“…The grade of the hematitic sandstone ranges widely from 10 to 28 percent iron, but a weighted average for all samples is about 18 percent iron (Lesure, 1982;Jones and others, 1982, p. 19) which compares well with data on similar rock from Giles County, Va. (Fish, 1967, p. 10;Lesure and others, in press). Using the geologic map of the Dolly Ann area (Lesure, 1981), we can estimate • that 8 the Rose Hill is exposed in about 2,700 acres (1,090 ha), is covered by 5-200 ft (1.5-60 m) .Pf younger rock in 2,800 acres {1,130 118}, and is .covered by more than 200 ft (60 m) in 1,~00 acres (530 ha) (fig. 4).…”
