Volcano
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 pla ...

Barro Negro (volcano)
Barro Negro is a scoria cone in the northern Puna of Argentina. About way from Abra Pampa, it is high and is no older than the underlying 6.6 mya Las Termas ignimbrite from Coranzulí caldera. It has generated two lava flows, one long extending southsoutheastward. The other northeastward is heavily eroded and only isolated lava plateaus are left. The lavas erupted from the cone are porphyric trachyandesite-basalt of shoshonitic composition. They contain pyroxene and olivine phenocrysts with subordinate microphenocrysts of plagioclase and phlogopite and inclusions of gray minerals. The magmas generating this volcanism are primitive and may be oceanic crust Oceanic crust is the uppermost layer of the oceanic portion of the tectonic plates. It is composed of the upper oceanic crust, with pillow lavas and a dike complex, and the lower oceanic crust, composed of troctolite, gabbro and ultramafic c ...-derived melts with some crustal contamination.

Cerro Panizos
Panizos is a Late Miocene caldera in the Potosí Department of Bolivia and the Jujuy Province of Argentina. It is part of the Altiplano-Puna volcanic complex of the Central Volcanic Zone in the Andes. 50 volcanoes active in recent times are found in the Central Volcanic Zone, and several major caldera complexes are situated in the area. The caldera is located in a difficult-to-access part of the Andes. Panizos and the majority of these volcanoes are formed by the subduction of the oceanic Nazca Plate under the continental South American continental lithosphere. The caldera is located east of the main arc and is supplied chiefly by dacite magmas. Beneath Panizos lie Tertiary ignimbrites and a Paleozoic sedimentary basement. The huge Panizos ignimbrite erupted by Cerro Panizos has a minimum volume of . It erupted during an event 6.71 ± 0.04 mya and was preceded by another ignimbrite 7.9 mya ago. The last activity is a lava flow 6.1 mya ago. The caldera is hidden beneath a shield ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerro Morado
Cerro Morado is a monogenetic volcanic field, in Argentina. It is part of a group of mafic volcanic centres in the Altiplano-Puna region, which is dominated by silicic rocks such as dacitic - rhyolitic rocks. The field was formed during eruptions 6.4 million years ago which probably lasted from half a year to several years. These eruptions formed scoria cones and a plateau of lava flows. Geology and geography The Cerro Morado volcanic field is located in northwestern Argentina, in the Jujuy Province. The town of is located within the volcanic field. The frontier with Chile lies approximately west of the volcanic field. The Altiplano and the adjacent southern Puna has experienced mafic volcanism during the Cenozoic. Most of this volcanism occurred in the southern segment, but the northern segment has also experienced mafic volcanism mostly associated with major volcanic centres and smaller volcanic fields such as Cerro Morado and Cerro Bitiche. Mafic lava flows however tend t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerro Escorial
Cerro Escorial is a stratovolcano at the border of Argentina and Chile. It is part of the Corrida de Cori volcanic group and its youngest member. A well-preserved crater forms its summit area. Lava flows are found on the Chilean and smaller ones on the Argentinian side, the former reaching as far as from the volcano. One of these is dated 342,000 years ago by argon-argon dating. Off the western coast of South America, the Nazca Plate subducts beneath the South America Plate. This process has given rise to the Andes mountain chain and the Altiplano-Altiplano, Puna high plateau, which formed through shortening of the Crust (geology), crust that lasted until 1 million years ago. Cerro Escorial rises from the Puna, which is dissected at Cerro Escorial by the Archibarca lineament; it is a strike-slip fault that has facilitated the ascent of magma. Andesite lavas were erupted during the Miocene and Pliocene. Hydrothermal alteration has affected an area from the crater. A Plinian er ...

Cerro El Cóndor
Cerro El Cóndor is a stratovolcano in Argentina. Cerro El Cóndor is a remote peak in the Argentine Puna de Atacama. As such it was probably the last major 6000m+ peak in the Andes to be climbed, with the summit reaching a height of . The volcano has the form of a massif (which covers a surface of ) constructed by two separate volcanoes; the older edifice forms parts of the northern and eastern flanks which are cut by scarps interpreted as caldera remnants.Grosse ''et al.'' 2018, p.14 The summit region is formed by the newer edifice, and features a series of craters with diameters of and a cover of pyroclastic material and scoria. Also part of the newer phase are extensive lava flows which form the western and parts of the eastern and southern slopes and reach distances of from the summit.Grosse ''et al.'' 2018, p.15 Surrounding volcanoes include Condorito (which is considered to be part of the old El Cóndor volcano), Falso Azufre and Laguna Escondida which have constraine ...

Monogenetic Volcano
A monogenetic volcanic field is a type of volcanic field consisting of a group of small monogenetic volcanoes, each of which erupts only once, as opposed to polygenetic volcanoes, which erupt repeatedly over a period of time. The small monogenetic volcanoes of these fields are the most common subaerial volcanic landform. Many monogenetic volcanoes are cinder cones, often with lava flows, such as Parícutin in the Michoacán-Guanajuato volcanic field, which erupted from 1943 to 1952. Some monogenetic volcanoes are small lava shields, such as Rangitoto Island in the Auckland volcanic field. Other monogenetic volcanoes are tuff rings or maars. A monogenetic field typically contains between ten and a hundred volcanoes. The Michoacán-Guanajuato field in Mexico contains more than a thousand volcanoes and is exceptionally large. Monogenetic fields occur only where the magma supply to the volcano is low or where vents are not close enough or large enough to develop plumbing system ...

Cerro De Los Chenques
Cerro de los Chenques is a monogenetic volcano in the Chubut Province, Argentina, which was considered to be of Holocene age but was later re-dated to be of lower Pleistocene age. The volcano developed on a basement formed by Mesoproterozoic and Neoproterozoic rocks and more recent volcanic and granitic formations. The volcano is source of lava flows and pyroclastics; the former covered an area of about . The cone is accompanied by hills that may be additional cones and consists of layers of lava and pyroclastic material. The cone has a breach on its northeastern side. Cerro de los Chenques has erupted rocks ranging from alkali basalt to basanite, which contain phenocrysts ranging from clinopyroxene, olivine and plagioclase. It is considered part of the Patagonian basaltic volcanics, which take place behind the main volcanic arc and are considered to be backarc volcanism. Such volcanics take the form of large volcanic plateaus. These volcanic are noted for their xenoliths which ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerro Bitiche
Cerro Bitiche is a volcanic field in Argentina. It is located east of the Central Volcanic Zone away from the volcanic arc within the Altiplano-Puna volcanic complex (APVC), close to Zapaleri volcano. The field is formed by seven scoria cones and lava flows, of andesite-basaltic andesite composition. The field was formed by volcanism contemporaneous with the ignimbrite volcanism of the APVC, with Cerro Guacha and La Pacana calderas being located nearby. Geography and Geology Regional setting Cerro Bitiche is located in the area of the northern Puna-southern Altiplano, within Argentina and close to the tripoint with Bolivia and Chile. The Altiplano-Puna highland with horizontal dimensions of and average altitudes of is the second highest plain in the world. Zapaleri and the Rio Zapaleri are located northwest of Bitiche. The field is located behind the main volcanic arc of the Central Volcanic Zone. The region is the site of the Miocene Altiplano-Puna volcanic comp ...

Cerro Blanco (volcano)
Cerro Blanco (, "White Hill") is a caldera in the Andes of the Catamarca Province in Argentina. Part of the Central Volcanic Zone of the Andes, it is a volcano collapse structure located at an altitude of in a depression. The caldera is associated with a less well-defined caldera to the south and several lava domes. The caldera has been active for the last eight million years, and eruptions have created several ignimbrites. An eruption occurred 73,000 years ago and formed the Campo de la Piedra Pómez ignimbrite layer. About 2,300 ± 160 BCE, the largest known volcanic eruption of the Central Andes, with a Volcanic Explosivity Index, VEI-7, occurred at Cerro Blanco, forming the most recent caldera as well as thick ignimbrite layers. About of tephra were erupted then. The volcano has been dormant since then with some Deformation (volcanology), deformation and geothermal activity. A major future eruption would put nearby communities to the south at risk. The volcano is also kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerro Bayo Complex
Cerro Bayo is a complex volcano on the northern part border between Argentina and Chile. It consists of four overlapping stratovolcanoes along a north–south line. The main volcano face is located on the Argentine side, thought the summit of the complex is just west of the border, in Chile. The volcano is about 800,000 years old, but it is associated with ongoing ground uplift encompassing also the more northerly Lastarria and Cordón del Azufre volcanoes. The high summit is the source of two viscous dacitic lava flows with prominent levees that traveled to the north. In 2007 a steam eruption were observed by researchers investigating nearby salt pans such as Salar Ignorado.

Cerro Archibarca
Cerro Archibarca is a volcano in the Andes. It covers a surface area of . Lava flows descend from a conical edifice. It was active 11 million years ago. The youngest deposits are eroded andesites on the northern side. A major volcaniclastic unit is associated with Archibarca, named the La Torre formation after the valley where its lower bright red unit reaches a thickness of . The red unit is formed from unconsolidated pyroclastics with spherical clasts ( up to ). Granite and pumice are materials also present in this unit. The upper white unit is a thick pyroclastic flow from Archibarca. A thick rhyolitic flow with banding structures is also present as well as an associated lava dome that intruded the La Torre formation on the volcano's southern side. Andesites from this volcano are partly derived from crustal assimilation, with the crustal component constituting 40% of total rock. The Caballo Muerto and Archibarca ignimbrite Ignimbrite is a type of volcanic rock, con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
