North Carolina Geochemical Atlas

from National Uranium Resource Evaluation (NURE) stream sediment data

North Carolina Geological Survey (NCGS)

In 1991, the North NCGS first published (revised in 1993) a paper-bound geochemical atlas of North Carolina based on the NURE program’s stream sediment sample data. Since that time, interactive web services have made the distribution of information to an end-user in digital media more readily accessible and available. Also, since that time the U.S. Geological Survey (USGS), as the NURE database custodian, has made corrections to the database.

The NCGS has made the NURE stream sediment data available via an interactive web platform for North Carolina. In addition to the analyte first-order statistics, the NURE program data for each tested analyte at all sample points in the state can be found in the map's companion documentation (NCGS Bulletin 99). Also available are descriptions for each analyte, describing the analytes relevance to North Carolina, to help guide the users’ understanding of the sample data.

As with all large databases, decisions were made to best manage the distribution of the information. Explanations behind some of those decisions are documented in NCGS Bulletin 99. Using a blend of symbologies (graduated colors and proportional symbol sizes) for each of the available analytes based on the NURE sample data, analyte concentration map figures can be found in the appendix of NCGS Bulletin 99.
