The geology of an area of 660 square miles mostly in the northeastern corner of Tennessee and small adjacent areas in Virginia and North Carolina is the subject of this report. The region lies principally in the Unaka province, with extensions northwestward into the Appalachian Valley and southwestward into the Blue Ridge province. The report combines results of surveys made between 1941 and 1953 by the U. S. Geological Survey, the Tennessee Division of Geology, and the Tennessee Valley Authority, and is published in cooperation with the Tennessee Division of Geology. Northeasternmost Tennessee is a region of widespread mineralization and was formerly important for mineral production. Iron, manganese, and bauxite...
Local folding in brown sandstone below coals, three miles east of Salt Wells, north side of Union Pacific track, direction east. T. 20 N., R. 102 W. Almond quadrangle. Sweetwater County, Wyoming. 1907.
Anticline in nugget sandstone on South Piney Creek, T. 29 N., R. 115 W. Viola quadrangle. Lincoln County, Wyoming. 1906.
Rugged topography north of Hoback River, T. 36 N., R. 115 W. Red beds of Carboniferous white sandstone. Cheney quadrangle. Lincoln County, Wyoming. 1906.
Burned coal or clinker responsible for butte-like topography. The buttes are capped by clinker, baked sandstone, and shale. T. 43 N., R. 72 W. Bulle quadrangle. Wyoming. No date.
The U.S. Geological Survey (USGS) has compiled a geodatabase containing mineral-related geospatial data for the People's Republic of China. The data can be used in analyses of the extractive fuel and nonfuel mineral industries and related economic and physical infrastructure integral for the successful operation of the mineral industries within the area of study as well as the movement of mineral products across domestic and global markets. This geodatabase reflects the USGS ongoing commitment to its mission of understanding the nature and distribution of global mineral commodity supply chains by updating and publishing the georeferenced locations of mineral commodity production and processing facilities, mineral...
Baked clay and sandstone over burned bed of coal in the upper burned beds east of Will Wright's old ranch on Hay Creek. T. 43 N., R. 72 W. 4 quadrangle. Wyoming. No date.
This collection consists of samples of the Entrada Sandstone and Pony Express Limestone from the Placerville vanadium-uranium district in southwest Colorado. The samples were collected under the direction of Harry Granger to compare some of the geochemical attributes of the Placerville district deposits to the more widespread Salt Wash hosted deposits. These samples were also used by George Breit for research to determine an age of the roscoelite (V-illite). Samples are stored in fabric bags in cardboard boxes on one wood pallet.
The Blue Ridge belt in northwestern North Carolina and northeastern Tennessee is composed chiefly of 1,000-million to 1,100-million-year-old metamorphic and plutonic rocks that have been thrust many miles northwestward across unmetamorphosed Cambrian(?) and Cambrian sedimentary rocks of the Unaka belt. The Blue Ridge thrust sheet is rooted on the southeast along the Brevard zone, a zone of strike-slip faulting along which metamorphic and plutonic rocks of the Inner Piedmont belt are juxtaposed with rocks of the Blue Ridge. Near the southeastern edge of the Blue Ridge belt, the Blue Ridge thrust sheet is breached by erosion, and the rocks beneath are exposed in the Grandfather Mountain window, which is 45 miles long...
Overturned anticline on South Piney Creek, T. 29 N., R. 115 W. Note the talus slope of nugget sandstone and the rapid turn of the nugget sandstone near center of picture. Viola quadrangle. Lincoln County, Wyoming. 1906.
Cliff of Topman's Gulf, Jefferson County, New York. Lorraine Rocks. Utica shale with interbedded Sandstone of the Lorraine Series coming in above. Jefferson County, New York. 1889.

This digital dataset was created as part of a U.S. Geological Survey hydrologic resource assessment and development of an integrated numerical hydrologic model of the hydrologic system of the Upper Colorado River Basin, an extensive region covering approximately 412,000 square kilometers in five states: Wyoming, Colorado, Utah, Arizona, and New Mexico. As part of this larger study, the USGS developed this digital dataset of geologic data and a three-dimensional hydrogeologic framework model (3D HFM) that define the elevation, thickness, and extent of seven hydrogeologic units in the Upper Colorado River Basin. The hydrogeologic setting of the Colorado Plateau consists of thick Paleozoic, Mesozoic, and Cenozoic aquifers,...

Sheep herders' monument near south end of Aspen Mountain showing quartzite sandstones. T. 17 N., R. 104 W. Maxon quadrangle, Wyoming. No date.
Brown Upper Jurassic sandstone, a typical phase in southern Wayne County near Notom Ranch. Wayne County, Utah. 1921.
