Ilirney Range
The Ilirney Range (russian: Илирнейский кряж) is a range of mountains in Chukotka Autonomous Okrug, Russian Far East. Administratively the range is part of Bilibino District. The village of Ilirney is located southwest of the central area of the range. Bilibino is located to the west of the western end.Google Earth Geography The highest point of the Ilirney Range is high mount Dvukh Tsirkov (гора Двух Цирков, meaning "Two Circuses"). Other high peaks of the range are high mount Sypuchiy Kamen (Сыпучий Камень) and high mount Radialnaya (радиальная). To the southeast of the mountain range rises the Anyuy Range, to the west it borders with the Kyrganay and Chuvanay ranges, to the north with the Rauchuan Range and to the east with the Anadyr Plateau. The Ilirney Range is part of the East Siberian System of mountains and is one of the subranges of the Anadyr Highlands. Two beautiful lakes are located below the southern slopes ...

Tellurate
In chemistry tellurate is a compound containing an oxyanion of tellurium where tellurium has an oxidation number of +6. In the naming of inorganic compounds it is a suffix that indicates a polyatomic anion with a central tellurium atom.Nomenclature of Inorganic Chemistry IUPAC Recommendations 2005 – Full text (PDF) Tellurium oxyanions Historically the name tellurate was only applied to oxyanions of tellurium with +6, formally derived from , and the name |
Hexagonal Minerals
In geometry, a hexagon (from Greek , , meaning "six", and , , meaning "corner, angle") is a six-sided polygon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°. Regular hexagon A '' regular hexagon'' has Schläfli symbol and can also be constructed as a truncated equilateral triangle, t, which alternates two types of edges. A regular hexagon is defined as a hexagon that is both equilateral and equiangular. It is bicentric, meaning that it is both cyclic (has a circumscribed circle) and tangential (has an inscribed circle). The common length of the sides equals the radius of the circumscribed circle or circumcircle, which equals \tfrac times the apothem (radius of the inscribed circle). All internal angles are 120 degrees. A regular hexagon has six rotational symmetries (''rotational symmetry of order six'') and six reflection symmetries (''six lines of symmetry''), making up the dihedral group D6. The longest diagonals of a regular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manganese(III) Minerals
Manganese is a chemical element with the symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide. Manganese is also an essential human dietary element, important in macronutrient metabolism, bone formation, and free radical defense systems. It is a critical component in dozens of proteins and enzymes. It is found mostly in the bones, but also the liver, kidneys, and brain. In the human brain, the manganese is bound to manganese metalloproteins, most notably glutamine synthetase in astrocytes. Manganese was first isolated in 1774. It is familiar in the laboratory in the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc Minerals
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It is the seco ...

Magnesium Minerals
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray metal having a low density, low melting point and high chemical reactivity. Like the other alkaline earth metals (group 2 of the periodic table) it occurs naturally only in combination with other elements and it almost always has an oxidation state of +2. It reacts readily with air to form a thin passivation coating of magnesium oxide that inhibits further corrosion of the metal. The free metal burns with a brilliant-white light. The metal is obtained mainly by electrolysis of magnesium salts obtained from brine. It is less dense than aluminium and is used primarily as a component in strong and lightweight alloys that contain aluminium. In the cosmos, magnesium is produced in large, aging stars by the sequential addition of three helium nuclei to a carbon nucleus. When such stars explode as supernovas, much of the magnesium is expelled into the interstellar medi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zemannite
Zemannite is a very rare oxide mineral with the chemical formula Mg0.5ZnFe3+[TeO3]3·4.5H2O. It crystallizes in the hexagonal crystal system and forms small Prism (geometry), prismatic brown crystals. Because of the rarity and small crystal size, zemannite has no applications and serves as a collector's item. History and etymology Zemannite was discovered in 1961 in a tellurium deposit near Moctezuma, Sonora, Mexico as an unnamed new mineral. It was not accepted then by the International Mineralogical Association (IMA) due to the uncertainty in its chemical composition. The mineral structure was solved in 1967 by Eckhart Matzat as is specified. Two years later, the mineral was recognized by the IMA under the name zemannite, in honor of the Austrian mineralogist Josef Zemann (born 1923), who had worked extensively on tellurium minerals.E.
