Gungahlin
Gungahlin () is a Lands administrative divisions of Australia#Australian Capital Territory, district in the Australian Capital Territory, one of the fastest growing regions in Australia. The district is subdivided into suburbs, sections and blocks. ''Gungahlin'' is an Australian Aboriginal languages, Aboriginal word meaning either "white man's house" or "little rocky hill". Gungahlin comprised sixteen suburbs, including several under construction and a further suburb planned. The town of Gungahlin was part of the original 1957 plan for development in the ACT and in 1991 was officially launched as the 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.

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 Geology of Mars, 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) to porphyritic (coarse-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspa ... [...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] |
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.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 distinguished without a micros ... [...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 mineral, clay minerals (hydrous aluminium phyllosilicates, e.g., Kaolinite, kaolin, aluminium, Al2Silicon, Si2Oxygen, O5(hydroxide, 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 (Lamination (geology), laminae) less than one centimeter in thickness. This property is called ''Fissility (geology), 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 narrower 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 in ...

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) ...

Yerrabi Pond Amaroo
The Yerrabi electorate is one of the five electorates for the unicameral 25-member Australian Capital Territory Legislative Assembly. It elected five members at the 2016 ACT election. History Yerrabi was created in 2016, when the five-electorate, 25-member Hare-Clark electoral system was first introduced for the Australian Capital Territory (ACT) Legislative Assembly, replacing the previous three-electorate, 17-member system. The word "Yerrabi" is derived from a word in the Ngunnawal language meaning "go", "walk" or "to leave", and shares its name with Yerrabi Pond in Amaroo which is one of the main water features in the Gungahlin district. Location The Yerrabi electorate comprises the entire district of Gungahlin, including the suburbs of Amaroo, Bonner, Casey, Crace, Forde, Franklin, Gungahlin, Harrison, Jacka, Moncrieff, Ngunnawal, Nicholls, Palmerston, Taylor, Throsby, the Belconnen district suburbs of Giralang and Kaleen and the Township of Hall.

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 Gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
