Limay River
The Limay River is an important river in the northwestern Argentine Patagonia (the region of Comahue). It originates at the eastern end of the Nahuel Huapi Lake and flows in a meandering path for about , collecting the waters of several tributaries, such as the Traful River, the Pichileufú and the Collón Curá. It then meets the Neuquén River and together they become the Río Negro. At this confluence lies the city of Neuquén. The river serves as natural border between the provinces of Río Negro and Neuquén. Its deep waters are clear, and carry a large flow, on average. Its drainage basin has an area of and includes almost all the rivers and streams of the Atlantic basin in the region, as well as an extensive network of lakes. The waters of the Limay are used to generate hydroelectricity at the five dams built on its course: Alicurá, Piedra del Águila, Pichi Picún Leufú, El Chocón, and Arroyito; together with the Cerros Colorados Complex on the Neuquén River ...

General Julio Argentino Roca
Alejo Julio Argentino Roca Paz (July 17, 1843 – October 19, 1914) was an army general and statesman who served as President of Argentina from 1880 to 1886 and from 1898 to 1904. Roca is the most important representative of the Generation of '80 and is known for directing the Conquest of the Desert, a series of military campaigns against the indigenous peoples of Patagonia sometimes considered a genocide. During his two terms as president, many important changes occurred, particularly major infrastructure projects of railroads and port facilities; increased foreign investment, along with immigration from Europe; large-scale immigration from southern Europe; expansion of the agricultural and pastoral sectors of the economy; and laicizing legislation strengthening state power. Roca's main foreign policy concern was to set the limits with Chile, which had never been determined with precision. In 1881 Argentina gained territory by treaty with Chile. Upbringing and early ...

Conquest Of The Desert
The Conquest of the Desert ( es, Conquista del desierto) was an Argentine military campaign directed mainly by General Julio Argentino Roca in the 1870s with the intention of establishing dominance over the Patagonian Desert, inhabited primarily by indigenous peoples. The Conquest of the Desert extended Argentine territories into Patagonia and ended Chilean expansion in the region. Argentine troops killed more than 1,000 Mapuche, displaced over 15,000 more from their traditional lands and enslaved a portion of the remaining natives. Settlers of European descent moved in and developed the lands through irrigation for agriculture, turning the territory into a breadbasket that contributed to the emergence of Argentina as an agricultural superpower in the early 20th century.''The Argentine Military and the Boundary Dispute With Chile, 1870-1902,'' George V. Rauch, p. 47, Greenwood Publishing Group, 1999 The conquest was paralleled by a similar campaign in Chile called the Occupati ...

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limonite
Limonite () is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)·H2O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and has been mined for the production of iron since at least 2500 BP. Names Limonite is named for the Greek word λειμών (/leː.mɔ̌ːn/), meaning "wet meadow", or λίμνη (/lím.nɛː/), meaning “marshy lake” as an allusion to its occurrence as '' bog iron ore'' in meadows and marshes. In its brown form it is sometimes called brown hematite or brown iron ore. Characteristics Limonite is relatively dense with a specific gravity varying from 2.7 to 4.3.Northrop, Stuart A.

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pebble
A pebble is a clast of rock with a particle size of based on the Udden-Wentworth scale of sedimentology. Pebbles are generally considered larger than granules ( in diameter) and smaller than cobbles ( in diameter). A rock made predominantly of pebbles is termed a conglomerate. Pebble tools are among the earliest known man-made artifacts, dating from the Palaeolithic period of human history. A beach composed chiefly of surface pebbles is commonly termed a shingle beach. This type of beach has armoring characteristics with respect to wave erosion, as well as ecological niches that provide habitat for animals and plants. Inshore banks of shingle (large quantities of pebbles) exist in some locations, such as the entrance to the River Ore, England, where the moving banks of shingle give notable navigational challenges. Pebbles come in various colors and textures and can have streaks, known as veins, of quartz or other minerals. Pebbles are mostly smooth but, dependent on ...

Gravel
Gravel is a loose aggregation of rock fragments. Gravel occurs naturally throughout the world as a result of sedimentary and erosive geologic processes; it is also produced in large quantities commercially as crushed stone. Gravel is classified by particle size range and includes size classes from granule- to boulder-sized fragments. In the Udden-Wentworth scale gravel is categorized into granular gravel () and pebble gravel (). ISO 14688 grades gravels as fine, medium, and coarse, with ranges 2–6.3 mm to 20–63 mm. One cubic metre of gravel typically weighs about 1,800 kg (or a cubic yard weighs about 3,000 lb). Gravel is an important commercial product, with a number of applications. Almost half of all gravel production is used as aggregate for concrete. Much of the rest is used for road construction, either in the road base or as the road surface (with or without asphalt or other binders.) Naturally occurring porous gravel deposits have a ...

Sand
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand, for example, aragonite, which has mostly been created, over the past 500million years, by various forms of life, like coral and shellfish. For example, it is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean. Somewhat more rarely, sand may be composed of calciu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
