Split-spoon samples of six drill cores 0 to 60 feet deep within 2,800 acres from
the Pinehurst Formation, Richmond County, North Carolina, were evaluated for
glass sand raw material potential. The Pinehurst Formation, as mapped on the 1985
Geologic Map of North Carolina, covers approximately 120,660 acres in Richmond,
Scotland, Moore and Hoke counties. Commercial glass sand has been produced from
a nearby site from the Pinehurst Formation. By R. Mensah-Biney, L.A. Carpenter, J.W. Miller, Jr., and J.C. Reid, 2005.
