Paegam County
Paegam County is a ''kun'', or county, in Ryanggang province, North Korea. Geography The terrain is mountainous, as Paegam lies atop the Paektu Plateau, the site of North Korea's tallest mountains. The Hamgyŏng and Machŏllyŏng ranges pass through the county; the highest point is Kwesangbong. There are many streams; the chief of these is the Sodusu (서두수). There are also wetlands; some 91% of the county's area is forestland. Administrative divisions Paegam county is divided into 1 ''ŭp'' (town), 19 ''rodongjagu'' (workers' districts) and 4 ''ri'' (villages): Climate Due to its inland location, the county has a severely cold continental climate. Paegam also has the highest wind speeds of any district in North Korea. Economy Mining and logging are important local industries. Mineral resources in the county include magnesite, alunite, kaolinite, copper, dolomite, tungsten, lead, zinc, gold and peat. Agriculture also plays a role, although only 4% of the county's l ...

Korean State Railway
The Korean State Railway (), commonly called the State Rail () is the operating arm of the Ministry of Railways of North Korea and has its headquarters at P'yŏngyang. The current Minister of Railways is Chang Jun Song. History 1945–1953: Liberation, Partition, and the Korean War The railway lines of North Korea were originally built during the Japanese occupation of Korea by the Chosen Government Railway (''Sentetsu''), the South Manchuria Railway (''Mantetsu'') and various privately owned railway companies such as the Chosen Railway (''Chōtetsu''). At the end of the Pacific War, in the territory of today's North Korea Sentetsu owned of railway, of which was standard gauge, and was narrow gauge; in the same territory, privately owned railway companies owned of rail lines, of which was standard gauge and was narrow gauge. At the same time, in September 1945 in the future territory of the DPRK there were 678 locomotives (124 steam tank, 446 tender, 99 narrow ...

Paengmu Line
The Paengmu Line is a partially electrified narrow gauge line of the Korean State Railway running from Paeg'am on the Paektusan Ch'ŏngnyŏn Line to Musan on the Musan Line, in the Ryanggang and North Hamgyŏng provinces of North Korea.Kokubu, Hayato, 将軍様の鉄道 (Shōgun-sama no Tetsudō), The electrified section originally ran from Paeg'am Ch'ŏngnyŏn station to Yugok, whence the remaining to the terminus at Musan remained unelectrified. Since the closure of part of the line due to the construction of a reservoir, the line has been split into two disconnected sections, the electrified Paeg'am— Kulsong and the non-electrified Ch'ŏnsu—Musan sections. A new standard gauge section from Paeg'am to Taet'aek, roughly paralleling the narrow-gauge line, was built in 2013. History In 1927, the Government-General of Korea formulated a "12-Year Plan for Railways in Chosen", under which the railway network of the Korean Peninsula was to be greatly expanded. Alth ...

Paektusan Ch'ŏngnyŏn Line
The Paektusan Ch'ŏngnyŏn Line is an electrified standard-gauge secondary mainline of the Korean State Railway running from Kilju on the P'yŏngra Line to Hyesan on the Pukbunaeryuk Line; it connects to the narrow gauge Paengmu Line at Paeg'am Ch'ŏngnyŏn Station, and to the Samjiyŏn Line at Wiyŏn Ch'ŏngnyŏn Station.Kokubu, Hayato, 将軍様の鉄道 (Shōgun-sama no Tetsudō), Description This line traverses a very mountainous area; it has a ruling grade of 33‰ and a minimum curve radius of 250 metres. There are 74 bridges totalling and 24 tunnels with a total length of . The average distance between stations is . Service facilities on the line are at Hyesan for locomotives and at Wiyŏn and Paeg'am for rolling stock.The traffic and geography in North KoreaPaektusan Ch'ŏngnyŏn Line(in Korean) History In order to exploit the Paektusan region's abundant forest and mineral resources, the Yanggang Forest Development Railway planned construction of a line, dubbed ...

Kaolinite
Kaolinite ( ) is a clay mineral, with the chemical composition Al2 Si2 O5( OH)4. It is an important industrial mineral. It is a layered silicate mineral, with one tetrahedral sheet of silica () linked through oxygen atoms to one octahedral sheet of alumina () octahedra. Rocks that are rich in kaolinite are known as kaolin () or china clay. Kaolin is occasionally referred to by the antiquated term lithomarge, from the Ancient Greek ''litho-'' and Latin ''marga'', meaning 'stone of marl'. Presently the name lithomarge can refer to a compacted, massive form of kaolin. The name ''kaolin'' is derived from Gaoling (), a Chinese village near Jingdezhen in southeastern China's Jiangxi Province. The name entered English in 1727 from the French version of the word: , following François Xavier d'Entrecolles's reports on the making of Jingdezhen porcelain. Kaolinite has a low shrink–swell capacity and a low cation-exchange capacity (1–15 meq/100 g). It is a soft, earthy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alunite
Alunite is a hydroxylated aluminium potassium sulfate mineral, formula K Al3( S O4)2(O H)6. It was first observed in the 15th century at Tolfa, near Rome, where it was mined for the manufacture of alum. First called ''aluminilite'' by J.C. Delamétherie in 1797, this name was contracted by François Beudant three decades later to alunite. Alunite crystals morphologically are rhombohedron, rhombohedra with interfacial angles of 90° 50', causing them to resemble cubes. Crystal symmetry is trigonal. Minute glistening crystals have also been found loose in cavities in altered rhyolite. Alunite varies in color from white to yellow gray. The hardness on the Mohs scale is 4 and the specific gravity is between 2.6 and 2.8. It is insoluble in water or weak acids, but soluble in sulfuric acid. Sodium can substitute for potassium in the mineral, and when the sodium content is high, is called natroalunite. Alunite is an analog of jarosite, where aluminium replaces Fe3+. Alunite o ...

Magnesite
Magnesite is a mineral with the chemical formula (magnesium carbonate). Iron, manganese, cobalt, and nickel may occur as admixtures, but only in small amounts. Occurrence Magnesite occurs as veins in and an alteration product of ultramafic rocks, serpentinite and other magnesium rich rock types in both contact and regional metamorphic terrains. These magnesites are often cryptocrystalline and contain silica in the form of opal or chert. Magnesite is also present within the regolith above ultramafic rocks as a secondary carbonate within soil and subsoil, where it is deposited as a consequence of dissolution of magnesium-bearing minerals by carbon dioxide in groundwaters. Isotopic structure: clumped isotope The recent advancement in the field of stable isotope geochemistry is the study of isotopic structure of minerals and molecules. This requires study of molecules with high resolutions looking at bonding scenario (how heavy isotopes are bonded to each other)- leading to kno ...

Logging
Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. Logging is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products. Logging systems are also used to manage forests, reduce the risk of wildfires, and restore ecosystem functions, though their efficiency for these purposes has been challenged. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities. Illegal logging refers to the harvesting, transportation, purchase, or sale of timber in violation of laws. The harvesting procedure itself may be illegal, includin ...

Hamgyong Mountains
The Hamgyong Mountains ( ko, , , ''Hamgyeong Sanmaek''), officially known as the Gangbaekjeonggan and formerly known as the or , is a North Korean mountain range. It lies in the northeast quarter of the country, extending for about southwest and northeast parallel to the Sea of Japan (East Sea of Korea).. Its northern terminus is in the Tumen Valley. To its west are the Kaema Highlands. The southwestern end of the range, west of its turn northwards to meet the Tumen, is also known as the Pujollyong or (, , ''Bujeonryeong Sanmaek''). Overall, the Hamgyongs are the highest range of mountains on the peninsula.. The tallest mountain in the range is Kwanmo Peak (2,540 m), the second-highest after Paektu (China's "Changbai"). Other notable peaks include Du Peak (2,396 m), Gwesang Peak (2,333 m) and Mount Dury (2,303 m). In total, ten major peaks and 62 subsidiary peaks of the mountains in this range are 2,000 m or higher. __NOTOC__ See also * North & Sou ...
