Kallur Archaeological Site
Kallur is an archaeological site and village located in the Manvi taluk of Raichur district in the state of Karnataka, India.Amalananda Ghosh (1990), p197 It belongs to Gulbarga division. The site came into prominence with the discovery of antennae swords in the 1930s, which was the first instance of the Copper Hoard culture being discovered in South India. The earliest finding here has been dated to the Neolithic period. Etymology The word ''Kallur'' is formed from two Kannada words: ''kallu'' which means "stone" and ''ooru'' which means "town". The number of granite hillocks that surround Kallur, may have given the place its name. Some of the hillocks that are present here are ''Yammigudda'', ''Pirbannur'', ''Agsargudda'', ''Kampangudda'' and ''Polannagudda''. Excavation history The site was first excavated in 1939–40 by M. Khwaja Ahmed of the Archaeological Department of Hyderabad state. It was later explored by F. Raymond Allchin in 1952.F. R. Allchin (1979), p113 Fi ...

States And Territories Of India
India is a federal union comprising 28 states and 8 union territories, with a total of 36 entities. The states and union territories are further subdivided into districts and smaller administrative divisions. History Pre-independence The Indian subcontinent has been ruled by many different ethnic groups throughout its history, each instituting their own policies of administrative division in the region. The British Raj mostly retained the administrative structure of the preceding Mughal Empire. India was divided into provinces (also called Presidencies), directly governed by the British, and princely states, which were nominally controlled by a local prince or raja loyal to the British Empire, which held ''de facto'' sovereignty ( suzerainty) over the princely states. 1947–1950 Between 1947 and 1950 the territories of the princely states were politically integrated into the Indian union. Most were merged into existing provinces; others were organised into ... [...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 ...

Smelting
Smelting is a process of applying heat to ore, to extract a base metal. It is a form of extractive metallurgy. It is used to extract many metals from their ores, including silver, iron, copper, and other base metals. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind. The reducing agent is commonly a fossil fuel source of carbon, such as coke—or, in earlier times, charcoal. The oxygen in the ore binds to carbon at high temperatures due to the lower potential energy of the bonds in carbon dioxide (). Smelting most prominently takes place in a blast furnace to produce pig iron, which is converted into steel. The carbon source acts as a chemical reactant to remove oxygen from the ore, yielding the purified metal element as a product. The carbon source is oxidized in two stages. First, the carbon (C) combusts with oxygen (O2) in the air to produce carbon monoxide (CO). Second, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartzite
Quartzite is a hard, non- foliated metamorphic rock which was originally pure quartz sandstone.Essentials of Geology, 3rd Edition, Stephen Marshak, p 182 Sandstone is converted into quartzite through heating and pressure usually related to tectonic compression within orogenic belts. Pure quartzite is usually white to grey, though quartzites often occur in various shades of pink and red due to varying amounts of hematite. Other colors, such as yellow, green, blue and orange, are due to other minerals. The term ''quartzite'' is also sometimes used for very hard but unmetamorphosed sandstones that are composed of quartz grains thoroughly cemented with additional quartz. Such sedimentary rock has come to be described as orthoquartzite to distinguish it from metamorphic quartzite, which is sometimes called metaquartzite to emphasize its metamorphic origins. Quartzite is very resistant to chemical weathering and often forms ridges and resistant hilltops. The nearly pure silica conte ...

Iron Ore
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (, 72.4% Fe), hematite (, 69.9% Fe), goethite (, 62.9% Fe), limonite (, 55% Fe) or siderite (, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. In 2011 the ''Financial Times'' quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is "more integral to the global economy than any other commodity, except perhaps oil". Sources Metallic iron is virtually unknown on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalcedony
Chalcedony ( , or ) is a cryptocrystalline form of silica, composed of very fine intergrowths of quartz and moganite. These are both silica minerals, but they differ in that quartz has a trigonal crystal structure, while moganite is monoclinic. Chalcedony's standard chemical structure (based on the chemical structure of quartz) is SiO2 (silicon dioxide). Chalcedony has a waxy luster, and may be semitransparent or translucent. It can assume a wide range of colors, but those most commonly seen are white to gray, grayish-blue or a shade of brown ranging from pale to nearly black. The color of chalcedony sold commercially is often enhanced by dyeing or heating. The name ''chalcedony'' comes from the Latin ''chalcedonius'' (alternatively spelled ''calchedonius'') and is probably derived from the town of Chalcedon in Turkey. The name appears in Pliny the Elder's ''Naturalis Historia'' as a term for a translucent kind of jaspis. Another reference to a gem by the name of ''khalkedon'' ...

Jasper
Jasper, an aggregate of microgranular quartz and/or cryptocrystalline chalcedony and other mineral phases,Kostov, R. I. 2010. Review on the mineralogical systematics of jasper and related rocks. – Archaeometry Workshop, 7, 3, 209-213PDF/ref> is an opaque, impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron(III) inclusions. Jasper breaks with a smooth surface and is used for ornamentation or as a gemstone. It can be highly polished and is used for items such as vases, seals, and snuff boxes. The specific gravity of jasper is typically 2.5 to 2.9. Jaspillite is a banded-iron-formation rock that often has distinctive bands of jasper. Etymology and history The name means "spotted or speckled stone," and is derived via Old French ''jaspre'' (variant of Anglo-Norman ''jaspe'') and Latin ''iaspidem'' (nom. ''iaspis'') from Greek ἴασπις ''iaspis'' (feminine noun), from an Afroasiatic language (cf. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chert
Chert () is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). Chert is characteristically of biological origin, but may also occur inorganically as a precipitation (chemistry), chemical precipitate or a diagenesis, diagenetic replacement, as in petrified wood. Chert is typically composed of the petrified remains of siliceous ooze, the biogenic sediment that covers large areas of the deep ocean floor, and which contains the silicon skeletal remains of diatoms, Dictyochales, silicoflagellates, and radiolarians. Precambrian cherts are notable for the presence of fossil cyanobacteria. In addition to Micropaleontology, microfossils, chert occasionally contains macrofossils. However, some chert is devoid of any fossils. Chert varies greatly in color (from white to black), but most often manifests as gray, brown, grayish brown and light green to rusty redW.L.

Russet (color)
Russet is a dark brown color with a reddish-orange tinge. As a tertiary color, russet is an equal mix of orange and purple pigments. The first recorded use of russet as a color name in English was in 1562. The source of this color is ''The ISCC-NBS Method of Designating Colors and a Dictionary of Color Names'' (1955) used by stamp collectors to identify the colors of stamps. However, it is widely considered hard to standardize, and the same vary name could be applied to various tones; ''russet'' often has no more specific meaning than ''ruddy'' or ''reddish''. The name of this color derives from russet, a coarse cloth made of wool and dyed with woad and madder to give it a subdued grey or reddish-brown shade. By the statute of 1363, poor English people were required to wear russet. Russet, a color of autumn, is often associated with sorrow or grave seriousness. Anticipating a lifetime of regret, Shakespeare's character Biron says in ''Love's Labour's Lost'', Act V, Scene 1: "He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Koban Culture
The Koban culture (c. 1100 to 400 BC) is a late Bronze Age and Iron Age culture of the northern and central Caucasus. It is preceded by the Colchian culture of the western Caucasus and the Kharachoi culture further east. It is named after the village of Koban, Northern Ossetia, where in 1869 battle-axes, daggers, decorative items and other objects were discovered in a kurgan. Later, further sites were uncovered in the central Caucasus. Geographical extent The culture flourished on both sides of the Great Caucasus Range, and extended into the areas of Ingushetia, Kabardino-Balkaria, Karachay-Cherkessia, and North Ossetia-Alania, and South Ossetia. It also reached the high north-western regions of Georgia such as Racha and Svaneti. Some areas of Northeast Caucasus also had Koban settlements, in particular the modern Ingushetia and the western regions of Chechnya.P.
