Lake Zabuye
Zabuye Lake is a hypersaline, landlocked soda lake located at an elevation of in the Shigatse Prefecture of Tibet Autonomous Region, from Lhasa. The lake gives its name to the mineral zabuyelite (lithium carbonate, Li2CO3), which was discovered here in 1987 and has been mined since 2004–2005. In 2008, the salt mine at the lake was regarded as the major source of lithium in China. Etymology The name of Zabuye Lake is also spelt as Drangyer, Zabayu, Zhabuye, Chabyêr or Chabyer, Tabie or Tchapia sometimes with an addition of "Tsaka" or "caka", which means "salt lake" in Tibetan. Geography and geology The lake is located in the Gangdise Mountains (also known as the Lunggar Mountains) deep in the Tibetan Plateau. It is one of 251 salt lakes in Tibet. It is divided into the northern (98 km²) and the southern (149 km²) sub-basins, which are linked by a narrow channel. The southern part is semi-dry and appears white in satellite images. The northern part is fed from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tibetan Plateau
The Tibetan Plateau, also known as the Qinghai–Tibet Plateau or Qingzang Plateau, is a vast elevated plateau located at the intersection of Central Asia, Central, South Asia, South, and East Asia. Geographically, it is located to the north of Himalayas and the Indian subcontinent, and to the south of Tarim Basin and Mongolian Plateau.

Standard Tibetan
Lhasa Tibetan or Standard Tibetan is a standardized dialect of Tibetan spoken by the people of Lhasa, the capital of the Tibetan Autonomous Region. It is an official language of the Tibet Autonomous Region. In the traditional "three-branched" classification of the Tibetic languages, the Lhasa dialect belongs to the Central Tibetan branch (the other two being Khams Tibetan and Amdo Tibetan). In terms of mutual intelligibility, speakers of Khams Tibetan are able to communicate at a basic level with Lhasa Tibetan, while Amdo speakers cannot. Both Lhasa Tibetan and Khams Tibetan evolved to become tonal and do not preserve the word-initial consonant clusters, which makes them very far from Classical Tibetan, especially when compared to the more conservative Amdo Tibetan. Registers Like many languages, Lhasa Tibetan has a variety of language registers: * ( Wylie: , literally " demotic language"): the vernacular speech. * ( Wylie: , "honorifics or deference, courtesy"): the ...

Lithium Chloride
Lithium chloride is a chemical compound with the formula Li Cl. The salt is a typical ionic compound (with certain covalent characteristics), although the small size of the Li+ ion gives rise to properties not seen for other alkali metal chlorides, such as extraordinary solubility in polar solvents (83.05 g/100 mL of water at 20 °C) and its hygroscopic properties. Chemical properties The salt forms crystalline hydrates, unlike the other alkali metal chlorides. Mono-, tri-, and pentahydrates are known. The anhydrous salt can be regenerated by heating the hydrates. LiCl also absorbs up to four equivalents of ammonia/mol. As with any other ionic chloride, solutions of lithium chloride can serve as a source of chloride ion, e.g., forming a precipitate upon treatment with silver nitrate: : LiCl + AgNO3 → AgCl + LiNO3 Preparation Lithium chloride is produced by treatment of lithium carbonate with hydrochloric acid. Anhydrous LiCl is prepared from the hydrate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renminbi
The renminbi ( ; currency symbol, symbol: Yen and yuan sign, ¥; ISO 4217, ISO code: CNY; abbreviation: RMB), also known as the Chinese yuan, is the official currency of the China, People's Republic of China. The renminbi is issued by the People's Bank of China, the Central bank, monetary authority of China. It is the world's Template:Most traded currencies, fifth-most-traded currency as of April 2022. The Yuan (currency), yuan () is the basic unit of the renminbi. One yuan is divided into 10 Jiao (currency), jiao (), and the jiao is further subdivided into 10 Fen (currency), fen (). The word ''yuan'' is widely used to refer to the Chinese currency generally, especially in international contexts. Valuation Until 2005, the value of the renminbi was Fixed exchange-rate system, pegged to the United States dollar, US dollar.

Tibet Mineral Development
Tibet Mineral Development Company Limited, known as Tibet Mining ( zh, 西藏矿业, ), is a partly state-owned enterprise engaged in the exploration, mining, processing, and sales of non-ferrous mineral resources in the Tibet Autonomous Region. The company focuses on chromium, copper, and increasingly lithium resources. It operates under the control of China Baowu Iron & Steel Group, one of the largest state-owned steel companies in China. History The company originated with the creation of the Dongfeng Mine ( zh, 东风矿) in 1967, a state-owned operation established under the direction of the central government. In 1984, with approval from the Ministry of Metallurgy and the People's Government of the Tibet Autonomous Region, the Dongfeng Mine team was relocated to Lobusha Township, Qusum County in Shannan, Tibet, where they initiated mining operations at the Lobusha Mine.

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for Chronological dating, determining the age of an object containing organic material by using the properties of carbon-14, radiocarbon, a radioactive Isotopes of carbon, isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Atmosphere of Earth, Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alkali Metal
The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K),The symbols Na and K for sodium and potassium are derived from their Latin names, ''natrium'' and ''kalium''; these are still the origins of the names for the elements in some languages, such as German and Russian. rubidium (Rb), caesium (Cs), and francium (Fr). Together with hydrogen they constitute Group (periodic table)#Group names, group 1, which lies in the s-block of the periodic table. All alkali metals have their outermost electron in an s-orbital: this shared electron configuration results in their having very similar characteristic properties. Indeed, the alkali metals provide the best example of periodic trends, group trends in properties in the periodic table, with elements exhibiting well-characterised Homologous series, homologous behaviour. This family of elements is also known as the lithium family after its leading element. The alkali metals are all shiny, hardness, sof ...

Mirabilite
Mirabilite, also known as Glauber's salt, is a hydrous sodium sulfate mineral with the chemical formula Na2SO4·10H2O. It is a vitreous, colorless to white monoclinic mineral that forms as an evaporite from sodium sulfate-bearing brines. It is found around saline springs and along saline playa lakes. Associated minerals include gypsum, halite, thenardite, trona, glauberite, and epsomite. Mirabilite is unstable and quickly dehydrates in dry air, the prismatic crystals turning into a white powder, thenardite (Na2SO4). In turn, thenardite can also absorb water and converts to mirabilite. Mirabilite is used as a purgative and anti-inflammatory remedy in the Traditional Chinese medicine; in Mandarin, it is called máng xiāo 硭硝. The name 'mirabilite' is based on the phrase ''"Sal mirabilis"'' (Latin for "wonderful salt") used by Johann Rudolph Glauber when he inadvertently synthesized mirabilite. Mirabilite is found in several areas within the Mammoth Cave System, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
