Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

Sejong The Great Of Joseon
Sejong of Joseon (15 May 1397 – 8 April 1450), personal name Yi Do (Korean language, Korean: 이도; Hanja: 李祹), widely known as Sejong the Great (Korean language, Korean: 세종대왕; Hanja: 世宗大王), was the fourth ruler of the Joseon, Joseon dynasty of Korea. Initially titled Grand Prince Chungnyeong (Korean language, Korean: 충녕대군; Hanja: 忠寧大君), he was born as the third son of Taejong of Joseon, King Taejong and Queen Wongyeong. In 1418, he was designated as Crown prince, heir after his eldest brother, Grand Prince Yangnyeong, Crown Prince Yi Je, was stripped of his status. Today, King Sejong is regarded as one of the greatest leaders in Korean history. Despite ascending to the throne after his father's voluntary abdication in 1418, Sejong was a mere figurehead while Taejong continued to hold the real power and govern the country up till his death in 1422. Sejong was the sole monarch for the next 28 years, although after 1439 he became increasi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Sericulture
Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, ''Bombyx mori'' (the caterpillar of the domestic silkmoth) is the most widely used and intensively studied silkworm. Silk was believed to have first been produced in China as early as the Neolithic Period. Sericulture has become an important cottage industry in countries such as Brazil, China, France, India, Italy, Japan, Korea, and Russia. Today, China and India are the two main producers, with more than 60% of the world's annual production. History According to Confucian text, the discovery of silk production dates to about 2700 BC, although archaeological records point to silk cultivation as early as the Yangshao period (5000–3000 BC). In 1977, a piece of ceramic created 5400–5500 years ago and designed to look like a silkworm was discovered in Nancun, Hebei, providing the earliest known evidence of sericulture. Also, by careful a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proso Millet
''Panicum miliaceum'' is a grain crop with many common names, including proso millet, broomcorn millet, common millet, hog millet, Kashfi millet, red millet, and white millet. Archaeobotanical evidence suggests millet was first domesticated about 10,000 BP in Northern China. The crop is extensively cultivated in China, India, Nepal, Russia, Ukraine, Belarus, the Middle East, Turkey, Romania, and the United States, where about half a million acres are grown each year. The crop is notable both for its extremely short lifecycle, with some varieties producing grain only 60 days after planting, and its low water requirements, producing grain more efficiently per unit of moisture than any other grain species tested. The name "proso millet" comes from the pan-Slavic general and generic name for millet ( sh-Latn-Cyrl, separator=/, proso, просо, cs, proso, pl, proso, russian: просо). Proso millet is a relative of foxtail millet, pearl millet, maize, and sorghum within the gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amur Leopard
The Amur leopard (''Panthera pardus orientalis'') is a leopard subspecies native to the Primorye region of southeastern Russia and northern China. It is listed as Critically Endangered on the IUCN Red List, as in 2007, only 19–26 wild leopards were estimated to survive in southeastern Russia and northeastern China. It is considered one of the rarest cats on Earth. , fewer than 60 individuals were estimated to survive in Russia and China. Camera-trapping surveys conducted between 2014 and 2015 revealed 92 individuals in an large transboundary area along the Russian-Chinese border. In 2019, it was reported that the population was about 90 leopards. In 2021, it was reported the population was about 110 individuals. Results of genetic research indicate that the Amur leopard is genetically close to leopards in northern China and Korea, suggesting that the leopard population in this region became fragmented in the early 20th century. The North Chinese leopard was formerly recogn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
