This map, originally produced by the U.S. Geological Survey, will no longer be printed by the USGS. The NCGS will print a copy of the map from a scanned image.
The mineral resources of the Charlotte 1x2 degree quadrangle, North Carolina and South Carolina, were assessed between 1978 and 1982 under the Conterminous United States Mineral Assessment Program. The mineral-resource assessments were made on the basis of geologic and geophysical investigations, the presence of existing or abandoned mines, mapped mineral occurrences, and where appropriate, on heavy-mineral occurrences seen in pan concentrates or detected by geochemical analysis of pan concentrates. Map size appoximately 42"x28".
