Ginninderra Electorate
The Ginninderra electorate is one of the five electorates for the unicameral 25-member Australian Capital Territory Legislative Assembly. It elects five members. History It was created in 1995, when the three-electorate, Hare-Clark electoral system was first introduced for the Australian Capital Territory (ACT). Prior to 1995, a multi-member single constituency existed for the whole of the ACT. The name "Ginninderra" is derived from an Aboriginal word meaning "sparkling like the stars". It is the name given to the creek that flows through the middle of Belconnen, which was dammed to form Lake Ginninderra, the lake on which the Belconnen Town Centre is sited. Location The Ginninderra electorate comprises the southern part of the district of Belconnen, including the suburbs of Aranda, Belconnen, Bruce, Charnwood, Cook, Dunlop, Evatt, Florey, Flynn, Fraser, Hawker, Higgins, Holt, Latham, Lawson, Macgregor, Macnamara, Macquarie, Melba, McKellar, Page, Scullin, Spence, ...

Opera
Opera is a form of theatre in which music is a fundamental component and dramatic roles are taken by singers. Such a "work" (the literal translation of the Italian word "opera") is typically a collaboration between a composer and a librettist and incorporates a number of the performing arts, such as acting, scenery, costume, and sometimes dance or ballet. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor. Although musical theatre is closely related to opera, the two are considered to be distinct from one another. Opera is a key part of the Western classical music tradition. Originally understood as an entirely sung piece, in contrast to a play with songs, opera has come to include numerous genres, including some that include spoken dialogue such as '' Singspiel'' and '' Opéra comique''. In traditional number opera, singers employ two styles of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adamellite
Quartz monzonite is an intrusive, felsic, igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars. It is typically a light colored phaneritic (coarse-grained) to porphyritic granitic rock. The plagioclase is typically intermediate to sodic in composition, andesine to oligoclase. Quartz is present in significant amounts. Biotite and/or hornblende constitute the dark minerals. Because of its coloring, it is often confused with granite, but whereas granite contains more than 20% quartz, quartz monzonite is only 5–20% quartz. Rock with less than five percent quartz is classified as monzonite. A rock with more alkali feldspar is a syenite whereas one with more plagioclase is a quartz diorite.Classification of Igneous Rocks The fine grained |
Andesite
Andesite () is a volcanic rock of intermediate composition. In a general sense, it is the intermediate type between silica-poor basalt and silica-rich rhyolite. It is fine-grained (aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende. Andesite is the extrusive equivalent of plutonic diorite. Characteristic of subduction zones, andesite represents the dominant rock type in island arcs. The average composition of the continental crust is andesitic. Along with basalts, andesites are a component of the Martian crust. The name ''andesite'' is derived from the Andes mountain range, where this rock type is found in abundance. It was first applied by Christian Leopold von Buch in 1826. Description Andesite is an aphanitic (fine-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspathoid by volume, with at least 65% of the fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dacite
Dacite () is a volcanic rock formed by rapid solidification of lava that is high in silica and low in alkali metal oxides. It has a fine-grained (aphanitic) to porphyritic texture and is intermediate in composition between andesite and rhyolite. It is composed predominantly of plagioclase feldspar and quartz. Dacite is relatively common, occurring in many tectonic settings. It is associated with andesite and rhyolite as part of the subalkaline volcanic rock, subalkaline tholeiite, tholeiitic and calc-alkaline magma series. Composition Dacite consists mostly of plagioclase feldspar and quartz with biotite, hornblende, and pyroxene (augite or enstatite). The quartz appears as rounded, corroded phenocrysts, or as an element of the ground-mass. The plagioclase in dacite ranges from oligoclase to andesine and labradorite. Sanidine occurs, although in small proportions, in some dacites, and when abundant gives rise to rocks that form rhyodacite, transitions to the rhyolites. The rel ...

Feldspar
Feldspars are a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the ''plagioclase'' (sodium-calcium) feldspars and the ''alkali'' (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight. Feldspars crystalize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks. Compositions The feldspar group of minerals consists of tectosilicates, silicate minerals in which silicon ions are linked by shared oxygen ions to form a three-dimensional network. Compositions of major elements in common feldspars can be expressed in terms of three endmembers: * potassium feldspar (K-spar) ...

Porphyry (geology)
Porphyry ( ) is a textural term for an igneous rock consisting of coarse-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate-rich, generally aphanitic matrix or groundmass. The larger crystals are called phenocrysts. In its non-geologic, traditional use, the term ''porphyry'' refers to the purple-red form of this stone, valued for its appearance. The term ''porphyry'' is from the Ancient Greek (), meaning "purple". Purple was the color of royalty, and the "imperial porphyry" was a deep purple igneous rock with large crystals of plagioclase. Some authors claimed the rock was the hardest known in antiquity. Thus, "imperial"-grade porphyry was prized for monuments and building projects in Imperial Rome and thereafter. Subsequently, the name was given to any igneous rocks with large crystals. The adjective ''porphyritic'' now refers to a certain texture of igneous rock regardless of its chemical and mineralogical composition. Its chief characteris ...

Australian Capital Territory Legislative Assembly
The Legislative Assembly for the Australian Capital Territory (known in short as the ACT Legislative Assembly) is the unicameral legislature of the Australian Capital Territory (ACT). It sits in the Legislative Assembly Building on Civic Square, close to the centre of the city of Canberra. Creation The Assembly was created by four acts of the Commonwealth Parliament in 1988, including the Australian Capital Territory (Self-Government) Act 1988. The first election was held on 4 March 1989 and the assembly first sat on 11 May that year. Until this point, the ACT had been directly administered by the Commonwealth Government. It replaced the House of Assembly (also known for a period as the Legislative Assembly), which existed from 1976 to 1986, but had no executive power, with a principal function of advising the Commonwealth on matters relating to the Territory. Membership Since October 2016, the Legislative Assembly has 25 members elected from five electorates, Brindabell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australian House Of Representatives
The House of Representatives is the lower house of the bicameral Parliament of Australia, the upper house being the Senate. Its composition and powers are established in Chapter I of the Constitution of Australia. The term of members of the House of Representatives is a maximum of three years from the date of the first sitting of the House, but on only one occasion since Federation has the maximum term been reached. The House is almost always dissolved earlier, usually alone but sometimes in a double dissolution of both Houses. Elections for members of the House of Representatives are often held in conjunction with those for the Senate. A member of the House may be referred to as a "Member of Parliament" ("MP" or "Member"), while a member of the Senate is usually referred to as a "Senator". The government of the day and by extension the Prime Minister must achieve and maintain the confidence of this House in order to gain and remain in power. The House of Representatives c ...

Elections In Australia
Elections in Australia take place periodically to elect the legislature of the Commonwealth of Australia, as well as for each Australian state and territory and for local government councils. Elections in all jurisdictions follow similar principles, although there are minor variations between them. The elections for the Australian Parliament are held under the federal electoral system, which is uniform throughout the country, and the elections for state and territory Parliaments are held under the electoral system of each state and territory. Part IV of Chapter 1 of the Australian Constitution briefly deals with eligibility for voting and election to the federal Australian Parliament. It does not prescribe how elections should be conducted. Election campaigns and associated political advertisements are subject to some regulation. Public funding of political parties and party registration was introduced in 1983. Voting for the federal and each state and territory parliament is ...

Women's Tennis Association
The Women's Tennis Association (WTA) is the principal organizing body of women's professional tennis. It governs the WTA Tour which is the worldwide professional tennis tour for women and was founded to create a better future for women's tennis. The WTA's corporate headquarters is in St. Petersburg, Florida, with its European headquarters in London and its Asia-Pacific headquarters in Beijing. The Women's Tennis Association was founded in June 1973 by Billie Jean King, and traces its origins to the inaugural Virginia Slims tournament, arranged by Gladys Heldman, sponsored by Joe Cullman, CEO of Philip Morris, and held on 23 September 1970 at the Houston Racquet Club in Houston, Texas. Rosie Casals won this first event. When the Women's Tennis Association was founded, Billie Jean King was one of nine players that comprised the WTA, also referred to as the Original 9, that included Julie Heldman, Valerie Ziegenfuss, Judy Dalton, Kristy Pigeon, Peaches Bartkowicz, Kerry Mel ...
