ñadi
300px, The archaeological site of Monte Verde is in a zone of ñadi soils. Ñadi is a type of soil and a phytogeographic zone of Southern Chile. Ñadi soils are located in the Chilean Central Valley of Los Lagos Region, specifically between the moraines left by the region's most recent glaciation (the Llanquihue glaciation) and those of the penultimate glaciation (the Santa María glaciation). Ñadis have an impermeable layer, usually called ''fierrillo''. In more technical terms this layer is a placic horizon that is chiefly made up by the minerals goethite and ferrihydrite. Ñadi soils are found between the latitudes 38 to 43° S. See also *Lahuen Ñadi Natural Monument Lahuen Ñadi Natural Monument is a protected ñadi area in Los Lagos Region of southern Chile.

Llanquihue Glaciation
The last glacial period and its associated glaciation is known in southern Chile as the Llanquihue glaciation (). Its type area lies west of Llanquihue Lake where various drifts or end moraine systems belonging to the last glacial period have been identified. The glaciation is the last episode of existence of the Patagonian Ice Sheet. Around Nahuel Huapi Lake the equivalent glaciation is known as the Nahuel Huapi Drift. The preceding interglacial is known as the Valdivia interglacial after its type locality of Valdivia. General characteristics The characteristics of the glaciation differ according to latitude. In Central Chile, south of Atacama Desert, the extent of the Llanquihue glaciation was controlled by precipitation which increases to the south. Maximum glaciers advances were not synchronous across the whole latitudinal gradient as they were triggered by north and southward shifts in the moisture-bringing Westerlies and its storm tracks.

Chilean Central Valley
The Central Valley (), Intermediate Depression, or Longitudinal Valley is the depression between the Chilean Coastal Range and the Andes Mountains. The Chilean Central Valley extends from the border with Peru to Puerto Montt in southern Chile, with a notable interruption at Norte Chico (27°20'–33°00' S). South of Puerto Montt the valley has a continuation as a series of marine basins up to the isthmus of Ofqui. Some of Chile's most populous cities lie within the valley including Santiago, Temuco, Rancagua, Talca and Chillán. Northern section (18°30'–27°20' S) In northernmost Chile the central valley is made up of the Pampitas, a series of small flats dissected by deep valleys.Börger, p. 40. Immediately south of the Pampitas, in Tarapacá Region and northern of Antofagasta Region, the Central Valley is known as Pampa del Tamarugal.Börger, p. 41.Brüggen, p. 6.

Ferrihydrite
Ferrihydrite (Fh) is a widespread hydrous ferric oxyhydroxide mineral at the Earth's surface, and a likely constituent in extraterrestrial materials. It forms in several types of environments, from freshwater to marine systems, aquifers to hydrothermal hot springs and scales, soils, and areas affected by mining. It can be precipitated directly from oxygenated iron-rich aqueous solutions, or by bacteria either as a result of a metabolic activity or passive sorption of dissolved iron followed by nucleation reactions. Ferrihydrite also occurs in the core of the ferritin protein from many living organisms, for the purpose of intra-cellular iron storage. Structure Ferrihydrite only exists as a fine grained and highly defective nanomaterial. The powder X-ray diffraction pattern of Fh contains two scattering bands in its most disordered state, and a maximum of six strong lines in its most crystalline state. The principal difference between these two diffraction end-members, commonly nam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Los Lagos Region
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] |
Soil In Chile
Soil, also commonly referred to as earth, is a mixture of organic matter, minerals, gases, water, and organisms that together support the life of plants and Soil biology, soil organisms. Some scientific definitions distinguish dirt from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid collection of minerals and organic matter (the soil matrix), as well as a Porosity, porous phase that holds Soil gas, gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state of matter, state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, terrain, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and s ...

Geography Of Chile
The geography of Chile is extremely diverse, as the country extends from a latitude of 17°South to Cape Horn at 56° and from the Pacific Ocean in the west to the Andes in the east. Chile is situated in southern South America, bordering the South Pacific Ocean and a small part of the South Atlantic Ocean. Chile's territorial shape is considered among the world's most unusual; from north to south, the country extends , and yet it only averages in width. Chile reaches from the middle of South America's west coast straight down to the southern tip of the continent, where it curves slightly eastward. The Diego Ramírez Islands and Cape Horn, the southernmost points in the Americas where the Pacific and Atlantic oceans meet, are Chilean territory. Chile's northern neighbors are Peru and Bolivia, and its border with Argentina to the east, at , is the world's third-longest. The total land area is . The very long coastline of gives Chile the 11th largest exclusive economic zone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agricultural Regions
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. , small farms produce about one-third of the world's food, but large farms are prevalent. The largest 1% of farms in the world are greater than and operate more than 70% of the world's farmland. Nearly 40% of agricultural land is found on farms larger than . However, five of every six farms in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trumao
Trumao is the name of a soil of the Andosol order found in southern and central Chile. Trumaos are formed from young volcanic ash, by volcanic ash redeposited by aeolian processes or by volcanic ash mobilized as alluvium. Trumaos are characterized by containing the following minerals: allophane, imogolite plus a series of paracrystalline and non-crystalline clays. These soils have high porosity and low bulk density. A more dry and a more humid variety of trumaos exists. The dry variety is known simply as trumao while the humid variety is known as trumao húmedo. In terms of latitude trumaos can be found in the Andes from 33° S to 43° S, in the Central Valley from 38° S to 43° S and in the eastern slopes of the Chilean Coast Range from 39° S to 43° S.

Soil Horizon
A soil horizon is a layer parallel to the soil surface whose physical, chemical and biological characteristics differ from the layers above and beneath. Horizons are defined in many cases by obvious physical features, mainly colour and texture. These may be described both in absolute terms (particle size distribution for texture, for instance) and in terms relative to the surrounding material, i.e. 'coarser' or 'sandier' than the horizons above and below. The identified horizons are indicated with symbols, which are mostly used in a hierarchical way. Master horizons (main horizons) are indicated by capital letters. Suffixes, in form of lowercase letters and figures, further differentiate the master horizons. There are many different systems of horizon symbols in the world. No one system is more correct—as artificial constructs, their utility lies in their ability to accurately describe local conditions in a consistent manner. Due to the different definitions of the horizon sym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
