  ABSTRACT: Mineral resource surveys indicate that much of the area has 
            inferred low-grade iron resources that occur in folded 
            sedimentary rocks of Paleozoic age. Other mineral resources 
            include rocks suitable for crushed stone, quartzite suitable for 
            high-silica uses; limestone suitable for agricultural purposes, 
            and shale suitable for structural clay products. A potential for 
            natural gas may exist but cannot be quantified from present 
            knowledge.

            Sugarloaf Mountain quadrangle; United States; Virginia
  ABSTRACT: The quadrangles include portions of the Blue Ridge and Valley 
            and Ridge provinces. Drainage changes were involved in the 
            origin of Natural Bridge. Stratigraphy ranges from the 
            Precambrian Virginia Blue Ridge Complex to the Devonian Brallier 
            Formation, and relationships are complicated by imbricate thrust 
            sheets and faulted folds. Precambrian and Lower Cambrian units 
            moved westward along several thrusts, narrowing the Appalachian 
            Valley until, in the Buchanan area, Precambrian and Silurian are 
            less than 2 1/2 miles apart. In the Arnold Valley area, a window 
            in the Precambrian exposes Middle Cambrian Erwin and Shady 
            Formations. In the southwest, Cambrian units are west of ridge-
            forming Silurian and Devonian rocks, a displacement of over 
            eight miles. Limestone, dolomite, and clay are being produced at 
            present, and iron and manganese have been mined in the past.
