Miscanti
Cerro Miscanti (also known as Ipira) is a mountain located in the Antofagasta Region of Chile, immediately south of Chiliques and north of Miñiques. It towers over Laguna Miscanti. Rock samples from Cerro Miscanti are of andesitic composition, but andesite-containing dacites have also been found. The edifice covers an area of and bears traces of a westward collapse, which exposed the internal sector of the volcano. A new volcano grew inside the collapse scar. Miscanti may be either extinct or may have erupted in the Pleistocene-Holocene. Renewed eruptions are likely to consist of lava flows, which could impact the northern shores of Laguna Miscanti. An Inka sanctuary has been reported from Cerro Miscanti.

Laguna Miscanti
Miscanti Lake (Spanish: ''Laguna Miscanti'') is a brackish water lake located in the altiplano of the Antofagasta Region in northern Chile. Cerro Miñiques volcano and Cerro Miscanti tower over this lake. This large heart-shaped lake has a deep blue colour and developed in a basin formed by a fault. South of Miscanti lies Laguna Miñiques, another lake which is separated from Miscanti by a lava flow that was emplaced there during the Pleistocene. The lake is part of one of the seven sectors of Los Flamencos National Reserve. A number of birds and mammals live at the lake, which is a major tourist destination. Geography Laguna Miscanti lies in the Central Andes of Chile, east-southeast of the Salar de Atacama. Administratively, it is part of the Antofagasta Region. The closest town is Socaire, away from the lake. A road departing from the Paso Sico international road goes to Miscanti, which is accessible by an unpaved road and numerous footpaths. In 2002, there were 5,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cordón De Puntas Negras
Cordón de Puntas Negras is a volcanic chain located east of the Salar de Atacama in Chile's Antofagasta Region. Cordón de Puntas Negras is constructed along the major Calama–Olacapato–El Toro fault and is long. The long volcanic chain intersects with the long Cordón Chalviri volcanic chain. Both chains cover a surface area of and contain cones, vents, lava domes, lava flows and maars, including a lava dome and silicic flow with a surface area of . Puntas Negras specifically covers an area of and is the highest summit in the chain and features a wide crater and a long pyroclastic flow. Puntas Negras runs from the Chiliques volcano on the north to volcán Puntas Negras () almost to the SE. The Puntas Negras Volcano forms the common endpoint of two chains of volcanoes in a V-shaped configuration. The southern leg of the V is called "Cordón Chalviri" whose other extreme is the Cerro Tuyajto, SW of Puntas Negras and at the same distance SE of the Miñiques volcano. S ...

Miñiques
Miñiques is a massive volcanic complex containing a large number of craters, lava domes and flows, located in the Antofagasta Region of Chile. Located south of Volcán Chiliques and west of Cordón Puntas Negras, it is part of a frequently visited attraction conformed by the high plain lagoons Laguna Miscanti, Laguna Miñiques and the Cerro Miscanti volcano. Mountain Miñiques consists of four overlapping volcanoes formed by lava domes and stratovolcanoes. It has two summits, a lower northern summit which reaches elevation and a higher southern one which is high. The mountain features two crater lakes, one at and the other at elevation on the southeastern and western side of the northern summit, respectively. A set of well developed moraines exists on the southern flank and may reflect glaciers advancing either from the summit area or a plateau at elevation; overall however glaciation on Miñiques was of limited extent and the terrain of Miñiques today is do ...

Chiliques
Chiliques is a stratovolcano located in the Antofagasta Region of Chile. Chiliques is capped off by a wide summit crater, which contains two crater lakes. One of these lakes is found in the northern part and the other east-southeastern part. The volcano is formed by rocks ranging from andesite to dacite; the andesites of the main stratocone building phase contain pyroxene. Together with Tumisa, Leija and Cordón de Puntas Negras it forms a northwest-trending volcano alignment. The first part of Chiliques to form was a block lava field, which still crops out northeast of the main volcano to a distance of . Lava flows with lengths of up to then constructed the stratovolcano proper and were later buried by shorter (up to ) lava flows that cover a surface of around the summit crater. The Cerro Overo maar northeast of Chiliques is occasionally considered the last phase of Chiliques's activity, and the two have erupted rocks with similar chemical composition but later resear ...

Caichinque
Caichinque is a volcanic complex lying between Salar de Talar and ''Salar de Capur'', in the high Andean plateau of the Antofagasta Region, in Chile. It is located southwest of the Salar de Atacama, directly S of Cerro Miñiques and SE of Cordón Puntas Negras forming part of the main branch of the Andean volcanic chain in this area. Route CH-23 is an approach road to the volcano area and could be impacted by eruptions. The volcano has erupted rocks with composition ranging from basalt to dacite. It grew atop a rhyodacitic ignimbrite.

Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after ...

Inca Empire
The Inca Empire (also known as the Incan Empire and the Inka Empire), called ''Tawantinsuyu'' by its subjects, ( Quechua for the "Realm of the Four Parts", "four parts together" ) was the largest empire in pre-Columbian America. The administrative, political and military center of the empire was in the city of Cusco. The Inca civilization arose from the Peruvian highlands sometime in the early 13th century. The Spanish began the conquest of the Inca Empire in 1532 and by 1572, the last Inca state was fully conquered. From 1438 to 1533, the Incas incorporated a large portion of western South America, centered on the Andean Mountains, using conquest and peaceful assimilation, among other methods. At its largest, the empire joined modern-day Peru, what are now western Ecuador, western and south central Bolivia, northwest Argentina, the southwesternmost tip of Colombia and a large portion of modern-day Chile, and into a state comparable to the historical empires of ...

Mountains Of Chile
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Volcanoes Of Antofagasta Region
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide p ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
