content: Mines Chert, also known as Bedford County, is an oolitic chert. It is light gray to medium gray with clear and black oolites with black being the most prominent. It becomes white with occasional iron staining and a coriaceous cortex when weathered. The chert has many ooid inclusions. The texture is very coarse, with angular fracturing, outer surface iron stains and roughness caused by dolomitic cortex. Deposits include platy and residuum.
