The Bolivian Andes produce principally tin although historically silver mining had a huge impact on the economy of 17th century Europe. Uyuni is a spectacularly giant salar and with a surface of >10,500 km 2 it is the largest salt pan of the Andes and on Earth (Risacher and Fritz, 1991; Kesler et al., 2012).This salt pan is located in the Altiplano at 3663 m a.s.l. The belt is subdivided into four main volcanic zones that are separated from each other by volcanic gaps. Locally, the relatives of the camel, the llama, and the alpaca continue to carry out important uses as pack animals, but this use has generally diminished in modern times. Cities and large towns are connected with asphalt-paved roads, while smaller towns are often connected by dirt roads, which may require a four-wheel-drive vehicle.[35]. c'est ce que nous voyons aujourd'hui depuis le mont Whistler - un vestige du plateau original qui a précédé les montagnes.

Because of the mountain slopes, terracing has been a common practice. The Southern and Central Andes and Patagonia. Although Andean Amerindian peoples crafted ceremonial jewelry of gold and other metals, the mineralizations of the Andes were first mined on a large scale after the Spanish arrival. In addition it makes cropping in the dry season (winter) possible and allows the cultivation of frost resistant vegetable crops like onion and carrot.[37]. Located on a high-altitude plateau at the edge of the Andes Mountains, the province is responsible for roughly 70 percent of the country's annual wine production. In which country are the Southern Alps located? In the central Andes (∼15°S to ∼27°S), the Central Andean Plateau (the Altiplano-Puna Plateau) is characterized by a high-elevation (>3 km), low-relief interior plateau, surrounded by the higher, more rugged Western and Eastern Cordilleras, the Sierra Pampeanas, and the Santa Barbara Ranges (Fig. Andes Mountains, South American mountain system that contains the highest peaks in the Western Hemisphere. From a geographical approach, the Andes are considered to have their western boundaries marked by the appearance of coastal lowlands and a less rugged topography. The high-altitude Polylepis forests and woodlands are found in the Andean areas of Colombia, Ecuador, Peru, Bolivia and Chile. Recherche - Définition. 2 Reviews.

Here the … The highest mountain outside Asia, Argentina's Mount Aconcagua, rises to an elevation of about 6,961 m (22,838 ft) above sea level. While some differences can be explained by which volcanic zone a volcano belongs to, there are significant differences inside volcanic zones and even between neighbouring volcanoes. La prairie Puna est un haut plateau qui se trouve dans la Cordillère des Andes. For example, the main crossover of the Andes between Argentina and Chile is still accomplished through the Paso Internacional Los Libertadores. In modern times, the largest cities in the Andes are Bogotá, with a population of about eight million, and Santiago, Medellín, and Cali. The Andes are the result of tectonic plate processes, caused by the subduction of oceanic crust beneath the South American Plate. The highest of them is Mount Aconcagua (22,831 feet [6,959 metres]) on the border of Argentina and Chile (see Researcher’s Note: Height of Mount Aconcagua). Only recently the ends of some highways that came rather close to one another from the east and the west have been connected. The world's highest volcanoes are in the Andes, including Ojos del Salado on the Chile-Argentina border, which rises to 6,893 m (22,615 ft). In unirrigated land, pasture is the most common type of land use. Yet another result of the dry climate are the salars of Atacama and Uyuni, the first one being the largest source of lithium today and the second the world's largest reserve of the element. There is a long history of mining in the Andes, from the Spanish silver mines in Potosí in the 16th century to the vast current porphyry copper deposits of Chuquicamata and Escondida in Chile and Toquepala in Peru. Opposite of the humid Andean slopes are the relatively dry Andean slopes in most of western Peru, Chile and Argentina. et des sommets. 15 (Quaternary Glaciation – Extent and Chronology, A Closer Look, Eds: Ehlers, J.; Gibbard, P.L. Some historians believe the name Andes comes from the Quechuan word anti (“east”); others suggest it is derived from the Quechuan anta (“copper”). [8] Further south lies the Maipo Orocline a more subtle Orocline between 30° S and 38°S with a seaward-concave break in trend at 33° S.[9] Near the southern tip of the Andes lies the Patagonian Orocline.[10]. The Altiplano plateau is the world's second-highest after the Tibetan plateau. The range is 7,000 km (4,350 mi) long, 200 to 700 km (124 to 435 mi) wide (widest between 18°S - 20°S latitude), and has an average height of about 4,000 m (13,123 ft). The Sierras de Córdoba, where the effects of the ancient Pampean orogeny can be observed, owe their modern uplift and relief to the Andean orogeny in the Tertiary. Along with several Interandean Valles, they are typically dominated by deciduous woodland, shrub and xeric vegetation, reaching the extreme in the slopes near the virtually lifeless Atacama Desert. Other cities in or near the Andes include Bariloche, Catamarca, Jujuy, Mendoza, Salta, San Juan, and Tucumán in Argentina; Calama and Rancagua in Chile; Cochabamba, Oruro, Potosí, Sucre, Sacaba, Tarija, and Yacuiba in Bolivia; Arequipa, Cajamarca, Cusco, Huancayo, Huánuco, Huaraz, Juliaca, and Puno in Peru; Ambato, Cuenca, Ibarra, Loja, Quito, Riobamba and Tulcán in Ecuador; Armenia, Cúcuta, Bucaramanga, Duitama, Ibagué, Ipiales, Manizales, Palmira, Pasto, Pereira, Popayán, Sogamoso, Tunja, and Villavicencio in Colombia; and Barquisimeto, La Grita, Mérida, San Cristóbal, Tovar, Trujillo, and Valera in Venezuela.

The largest glaciers, as e.g. It was sundown and the local vendors were no longer there. Parts of the La Paz conurbation, including the city of El Alto, extend up to 4,200 m (13,780 ft). Devastated by European diseases to which they had no immunity and civil wars, the Incas were defeated in 1532 by an alliance composed of tens of thousands of allies from nations they had subjugated (e.g. the Plomo glacier and the Horcones glaciers, do not even reach 10 km (6.2 mi) in length and have an only insignificant ice thickness. John Wiley & Sons Ltd, Chester-New York-Brisbane-Toronto-Singapore: 55–68. There is no universal agreement about the major north-south subdivisions of the Andes system. Bolivia has been a completely landlocked country ever since. Professor Emeritus of Geography, University of Wisconsin, Madison. To the east, the Andes range is bounded by several sedimentary basins, such as Orinoco, Amazon Basin, Madre de Dios and Gran Chaco, that separate the Andes from the ancient cratons in eastern South America.

The Andes can be divided into three sections: The Leeward Antilles islands Aruba, Bonaire, and Curaçao, which lie in the Caribbean Sea off the coast of Venezuela, were formerly thought to represent the submerged peaks of the extreme northern edge of the Andes range, but ongoing geological studies indicate that such a simplification does not do justice to the complex tectonic boundary between the South American and Caribbean plates. The term cordillera comes from the Spanish word cordel, meaning "rope",[2] and is used as a descriptive name for several contiguous sections of the Andes, as well as the entire Andean range, and the combined mountain chain along the western part of the North and South American continents. In the rainy season (summer), part of the rangeland is used for cropping (mainly potatoes, barley, broad beans and wheat). Along their length, the Andes are split into several ranges, separated by intermediate depressions. This article is about the mountain range in South America. Rainforests and tropical dry forests[27] used to encircle much of the northern Andes but are now greatly diminished, especially in the Chocó and inter-Andean valleys of Colombia. In: Chinese Translation Bulletin of Glaciology and Geocryology 5 (4): 1–17 (in Chinese language). [32] These forest-types, which includes the Yungas and parts of the Chocó, are very rich in flora and fauna, although few large mammals exist, exceptions being the threatened mountain tapir, spectacled bear and yellow-tailed woolly monkey. The Andean orogen has a series of bends or oroclines. The majority consensus is that it derives from the Quechua word anti, which means "east"[1] as in Antisuyu (Quechua for "east region"),[1] one of the four regions of the Inca Empire. The dry climate in the central western Andes has also led to the creation of extensive saltpeter deposits which were extensively mined until the invention of synthetic nitrates. [28], The vicuña and guanaco can be found living in the Altiplano, while the closely related domesticated llama and alpaca are widely kept by locals as pack animals and for their meat and wool. The Andes Mountains form a north–south axis of cultural influences. Kuhle, M. (1988): Subtropical Mountain- and Highland-Glaciation as Ice Age Triggers and the Waning of the Glacial Periods in the Pleistocene. In: Rachocki, A.H., Church, M. It was during the Cretaceous Period that the Andes began to take their present form, by the uplifting, faulting and folding of sedimentary and metamorphic rocks of the ancient cratons to the east. (1929): Zur Glazialgeologie der chilenischen Anden. The heathland plateau was awarded the status of Zone Naturelle d’Intérêt Écologique, Faunistique et Floristique [Natural Area of Importance for Ecology, Fauna and Flora] (ZNIEFF) in the eighties and a “Réserve Naturelle volontaire” (Voluntary Nature Reserve) then Regional Nature Reserve in 2009. Elsevier B.V., Amsterdam, pp. Définition ou synonyme. The potato holds a very important role as an internally consumed staple crop. Rundsch. The etymology of the word Andes has been debated.

Placez un Purian mûr sur le Plateau d’offrande de la Statue de régisseur. Best trails in Réserve naturelle du plateau des Landes. They began as sediments eroded from the Amazonia craton (or Brazilian shield)—the ancient granitic continental fragment that constitutes much of Brazil—and deposited between about 450 and 250 million years ago on the craton’s western flank. [34] The government sponsored the construction of aqueducts and roads in addition to preexisting installations. Potosí in present-day Bolivia and Cerro de Pasco in Peru was one of the principal mines of the Spanish Empire in the New World. For the purposes of this discussion, the system is divided into three broad categories. (eds.

Located on a high-altitude plateau at the edge of the Andes Mountains, the province is responsible for roughly 70 percent of the country's annual wine production. The Andes rose to fame for their mineral wealth during the Spanish conquest of South America. The Bolivian Orocline is a seaward concave bending in the coast of South America and the Andes Mountains at about 18° S.[5][6] At this point, the orientation of the Andes turns from Northwest in Peru to South in Chile and Argentina. The directional trend of both the cordilleras generally is north-south, but in several places the Cordillera Oriental bulges eastward to form either isolated peninsula-like ranges or such high intermontane plateau regions as the Altiplano (Spanish: “High Plateau”), occupying adjoining parts of Argentina, Chile, Bolivia, and Peru. Horton BK, Hampton BA, Waanders GL (2001) Paleogene synorogenic sedimentation in the Altiplano plateau and implications for initial mountain building in the central Andes. For decades, Chile claimed ownership of land on the eastern side of the Andes. 1; Allmendinger et al., 1997; Isacks, 1988; Strecker et al., 2007). It is the most extensive area of high plateau on Earth outside Tibet.The bulk of the Altiplano lies in Bolivia, but its northern parts lie in Peru, and its southern parts lie in Chile and Argentina. On the east side of this section of the Mendozina Andes, they flowed down to 2,060 m (6,759 ft) and on the west side to about 1,220 m (4,003 ft) above sea level. About 250 million years ago the crustal plates constituting the Earth’s landmass were joined together into the supercontinent Pangaea. See railroad maps of that region. It perhaps is more reasonable to ascribe it to the anta of the older Aymara language, which connotes copper colour generally. Université des Sciences et Technologies de Lille 1, Laboratoire Géosystèmes, 59655 Villeneuve d'ascq, France ... We analyze the spatiotemporal progression of basin isolation and filling at the eastern margin of the Puna Plateau of the Argentine Andes to determine if the topography predicted by such models is observed. Woodbine Parish and Joseph Barclay Pentland surveyed a large part of the Bolivian Andes from 1826 to 1827.
