Cordillera Oriental (Ecuador)
{{Ecuador-geo-stub ...
The Cordillera Real (also Cordillera of Quito, Cordillera Central of Ecuador) is a chain of mountains in the Andes of Ecuador, the largest of them volcanic. They are continued by the Cordillera Central of Peru to the south and the Cordillera Central of Colombia to the north. The Cordillera Real includes Antisana, Cotopaxi, and Cayambe, while Chimborazo is in the Cordillera Occidental. The geology of the Cordillera Real includes metamorphic rock of sedimentary origin in addition to S-type granites dated to the early Mesozoic (>200 million years ago).

Cotopaxi 1
Cotopaxi () is an active stratovolcano in the Andes Mountains, located near Latacunga city of Cotopaxi Province, about south of Quito, and northeast of the city of Latacunga, Ecuador. It is the second highest summit in Ecuador (after Chimborazo), reaching a height of . Cotopaxi is among the highest active volcanoes in the world. Cotopaxi is known to have erupted 87 times, resulting in the creation of numerous valleys formed by lahars (mudflows) around the volcano. An ongoing eruption began on 21 October 2022. At the end of February 2023, the Geophysical Institute of Ecuador reported that Cotopaxi had produced around 8,000 earthquakes since October 21, 2022, amounting to 1,600 events per month. Description On a clear day, Cotopaxi is clearly visible on the skyline from Latacunga and Quito. It is part of the chain of volcanoes around the Pacific Plate known as the Pacific Ring of Fire. It has an almost symmetrical cone that rises from a highland plain of about , with a wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Metamorphic Rock
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock ( protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and dist ...

Mesozoic
The Mesozoic Era is the Era (geology), era of Earth's Geologic time scale, geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Period (geology), Periods. It is characterized by the dominance of archosaurian reptiles such as the dinosaurs, and of Gymnosperm, gymnosperms such as cycads, ginkgoaceae and Araucariaceae, araucarian conifers; a hot Greenhouse and icehouse earth, greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since Cambrian explosion, complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic. The era began in the wake of the Permian–Triassic extinction event, the largest mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, Pterosaur, pterosaurs, Mosasaur, mosasaurs, and Plesiosaur, plesiosaurs. The Mesozoic was a time of significant tectonic, climatic, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
S-type Granite
S-type granites are a category of granites first proposed in 1974. They are recognized by a specific set of Mineralogy, mineralogical, Geochemistry, geochemical, textural, and Isotope, isotopic characteristics. S-type granites are over-saturated in aluminium, with an ASI index greater than 1.1 where ASI = Al2O3 / (CaO + Na2O +K2O) in mol percent; Petrography, petrographic features are representative of the chemical composition of the initial magma as originally put forth by Chappell and White are summarized in their table 1. Mineralogy Major minerals (present in amounts > 5 volume%) Like all Granite, granites, the modal mineralogy of S-type granites are dominated by Alkali feldspar, alkali- and plagioclase feldspars and quartz. Thus, S-type granites are silica over-saturated (contain quartz), and do not contain feldspathoids. An interesting feature of S-type granites, at the hand sample scale, is that alkali-feldspars are typically white in color (rather than pink) excluding sa ...

Protolith
A protolith () is the original, unmetamorphosed rock from which a given metamorphic rock is formed. For example, the protolith of a slate is a shale or mudstone. Metamorphic rocks can be derived from any other kind of non-metamorphic rock and thus there is a wide variety of protoliths. Identifying a protolith is a major aim of metamorphic geology. Protoliths are non-metamorphic rocks and have no protoliths themselves. The non-metamorphic rocks fall into two classes: sedimentary rocks, formed from sediment, and igneous rocks, formed from magma. The source of the sediment of a sedimentary rock is termed its provenance Provenance () is the chronology of the ownership, custody or location of a historical object. The term was originally mostly used in relation to works of art, but is now used in similar senses in a wide range of fields, including archaeology, p .... Magmatic protoliths can be further divided into three categories: ultramafic rock, mafic rock, and quartzo- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sedimentary Rock
Sedimentary rocks are types of rock (geology), rock formed by the cementation (geology), cementation of sediments—i.e. particles made of minerals (geological detritus) or organic matter (biological detritus)—that have been accumulated or deposited at Earth's surface. Sedimentation is any process that causes these particles to settle in place. Geological detritus originates from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or Mass wasting, mass movement, which are called agents of denudation. Biological detritus is formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur when dissolved minerals precipitate from aqueous solution, water solution. The sedimentary rock cover of ...

Andes
The Andes ( ), Andes Mountains or Andean Mountain Range (; ) are the List of longest mountain chains on Earth, longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long and wide (widest between 18th parallel south, 18°S and 20th parallel south, 20°S latitude) and has an average height of about . The Andes extend from south to north through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela. Along their length, the Andes are split into several ranges, separated by intermediate depression (geology), depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, Mérida, Mérida, El Alto, and La Paz. The Altiplano, Altiplano Plateau is the world's second highest after the Tibetan Plateau. These ranges are in turn grouped into three majo ...

Chimborazo (volcano)
Chimborazo () is a stratovolcano situated in Ecuador in the Cordillera Occidental range of the Andes. Its last known eruption is believed to have occurred around AD 550. Although not the tallest mountain in the Andes or on Earth relative to sea level, its summit is the farthest point on Earth's surface from the Earth's center due to its location along the planet's equatorial bulge. Chimborazo's height from sea level is 6,263 m (20,548 ft), well below that of Mount Everest at 8,849 m (29,031 ft). Chimborazo is the highest mountain in Ecuador and the 39th-highest peak in the entire Andes. It is a popular destination for mountaineering due to its challenging climbing routes, which involve traversing snow, ice, and rocky terrain. Etymology Several theories regarding the origin of the name Chimborazo exist. In many dialects of Quechua, "chimba" means "on the other side" as in "on the other side of the river" or "on the opposite bank". Other dialects pronounce this word ...

Cayambe (volcano)
Cayambe or Volcán Cayambe is a volcano in Ecuador, in the Cordillera Central, a range of the Ecuadorian Andes. It is located in Pichincha Province, some northeast of Quito. It is the third-highest mountain in Ecuador, at an elevation of above sea level. Cayambe, which has a permanent snow cap, is a Holocene compound volcano which last erupted in March 1786. At , its south slope is the highest point in the world crossed by the Equator, and the only point on the Equator with snow cover. The ice cap covers an area of about and there are glaciers on the eastern flank descending to about , whereas those on the drier western flank reach about . The volcano and most of its slopes are within the Cayambe Coca Ecological Reserve. Cayambe was first climbed by British adventurer Edward Whymper and his two Italian guides and companions Jean-Antoine Carrel and Louis Carrel in 1880. They made first ascents of most of the volcanoes in Ecuador. Cayambe remains a favorite of mountaineer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
