Amaroo, Australian Capital Territory
Amaroo () is a suburb in the Canberra, Australia district of Gungahlin and was gazetted on 18 October 1991. Amaroo means 'a beautiful place' in Nyoongar. Place names in Amaroo such as Shoalhaven Avenue are named after Australian rivers and lakes. Amaroo is adjacent to the suburbs of Ngunnawal, Gungahlin, Moncrieff, Forde, Bonner and Jacka. The suburb is bounded by Mirrabei Drive and Horse Park Drive and Gundaroo Drive. The suburb is located approximately 1 km from the Gungahlin Town Centre and 15 km from the centre of Canberra. History Although the suburb of Amaroo is newly established, the history of the land upon which the suburb is situated stretches back at least one hundred and fifty years. Amongst the historic remnants from Amaroo's colonial past is Crinigan's stone cottage located in Wanderer Court Amaroo. John and Maria (née Mansfield) Crinigan lived in a stone cottage at this site from about 1842 until 1863. John was a native of Westmeath, Ireland and ...

Gungahlin
The District of Gungahlin () is one of the original eighteen districts of the Australian Capital Territory used in land administration. The Gungahlin Region is one of fastest growing regions within Australia. The district is subdivided into divisions ( suburbs), sections and blocks. ''Gungahlin'' is an Aboriginal word meaning either "white man's house" or "little rocky hill". Gungahlin comprised sixteen suburbs, including several currently under construction and a further suburb planned. The town of Gungahlin was part of the original 1957 plan for future development in the ACT and in 1991 was officially launched as Canberra's fourth 'town' by the ACT Chief Minister. At the time, the population of Gungahlin was just 389 residents. At the , the population of the district was 87,682. Within the district is Canberra's northernmost town centre that is situated north of Canberra city centre. The town centre is one of five satellites of Canberra, seated in Woden, Tuggeranong, Wes ...

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 ...

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 ...

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] |

Ginninderra Creek
Ginninderra Creek, a partly perennial stream of the Murrumbidgee catchment within the Murray–Darling basin, is located in the Capital Country region spanning both the Australian Capital Territory and New South Wales, Australia. ''Ginninderra'' is derived from the Aboriginal word, meaning "sparkling" or "throwing little rays of light". The traditional custodians of the land surrounding Ginninderra Creek are the Aboriginal people of the Ngunnawal tribe. Course Ginninderra Creek rises on the northern border between the Australian Capital Territory (ACT) and New South Wales (NSW), sourced from the Spring Range, located north-east of Hall. The creek flows generally south-west across the Ginninderra Plain, through the Gungahlin and Belconnen regions in Canberra, and then heads west crossing the western border between the ACT and flowing into NSW, towards its confluence with the Murrumbidgee River. The creek descends over its course. Ginninderra Creek is impounded by Gungah ... [...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.
