Matlockite
Matlockite is a rare lead halide mineral, named after the town of Matlock in Derbyshire, England, where it was first discovered in a nearby mine. Matlockite (chemical formula: PbFCl) gives its name to the matlockite group which consists of rare minerals of a similar structure. Description The mineral, a lead fluorochloride (formula PbFCl), was discovered sometime around the early 1800s at Bage Mine at Bolehill near Matlock, together with specimens of phosgenite and anglesite. Although phosgenite was known at this time, it seems likely that matlockite itself remained unappreciated as a new mineral for some fifty years. It was given the name by Greg in 1851. The first mention of matlockite may have been in Mawe's ''Mineralogy of Derbyshire'' in 1802 in which he gives a detailed description of phosgenite, which is then followed by a mention of a mineral he refers to as "glass lead" – a description which does rather equate to the appearance of matlockite. It is a light, translu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiger, Arizona
Tiger is a Unincorporated area, former populated place in Pinal County, Arizona, Pinal County in the U.S. state of Arizona. The town was settled as Schultz ''circa'' 1881 in what was then the Arizona Territory, then later reestablished as Tiger after World War I. History The area that was to become Tiger was first settled in 1881 after Frank Schultz located gold ore in what was to become the Mammoth Mine. The camp that settled around the mining, mine took the name Schultz, and a post office was established under that name on July 12, 1894. Since water, needed for refinement of ore, was not present near the mine, a mill was established away on the west bank of the San Pedro River (Arizona), San Pedro River, in a town that came to be known as Mammoth, Arizona, Mammoth, after the mine and the mill. The ore was hauled to the mill by way of mule teams, until just after the start of the 20th century when an aerial tram was completed between the Mammoth Mine and the Mammoth Mill. As ...

Paralaurionite
Paralaurionite is a colorless mineral consisting of a basic lead chloride PbCl(OH) that is dimorphous with laurionite. It is a member of the matlockite group. The name is derived from para-, the Greek for "near", and laurionite, because of its polymorphic relationship to it. Bright, yellow tips of thorikosite can form on paralaurionite crystals and paralaurionite may also be intergrown with mendipite. Occurrence It was first described in 1899 for an occurrence in slag in Laurium, Attica, Greece. In 1952 an occurrences of it was reported from the Mammoth Mine, Arizona. It occurs in lead bearing slag which has been exposed to seawater. It also occurs in polymetallic ore deposits. It occurs associated with laurionite, penfieldite, fiedlerite, phosgenite in slag deposits; and with leadhillite, matlockite, cerussite, hydrocerussite, diaboleite Diaboleite is a blue-colored mineral with formula Pb2CuCl2(OH)4.

Bismoclite
Bismoclite is a bismuth oxohalide mineral with formula BiOCl. It is the naturally occurring form of bismuth oxychloride. The name was derived from its chemical constituents. It is a secondary bismuth mineral first thought to be composed of bismuthyl ions (BiO+) and chloride anions, however, the existence of the diatomic bismuthyl ion is doubtful. It is a member of the matlockite group. It was first described in 1935 from alluvium near bismuth-bearing pegmatites in South Africa. It has been found in association with granite pegmatite and in greisen. Associated minerals include bismutite, mica, jarosite, alunite, cerussite, atacamite, connellite. Occurrences include the type locality at Jackals Water, SW of Prieska, South Africa; Bygoo, Australia; the Tintic district in the East Tintic Mountains of Utah; and from Dalbeattie, Scotland. Crystal structure The crystal structure of bismoclite was found to be composed of linked decahedrons, specifically a square antiprism. These d ...

Zavaritskite
Zavaritskite is a rare mineral of the halide class, bismuth oxyhalide with the chemical formula (BiO)F. It is named after the Soviet geologist and petrographer, academician of the USSR Academy of Sciences Alexander Nikolaevich Zavaritsky. It was discovered in 1962 by Soviet scientists. Zavaritskite is part of matlockite group of minerals. Description Zavaritskite is a gray mineral with a greasy or semi-metallic luster; opaque, only slightly translucent in very small grains. The mineral powder is finely dispersed, colorless. The crystallization process of zavaritskite occurs in a square system, due to which the mineral forms sufficiently fine-grained powder cryptocrystalline aggregates. The mineral is usually found together with bismuth, topaz, fluorite and others in the oxidized zone of the Sherlovaya Gora, Sherlovogorsky deposit in Transbaikal. Zavaritskite was first described in 1962 by Soviet scientists E. I. Dolomanova, V. M. Senderova, and M. T. Yanchenko. It is one of the ox ...

Phosgenite
Phosgenite is a rare mineral consisting of lead carbonate chloride, (PbCl)2CO3. The tetragonal crystals are prismatic or tabular in habit: they are usually colorless and transparent, and have a brilliant adamantine lustre. Sometimes the crystals have a curious helical twist about the tetrad or principal axis. The hardness is 3 and the specific gravity 6.3. The mineral is rather sectile, and consequently was earlier known as corneous lead, (German ''Hornblei''). Name and occurrence The name phosgenite was given by August Breithaupt in 1820, after phosgene, carbon oxychloride, because the mineral contains the elements carbon, oxygen, and chlorine. It was found associated with anglesite and matlockite in cavities within altered galena in a lead mine at Cromford Cromford () is a village and civil parish in Derbyshire, England, in the valley of the River Derwent between Wirksworth and Matlock. It is north of Derby, south of Matlock and south of Matlock Bath. Cromford i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laurionite
Laurionite (PbCl(OH)) is a lead halide mineral. It forms colorless to white crystals in the orthorhombic crystal system and is dimorphous with paralaurionite, both members of the matlockite group. It was first described in 1887 for an occurrence in the Laurium District, Attica, Greece, and named after the town Laurium. It occurs as an oxidation product in lead ore deposits, and is also produced on lead-bearing slag by reaction with saline solutions. It occurs associated with paralaurionite, penfieldite, fiedlerite, phosgenite, cerussite and anglesite Anglesite is a lead sulfate mineral with the chemical formula PbSO4. It occurs as an oxidation product of primary lead sulfide ore, galena. Anglesite occurs as prismatic orthorhombic crystals and earthy masses, and is isomorphous with barite and ....

John Mawe
John Mawe (1764 – 26 October 1829) was a British mineralogist who became known for his practical approach to the discipline. Biography Mawe was born in Derby in 1764 to Samuel Maw(e). His mother died when he was ten and he was raised by his father's second wife, Francis (born Beigton). In early life he appears to have spent fifteen years at sea. In 1790, he became captain of the merchant vessel ''Trent'', trading to St Petersburg. In 1793, Mawe was apprenticed to the Derby mason Richard Brown (1736–1816), and married his daughter, Sarah, on 1 November 1794. Brown & Mawe was the name of the retail business near Covent Garden in 1797 which sold objects created from Derbyshire marble at the factory in Derby. Mawe was manager of this business. This business was established in 1794. Geological diagrams of Derbyshire strata which are made from Derbyshire minerals were once thought to have all been created by White Watson but it is now thought likely that some of these objects in D ...

Minerals In Space Group 129
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid substance with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.John P. Rafferty, ed. (2011): Minerals'; p. 1. In the series ''Geology: Landforms, Minerals, and Rocks''. Rosen Publishing Group. The geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or organic compounds in the sense of chemistry (such as mellite). Moreover, living organisms often synthesize inorganic minerals (such as hydroxylapatite) that also occur in rocks. The concept of mineral is distinct from rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral or may be an aggregate of two or more different types of minerals, spacially segregated into distinct phases. Some ...

Tetragonal Minerals
In crystallography, the tetragonal crystal system is one of the 7 crystal systems. Tetragonal crystal lattices result from stretching a cubic lattice along one of its lattice vectors, so that the Cube (geometry), cube becomes a rectangular Prism (geometry), prism with a square base (''a'' by ''a'') and height (''c'', which is different from ''a''). Bravais lattices There are two tetragonal Bravais lattices: the primitive tetragonal and the body-centered tetragonal. The body-centered tetragonal lattice is equivalent to the primitive tetragonal lattice with a smaller unit cell, while the face-centered tetragonal lattice is equivalent to the body-centered tetragonal lattice with a smaller unit cell. Crystal classes The point groups that fall under this crystal system are listed below, followed by their representations in international notation, Schoenflies notation, orbifold notation, Coxeter notation and mineral examples.Hurlbut, Cornelius S.; Klein, Cornelis, 1985, ''Ma ...

Lead Minerals
Lead () is a chemical element; it has symbol Pb (from Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the group, lead tends to bond with itself; it can form chains and polyhe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
