Sphalerite is a sulfide mineral with the chemical formula (Zn,Fe)S. It is the most important ore of zinc. Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative, Mississippi-Valley type, and volcanogenic massive sulfide deposits. It is found in association with galena, chalcopyrite, pyrite, calcite, dolomite, quartz, rhodochrosite, and fluorite.
Norris Dam is a hydroelectric and flood control structure located on the Clinch River in Anderson County and Campbell County, Tennessee, United States. The dam was the first major project for the Tennessee Valley Authority, which had been created in 1933 to bring economic development to the region and control the rampant flooding that had long plagued the Tennessee Valley. The dam was named in honor of Nebraska Senator George Norris (1861–1944), a longtime supporter of government-owned utilities in general, and supporter of TVA in particular. The infrastructure project was listed on the National Register of Historic Places in 2016.
The Driftless Area, a region in the American Midwest, comprises southwestern Wisconsin, southeastern Minnesota, northeastern Iowa, and the extreme northwestern corner of Illinois. It was never covered by ice during the last ice age, and therefore lacks glacial deposits, also termed drift. Its landscape is characterized by steep hills, forested ridges, deeply carved river valleys, and karst geology with spring-fed waterfalls and cold-water trout streams. Ecologically, the Driftless Area's flora and fauna are more closely related to those of the Great Lakes region and New England than those of the broader Midwest and central Plains regions. The steep riverine landscape of both the Driftless Area proper and the surrounding Driftless-like region are the result of early glacial advances that forced preglacial rivers that flowed into the Great Lakes southward, causing them to carve a gorge across bedrock cuestas, thereby forming the modern incised upper Mississippi River valley. The region has elevations ranging from 603 to 1,719 feet at Blue Mound State Park, and together with the Driftless-like region, covers 24,000 square miles (62,200 km2).
Bean Station is a town in Grainger and Hawkins counties in the state of Tennessee, United States. As of the 2020 census, the population was 2,967.
The Southeast Missouri Lead District, commonly called the Lead Belt, is a lead mining district in the southeastern part of Missouri. Counties in the Lead Belt include Saint Francois; Crawford; Dent; Iron; Madison: Reynolds; and Washington. Philip Francois Renault of France led a large exploratory mission in 1719 and started mining operations in Old Mines and Mine La Motte in 1720. The town of Sainte Genevieve was founded as a river port for transportation of lead out of the area. Moses Austin started large-scale mining and smelting at Potosi, originally known as Mine a Breton, and founded Herculaneum as his shipping point on the Mississippi. This lead was originally used as a roofing material. Bonne Terre has large subterranean mines, now used commercially for recreational scuba diving.
Clinch Mountain is a mountain ridge in the U.S. states of Tennessee and Virginia, lying in the ridge-and-valley section of the Appalachian Mountains. From its southern terminus at Kitts Point, which lies at the intersection of Knox, Union and Grainger counties near Blaine, Tennessee, it runs in a generally east-northeasterly direction to Garden Mountain near Burke's Garden, Virginia. It separates the Clinch River basin, to the north, and the Holston River basin, to the south.
Washburn is an unincorporated community in rural northern Grainger County, Tennessee, United States. It is part of both the Knoxville Metropolitan Statistical Area and the Morristown Metropolitan Statistical Area. According to the 2000 United States census, the total population of Washburn was 2,508.
The Geology of Pennsylvania consists of six distinct physiographic provinces, three of which are subdivided into different sections. Each province has its own economic advantages and geologic hazards and plays an important role in shaping everyday life in the state. They are: the Atlantic Coastal Plain Province, the Piedmont Province, the New England Province, the Ridge and Valley Province, the Appalachian Plateau Province, and the Central Lowlands Province.
New Jersey is a very geologically and geographically diverse region in the United States' Middle Atlantic region, offering variety from the Appalachian Mountains and the Highlands in the state's northwest, to the Atlantic Coastal Plain region that encompasses both the Pine Barrens and the Jersey Shore. The state's geological features have impacted the course of settlement, development, commerce and industry over the past four centuries.
Copper mining in the United States has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017 the United States produced 1.27 million metric tonnes of copper, worth $8 billion, making it the world's fourth largest copper producer, after Chile, China, and Peru. Copper was produced from 23 mines in the US. Top copper producing states in 2014 were Arizona, Utah, New Mexico, Nevada, and Montana. Minor production also came from Idaho, and Missouri. As of 2014, the US had 45 million tonnes of known remaining reserves of copper, the fifth largest known copper reserves in the world, after Chile, Australia, Peru, and Mexico.
Silver mining in the United States began on a major scale with the discovery of the Comstock Lode in Nevada in 1858. The industry suffered greatly from the demonetization of silver in 1873 by the Coinage Act of 1873, known pejoratively as the "Crime of 73", but silver mining continues today.
Uranium mining in Colorado, United States, goes back to 1872, when pitchblende ore was taken from gold mines near Central City, Colorado. The Colorado uranium industry has seen booms and busts, but continues to this day. Not counting byproduct uranium from phosphate, Colorado is considered to have the third largest uranium reserves of any US state, behind Wyoming and New Mexico.
Loyston is a ghost town in Union County, Tennessee, United States, that was inundated by the waters of the Clinch River after the completion of Norris Dam in 1936. Established in the early 19th century around a foundry built by its namesake, John Loy, over subsequent decades the community's location along State Highway 61 helped it grow into a trading center for local farmers. By the time the Tennessee Valley Authority (TVA) began making plans to build Norris Dam in the early 1930s, Loyston had a population of approximately 70 residents, and consisted of a post office and several small businesses.
Joppa is an unincorporated community in rural central-western Grainger County, Tennessee, United States. It rests below Joppa Mountain, a subrange located near the southern terminus of the 150 mile (240 km) long Clinch Mountain ridge complex, offering views of five U.S. States and the Great Smoky Mountains. Joppa is part of the Morristown, Tennessee Metropolitan Statistical Area, and also a component of the Knoxville-Morristown-Sevierville Combined Statistical Area.
Embreeville is an unincorporated community in southern Washington County, Tennessee. It is located along the Nolichucky River and on State Routes 81 and 107.
The Shady Dolomite is a geologic formation composed of marine sedimentary rocks of early Cambrian age. It outcrops along the eastern margin of the Blue Ridge province in the southeastern United States and can be found in outcrops in the states of Alabama, Georgia, Tennessee, North Carolina, and Virginia. It is also can be found in the subsurface of Kentucky, Ohio, and West Virginia. The Shady is predominantly composed of dolostone and limestone with lesser amounts of mudrock. It contains fossils of trilobites, archaeocyathids, algae, brachiopods, and echinoderms, along with the enigmatic fossil Salterella. The Shady Dolomite was first described by Arthur Keith in 1903 and was named for exposures in the Shady Valley of Johnson County in the state of Tennessee. Near Austinville, Virginia, the Shady hosts ore deposits that have been mined extensively for lead and zinc ore.
Zinc mining in the United States produced 780,000 tonnes of zinc in 2019, making it the world's fourth-largest zinc producer, after China, Australia, and Peru. Most US zinc came from the Red Dog mine in Alaska. The industry employed about 2,500 in mining and milling, and 250 in smelting.
