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.

Pular (volcano)
Pular is a massive stratovolcano located in the Antofagasta Region of northern Chile, about 15 km west of the border with Argentina, which in this area is a straight line between the summits of Socompa volcano and ''Cerro del Rincón''. Pular, along with '' Cerro Pajonales'', forms a high volcanic ridge, which runs in a generally north-east to south-west direction for . Southward, following the same direction as the ridge, lies Socompa volcano. The ridge's crest forms a drainage divide between Salar de Atacama basin and ''Salar de Pular'' basin. This latter is a bowl-shaped basin enclosed on the east by Aracar volcano. In the Kunza language Pular means "The Eyebrow"Humberto Barrera, "Cerro Pular", ''American Alpine Journal'', 1974, p. 194.

Cerros De Incahuasi
Cerros de Incahuasi is a mountain with several summits located in the Antofagasta Region of Chile, near Sico Pass. The present–day mountain is the result of the partial collapse of an ancient volcanic edifice. The Incahuasi Sur volcano in this range was active 10.5 million years ago. It is associated with a volcanic belt and fault (geology), fault that extends southeastward from Incahuasi Sur, the Calama–Olacapato–El Toro fault.

Cerro 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.

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 ...

Rhyodacitic
Rhyodacite is a volcanic rock intermediate in composition between dacite and rhyolite. It is the extrusive equivalent of those plutonic rocks that are intermediate in composition between monzogranite and granodiorite. Rhyodacites form from rapid cooling of lava relatively rich in silica and low in alkali metal oxides. Description Under IUGS guidelines, rhyodacites are not formally defined in either the QAPF classification, used to classify igneous rocks by their mineral content, or the TAS classification, used to classify volcanic rocks chemically. However, the IUGS allows the use of the term to describe rocks close to the boundary between the rhyolite and dacite fields in each classification scheme. Rhyodacite then describes a fine-grained igneous rock containing between 20% and 60% quartz and in which plagioclase makes up about two-thirds of the total feldspar content. Such a rock will contain between 69% and 72% silica by weight. The U.S. Geological Survey defines rhyodaci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Antofagasta Region
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 pa ...

Ignimbrite
Ignimbrite is a type of volcanic rock, consisting of hardened tuff. Ignimbrites form from the deposits of pyroclastic flows, which are a hot suspension of particles and gases flowing rapidly from a volcano, driven by being denser than the surrounding atmosphere. New Zealand geologist Patrick Marshall (1869-1950) coined the term ''ignimbrite'' from the Latin ''igni-'' [fire] and ''imbri-'' [rain]. Ignimbrites are made of a very poorly sorted mixture of volcanic ash (or tuff when Lithification, lithified) and pumice lapilli, commonly with scattered lithic fragments. The ash is composed of glass shards and crystal fragments. Ignimbrites may be loose and unconsolidated, or lithified (solidified) rock called lapilli-tuff. Near the volcanic source, ignimbrites often contain thick accumulations of lithic blocks, and distally, many show meter-thick accumulations of rounded cobbles of pumice. Ignimbrites may be white, grey, pink, beige, brown, or black depending on their composition and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
