Lawson Adit
The Lawson Adit is a horizontal mine tunnel, or adit, on the UC Berkeley campus, near the Hearst Mining Building, dug directly through the Hayward Fault. Started in 1916, the adit is named after Andrew Lawson, one-time Dean of the College of Mining at UC Berkeley. History The adit was dug under the direction of Frank H. Probert, who had just previously been appointed Professor of Mining. It was dug primarily for instructional purposes, with secondary hopes that it would represent a new source of water for the campus. Much of the equipment to dig and use the tunnel was donated by the mining industry in the San Francisco Bay area. Although an initial report said that it was to go 1,800 feet into the Berkeley Hills, the actual construction resulted in a mine tunnel of about 200 feet. Between 1919 and 1930 the adit was used to give mining and metallurgy students hands-on training, specifically to provide "sound, practical training in drilling, drifting, blasting, timbering, and mi ...

George Louderback
George Davis Louderback (April 6, 1874 – January 27, 1957) was an American geologist, known for identifying and describing benitoite and joaquinite. Biography Louderback was born in San Francisco, and received an A.B. from the University of California, Berkeley in 1896, followed by a Ph.D. in 1899. He married Clara Augusta Henry on October 3, 1899. He was a teaching assistant in mineralogy at UC Berkeley in 1897–1900 and then taught at the University of Nevada in 1900–1906. At UC Berkeley's department of geology, Louderback became an assistant professor in 1906, an associate professor in 1907, and a full professor in 1917. In Nevada, Louderback studied the geological structure of the Great Basin, especially of the Basin ranges, and Nevada's gypsum deposits. He did research on the Mesozoic formations of southern Oregon, the relation of radioactivity to vulcanism, the glaucophane of the Pacific Coast Ranges, and the stratigraphy of Mount Diablo.

History Of Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and f ...

Berkeley Seismological Laboratory
The Berkeley Seismological Laboratory (BSL) is a research lab at the Department of Geology at the University of California, Berkeley. It was created from the Berkeley Seismographic Stations, a site on the Berkeley campus where Worldwide Standard Seismographic Network instruments were first deployed in 1959. Today, BSL's mission is to "support fundamental research into all aspects of earthquakes, solid earth processes, and their effects on society". An experimental early warning system developed by BSL issued a warning 10 seconds before the 6.0 magnitude earthquake that hit the Napa region on August 24, 2014. Such a warning system could potentially give people time to take cover in the event of a quake, preventing injuries caused by falling debris, automatically stopping trains or shutting off gas lines. The system, developed in conjunction with the United States Geological Survey (USGS), the California Institute of Technology and the University of Washington, will eventually cove ...

Mélange
In geology, a mélange is a large-scale breccia, a mappable body of rock characterized by a lack of continuous bedding and the inclusion of fragments of rock of all sizes, contained in a fine-grained deformed matrix. The mélange typically consists of a jumble of large blocks of varied lithologies. Both tectonic and sedimentary processes can form mélange. Mélange occurrences are associated with thrust faulted terranes in orogenic belts. A mélange is formed in the accretionary wedge above a subduction zone. The ultramafic ophiolite sequences which have been obducted onto continental crust are typically underlain by a mélange. Smaller-scale localized mélanges may also occur in shear or fault zones, where coherent rock has been disrupted and mixed by shearing forces. Large-scale melanges formed in active continental margin settings generally consist of altered oceanic crustal material and blocks of continental slope sediments in a sheared mudstone matrix. The mixing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stern Hall (Berkeley)
Stern Hall is an all-female residence hall at the University of California, Berkeley, constructed and operated by the University. It was built in 1942 on a $258,000 grant from Rosalie Meyer Stern, daughter of Marc Eugene Meyer and widow of Sigmund Stern, class of 1879. It is the sister hall to Bowles Hall, the all-male residence on campus. The Hall was first opened for 90 undergraduate women; currently it houses approximately 267. It is located at Hearst Avenue and Highland Place. The Building The Hall was designed by William Wurster, the former dean of the College of Environmental Design. The building has four floors comprising single, double and triple occupancy rooms, with a limited number of suites. Bathrooms are either single-sex or co-ed; all males must announce themselves when entering the co-ed bathrooms. In 1959, a new wing, adding room for 47 more residents, was completed. A second wing was added in 1981. Stern Hall has a number of notable features: an original Diego Riv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seismologist
Seismology (; from Ancient Greek σεισμός (''seismós'') meaning "earthquake" and -λογία (''-logía'') meaning "study of") is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. It also includes studies of earthquake environmental effects such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, glacial, fluvial, oceanic, atmospheric, and artificial processes such as explosions. A related field that uses geology to infer information regarding past earthquakes is paleoseismology. A recording of Earth motion as a function of time is called a seismogram. A seismologist is a scientist who does research in seismology. History Scholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletus (c. 585 BCE), Anaximenes of Miletus (c. 550 BCE), Aristotle (c. 340 BCE), and Zhan ...

Adit
An adit (from Latin ''aditus'', entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins. Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining. Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advantage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
