Nevado El Cisne
The Nevado El Cisne or Nevado del Cisne (), also known as Paramillo el Cisne or Paramillo del Cisne (), is a volcano in the Central Ranges of the Andes in Colombia. Its summit is at an altitude of approximately . The mountain belongs to the Cisne-Morro Negro lava dome, a small volcanic complex near Nevado del Ruiz. Despite the ''nevado'' part of the name, indicating a permanently snow-capped mountain, the summit of El Cisne is now below the permanent snow line as a result of global warming, and it is no longer considered a true ''nevado''. Hence it is now commonly referred to as a ''paramillo''. Geology Nevado El Cisne is the summit of a small volcanic complex which includes El Cisne's sister peak, Morro Negro, and several subpeaks. They are small stratovolcanoes. The complex has well-preserved morphology with barely eroded lava flows, suggesting recent volcanic activity. Five emission centers have been identified as generators of lava flows. The lava flows are andesitic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Los Nevados National Natural Park
Los Nevados National Natural Park () is a national park located in the Cordillera Central of the Colombian Andes. The park features Colombia's highest and northernmost active volcanoes including the glacier-capped Nevado del Ruiz, Nevado del Tolima, and Nevado de Santa Isabel, and the formerly glaciated superpáramo peaks (''paramillos'') of Cisne, Santa Rosa and Quindío. Other elevated structures of volcanic origin within the park are Alto La Piraña, La Olleta, Cerro España, and the Peñas de Caracoli. Cerro Bravo and Cerro Machín are located outside the park but part of the same volcanic region. The park is located in the departments of Caldas, Quindío, Risaralda, Tolima and spans between the municipalities Manizales, Villamaría, Santa Rosa de Cabal, Pereira, Salento, Villahermosa, Anzoátegui, Santa Isabel, Murillo, Ibagué and Casabianca.

Geography Of Tolima Department
Geography (from Ancient Greek ; combining 'Earth' and 'write', literally 'Earth writing') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines." Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quaternary Colombia
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS), as well as the current and most recent of the twelve periods of the Phanerozoic eon. It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today); a proposed third epoch, the Anthropocene, was rejected in 2024 by IUGS, the governing body of the ICS. The Quaternary is typically defined by the Quaternary glaciation, the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive fo ...

Volcanoes Of Colombia
A volcano is commonly defined as a vent or fissure 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 because most of Earth's plate boundaries are underwater, most volcanoes 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 resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is stretching an ...

Mountains Of Colombia
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 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 climate, mountains t ...

INGEOMINAS
The Colombian Geological Survey (CGS) (; formerly known as INGEOMINAS) is a scientific agency of the Colombian government in charge of contributing to the socioeconomic development of the nation through research in basic and applied geosciences of the subsoil, the potential of its resources, evaluating and monitoring threats of geological origin, managing the geoscientific knowledge of the nation, and studying the nuclear and radioactive elements in Colombia. History The CGS was initially created as the ''National Scientific Commission'' () by the Congress of Colombia on December 22, in 1916, with the mission of mapping the geological resources of the nation and exploring the national territory in search of mineral deposits. Following a series of earthquakes throughout the nation in the early 1920s, the eruption of the Galeras volcano in 1925, and the growing mining and petroleum industry, the Colombian government decided to re-organize the National Scientific Commission in 193 ...

Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palestina Fault
The Palestina Fault () is a regional sinistral oblique thrust fault in the departments of Antioquia, Caldas and Bolívar in central Colombia. The fault has a total length of and runs along an average north-northeast to south-southwest strike of 017.8 ± 11 along the Central Ranges of the Colombian Andes. Description The Palestina Fault extends from the Serranía de San Lucas in the department of Antioquia in the north,Buitrago et al., 2014, p. 27 to the Nevado del Ruiz volcanic zone in the south. The Otú Norte and Bagre Norte Faults splay off the Palestina Fault.Buitrago et al., 2014, p. 26 It mainly extends along the eastern slope of the Central Ranges, displacing Paleozoic crystalline metamorphic rocks and, in lesser amounts, Mesozoic plutonic rocks. The oldest rocks are mainly in the western block, which elevates a probable Miocene erosion surface whose eroded remnants are characterized by aligned flat narrow benches and spurs.Paris et al., 2000a, p. 29 The fault forms ...
