Laguna De Cotacotani
Laguna de Cotacotani (Hispanicized expression) or Quta Qutani (Aymara language, Aymara ''quta'' lake, the reduplication signifies there is a group or complex of something, ''-ni'' is a suffix to indicate ownership, "the one with a group of lakes" ) is a lakeIt is considered as one or several lakes, depending on sources. located in the Andes, Andean Altiplano of the Parinacota Province, Arica-Parinacota Region, Chile. It lies 4 km northwest of Chungará Lake, which is one of the highest lakes in the world and is surrounded by several volcanoes, such as the Payachata volcanic group (Parinacota Volcano, Parinacota and Pomerape), Nevado Sajama, Sajama volcano and Wallatiri. Cotacotani is separated from the lake Chungará by a strip of volcanic rock and receives groundwater inflow from that lake, however its major sources are ''Benedicto Morales River'' and ''El Encuentro Creek''. Cotacotani Lake's main feature is the considerable number of islands and islets that it holds, which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arica-Parinacota Region
The Arica y Parinacota Region ( es, link=no, Región de Arica y Parinacota ) is one of Chile's 16 first order administrative divisions. It comprises two provinces, Arica and Parinacota. It borders Peru's Department of Tacna to the north, Bolivia's La Paz and Oruro departments to the east and Chile's Tarapacá Region to the south. Arica y Parinacota is the 5th smallest, the 3rd least populous and the 6th least densely populated of the regions of Chile. Arica is the region's capital and largest city. The region was a former Peruvian province, which was occupied by Chile under the 1883 Treaty of Ancón at the close of the War of the Pacific, and then formally annexed in 1929 by the Treaty of Lima. Following annexation, Arica y Parinacota went through a process of forced acculturation known as Chilenization with the aim of creating a dominance of Chilean traditions and culture. Administration In 2007, the region was subdivided to create the Arica y Parinacota region and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andesite
Andesite () is a volcanic rock of intermediate composition. In a general sense, it is the intermediate type between silica-poor basalt and silica-rich rhyolite. It is fine-grained (aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende. Andesite is the extrusive equivalent of plutonic diorite. Characteristic of subduction zones, andesite represents the dominant rock type in island arcs. The average composition of the continental crust is andesitic. Along with basalts, andesites are a component of the Martian crust. The name ''andesite'' is derived from the Andes mountain range, where this rock type is found in abundance. It was first applied by Christian Leopold von Buch in 1826. Description Andesite is an aphanitic (fine-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspathoid by volume, with at least 65% of the fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Before Present
Before Present (BP) years, or "years before present", is a time scale used mainly in archaeology, geology and other scientific disciplines to specify when events occurred relative to the origin of practical radiocarbon dating in the 1950s. Because the "present" time changes, standard practice is to use 1 January 1950 as the commencement date (epoch) of the age scale. The abbreviation "BP" has been interpreted retrospectively as "Before Physics", which refers to the time before nuclear weapons testing artificially altered the proportion of the carbon isotopes in the atmosphere, which scientists must now account for. In a convention that is not always observed, many sources restrict the use of BP dates to those produced with radiocarbon dating; the alternative notation RCYBP stands for the explicit "radio carbon years before present". Usage The BP scale is sometimes used for dates established by means other than radiocarbon dating, such as stratigraphy. This usage differs from t ...

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated grade (slope), slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the She ...

Guane Guane
Guane is a municipality and town in the Pinar del Río Province of Cuba. It was founded in 1602. Geography The municipality is divided into the barrios of Cabo de San Antonio y La Fe, Catalina, Cortés, Hato de Guane, Isabel Rubio (Paso Real de Guane), Juan Gómez, La Grifa, Las Martinas, Los Acostas, Manuel Lazo (Cayuco), Portales, Pueblo, Punta de la Sierra, Sábalo and Tenería.

Before it was renamed Pinar del Río in 1774, the area was known as the old colonial capital of Guane. It was the main city of Filipino migrants to Cuba, who were known as Chinos Manila among the local population. The Filipinos worked the huge tobacco plantations much as they did in their home country, in the present provinces of Ilocos Sur, Tarlac, Ilocos Norte, Cagayan and Isabela. During that time, the Spanish co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lauca National Park
Lauca National Park is located in Chile's far north, in the Andean range. It encompasses an area of 1,379 km2 of altiplano and mountains, the latter consisting mainly of enormous volcanoes. Las Vicuñas National Reserve is its neighbour to the south. Both protected areas, along with Salar de Surire Natural Monument, form Lauca Biosphere Reserve. The park borders Sajama National Park in Bolivia. Position The park is located east of Arica and west of Putre, between 18°03' S - 18°27' S and 69°02' W - 69°39' W, and to msnm. Geography One of the main attractions of the park is the small lacustrine area formed by Chungará and Cotacotani lakes, which lies at the foothills of the Payachata volcanic group. Other majestic volcanoes forming part of the national park are the Guallatiri and the Acotango. Lauca features include archaeological sites, lava fields and volcanic calderas. Within the park is located the town of Parinacota with its colonial church. The headwaters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
