Belconnen
Belconnen () is a Lands administrative divisions of Australia#Australian Capital Territory, district in the Australian Capital Territory in Australia. The district is subdivided into 27 divisions (suburbs), sections and blocks. As at the , the district had a population of people; and was the most populous district within the Australian Capital Territory (ACT). Belconnen is situated approximately to the north-west of the City, Australian Capital Territory, central business district of Canberra, and surrounds an artificially created, ornamental lake, Lake Ginninderra. Lake Ginninderra was made possible by building a dam at an elbow of Ginninderra Creek. Exiting the lake, via a simple overflow, Ginninderra Creek continues, and runs north-west to its confluence with the Murrumbidgee River just beyond the north-western ACT border.

Elections In Australia
Elections in Australia take place periodically to elect the legislature of the Commonwealth of Australia, as well as for each Australian states and territories, 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 Parliament of Australia, Australian Parliament are held under the Electoral system of Australia, federal electoral system, which is uniform throughout the country, and the elections for state and territory Parliaments are held under the electoral systems of the Australian states and territories, electoral system of each state and territory. An election day is always a Saturday, but early voting is allowed in the lead-up to it. 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. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhyolite
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture (geology), texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained matrix (geology), groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent of granite. Its high silica content makes rhyolitic magma extremely viscosity, viscous. 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 used extensively 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 ... [...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 tholeiitic and calc-alkaline magma series. Etymology The word ''dacite'' comes from Dacia, a province of the Roman Empire which lay between the Danube River and Carpathian Mountains (now modern Romania and Moldova) where the rock was first described. The term ''dacite'' was used for the first time in the scientific literature in the book ''Geologie Siebenbürgens'' (''The Geology of Transylvania'') by Austrian geologists Franz Ritter von Hauer and Guido Stache. Dacite was originally defined as a new rock type to separate calc-alkaline ... [...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] |
Silurian
The Silurian ( ) is a geologic period and system spanning 23.5 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 third and shortest period of the Paleozoic Era, and the third of twelve periods of the Phanerozoic Eon. 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) ...

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, Canberra, Legislative Assembly Building on Civic Square, close to City, Australian Capital Territory, the centre of the city of Canberra. Unlike the legislatures of the other mainland states and territories, the Assembly also has the functions of a local council; the city of Canberra has no other local government. It replaced the Australian Capital Territory House of Assembly, House of Assembly when the ACT was granted self-government in 1986. Voters had previously rejected self government in a 1978 plebiscite. Structure and Membership The Legislative Assembly has 25 members, elected from five electorates ― Brindabella electorate, Brindabella, Ginninderra electorate, Ginninderra, Kurrajong electorate, Kurrajong, Murrumbidgee electorate, Murrumbidgee ...

House Of Representatives (Australia)
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 set out 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 alongside the whole Senate. Elections for members of the House of Representatives have always been held in conjunction with those for the Senate since the 1970s. 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". Under the conventions of the Westminster system, the government of the day and the prime minister must achieve and maintain the confidence of this House ...
