San José (volcano)
San José Volcano is the stratovolcano that gives its name to a massive volcanic group, at about from Santiago de Chile at the end of the Cajón del Maipo on the Chile-Argentina border. It lies on the south end of an approximately x complex that includes the La Engorda, Espiritu Santo, Plantat and Marmolejo volcanoes, the latter of which is located on the Northern end of the group.

Cajón Del Maipo
Cajón del Maipo is a canyon located in the Andean southeastern portion of the Santiago Metropolitan Region, Chile. It encompasses the upper Maipo River basin, where the river has entrenched itself in a narrow valley. The zone features a series of confluent rivers such as El Volcán River, Yeso River, and Colorado River, as well as other minor streams, including San Gabriel, Manzanito, Coyanco, El Sauce, El Manzano and San José. The main locality is San José de Maipo, the capital of the commune that includes all of the Andean sector of the Metropolitan Region. The valley ends close to Pirque and begins almost at the border with Argentina, where it is surrounded by some of the highest peaks in the region, including San José, Maipo, and Marmolejo Volcán Marmolejo is a high Pleistocene stratovolcano in the Andes on the border between Argentina and Chile. It is located NNE of the active San José volcano, and is the southernmost -plus peak in the world. The Argentine p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Active Volcanoes
An active volcano is a volcano which is either erupting or is likely to erupt in the future. An active volcano which is not currently erupting is known as a dormant volcano. Overview Tlocene Epoch. Most volcanoes are situated on the Pacific Ring of Fire. An estimated 500 million people live near active volcanoes. ''Historical time'' (or recorded history) is another timeframe for ''active''. However, the span of recorded history differs from region to region. In China and the Mediterranean, it reaches back nearly 3,000 years, but in the Pacific Northwest of the United States and Canada, it reaches back less than 300 years, and in Hawaii and New Zealand it is only around 200 years. The incomplete ''Catalogue of the Active Volcanoes of the World'', published in parts between 1951 and 1975 by the International Association of Volcanology, uses this definition, by which there are more than 500 active volcanoes. , the Smithsonian Global Volcanism Program recognizes 560 volcanoes with ...

Volcanoes Of Mendoza Province
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 (geology), hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tect ...

Mountains Of Mendoza Province
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 ...

Marmolejo
Volcán Marmolejo is a high Pleistocene stratovolcano in the Andes on the border between Argentina and Chile. It is located NNE of the active San José volcano, and is the southernmost -plus peak in the world. The Argentine portion is within the Argentinean protection area of Provincial Reserve for Multiple Use and Natural Recreation Manzano / Portillo de Piuquenes. It is on the border of two provinces: Argentinean province of Mendoza and Chilean province of Cordillera. Its slopes are within the administrative boundaries of the two cities: Argentinean city of Tunuyán and the Chilean commune of San José de Maipo. First ascent Marmolejo was first climbed by Hermann Sattler, Sebastian Krückel and Albrecht Maass (Germany) October 1, 1928. Elevation It has an official height of 6108 meters. Other data from available digital elevation models: SRTM yields 6097 metres, ASTER 6103 metres, ALOS 6085 metres and TanDEM-X 6129 metres. The height of the nearest key col is 4005 ...

Principal Cordillera
Principal Cordillera ( es, Cordillera Principal) is the Andean mountain range that makes up the boundary between Central Chile and neighbouring areas of Argentina. It is also a continental divide between the Atlantic and the Pacific watersheds. It extends in a north–south direction in the Argentine provinces of La Rioja, San Juan and Mendoza and the Chilean regions of Valparaíso, Santiago, O'Higgins and Maule. To the east of the Principal Cordillera lies the Frontal Cordillera which is fully in Argentina. Aconcagua, the tallest mountain outside Asia, lies in the Principal Cordillera. Geological history What is today the Principal Cordillera was once a depression that accumulated sediments.Charrier ''et al''. 2006, pp. 93–94. Lava flows from ancient volcanoes also found their way to the depression. Today these sequences of sedimentary Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's su ...
