Chavín De Huántar
Chavín de Huántar is an archaeological site in Peru, containing ruins and artifacts constructed as early as 1200 BC, and occupied until around 400–500 BC by the Chavín, a major pre-Inca culture. The site is located in the Ancash Region, north of Lima, at an elevation of , east of the Cordillera Blanca at the start of the Conchucos Valley. Chavín de Huántar has been designated as a UNESCO World Heritage Site. Some of the Chavín relics from this archaeological site are on display in the Museo de la Nación in Lima and the Museo Nacional de Chavín in Chavín itself. Occupation at Chavín de Huántar has been carbon-dated to at least 3000 BC, with ceremonial center activity occurring primarily toward the end of the second millennium, and through the middle of the first millennium BC. While the fairly large population was based on an agricultural economy, the city's location at the headwaters of the Marañón River, between the coast and the jungle, made it an ideal loca ...

Ancash Region
Ancash ( qu, Anqash; es, Áncash ) is a department and region in northern Peru. It is bordered by the departments of La Libertad on the north, Huánuco and Pasco on the east, Lima on the south, and the Pacific Ocean on the west. Its capital is the city of Huaraz, and its largest city and port is Chimbote. The name of the region originates from the Quechua word ('light, of little weight'), from ('blue') or from ('eagle'). Geography Ancash is a land of contrasts: it features two great longitudinal valleys, which combine the mountain characteristics of the Callejón de Huaylas (Alley of Huaylas) with the sylvan ones of the Alto Marañón. Kilometres of sandy beaches and the blue waters of the Pacific. The territory of the coast, high plateaux and Andean '' punas'' of the department are flat, while the rest of the territory, in the Andes, is very rough. In the west, there are slopes with strong declivity form narrow canyons with abrupt and deserted sides. The rough territor ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Textiles
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different fabric types, etc. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to bulletproof jackets, spacesuits, and doctor's gowns. Textiles are divided into two groups: Domestic purposes onsumer textilesand technical textiles. In consumer textiles, aesthetics and comfort are the most important factors, but in technical textiles, functional properties are the priority. Geotextiles, industrial textiles, medical textiles, and many other areas are examples of technical textiles, whereas clothing and ...

Spondylus
''Spondylus'' is a genus of bivalve molluscs, the only genus in the family (biology), family Spondylidae.MolluscaBase (2019). MolluscaBase. Spondylus Linnaeus, 1758. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=138518 on 2019-03-04 They are known in English as spiny oysters or thorny oysters (though they are not, in fact, true oysters). Description The many species of ''Spondylus'' vary considerably in appearance. They are grouped in the same superfamily as the scallops. They are not closely related to true oysters (family Ostreidae); however, they do share some habits such as cementing themselves to rocks rather than attaching themselves by a byssus. The two halves of their shells are joined with a ball-and-socket type of hinge, rather than with a toothed hinge as is more common in other bivalves. They also still retain vestigial anterior and posterior ''auricles'' ("ears", triangular shell flaps) along the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strombus
''Strombus'' is a genus of medium to large sea snails, marine gastropod molluscs in the family Strombidae, which comprises the true conchs and their immediate relatives. The genus ''Strombus'' was named by Swedish Naturalist Carl Linnaeus in 1758. Around 50 living species were recognized, which vary in size from fairly small to very large. Six species live in the greater Caribbean region, including the queen conch, ''Strombus gigas'' (now usually known as ''Eustrombus gigas'' or ''Lobatus gigas''), and the West Indian fighting conch, '' Strombus pugilis''. However, since 2006, many species have been assigned to discrete genera. These new genera are, however, not yet found in most textbooks and collector's guides. Worldwide, several of the larger species are economically important as food sources; these include the endangered queen conch, which very rarely also produces a pink, gem-quality pearl. In the geological past, a much larger number of species of ''Strombus'' existed. Fos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lanzón
The Lanzón is a granite stela that is associated with the Chavín culture. It is located in the Old Temple of Chavin de Huantar which rests in the central highlands of Peru. The Chavín religion was the first major religious and cultural movement in the Andes mountains, flourishing between 900 and 200 BCE. The Lanzón itself was erected during the Early Horizon period of Andean art circa 500 BCE and takes its name from the Spanish word for "lance," an allusion to the shape of the sculpture. The name is deceiving, as its form more closely resembles a highland plow which would have been used for agricultural purposes at the time. It is suspected because of this that the deity depicted is linked to agrarian worship. Geographic location and significance The Lanzón rests in the heart of Chavín de Huantar. This site at the time was on one of the few passes between the mountainous region of the coast and the dense Amazon. Due to the difficulty of the geography, one must have used ...

Caiman
A caiman (also cayman as a variant spelling) is an alligatorid belonging to the subfamily Caimaninae, one of two primary lineages within the Alligatoridae family, the other being alligators. Caimans inhabit Mexico, Central and South America from marshes and swamps to mangrove rivers and lakes. They have scaly skin and live a fairly nocturnal existence. They are relatively small-sized crocodilians with an average maximum weight of depending on species, with the exception of the black caiman (''Melanosuchus niger''), which can grow more than in length and weigh in excess of 1,000 kg (2,200 Ib). The black caiman is the largest caiman species in the world and is found in the slow-moving rivers and lakes that surround the Amazon basin. The smallest species is the Cuvier's dwarf caiman (''Paleosuchus palpebrosus''), which grows to long. There are six different species of caiman found throughout the watery jungle habitats of Central and Southern America. The average length for most ...

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 rainfo ...

Course (architecture)
A course is a layer of the same unit running horizontally in a wall. It can also be defined as a continuous row of any masonry unit such as bricks, concrete masonry units (CMU), stone, shingles, tiles, etc. Coursed masonry construction arranges units in regular courses. Oppositely, coursed rubble masonry construction uses random uncut units, infilled with mortar or smaller stones. If a course is the horizontal arrangement, then a wythe is a continuous vertical section of masonry one unit in thickness. A wythe may be independent of, or interlocked with, the adjoining wythe(s). A single wythe of brick that is not structural in nature is referred to as a masonry veneer. A standard 8-inch CMU block is exactly equal to three courses of brick. A bond (or bonding) pattern) is the arrangement of several courses of brickwork. The corners of a masonry wall are built first, then the spaces between them are filled by the remaining courses. Orientations Masonry coursing can be arrang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diatomite
Diatomaceous earth (), diatomite (), or kieselgur/kieselguhr is a naturally occurring, soft, siliceous sedimentary rock that can be crumbled into a fine white to off-white powder. It has a particle size ranging from more than 3 μm to less than 1 mm, but typically 10 to 200 μm. Depending on the granularity, this powder can have an abrasive feel, similar to pumice powder, and has a low density as a result of its high porosity. The typical chemical composition of oven-dried diatomaceous earth is 80–90% silica, with 2–4% alumina (attributed mostly to clay minerals), and 0.5–2% iron oxide. Diatomaceous earth consists of the fossilized remains of diatoms, a type of hard-shelled microalgae. It is used as a filtration aid, mild abrasive in products including metal polishes and toothpaste, mechanical insecticide, absorbent for liquids, matting agent for coatings, reinforcing filler in plastics and rubber, anti-block in plastic films, porous support for chemic ...
