Baskunchak
Lake Baskunchak (russian: Баскунчак; kk, Басқұншақ, translit=Basqunshaq) is a salt lake of 115 km² in Astrakhan Oblast, Russia, located at , about 270 km north of the Caspian Sea, and 53 km east of the Volga. Since 1997, the area is protected as part of the Bogdinsko-Baskunchakski Nature Reserve. The surface elevation of the lake is 21 m below sea level. It is fed by a river that draws from an area of 11,000 km². The salinity of the lake is about 300 g/L. Since the 8th century, its salt was mined and traded along the Silk Road. Nowadays, the lake's salt of distinct purity (99.8% NaCl) covers 80% of Russia's salt production. Depending on demand, 1.5 million to 5 million tons of salt are mined per year. To the south of the lake, Mount Bolshoye Bogdo rises to 150 m above sea level, forming the highest elevation in the Caspian Depression. The hill is pushed up about 1 mm per year by a salt dome. Sinkholes, and Karst caves of up to 1.5&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogdinsko-Baskunchakski Nature Reserve
Bogdinsko-Baskunchakski Nature Reserve (russian: Богдинско-Баскунчакский) (also Bogdinsko-Baskunchaksky) is a Russian ' zapovednik' (strict nature reserve) in a semi-arid area around two notable features: Lake Baskunchak, Russia's largest undrained salt lake, and Big Bogdo Mountain, the highest point (at 147 meters) in the Caspian Depression and home to the "singing rocks". It is about halfway between Volgograd and Astrakhan, placing it about 200 km north of the Volga River Delta, where the river enters the Caspian Sea from the northwest. About 20 km east of the lake is the border with Kazakhstan. Baskunchak has been a source of salt to Russia for centuries. The reserve is an important site on the bird migration route between northern Siberia and wintering regions. The reserve is situated in the Akhtubinsky District of Astrakhan Oblast. Topography The reserve lies in the trough of the Caspian Depression, just east of the Volga's present m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caspian Depression
The Caspian Depression ( kk, Каспий маңы ойпаты, ''Kaspıı mańy oıpaty''; rus, Прикаспи́йская ни́зменность, p=prʲɪkɐˈspʲijskəjə ˈnʲizmʲɪnnəsʲtʲ, Caspian Lowland) or Pricaspian/Peri-Caspian Depression/Lowland is a low-lying flatland region encompassing the northern part of the Caspian Sea, the largest enclosed body of water on Earth. It is the larger northern part of the wider Aral-Caspian Depression around the Aral and Caspian Seas. The level of the Caspian sea is below sea level, however several areas in the depression are even lower, and among them Karagiye near Aktau is the lowest at . Geography The depression lies at the southern end of the Ryn Desert, and is in both Kazakhstan and Russia. Most of the Russian Republic of Kalmykia lies in the Caspian Depression. The Volga River and the Ural River flow into the Caspian Sea through this region. The deltas of the Ural and Volga Rivers are extensive wetlands. Th ...

Salt Lake (geography)
A salt lake or saline lake is a landlocked body of water that has a concentration of salts (typically sodium chloride) and other dissolved minerals significantly higher than most lakes (often defined as at least three grams of salt per litre). In some cases, salt lakes have a higher concentration of salt than sea water; such lakes can also be termed hypersaline lakes, and may also be pink lakes on account of their colour. An alkalic salt lake that has a high content of carbonate is sometimes termed a soda lake. One saline lake classification differentiates between: *subsaline: 0.5–3 ‰ (0.05-0.3%) *hyposaline: 3–20‰ (0.3-2%) *mesosaline: 20–50‰ (2-5%) *hypersaline: greater than 50‰ (5%) Properties Salt lakes form when the water flowing into the lake, containing salt or minerals, cannot leave because the lake is endorheic (terminal). The water then evaporates, leaving behind any dissolved salts and thus increasing its salinity, making a salt lake an excellent pl ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Blac ...

Lakes Of Astrakhan Oblast
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Elton
Lake Elton (russian: Эльтон; kk, Эльтон, translit=Elton) is a salt lake in Volgograd Oblast, Russia, near the border with Kazakhstan. It has an area of 152 km² and is about 0.1 m deep (in spring 0.7 to 0.8 m). Its surface is 18 m below sea level. The lake’s name originates from the Kazakh language: “Altyn-Nor” (Golden Bottom). Long ago local nomads used the lake’s mineral-rich mud for skin and respiratory treatments. For centuries, Lake Elton was a favorite location for Russian rulers and nobles. One can still see remnants of Empress Yekaterina II’s “bath” there. It is the largest mineral lake in Europe and one of the most mineralized in the world. The lake is filled with saturated salt solution. Mineralization is 200-500 g/L. Salt, extracted from the lake since the early 18th century, is used for the production of magnesium chloride. The water contains '' Dunaliella salina'' algae that give a reddish shade to the lake. At the bottom of the lake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dead Sea
The Dead Sea ( he, יַם הַמֶּלַח, ''Yam hamMelaḥ''; ar, اَلْبَحْرُ الْمَيْتُ, ''Āl-Baḥrū l-Maytū''), also known by other names, is a salt lake bordered by Jordan to the east and Israel and the West Bank to the west. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River. As of 2019, the lake's surface is below sea level, making its shores the lowest land-based elevation on Earth. It is deep, the deepest hypersaline lake in the world. With a salinity of 342 g/kg, or 34.2% (in 2011), it is one of the world's saltiest bodies of water – 9.6 times as salty as the ocean – and has a density of 1.24 kg/litre, which makes swimming similar to floating. This salinity makes for a harsh environment in which plants and animals cannot flourish, hence its name. The Dead Sea's main, northern basin is long and wide at its widest point. The Dead Sea has attracted visitors from around the Mediterranean Basin for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medicinal Clay
The use of medicinal clay in folk medicine goes back to prehistoric times. Indigenous peoples around the world still use clay widely, which is related to geophagy. The first recorded use of medicinal clay goes back to ancient Mesopotamia. A wide variety of clays are used for medicinal purposes—primarily for external applications, such as the clay baths in health spas (mud therapy). Among the clays most commonly used are kaolin and the smectite clays such as bentonite, montmorillonite, and Fuller's earth. History Ancient Egypt and Mesopotamia The first recorded use of medicinal clay is on Mesopotamian clay tablets around 2500 B.C. Also, ancient Egyptians used clay. The Pharaohs’ physicians used the material as anti-inflammatory agents and antiseptics. It was used as a preservative for making mummies and is also reported that Cleopatra used clays to preserve her complexion. The Ebers Papyrus of about 1550 BC (but containing the tradition going back many centuries earlier) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kalmyk People
The Kalmyks ( Kalmyk: Хальмгуд, ''Xaľmgud'', Mongolian: Халимагууд, ''Halimaguud''; russian: Калмыки, translit=Kalmyki, archaically anglicised as ''Calmucks'') are a Mongolic ethnic group living mainly in Russia, whose ancestors migrated from Dzungaria. They created the Kalmyk Khanate from 1635 to 1779 in Russia's North Caucasus territory. Today they form a majority in Kalmykia, located in the Kalmyk Steppe, on the western shore of the Caspian Sea. They are the only traditionally Buddhist people whose homeland is located within Europe. Through emigration, small Kalmyk communities have been established in the United States, France, Germany, and the Czech Republic. Origins and history Early history of the Oirats The Kalmyk are a branch of the Oirat Mongols, whose ancient grazing-lands spanned present-day parts of Kazakhstan, Russia, Mongolia and China. After the fall of the Mongol Yuan dynasty of China in 1368, the Oirats emerged as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
