Cordillera De Nahuelbuta
The Nahuelbuta Range or Cordillera de Nahuelbuta () is a mountain range in Bio-Bio and Araucania Region, southern Chile. It is located along the Pacific coast and forms part of the larger Chilean Coast Range. The name of the range derives from the Mapudungun words ''nahuel'' (jaguar) and ''futa'' (big) Historically Cordillera de Nahuelbuta and its surrounding valleys were the foci of the Arauco War. The Spanish designs for this region was to exploit the placer deposit In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. The name is from the Spanish word ''placer'', meaning "alluvial sand". Placer mi ...s of gold around the range using unfree Mapuche labour from the densely populated valleys. For this purpose the Spanish established a series of settlements and fortified houses around Cordillera de Nahuelbuta. See also * Arauco Basin * Coastal Batholith of central Ch ...

Araucaria Araucana
''Araucaria araucana'' (commonly called the monkey puzzle tree, monkey tail tree, piñonero, pewen or Chilean pine) is an evergreen tree growing to a trunk diameter of 1–1.5 m (3–5 ft) and a height of 30–40 m (100–130 ft). It is native to central and southern Chile and western Argentina. ''Araucaria araucana'' is the hardiest species in the conifer genus ''Araucaria''. Because of the prevalence of similar species in ancient prehistory, it is sometimes called a living fossil. It is also the national tree of Chile. Its conservation status was changed to Endangered by the IUCN in 2013 due to the dwindling population caused by logging, forest fires, and grazing. Description The leaves are thick, tough, and scale-like, triangular, long, broad at the base, and with sharp edges and tips. According to Lusk, the leaves have an average lifespan of 24 years and so cover most of the tree except for the older branches. It is usually dioecious, with the male and f ...

Jaguar
The jaguar (''Panthera onca'') is a large cat species and the only living member of the genus ''Panthera'' native to the Americas. With a body length of up to and a weight of up to , it is the largest cat species in the Americas and the third largest in the world. Its distinctively marked coat features pale yellow to tan colored fur covered by spots that transition to rosettes on the sides, although a melanistic black coat appears in some individuals. The jaguar's powerful bite allows it to pierce the carapaces of turtles and tortoises, and to employ an unusual killing method: it bites directly through the skull of mammalian prey between the ears to deliver a fatal blow to the brain. The modern jaguar's ancestors probably entered the Americas from Eurasia during the Early Pleistocene via the land bridge that once spanned the Bering Strait. Today, the jaguar's range extends from core Southwestern United States across Mexico and much of Central America, the Amazon rainfor ...

Mountain Ranges Of Chile
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 ...

Nahuelbuta National Park
Nahuelbuta National Park () is one of the few parks located in La Araucanía Region of Chile's Coastal Mountain Range. It sits atop the highest part of the Cordillera de Nahuelbuta. Created in 1939, it consists of 6,832 hectares situated just 162 km northeast of Temuco. Nahuelbuta (Mapuche for "big tiger") is a sanctuary for monkey puzzle trees, with specimens dating back 2,000 years. Flora In addition to monkey puzzle trees, the park is also home to coigüe, ñirre, oak, lenga, orchids, carnivorous plants. Fauna The park provides habitat for the mountain lion, the pudú, a small Chilean deer, and Darwin's fox. Among the birds are the Magellanic woodpecker, the Andean tapaculo and the chucao tapaculo. Destinations The park features 30 roads and 15 trails that can be explored by car or foot. The National Forest Corporation (Chile) information center and camping area are both found in Pehuenco, where the most popular route begins. Following it will treat you to over fou ...

Coastal Batholith Of Central Chile
The Coastal Batholith of central Chile is a group of plutons in the Chilean Coast Range of Central Chile appearing contiguously from 33° S to 38° S. At a latitude of 40° S an outlying group of plutons of the batholith appear in a more eastward position in the Andes. Together with the Elqui-Limarí Batholith and the Colangüil Batholith, the Coastal Batholith of central Chile is a remnant of the volcanic arcs that erupted the volcanic material of the Choiyoi Group. During the Permian the zone of arc magmatism moved from the Coastal Batholith 350 km inland reaching San Rafael about 280 million years ago. The batholith is emplaced amidst metamorphic rocks belonging to a Paleozoic accretionary complex. The northern parts are of the batholith are themselves intruded by Jurassic gabbros. Rocks of the batholith belong to the calc-alkaline magma series The calc-alkaline magma series is one of two main subdivisions of the subalkaline magma series, the other subalkaline magma series ...

Arauco Basin
The Arauco Basin ( es, Cuenca de Arauco) is a sediment-filled depression –a sedimentary basin– in south-central Chile. In the context of plate tectonics it is classified as a forearc basin. The basin has an approximate area of and at its deeper parts the surface of its sedimentary fill reaches below sea-level. The basin is interpreted as being part of an uplifted part of the continental shelf. To the west it bounds an active accretionary prism that lies next to the Chile trench and to the east it bounds metamorphic basement representing a fossil Paleozoic accretionary complex that has been intruded by the Coastal Batholith of central Chile. Traditionally the centre of coal mining in Chile, large-scale coal mining in Arauco Basin ended in the 1990s.Explotacion Re ...

Placer Deposit
In geology, a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation from a specific source rock during sedimentary processes. The name is from the Spanish word ''placer'', meaning "alluvial sand". Placer mining is an important source of gold, and was the main technique used in the early years of many gold rushes, including the California Gold Rush. Types of placer deposits include alluvium, eluvium, beach placers, aeolian placers and paleo-placers. Placer materials must be both dense and resistant to weathering processes. To accumulate in placers, mineral particles must have a specific gravity above 2.58. Placer environments typically contain black sand, a conspicuous shiny black mixture of iron oxides, mostly magnetite with variable amounts of ilmenite and hematite. Valuable mineral components often occurring with black sands are monazite, rutile, zircon, chromite, wolframite, and cassiterite. Early mining operations were likely a re ...

Arauco War
The Arauco War was a long-running conflict between colonial Spaniards and the Mapuche people, mostly fought in the Araucanía. The conflict began at first as a reaction to the Spanish conquerors attempting to establish cities and force Mapuches into servitude. It subsequently evolved over time into phases comprising drawn-out sieges, slave-hunting expeditions, pillaging raids, punitive expeditions, and renewed Spanish attempts to secure lost territories. Abduction of women and war rape was common on both sides. After many initial Spanish successes in penetrating Mapuche territory, the Battle of Curalaba in 1598 and the following destruction of the Seven Cities marked a turning point in the war leading to the establishment of a clear frontier between the Spanish domains and the land of the independent Mapuche. From the 17th to the late 18th century a series of parliaments were held between royal governors and Mapuche lonkos and the war devolved to sporadic pillaging car ...

Mapudungun
Mapuche (, Mapuche & Spanish: , or Mapudungun; from ' 'land' and ' 'speak, speech') is an Araucanian language related to Huilliche spoken in south-central Chile and west-central Argentina by the Mapuche people (from ''mapu'' 'land' and ''che'' 'people'). It is also spelled Mapuzugun and Mapudungu. It was formerly known as Araucanian, the name given to the Mapuche by the Spaniards; the Mapuche avoid it as a remnant of Spanish colonialism. Mapudungun is not an official language of the countries Chile and Argentina, receiving virtually no government support throughout its history. However, since 2013, Mapuche, along with Spanish, has been granted the status of an official language by the local government of Galvarino, one of the many Communes of Chile. It is not used as a language of instruction in either country's educational system despite the Chilean government's commitment to provide full access to education in Mapuche areas in southern Chile. There is an ongoing political ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .
