Lawson, Australian Capital Territory
Lawson (postcode: 2617) is a suburb in the Belconnen district of Canberra, located within the Australian Capital Territory, Australia. The suburb is surrounded by Baldwin Drive, Gundaroo Drive and Ginninderra Drive. It lies next to the suburbs of McKellar, Giralang, Kaleen, Bruce and Belconnen. Two intersections were built in 2012 that lead into the suburb's grasslands, prepared for future development on the suburb, one leading off Ginninderra Drive, and another off Baldwin Drive. However, neither intersection continued on further than a few metres. Development was delayed by about two years by Commonwealth environmental clearance processes due to the presence of golden sun moth and native grassland. Construction of roads have commenced and the first residential land was sold on 3 December 2013. The suburb derives its name from Henry Lawson, short story writer and poet. The streets in Lawson are named after aspects of Australia appearing in his writing. A bicycle path runs alo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belconnen
The District of Belconnen () is one of the original eighteen districts of the Australian Capital Territory (ACT), used in land administration. The district is subdivided into 27 divisions (suburbs), sections and blocks. The district of Belconnen is largely composed of Canberra suburbs. 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 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.

Synemon Plana
''Synemon plana'', commonly known as the golden sun moth, is a Diurnal animal, diurnal moth native to Australia and throughout its range, it is currently classified as vulnerable under the ''Environment Protection and Biodiversity Conservation Act 1999.'' Taxonomy A description of the species was published in 1854 (Lepidoptera: Castniidae), as a medium-sized (wingspan 31–34 mm), day-flying moth species. Up until recently, the species had been listed as Critically Endangered, critically endangered, attracting the status of a flagship species towards the conservation of natural temperate grassland. Description The golden sun moth is a medium sized, day-flying moth with distinct green eyes and clubbed antenna (biology), antennae. The antennae are a notable feature of ''Synemon plana''; as most other moths have brushy antennae. Listed as critically endangered under the EPBC Act 1999, it is synonymous with ''Rytidosperma'' species of grasses and is almost completely confined to g ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Greywacke
Greywacke or graywacke (German ''grauwacke'', signifying a grey, earthy rock) is a variety of sandstone generally characterized by its hardness, dark color, and poorly sorted angular grains of quartz, feldspar, and small rock fragments or lithic fragments set in a compact, clay-fine matrix. It is a texturally immature sedimentary rock generally found in Paleozoic strata. The larger grains can be sand- to gravel-sized, and matrix materials generally constitute more than 15% of the rock by volume. The term "greywacke" can be confusing, since it can refer to either the immature (rock fragment) aspect of the rock or its fine-grained (clay) component. The origin of greywacke was unknown until turbidity currents and turbidites were understood, since, according to the normal laws of sedimentation, gravel, sand and mud should not be laid down together. Geologists now attribute its formation to submarine avalanches or strong turbidity currents. These actions churn sediment and cause mi ...

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] |
Ordovician
The Ordovician ( ) is a geologic period and System (geology), system, the second of six periods of the Paleozoic Era (geology), Era. The Ordovician spans 41.6 million years from the end of the Cambrian Period million years ago (Mya) to the start of the Silurian Period Mya. The Ordovician, named after the Celtic Britons, Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same Rock (geology), rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed Stratum, strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official period of the Paleozoic Era by the International Union of Geological Sciences, Intern ...

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] |

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 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 Representative ...
