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 rese ...

Cerro Overo
Cerro Overo is a volcanic crater in Chile. It lies at the foot of Chiliques volcano and close to Laguna Lejía, over ignimbrites of Pliocene age erupted by the La Pacana volcano. It is wide and deep and formed through combined explosive-effusive eruptions. The lavas are of lower crustal provenience and are among the least silicic in the region. Geography and geomorphology Cerro Overo is a wide volcanic crater, which is elongated in east-west direction. Its maximum depth is about . A thick layer of ejecta surrounds the maar and has a conspicuous black colour. Cerro Overo lies on the high Altos del Toro Blanco ridge at the northeastern foot of Chiliques volcano. Laguna Lejia, a local closed lake fed by spring (hydrology), springs, lies west-northwest of Cerro Overo. Geology Geologically, Cerro Overo is part of the Central Volcanic Zone (CVZ) of the Andes, which is represented by Lascar (volcano), Lascar and Chiliques volcanoes around Cerro Overo. The CVZ is one of four ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 domi ...

Tumisa
Tumisa (also known as ) is a Pleistocene stratovolcano in the Andes. Located east of the Salar de Atacama, it is part of the Central Volcanic Zone, which since the Miocene has been subject to extensive andesitic/dacitic effusive activity and ignimbrite eruptions. The basement on which Tumisa is built includes Paleozoic rocks and more recent volcanic products of the Lejia volcano and the Atana and Patao ignimbrites. Block flows, lava flows, lava domes and some ignimbrites of pumiceous composition form this composite volcano. More than six lava domes and two major cones are part of this system and surrounded by a pyroclastic apron, which covers a surface area of and is formed from many pyroclastic flows with a total volume of . The pyroclastic flows contain pumice and large blocks, some of which show signs of deformation when they were still hot. The lava domes and lavas are grouped in three units. Presumably, the activity of Tumisa started with explosive eruptions that generated the ... [...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. Se ...

Tambo (Incan Structure)
A tambo (Quechua: ''tampu'', "inn") was an Incan structure built for administrative and military purposes. Found along the extensive roads, tambos typically contained supplies, served as lodging for itinerant state personnel, and were depositories of quipu-based accounting records. Individuals from nearby communities within the Inca empire were conscripted to maintain and serve in the tambos, as part of the mit'a labor system. Tambos were spaced along Incan roads, generally about one day's travel apart. Characteristics and functions The Incas built many of their tambos when they began to upgrade their empire-wide road system during the reign of Thupa Inka Yupanki from 1471 to 1493. Scholars estimate there were 2,000 or more tambos.D’Altroy, Terence N. The Incas. Blackwell Publishing, 2003, pg. 238. Given this amount, the sheer variety of tambo size and function are hard to fully describe. At a minimum, tambos would contain housing, cooking facilities, and storage silos called ...

Drainage Divide
A drainage divide, water divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range. On flat terrain, especially where the ground is marshy, the divide may be difficult to discern. A triple divide is a point, often a summit, where three drainage basins meet. A ''valley floor divide'' is a low drainage divide that runs across a valley, sometimes created by deposition or stream capture. Major divides separating rivers that drain to different seas or oceans are continental divides. The term ''height of land'' is used in Canada and the United States to refer to a drainage divide. It is frequently used in border descriptions, which are set according to the "doctrine of natural boundaries". In glaciated areas it often refers to a low point on a divide where it is ...

Salar De Atacama
Salar de Atacama is the largest salt flat in Chile. It is located south of San Pedro de Atacama, is surrounded by mountains, and has no drainage outlets. In the east it is enclosed by the main chain of the Andes, while to the west lies a secondary mountain range of the Andes called Cordillera de Domeyko. Large volcanoes dominate the landscape, including the Licancabur, Acamarachi, Aguas Calientes and the Láscar. The last is one of the most active volcanoes in Chile. All of them are located along the eastern side of the Salar de Atacama, forming a generally north-south trending line of volcanoes that separate it from smaller endorheic basins. Features The salt flat encompasses , is about long and wide, which makes it the third largest in the world, after Salar de Uyuni in Bolivia (). and Salinas Grandes in Argentina (). Its average elevation is about 2,300 m above sea level. The topography of the core portion of the ''salar'' exhibits a high level of roughness, the result of e ...

Magma
Magma () is the molten or semi-molten natural material from which all igneous rocks are formed. Magma is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural satellites. Besides molten rock, magma may also contain suspended crystals and gas bubbles. Magma is produced by melting of the mantle or the crust in various tectonic settings, which on Earth include subduction zones, continental rift zones, mid-ocean ridges and hotspots. Mantle and crustal melts migrate upwards through the crust where they are thought to be stored in magma chambers or trans-crustal crystal-rich mush zones. During magma's storage in the crust, its composition may be modified by fractional crystallization, contamination with crustal melts, magma mixing, and degassing. Following its ascent through the crust, magma may feed a volcano and be extruded as lava, or it may solidify underground to form an intrusion, such as a ...

Láscar
Lascar is a stratovolcano in Chile within the Central Volcanic Zone of the Andes, a volcanic arc that spans Peru, Bolivia, Argentina and Chile. It is the most active volcano in the region, with records of eruptions going back to 1848. It is composed of two separate cones with several summit craters. The westernmost Volcanic crater, crater of the eastern cone is presently active. Volcanic activity is characterized by constant release of volcanic gas and occasional vulcanian eruptions. Lascar has been active since at least 56,000 years ago, though some argue for activity beginning 220,000 years ago. The first known activity occurred at the eastern cone and was characterized by lava flows, before shifting to the western cone where lava domes were emplaced. An eruption event known as Piedras Grandes was followed by the large Soncor eruption. A new western edifice was constructed on top of the Soncor vent, during the Holocene activity then shifted again to the eastern edifice and co ...
