Analyses and description of geochemical samples, Craggy Mountain Extension, Buncombe County, North Carolina

Semiquantitative spectrographic analyses for 31 elements and atomic—absorption analyses for gold and zinc on 6 bulk stream sediments, 20 soil, and 19 rock samples from the Craggy Mountain Extension area and vicinity, Buncombe County, North Carolina, are reported here in detail. Locations for all samples are given in Universal Transverse Mercator (UTM) coordinates. Brief descriptions of rock samples are also included. Rocks analyzed include mica—garnet—kyanite schist, mica—quartz gneiss, vein quartz, and amphibolite. The data contain no obviously anomalous values that might be related to mineralized rock.

Mineral resources of the Mill Creek, Mountain Lake, and Peters Mountain Wilderness Study Areas, Craig and Giles counties, Virginia and Monroe County, West Virginia

The Mill Creek, Mountain Lake, and Peters Mountain Wilderness Study Areas comprise about 8200 ha of steep wooded slopes in the Jefferson National Forest in west central Virginia and adjacent West Virginia. Mill Creek area contains about 1800 ha and Peters Mountain area about 1600 ha in Giles County, Va. Mountain Lake area contains about 3000 ha in Giles County, a little more than 570 ha in Craig County, Va., and nearly 1230 ha in Monroe County, W. Va. A small part of each study area is privately owned-- about 5 percent of Mill Creek, 20 percent of Mountain Lake and 2 percent of Peters Mountain. The U.S. Forest Service owns the mineral rights on all the Government land except for about 162 ha in the Peters Mountain arca. The three study areas are in the western part of the Valley and Ridge physiographic province and are therefore part of the folded Appalachians, which contain deformed sedimentary rocks of Paleozoic age. The same elastic marine and non—marine sedimentary rock formations ranging in age from Late Ordovician to Middle Devonian are exposed throughout the region. Sandstones of the Juniata, Tuscarora, and Keefer Formations form cliffs, ridges and steep dip slopes. The distinctive hematitic sandstone beds of the Rose Hill Formation cover any dip slopes with red sandstone blocks. Other formations are less well exposed and form lower slopes and valleys.

Analyses and description of soil samples from Mountain Lake and Peters Mountain Wilderness Study areas, Virginia and West Virginia

Semiquantitative emission spectrographic analyses for 30 elements and atomic absorption analysis for zinc on 98 soil samples are reported here in detail. Location for all samples are in Universal Transverse Mercator (UTM) coordinates. A few samples of soil developed on Lower Devonian sandstone and chert contain more barium and zinc than soils on other formations but do not suggest the occurrence of economic concentrations of either element.

Analyses and description of geochemical samples, Peters Mountain Wilderness Study Area, Giles County, Virginia

Semiquantitative emission spectrographic analyses for 64 elements on 43 stream sediment and 73 rock samples from Peters Mountain Wilderness Study area, Giles County, Virginia, are reported here in detail. Locations for all samples are in Universal Transverse Mercator (UTM) coordinates. Brie[ descriptions of rock samples are also included. Rocks analysed are mostly sandstone. Samples of hematitic sandstone of the Rose Hill Formation and limonite-cemented sandstone of the Rocky Gap Sandstone contain high values of iron; these rocks are submarginal iron resources. Some of the same iron-rich samples have a little more barium, copper, cobalt, lead, silver, and/or zinc then average sandstone, but they do not suggest the presence of economic deposits of these metals. No other obviously anomalous values related to mineralized rock are present in the data.

Mineral resources of the Craggy Mountain Wilderness Study Area, Buncombe County, North Carolina

The Craggy Mountain Wilderness Study Area covers about 550 hectares of the Pisgah National Forest in the Blue Ridge Mountains of western North Carolina (fig. 1). The area is 21 km northeast of Asheville, Buncombe County, N.C., and 11 km southwest of Mount Mitchell, the highest point in eastern North America. The study area is bounded on the southeast by the Blue Ridge Parkway, on the northeast by Bullhead Ridge, and on the southwest and west by Big Fork Ridge (Plate 1b). It includes all of the Craggy Mountain scenic area established by the Forest Service in 1961 and some additional land west of Bearwallow Branch and along the middle part of Carter Creek for a short distance beyond the mouth of Peach Orchard Creek.

Mineral resources of the Cranberry Wilderness Study Area, Pocahontas and Webster counties, West Virginia

Cranberry Wilderness Study Area comprises 14,702 ha in the Monongahela National Forest, Pocahontas and Webster Counties, east-central West Virginia. The area is in the Yew Mountains of the Appalachian Plateaus and is at the eastern edge of the central Appalachian coal fields. Cranberry Glades, a peatland of botanical interest lies at the southern end of the study area. All surface rights in the area are held by the U. S. Forest Service; nearly 90 percent of the mineral rights are privately-owned or subordinate to the surface rights.

Analyses and description of geochemical samples, Craggy Mountain Wilderness Study area, Buncombe County, North Carolina

Semiquantitative spectrographic analyses for 30 elements and atomic absorption analyses for gold and zinc on 24 bulk stream sediments, 22 panned concentrates, and 50 rock samples from the Craggy Mountain Wilderness Study area and vicinity, Buncombe County, North Carolina, are reported here in detail. Locations for all samples are given in Universal Transverse Mercator (UTM) coordinates. Brief descriptions of rock samples are also included. Rocks analyzed include mica-garnet-kyanite schist, mica-quartz gneiss, vein quartz, pegmatite, trondhjemite and amphibolite. The data contain no obviously anomalous values that might be related to mineralized rock.
