Uramphite

	Uramphite Uramphite is a rarely-found phosphate mineral in the "phosphate, arsenate and vanadate" mineral class with chemical composition (NH4)2 O2PO4sub>2·6H2O from which it is seen to be a hydrated ammonium uranyl The uranyl ion is an oxycation of uranium in the oxidation state +6, with the chemical formula . It has a linear structure with short U–O bonds, indicative of the presence of multiple bonds between uranium and oxygen. Four or more ligands ... phosphate. Uramphite crystallizes in the tetragonal crystal system and develops rectangular crystal faces approximately 0.2 mm wide, but is also found as rosette-like mineral aggregates and surface films. The mineral is translucent a colored light to bottle-green or light yellow with a shiny lustre (mineralogy), lustre on the exterior. Etymology and history Uramphite was discovered in 1950 in the uranium-coal-mineral vein, bed "Tura-Kaffak" near Minkush in the Moldo Too mountains in Naryn, Kyrgyzstan. Analysis and public ...

picture info	Phosphate Mineral Phosphate minerals contain the tetrahedrally coordinated phosphate (PO43−) anion along sometimes with arsenate (AsO43−) and vanadate (VO43−) substitutions, and chloride (Cl−), fluoride (F−), and hydroxide (OH−) anions that also fit into the crystal structure. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common. Applications Phosphate rock has high concentration of phosphate minerals, most commonly of the apatite group. It is the major resource mined to produce phosphate fertilizers for the agriculture sector. Phosphate is also used in animal feed supplements, food preservatives, anti-corrosion agents, cosmetics, fungicides, ceramics, water treatment and metallurgy. The largest use of minerals mined for their phosphate content is the production of fertilizer. Phosphate minerals are often used for control of rust and prevention of corrosion on ferrous materials applied with electrochemical conver ...

picture info	Bottle-green Varieties of the color green may differ in hue, chroma (also called saturation or intensity) or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a green or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below. Computer web color greens Green The color defined as ''green'' in the RGB color model is the brightest green that can be reproduced on a computer screen, and is the color named ''green'' in X11. It is one of the three primary colors used in the RGB color space along with red and blue. The three additive primaries in the RGB color system are the three colors of light chosen such as to provide the maximum range of colors that are capable of being represented on a computer or television set. This color is also called ''regular green''. It is at precisely 120 degrees on the HSV color wheel, also known as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Coal Coal is a combustible black or brownish-black sedimentary rock, formed as stratum, rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Heinrichite Heinrichite is a monoclinic-prismatic containing arsenic, barium, hydrogen, oxygen, and uranium. The mineral is named after Eberhardt William Heinrich (1918–1991) who first noted it in 1958 in the U.S. State of Oregon. Description Heinrichite is radioactive pale green, pale yellow mineral. Heinrichite fluoresces light-green in longwave and shortwave ultraviolet. Because of its uranium Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly ... content, the mineral is radioactive. References {{phosphate-mineral-stub Uranium(VI) minerals Arsenate minerals ...

picture info	Autunite Autunite (hydrated calcium uranyl phosphate), with formula Ca(UO2)2(PO4)2·10–12H2O, is a yellow-greenish fluorescent phosphate mineral with a hardness of 2–. Autunite crystallizes in the orthorhombic system and often occurs as tabular square crystals, commonly in small crusts or in fan-like masses. Due to the moderate uranium content of 48.27% it is radioactive and also used as uranium ore. Autunite fluoresces bright green to lime green under UV light. The mineral is also called calco-uranite, but this name is rarely used and effectively outdated. Autunite was discovered in 1852 near Autun, France, which is also autunite's namesake. It occurs as an oxidation product of uranium minerals in granite pegmatites and hydrothermal deposits. Associate minerals include metaautunite, torbernite, phosphuranylite, saleeite, uranophane and sabugalite. Etymology Autunite was named after the town of Autun, France, where the mineral was initially found. The mineral was named by Henry ...

	Grandfathering A grandfather clause, also known as grandfather policy, grandfathering, or grandfathered in, is a provision in which an old rule continues to apply to some existing situations while a new rule will apply to all future cases. Those exempt from the new rule are said to have grandfather rights or acquired rights, or to have been grandfathered in. Frequently, the exemption is limited, as it may extend for a set time, or it may be lost under certain circumstances; for example, a grandfathered power plant might be exempt from new, more restrictive pollution laws, but the exception may be revoked and the new rules would apply if the plant were expanded. Often, such a provision is used as a compromise or out of practicality, to allow new rules to be enacted without upsetting a well-established logistical or political situation. This extends the idea of a rule not being retroactively applied. Origin Southern United States The term originated in late nineteenth-century legislation and ...

	International Mineralogical Association Founded in 1958, the International Mineralogical Association (IMA) is an international group of 40 national societies. The goal is to promote the science of mineralogy and to standardize the nomenclature of the 5000 plus known mineral species. The IMA is affiliated with the International Union of Geological Sciences (IUGS). The Association supports the activities of Commissions and Working Groups involved on certain aspects of mineralogical practice and facilitates interactions among mineralogists by sponsoring and organising meetings. In particular, the IMA holds its general meeting every four years. The next meeting is scheduled in 2022 in Lyon, France. Presidents The presidents of the IMA have been: * since 2021: Anhuai Lu ** Peking University 2018–2020: Patrick Cordier (born 1961) * Université de Lille 2016–2018: Peter C.
