The Deep River coal field of North Carolina occurs in sandstone and shale of Triassic age, which crop out in a comparatively narrow belt from Oxford near the northern border of the state to the South Carolina line. Coal has been reported at many places in the belt, but the only known coal of commercial importance is found on Deep River, west and northwest of Sanford.
