Mulpún
Mulpún is a coal mine and locality in Los Ríos Region, Chile. Mulpún lies in the commune of Máfil a few kilometers to the west of the Chile Route 5 and north of the Calle-Calle and San Pedro River. History The mine was exploited during parts of the 20th century when its coal powered the electric grid of the city of Valdivia. The mine has been owned by ''Compañía Carbonífera San Pedro de Catamutún'' since 1987. In 1992 and 1993 a gravimetric exploration campaign was conducted. The mine was planned to re-open in 1997. As the Catamutún mines closed in the late 1990s some miners were transferred to Mulpún, but mining in Mulpún ended in 2001 after an explosion accident. An underground coal gasification project in the closed Mulpún mine was made public in 2009 but was put on hold in 2013. The project was a joint-venture between Antofagasta Minerals and Carbon Energy until 2013. Geology At Mulpún there is one sub-horizontal coal layer whose thickness vary from 9 to 11 m ...

Estratos De Pupunahue
Estratos de Pupunahue is the name given to the sedimentary strata of Oligocene-Miocene age that crop out in Pupunahue and Mulpún near Valdivia, Chile. Outside this locality Estratos de Pupunahue extends below the surface over a larger area. The thickness of the strata varies from a few meters to 530 meters. The strata were initially described by Henning Illies. The strata are made up of conglomerate, sandstone and mudstone (Chilean Spanish: ''fangolita''). The clast of the conglomerates are made up of metamorphic rock and the disposition of the conglomerates varies from clast-supported to matrix-supported. The sandstone and mudstone contain layers of lignite coal that exceed 30 cm in thickness. Coal layers found in the Estratos de Pupunahue have been exploited in the mines of Catamutún, Pupunahue and Mulpún ("Mulpun Beds"). The strata are very similar to the Cheuquemó Formation found further north, with the sole difference that the fossil assemblage in both seems to ind ...

La Unión, Chile
La Unión is a city and commune of the Ranco Province in the Los Ríos Region in Chile. It is situated approximately 40 km north of Osorno and 80 km southeast of Valdivia. Covering an area of 2,136.7 km2, it has a population of 36,447, of which 25,615 are considered part of the urban population, according to the 2012 census. The commune derived its name from the confluence of the Llollelhue and Radimadi rivers. La Unión was founded in 1821 during the government of Bernardo O'Higgins, to secure sovereignty over the Central Valley south of Valdivia. It is a major centre for milk production; COLUN is the main milk and dairy product producer in the zone. The commune is covered in forest to the west of the city and the east is dominated by agricultural landscapes spanning Los Llanos. Alerce Costero National Park lies in the western mountains. The city served until 2001 as a dormitory town for the coal mines of Catamutún. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cheuquemó Formation
Cheuquemó Formation ( es, Formación Cheuquemó) is a geological formation of sedimentary rock in south-central Chile. The sediments of the formation were deposited during the Late Oligocene and Early Miocene epochs. The formations lower sections are made up of conglomerate, then successions of sandstone, tuff and mudstone rich in organic material follows. The formation indicates that sedimentation occurred in an estuarine (paralic) and other non-marine (continental) environments. It contains fossils of the following genera: '' Mytilus'', '' Cardium'' and '' Turritella''. Stratigraphically it overlies the Bahía Mansa Metamorphic Complex and underlies the Miocene Santo Domingo Formation. Description The formation is very similar to the Pupunahue Beds found further north, with the sole difference that the fossil assemblage in both seem to indicate different ages. While Cheuquemó is possibly about 14 million years old (Miocene), the Pupunahue Beds are 35–25 million years old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Room And Pillar
Room and pillar or pillar and stall is a variant of breast stoping. It is a mining system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. To do this, "rooms" of ore are dug out while "pillars" of untouched material are left to support the roof overburden. Calculating the size, shape, and position of pillars is a complicated procedure, and is an area of active research. The technique is usually used for relatively flat-lying deposits, such as those that follow a particular stratum. Room and pillar mining can be advantageous because it reduces the risk of surface subsidence compared to other underground mining techniques. It is also advantageous because it can be mechanized, and is relatively simple. However, because significant portions of ore may have to be left behind, recovery and profits can be low. Room and pillar mining was one of the earliest methods used, although with significantly more man-power. The room ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Populated Places In Ranco Province
Population typically refers to the number of people in a single area, whether it be a city or town, region, country, continent, or the world. Governments typically quantify the size of the resident population within their jurisdiction using a census, a process of collecting, analysing, compiling, and publishing data regarding a population. Perspectives of various disciplines Social sciences In sociology and population geography, population refers to a group of human beings with some predefined criterion in common, such as location, race, ethnicity, nationality, or religion. Demography is a social science which entails the statistical study of populations. Ecology In ecology, a population is a group of organisms of the same species who inhabit the same particular geographical area and are capable of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with ind ...

Geography Of Los Ríos Region
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal Mines In Chile
Coal is a combustible black or brownish-black sedimentary rock, formed as stratum, rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Potato
The potato is a starchy food, a tuber of the plant ''Solanum tuberosum'' and is a root vegetable native to the Americas. The plant is a perennial in the nightshade family Solanaceae. Wild potato species can be found from the southern United States to southern Chile. The potato was originally believed to have been domesticated by Native Americans independently in multiple locations,University of Wisconsin-Madison, ''Finding rewrites the evolutionary history of the origin of potatoes'' (2005/ref> but later genetic studies traced a single origin, in the area of present-day southern Peru and extreme northwestern Bolivia. Potatoes were domesticated there approximately 7,000–10,000 years ago, from a species in the ''Solanum brevicaule'' complex. Lay summary: In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated. Potatoes were introduced to Europe from the Americas by the Spanish in the second half of the 16 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
