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, translucent cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matlock, Derbyshire
Matlock is the county town of Derbyshire, England. It is situated in the south-eastern part of the Peak District, with the National Park directly to the west. The town is twinned with the French town of Eaubonne. The former spa resort of Matlock Bath lies immediately south of the town on the A6. The civil parish of Matlock Town had a population in the 2011 UK census of 9,543. Matlock is nine miles (14 km) south-west of Chesterfield and in easy reach of the cities of Derby (19 miles), Sheffield (20 miles) and Nottingham (29 miles); the Greater Manchester conurbation is 30 miles away. Matlock is within the Derbyshire Dales district, which also includes the towns of Bakewell and Ashbourne, as well as Wirksworth. The headquarters of Derbyshire County Council are in the town. History The name Matlock derives from the Old English ''mæthel'' (or ''mæðel''), meaning assembly or speech, and ''āc'', meaning oak tree; thus Matlock means 'moot-oak', an oak tree where meetings ...

Bolehill, Derbyshire
Bolehill is an area of Wirksworth, Derbyshire, England. It is located in the north of the town and has connections to the lead mining industry. Originally a village in its own right, Bolehill became part of the outskirts of Wirksworth upon the town's expansion during the 19th and 20th centuries. Bolehill is adjacent to Black Rocks, a local landmark and a short walk from the High Peak Trail at Middleton incline. History Bolehill has a history as a mining and small-holding settlement, one of the very few mining villages to spring up during the 18th and 19th centuries in the Peak District. By the 1841 census there were 637 inhabitants living in the village, 77 out of 209 workers being employed in lead mining. Bagshaw’s directory of 1848 calls the Bage “the most productive mine in the District”. 17th and 18th century references to Bage Mine, Wall Close Mine (to the North) and Hollyhole Grove Mine (to the West) can be found among the Wooley Manuscripts.

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 In ge ...

Phosgenite
Phosgenite is a rare mineral consisting of lead chlorocarbonate, (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, from 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, near Matlock: hence its common name cromfordite.

Tiger, Arizona
Tiger is a former populated place in 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 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, in a town that came to be known as 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 the tram's construction neared completion, and the need for the town waned, the Schultz post off ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Derbyshire
Derbyshire ( ) is a ceremonial county in the East Midlands, England. It includes much of the Peak District National Park, the southern end of the Pennine range of hills and part of the National Forest. It borders Greater Manchester to the north-west, West Yorkshire to the north, South Yorkshire to the north-east, Nottinghamshire to the east, Leicestershire to the south-east, Staffordshire to the west and south-west and Cheshire to the west. Kinder Scout, at , is the highest point and Trent Meadows, where the River Trent leaves Derbyshire, the lowest at . The north–south River Derwent is the longest river at . In 2003, the Ordnance Survey named Church Flatts Farm at Coton in the Elms, near Swadlincote, as Britain's furthest point from the sea. Derby is a unitary authority area, but remains part of the ceremonial county. The county was a lot larger than its present coverage, it once extended to the boundaries of the City of Sheffield district in South Yorkshire where it cov ...

Minerals In Space Group 129
In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound 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 Geology, geological definition of mineral normally excludes compounds that occur only in living organisms. However, some minerals are often biogenic (such as calcite) or are 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 (geology), 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 (geology), aggregate of two or more different types of m ...

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 becomes a rectangular 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 base-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, ''Manual of Mineralogy'', 20th ed., p ...

Lead Minerals
Lead is a chemical element with the symbol Pb (from the 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 toxic, even in small amounts, especially to children. 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, le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 oxidation products ...
