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, ...

Kippax Centre, Australian Capital Territory
Kippax Fair is a shopping centre in the western Canberra suburb of Holt, Australian Capital Territory, Australia. Named after cricketer Alan Kippax, it serves the West Belconnen region, and is anchored by a Woolworths Supermarket, an Aldi discount supermarket, and other stores, restaurants, cafeterias, bars, and community services. History In 1974, as the region of West Belconnen was slowly emerging, an approach was made by the ACT Government to build a sizeable shopping centre on a large plot of land neighbouring the Parkwood industrial estate. Its original design was to encompass one indoor shopping complex and two outdoor strip malls A strip mall, strip center or strip plaza is a type of shopping center common in North America where the stores are arranged in a row, with a sidewalk in front. Strip malls are typically developed as a unit and have large parking lots in front. ..., now housing the majority of the centre's north-eastern wing. It opened in March 1976. In ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

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] |
Rhyodacite
Rhyodacite is a volcanic rock intermediate in composition between dacite and rhyolite. It is the extrusive equivalent of those plutonic rocks that are intermediate in composition between monzogranite and granodiorite. Rhyodacites form from rapid cooling of lava relatively rich in silica and low in alkali metal oxides. Description Under IUGS guidelines, rhyodacites are not formally defined in either the QAPF classification, used to classify igneous rocks by their mineral content, or the TAS classification, used to classify volcanic rocks chemically. However, the IUGS allows the use of the term to describe rocks close to the boundary between the rhyolite and dacite fields in each classification scheme. Rhyodacite then describes a fine-grained igneous rock containing between 20% and 60% quartz and in which plagioclase makes up about two-thirds of the total feldspar content. Such a rock will contain between 69% and 72% silica by weight. The U.S. Geological Survey defines rhyodacite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuff
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous (for example, ''tuffaceous sandstone''). Tuff composed of sandy volcanic material can be referred to as volcanic sandstone. Tuff is a relatively soft rock, so it has been used for construction since ancient times. Because it is common in Italy, the Romans used it often for construction. The Rapa Nui people used it to make most of the ''moai'' statues on Easter Island. Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms. Tuff is often erroneously called tufa in guidebooks and in television programmes. Volcanic ash The material that is expelled in a volcanic ...

Rhyolite
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent to granite. Rhyolitic magma is extremely viscous, due to its high silica content. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been extensively used for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil amendment. Description Rhyolite i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silurian
The Silurian ( ) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized. A significant evolutionary milestone during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
