Turpan Depression
The Turpan Depression or Turfan Depression, is a fault-bounded trough located around and south of the city-oasis of Turpan, in the Xinjiang Autonomous Region in far Western China, about southeast of the regional capital Ürümqi. It includes Lake Ayding, , the second or third lowest depression on Earth. By some measures, it is also the hottest and driest area in China during the summer. Geology and relief The Turpan Basin is a fault-bounded trough located in the eastern part of the Tian Shan. It covers an area of . The surrounding mountain ranges are: the central Tian Shan in the west, the Bogda Shan in the north-west, the Haerlike Shan in the north-west, and the Jueluotage Shan in the south. Beyond the surrounding mountain ranges lie the Junggar Basin in the north and the Tarim Basin in the south. Some geographers also use the term Turpan-Hami Basin, which is understood as including the Turpan Depression along with the Hami Depression (located to the east of the Turpan De ...

Hami City
Hami (Kumul) is a prefecture-level city in Eastern Xinjiang, China. It is well known as the home of sweet Hami melons. In early 2016, the former Hami county-level city was merged with Hami Prefecture to form the Hami prefecture-level city with the county-level city becoming Yizhou District. Since the Han dynasty, Hami has been known for its production of agricultural products and raw resources. Origins and names Cumuḍa (sometimes ''Cimuda'' or ''Cunuda'') is the oldest known endonym of Hami, when it was founded by a people known in Han Chinese sources as the '' Xiao Yuezhi'' ("Lesser Yuezhi"), during the 1st millennium BCE. The oldest attested Chinese names is "" (; by the time of the Han dynasty it was referred to in Chinese as "" () or "" (), in the Tang dynasty as , . By the 10th century CE, the city and its residents were known to the Han as "" ().

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 radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ayding Lake
Aydingkol ( Uyghur: , , ), Aydingkul (Mongol) or Ayding () is a lake in the Turpan Depression, Xinjiang Uyghur Autonomous Region, PR China. At 154 m below sea level, it is the lowest point in China. This lake is now totally dried, and very muddy and salty. History In ancient times, Ayding Lake was known as ''juéluòwǎn'' (觉洛浣). The Uyghur derived name ''Aydingköl'' means "moon lake", due to the lake having a layer of white salt along its edge, giving the appearance of a shining moon. Geography The lake is located in the south hinterland of the Turpan Depression, approximately 35 kilometres away from the city of Turpan. From east to west, the lake spans 40 kilometres; the north-south span is 8 kilometres; and the total area of the lake is 200 square kilometres. The lake was formed from the formation of an orogeny of the Himalayas 249 million years ago, and once held approximately 5 million square kilometres of inland sea, which at one time surged up and became vastly ex ...

Flaming Mountains
The Flaming Mountains () or Huoyan Mountains, are barren, eroded, red sandstone hills in the Tian Shan of Xinjiang. They lie near the northern rim of the Taklamakan Desert and east of the city of Turpan. Their striking gullies and trenches caused by erosion of the red sandstone bedrock give the mountains a flaming appearance at certain times of the day. The mountains are approximately long and wide, crossing the Turpan Depression from east to west. The average height of the Flaming Mountains is , with some peaks reaching over . The mountain climate is harsh and the extremely high summer temperatures make this the hottest spot in China, frequently reaching or higher. One of the largest thermometers in China is on display adjacent to the mountain, tracking the surrounding ground temperatures. It is a popular tourist spot. A number of important palaeontological remains have been found in the area, see e.g. Lianmuqin Formation and Subashi Formation. Silk route In ancient times, t ...

Cenozoic
The Cenozoic ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterised by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents. It is the latest of three geological eras since complex life evolved, preceded by the Mesozoic and Paleozoic. It started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia) in the southern hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Plate
The Eurasian Plate is a tectonic plate that includes most of the continent of Eurasia (a landmass consisting of the traditional continents of Europe and Asia), with the notable exceptions of the Indian subcontinent, the Arabian subcontinent and the area east of the Chersky Range in eastern Siberia. It also includes oceanic crust extending westward to the Mid-Atlantic Ridge and northward to the Gakkel Ridge. The eastern edge is a boundary with the North American Plate to the north and a boundary with the Philippine Sea Plate to the south and possibly with the Okhotsk Plate and the Amurian Plate. The southern edge is a boundary with the African Plate to the west, the Arabian Plate in the middle and the Indo-Australian Plate to the east. The western edge is a divergent boundary with the North American Plate forming the northernmost part of the Mid-Atlantic Ridge, which is straddled by Iceland. All volcanic eruptions in Iceland, such as the 1973 eruption of Eldfell, the 17 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Plate
The Indian Plate (or India Plate) is a minor tectonic plate straddling the equator in the Eastern Hemisphere. Originally a part of the ancient continent of Gondwana, the Indian Plate broke away from the other fragments of Gondwana , began moving north and carried Insular India with it. It was once fused with the adjacent Australian Plate to form a single Indo-Australian Plate, and recent studies suggest that India and Australia have been separate plates for at least 3 million years and likely longer. The Indian Plate includes most of modern South Asia (the Indian subcontinent) and a portion of the basin under the Indian Ocean, including parts of South China and western Indonesia, and extending up to but not including Ladakh, Kohistan and Balochistan. Plate movements Until roughly , the Indian Plate formed part of the supercontinent Gondwana together with modern Africa, Australia, Antarctica, and South America. Gondwana broke up as these continents drifted apart at di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angaran Craton
Siberia, also known as Angaraland (or simply Angara) and Angarida, is an ancient craton in the heart of Siberia. Today forming the Central Siberian Plateau, it was an independent continent before the Permian period. The Verkhoyansk Sea, a passive continental margin, was fringing the Siberian Craton to the east in what is now the East Siberian Lowland. Angaraland was named in the 1880s by Austrian geologist Eduard Suess who erroneously believed that in the Paleozoic there were two large continents in the Northern Hemisphere: "Atlantis", North America connected to Europe by a peninsula (=Greenland and Iceland); and "Angara-land", eastern Asia, named after the Angara River in Siberia. Precambrian history About 2.5 billion years ago ( Siderian), Siberia was part of a continent called Arctica, along with the Canadian Shield. Around 1.1 billion years ago (Stenian), Siberia became part of the supercontinent of Rodinia, a state of affairs which lasted until the Cryogenian about 750 m ...

East European Craton
The East European Craton (EEC) is the core of the Baltica proto- plate and consists of three crustal regions/segments: Fennoscandia to the northwest, Volgo-Uralia to the east, and Sarmatia to the south. Fennoscandia includes the Baltic Shield (also referred to as the Fennoscandian Shield) and has a diversified accretionary Archaean and early Proterozoic crust, while Sarmatia has an older Archaean crust. The Volgo-Uralia region has a thick sedimentary cover, however deep drillings have revealed mostly Archaean crust. There are two shields in the East European Craton: the Baltic/Fennoscandian shield and the Ukrainian shield. The Ukrainian Shield and the Voronezh Massif consists of 3.2-3.8 Ga Archaean crust in the southwest and east, and 2.3-2.1 Ga Early Proterozoic orogenic belts. The Ural Mountains are the eastern margin of the East European Craton and mark the Late Paleozoic orogenic collision of the East European Craton with the Siberian cratons.
