Mineral resources of the Charlotte 1 degree by 2 degrees Quadrangle, North Carolina and South Carolina

Abstract

This report is the product of a 4-year project of the U.S. Geological Survey (USGS) under the Conterminous United States Mineral Assessment Program (CUSMAP). Data on geology, mineral-deposit occurrences, geochemistry, heavy minerals, and geophysics available in September 1981 have been integrated into a multidisciplinary analysis of the mineral-resource potential of the quadrangle. In addition, the relative importance of different commodities of the area is evaluated from records of past production through 1978. The results of CUSMAP for the Charlotte quadrangle are presented here and in related map reports of the U.S. Geological Survey. Stone, sand and gravel, clay, and 17 types of metallic and other nonmetallic mineral deposits are evaluated. Commodities produced from these deposits at the present time or in the past, or those judged potentially available, are base metals (copper, lead, and zinc), gold, silver, lithium, tin, beryllium, iron, thorium (monazite), rare earths, zirconium, barite, sulfur, feldspar, mica, corundum, kyanite and sillimanite, quartz, and rutile.
