Central Valley Of Chile
The Central Valley (), Intermediate Depression, or Longitudinal Valley is the depression between the Chilean Coastal Range and the Andes Mountains. The Chilean Central Valley extends from the border with Peru to Puerto Montt in southern Chile, with a notable interruption at Norte Chico (27°20'–33°00' S). South of Puerto Montt the valley has a continuation as a series of marine basins up to the isthmus of Ofqui. Some of Chile's most populous cities lie within the valley including Santiago, Temuco, Rancagua, Talca and Chillán. Northern section (18°30'–27°20' S) In northernmost Chile the central valley is made up of the Pampitas, a series of small flats dissected by deep valleys.Börger, p. 40. Immediately south of the Pampitas, in Tarapacá Region and northern of Antofagasta Region, the Central Valley is known as Pampa del Tamarugal.Börger, p. 41.Brüggen, p. 6. Contrary to the Pampitas valleys descending from the Andes do not incise the plains but merge into the surf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chilean Coast Range
The Chilean Coastal Range () is a mountain range that runs from north to south along the Pacific Ocean, Pacific coast of South America parallel to the Andes, Andean Mountains, extending from Morro de Arica in the north to Taitao Peninsula, where it ends at the Chile triple junction, in the south. The range has a strong influence on the climate of Chile since it produces a rain shadow to the east. Because of this the vegetation growing on the seaward slopes is much more exuberant than in the interior. Compared to the coastal lowlands and the Intermediate Depression, it is sparsely populated with land use varying from protected areas of Chile, protected areas to grazing and silviculture. The range is present in all Chilean regions, except for Coquimbo Region and Magallanes Region. Geography Like the Andes, the coastal range becomes progressively lower with increasing latitude. The range begins at Morro de Arica in the north and reaches its highest point, of above sea level, in Sier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarapacá Region
The Tarapacá Region (, ) is one of Chile's 16 first-order Administrative divisions of Chile, administrative divisions. It comprises two provinces, Iquique Province, Iquique and Tamarugal Province, Tamarugal. It borders the Chilean Arica y Parinacota Region to the north, Bolivia's Oruro Department and Potosí Department on the east, Chile's Antofagasta Region to the south and the Pacific Ocean to the west. The port city of Iquique is the region's capital. Much of the region was once the Tarapacá Province (Peru), Tarapacá Province of Peru, which was annexed by Chile under the 1883 Treaty of Ancón at the close of the War of the Pacific. The region was important economically as a site of intense Chile saltpeter, saltpeter mining, before synthetic nitrate manufacturing became possible. A number of abandoned mining towns can still be found in the region. The present day Tarapacá Region was created in 2007 by subdividing the former Tarapacá Region under Law No. 20,175, which w ...

Nolana Leptophylla
''Nolana'' (Peruvian bell flower) is a genus of hard annual or perennial plants in the nightshade family. The genus is mostly native to Chile and Peru. Species in this genus, especially '' N. paradoxa'', serve as a model system for studies on flower color. Classification There are a number of synonyms for ''Nolana'': ''Alibrexia'', ''Alona'', ''Aplocarya'', ''Bargemontia'', ''Dolia'', ''Gubleria'', ''Leloutrea'', ''Neudorfia'', ''Osteocarpus'', ''Periloba'', ''Rayera'', ''Sorema'', ''Teganium'', ''Tula'', ''Velpeaulia'', ''Walkeria'', and ''Zwingera''. ''Nolana'' is the only genus in the Solanaceae which has a fruit composed of mericarps, although its flower and other vegetative morphology is similar to other plants in this family. It seems to be most closely related to ''Lycium''. Species ''Plants of the World Online Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew.

Atacama Desert
The Atacama Desert () is a desert plateau located on the Pacific Ocean, Pacific coast of South America, in the north of Chile. Stretching over a strip of land west of the Andes Mountains, it covers an area of , which increases to if the barren lower slopes of the Andes are included. The Atacama Desert is the driest nonpolar desert in the world, and the second driest overall, behind some specific spots within the McMurdo Dry Valleys. It is the only Desert climate, true desert to receive less precipitation than polar deserts, and the largest fog desert in the world. The area has been used as an experimentation site for Mars expedition simulations due to its similarities to the Martian environment. The constant Inversion (meteorology), temperature inversion caused by the cool north-flowing Humboldt Current, Humboldt ocean current and the strong South Pacific High, Pacific anticyclone contribute to the extreme aridity of the desert. The most arid region of the Atacama Desert is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault (geology)
In geology, a fault is a Fracture (geology), planar fracture or discontinuity in a volume of Rock (geology), rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust (geology), crust result from the action of Plate tectonics, plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction, subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the Plane (geometry), plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone ...

Chañaral
Chañaral is a small coastal city and commune in the Atacama Region, Chile and capital of the Chañaral Province. The ocean is contaminated by the copper mining activity in the area. Just north of the city lies Pan de Azúcar National Park. It is the central town of a mining district dominated by medium-scale mining, including the nearby El Carmen mine which is considered the basis for the medium-scale iron mining in Chile. History In 1824, Diego de Almeyda discovered significant copper deposits near Chañaral, and copper mining began in the area. The town was founded in October 26, 1833 as ''Chañaral de las Ánimas'' ("Chañar field of the Souls"). Demographics According to the 2002 census by the National Statistics Institute (''INE'') the commune of Chañaral spans an area of and had 13,543 inhabitants (6,968 men and 6,575 women).

Taltal
Taltal is a Chilean commune and city in Antofagasta Province, Antofagasta Region. According to the 2012 census, the commune has a population of 11,132 and has an area of . The commune is home to Paranal Observatory and includes the northern portion of Pan de Azúcar National Park. The commune of Taltal hosts multiple copper mines including Franke, Altamira and Las Luces; all operated and owned by Grupo Minero Las Cenizas. Etymology It has been claimed the etymological origin of the name is the Mapuche word ''Thalthal'', which means “night bird.” This would make it one of the northernmost Mapuche toponyms in Chile. History The history of Taltal begins with the opening of the copper mine "El Cobre" by José Antonio Moreno in 1850 about 20 kilometers north of Taltal. This brought miners and prospectors to the area. In 1855 Moreno expanded his operations to include Taltal. The discovery of copper in 1858 on nearby Mount Cachiyuyal increased pressure on the port, which h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cordillera Domeyko
The Cordillera Domeyko is a mountain range of the Andes located in northern Chile, west of Salar de Atacama. It runs north-south for approximately 600 km, parallel to the main chain. The mountain range marks the eastern border of the flat parts of Atacama Desert. The western border of Cordillera Domeyko is characterized by a inland cliffs and a sharp topographic transition known as El Bordo Escarpment. El Bordo Escarpment contain the main rock outcrop An outcrop or rocky outcrop is a visible exposure of bedrock or ancient superficial deposits on the surface of the Earth and other terrestrial planets. Features Outcrops do not cover the majority of the Earth's land surface because in most p ...s of the Purilactis Group, which make up much of the mountain range.

Loa River
The Loa River (Spanish: Río Loa) is a U-shaped river in Chile's northern Antofagasta Region. At long, it is the country's longest river and the main watercourse in the Atacama Desert. Course The Loa's sources are located on Andean mountain slopes at the foot of Miño Volcano. The upper Loa basin is flanked on the west by a ridge with elevations that reach above , whereas to the east lies a volcanic chain (including Aucanquilcha, Palpana and San Pedro), which separates it from endorheic basins as that of Salar de Ascotán. The river flows south on an elevated plateau from to altitude, part of the Alto Loa National Reserve, for about , to the oasis of Chiu Chiu. The upper courses of the river are at a considerable elevation above sea level and receive water from the Andes, mainly of two major tributaries: San Pedro de Inacaliri River and Salado River. The former joins the Loa near Conchi dam and reservoir and the latter about south of Chiu Chiu. The water of its uppe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
