo

[ Update this Record ]

Abstract: The lithogeochemical data layer was compiled to provide the NECB NAWQA study
area with digital geologic information that could be used in the analysis of
surface- and ground-water quality. Goals of the NAWQA program are to describe
the status and trends of a large representative part of the Nation's surface-
and ground-water resources and to identify the natural and human factors that
affect the ... View entire text

Quality The spatial accuracy of the geologic source information varies. The source
geologic map scales range from 1:100,000 to 1:500,000. In addition, analysis
near State boundaries may be limited by the geologic map interpretation
differences across State boundaries. Interpretations combining the NECB NAWQA
data set with a similar bordering data set done for the CONN NAWQA (Robinson
and others, 1999) are limited by variances related to differences in source
materials used and interpretation of geologic information between the CONN and
NECB lithochemical mapping.
