Ralph J. Roberts (geologist)
Ralph Jackson Roberts (1911–2007) was an American geologist and research scientist with the USGS. He is credited with the discovery of the Carlin and Battle Mountain Gold Belts, which make up the richest gold-mining region in Nevada as well as the United States. Early life Roberts grew up in eastern Washington, and earned his bachelor's and master's degrees from the University of Washington in Seattle. His PhD research, which he conducted at Yale University, defined the Antler orogeny, a major mountain-building episode in the late Paleozoic. USGS work During World War II Roberts lived in Central America, where he had been sent to discover and conduct fundamental research on strategic minerals. After the war he returned to the United States; for the next 40 years he worked in Nevada and Utah, deciphering the geologic history of major mountain ranges and exploring mineral deposits. In 1960, Roberts published a paper that predicted the existence of important mineral-bearing roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Washington Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

Yale University Alumni
Yale University is a private research university in New Haven, Connecticut. Established in 1701 as the Collegiate School, it is the third-oldest institution of higher education in the United States and among the most prestigious in the world. It is a member of the Ivy League. Chartered by the Connecticut Colony, the Collegiate School was established in 1701 by clergy to educate Congregational ministers before moving to New Haven in 1716. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first PhD in the United States in 1861 and organizing as a university in 1887. Yale's faculty and student populations grew after 1890 with rapid expansion of the physical campus and scientific research. Yale is organized into fourteen constituent schools: the original undergraduate colleg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gold Mining In Nevada
Gold mining in Nevada, a state of the United States, is a major industry, and one of the largest sources of gold in the world. In 2018 Nevada produced , representing 78% of US gold and 5.0% of the world's production. Total gold production recorded from Nevada from 1835 to 2017 totals , worth US$322.6 billion at 2020 values. Much of Nevada's gold production comes from large open pit mining using heap leaching recovery. The Nevada mining industry supported an average 14,787 direct employees in 2018, with about 75,000 additional jobs related to providing goods and services needed by the mining industry. The average pay for mining industry employees during this time was $97,600 per year, the third highest average private employment sector in the state. Major mining companies such as Newmont Goldcorp and Barrick Gold Corporation operate many of the state's gold mines. Active mines include those at Jerritt Canyon and the Carlin Trend. Although Nevada was known much more for silver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Livermore
John Sealy Livermore (April 16, 1918 – February 7, 2013) was an American geologist who discovered or helped to discover four major gold deposits in northern Nevada. Livermore was born in San Francisco, California, and was descended from a pioneer California family with roots in Maine. An ancestor, Elijah Livermore, built a grist mill and a saw mill on the Androscoggin River in 1791. The town of Livermore Falls, Maine, is named after him. His great-grandfather, Horatio Gates Livermore, came to California from Maine during the Gold Rush in 1850, and later became a California State Senator from Eldorado County. His great-grandfather and his grandfather, Horatio Putnam Livermore, who came to California in 1856, used their Maine mill experience to become involved in the earliest days of hydroelectric power, helping to build the original Folsom Dam. His father, Norman Banks Livermore was a founding board member of Pacific Gas and Electric. His mother, Caroline Sealy Liver ...

Carlin Trend
The Carlin Unconformity or Carlin Trend is a geologic feature in northeastern Nevada which represents a period of erosion or non-deposition likely associated with a collision between a tectonic crustal block called a terrane and the North American Plate. The collision occurred during the Mississippian Period, about 350 million years before present. The collision is associated with the Antler Orogeny. The collision induced higher crustal temperatures and pressures which produced numerous hot springs along the suture zone. Several episodes of subsurface magmatism are known to have occurred subsequent to the collision, associated with tectonic forces affecting the entire Basin and Range Province. During each of these episodes, and particularly during the Eocene epoch, hot springs brought dissolved minerals toward the surface, precipitating them out along fissures. Among these minerals were gold and silver. The Carlin Gold trend is one of the world's richest gold mining districts. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autobiography
An autobiography, sometimes informally called an autobio, is a self-written account of one's own life. It is a form of biography. Definition The word "autobiography" was first used deprecatingly by William Taylor in 1797 in the English periodical ''The Monthly Review'', when he suggested the word as a hybrid, but condemned it as "pedantic". However, its next recorded use was in its present sense, by Robert Southey in 1809. Despite only being named early in the nineteenth century, first-person autobiographical writing originates in antiquity. Roy Pascal differentiates autobiography from the periodic self-reflective mode of journal or diary writing by noting that " utobiographyis a review of a life from a particular moment in time, while the diary, however reflective it may be, moves through a series of moments in time". Autobiography thus takes stock of the autobiographer's life from the moment of composition. While biographers generally rely on a wide variety of documents an ...
