Incahuasi Municipality
Incahuasi (; possibly from Quechua: ''inka'' Inca, ''wasi'' house) is a volcanic mountain in the Andes of South America. It lies on the border of the Catamarca Province of Argentina and the Atacama Region of Chile. Incahuasi has a summit elevation of above sea level. The volcano consists of a caldera and two stratovolcanoes. Four pyroclastic cones located to the northeast have produced basalt- andesite lava flows that cover an area of . Geography and geology Incahuasi lies on the border between Argentina and Chile, close to Paso San Francisco. A major road crosses the border there. Regional Incahuasi is part of the Central Volcanic Zone of the Andes, together with about 110 other Quaternary volcanoes, and lies in the southern sector of this zone; other volcanic zones in the Andes are the Northern Volcanic Zone, the Southern Volcanic Zone, and the Austral Volcanic Zone.

Catamarca Province
Catamarca () is a province of Argentina, located in the northwest of the country. The province had a population of 334,568 as per the , and covers an area of 102,602 km2. Its literacy rate is 95.5%. Neighbouring provinces are (clockwise, from the north): Salta, Tucumán, Santiago del Estero, Córdoba, and La Rioja. To the west it borders the country of Chile. The capital is San Fernando del Valle de Catamarca, usually shortened to Catamarca. Other important cities include Andalgalá, Tinogasta, and Belén. Geography Most of Catamarca's territory of 102,602 square kilometers (2.7% of the country total), is covered by mountains (80%), which can be grouped into four clearly differentiated systems: the Pampean sierras, in the east and center; the Narváez-Cerro Negro-Famatina system, in the west; the cordilleran-Catamarca area of transition, in the western extreme; the Puna, an elevated portion, in the northwest. Located in an arid and semi-arid climate zone, the scarce w ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Central Volcanic Zone
The Andean Volcanic Belt is a major volcanic belt along the Andean cordillera in Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru. It is formed as a result of subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate. The belt is subdivided into four main volcanic zones which are separated by volcanic gaps. The volcanoes of the belt are diverse in terms of activity style, products, and morphology. While some differences can be explained by which volcanic zone a volcano belongs to, there are significant differences within volcanic zones and even between neighboring volcanoes. Despite being a type location for calc-alkalic and subduction volcanism, the Andean Volcanic Belt has a broad range of volcano-tectonic settings, as it has rift systems and extensional zones, transpressional faults, subduction of mid-ocean ridges and seamount chains as well as a large range of crustal thicknesses and magma ascent paths and different amounts of crustal assim ...

Juan Fernández Ridge
The Juan Fernández Ridge is a volcanic island and seamount chain on the Nazca Plate. It runs in a west–east direction from the Juan Fernández hotspot to the Peru–Chile Trench at a latitude of 33° S near Valparaíso. The Juan Fernández Islands are the only seamounts that reach the surface. Subduction of the ridge beneath South America is thought to have caused the Pampean flat-slab The Pampean flat-slab is the low angle subduction of oceanic lithosphere beneath Northern Argentina. The Pampean flat-slab is one of three flat slabs in South America, the other being the Peruvian flat-slab and the Bucaramanga flat-slab. It is ... and its associated inland tectonic deformation and reduced magmatic activity.

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Falso Azufre
Falso Azufre is a complex volcano at the border of Argentina and Chile. Falso Azufre is elongated in east–west direction and contains craters and lava domes; most craters have diameters of with the exception of the main crater, which is wide.Grosse, et al. 2018, p. 12 The highest summit Cerro Falso Azufre lies at the western end in Chile, which has mostly generated pyroclastic material from craters. The probably youngest segment of the volcano is the eastern section in Argentina, where two lava domes and two cones are located; these form the Dos Conos volcano. Some lava flows linked to Dos Conos are up to long.Grosse, et al. 2018, p. 13 The oldest is known as the Kunstmann edifice on the northwestern side of Falso Azufre; Kunstmann volcano features a wide scar formed by a sector collapse. Falso Azufre with a base surface of is one of the biggest volcanoes in the area. The presence of two oppositely curved vent alignments gives the complex an arc-like shape which reaches h ...

Ojos Del Salado
Nevado Ojos del Salado is a dormant complex volcano in the Andes on the Argentina–Chile border. It is the highest volcano on Earth and the highest peak in Chile. The upper reaches of Ojos del Salado consist of several overlapping lava domes, lava flows and volcanic craters, with an only sparse ice cover. The complex extends over an area of and its highest summit reaches an altitude of above sea level. Numerous other volcanoes rise around Ojos del Salado. Due to its location near the Arid Diagonal of South America, the mountain has extremely dry conditions, which prevent the formation of glaciers and a permanent snow cover. Despite the arid climate, there is a permanent crater lake about in diameter at an elevation of - within the summit crater and east of the main summit. This is the highest lake of any kind in the world. Owing to its altitude and the desiccated climate, the mountain lacks vegetation. Ojos del Salado was volcanically active during the Pleistocene and Holo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
