Pialligo, Australian Capital Territory
Pialligo ( postcode: 2609) () is a rural suburb of Canberra, Australian Capital Territory, Australia. The name ''Pialligo'' has been used for the area since at least 1820, and is probably of Aboriginal origin. It was also the name for the parish in the area. Streets in Pialligo are named with Aboriginal words. Beltana Road in Pialligo is home to many of Canberra's nurseries. Canberra Airport is located adjacent to Pialligo across Pialligo Avenue. Geology Quaternary alluvium covers the main western part of Pialligo. Calcareous shales from the Canberra Formation are deep underneath. The Woolshed Creek runs into the north end of Pialligo. This is a significant place, because in the bed of the creek the Rev W B Clarke first recognised Silurian fossils. These fossils were brachiopods, mostly ''Atrypa duntroonensis''. He discovered them around 1844 century and it was the first time that Silurian rocks were identified in Australia, and at the time were the oldest known rocks in Au ...

Majura (district)
The Majura District is a district of Canberra, with a population of 161 at the , excluding the suburb of Pialligo, which lies to the south of Canberra Airport. Apart from Pialligo, Majura District includes Canberra Airport and some farming but little residential development. Geography The Majura District is situated in the northeast corner of the ACT, to the east of the North Canberra district, Mount Ainslie and Mount Majura, north of the Molonglo River, west of Sutton Road and south of the New South Wales border. It is located in the Majura Valley, which is drained by Woolshed Creek. Majura is primarily covered by the Majura Field Firing Range, open grazing country and Canberra Airport. Majura Parkway, which was officially opened on 22 April 2016, and Majura Road run through it from the north to the south. Majura District is not generally zoned for residential development, partly because of the nearby airport. Its only significant settlement is Pialligo, which lies on its sou ...

Pialligo Parish, Murray
Pialligo Parish is a parish of Murray County, New South Wales, a cadastral unit for use on land titles. It is now a very tiny piece of land to the north-east of the Australian Capital Territory after most of the land in the parish was transferred to the ACT in 1911. It once included the area to the east of Mount Ainslie and the north of the Molonglo River, including Mount Majura and what is now Canberra Airport Canberra Airport is an international airport situated in the District of Majura, Australian Capital Territory serving Australia's capital city, Canberra, as well as the nearby city of Queanbeyan and regional areas of the Australian Capital Te ..., and the suburb of Pialligo.

Sequoiadendron Giganteum
''Sequoiadendron giganteum'' (giant sequoia; also known as giant redwood, Sierra redwood, Sierran redwood, California big tree, Wellingtonia or simply big treea nickname also used by John Muir) is the sole living species in the genus ''Sequoiadendron'', and one of three species of coniferous trees known as Sequoioideae, redwoods, classified in the family Cupressaceae in the subfamily Sequoioideae, together with ''Sequoia sempervirens'' (coast redwood) and ''Metasequoia glyptostroboides'' (dawn redwood). Giant sequoia specimens are the most massive trees on Earth. The common use of the name ''sequoia'' usually refers to ''Sequoiadendron giganteum'', which occurs naturally only in groves on the western slopes of the Sierra Nevada (U.S.), Sierra Nevada mountain range of California. The giant sequoia is listed as an endangered species by the IUCN, with fewer than 80,000 trees remaining. Since its last assessment as an endangered species in 2011, it was estimated that another 13–19% ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sequoia Sempervirens
''Sequoia sempervirens'' ()''Sunset Western Garden Book,'' 1995:606–607 is the sole living species of the genus '' Sequoia'' in the cypress family Cupressaceae (formerly treated in Taxodiaceae). Common names include coast redwood, coastal redwood, and California redwood. It is an evergreen, long-lived, monoecious tree living 1,200–2,200 years or more. This species includes the tallest living trees on Earth, reaching up to in height (without the roots) and up to in diameter at breast height. These trees are also among the oldest living things on Earth. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated along much of coastal California (excluding southern California where rainfall is not sufficient) and the southwestern corner of coastal Oregon within the United States. The name sequoia sometimes refers to the subfamily Sequoioideae, which includes ''S. sempervirens'' along with ''Sequoiadendron'' (gi ...

Walter Burley Griffin
Walter Burley Griffin (November 24, 1876February 11, 1937) was an American architect and landscape architect. He is known for designing Canberra, Australia's capital city and the New South Wales towns of Griffith, New South Wales, Griffith and Leeton, New South Wales, Leeton. He has been credited with the development of the L-shaped floor plan, the carport and an innovative use of reinforced concrete. Influenced by the Chicago-based Prairie School, Griffin developed a unique modern architecture, modern style. He worked in partnership with his wife Marion Mahony Griffin. In 28 years they designed over 350 buildings, landscape and urban-design projects as well as designing construction materials, interiors, furniture and other household items. Early life Griffin was born in 1876 in Maywood, Illinois, a suburb of Chicago. He was the eldest of the four children of George Walter Griffin, an insurance agent, and Estelle Burley Griffin. His family moved to Oak Park, Illinois, Oak Pa ... [...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] |
Atrypa Duntroonensis
''Atrypa'' is a genus of brachiopod with shells round to short egg-shaped, covered with many fine radial ridges (or costae), that split further out and growth lines perpendicular to the costae and 2-3 times wider spaced. The pedunculate valve is a little convex, but tends to level out or even become slightly concave toward the anterior margin (that is: opposite hinge and pedicle). The brachial valve is highly convex. There is no interarea (that is a flat area bordering the hinge line approximately perpendicular with the rest of the valve) in either valve. ''Atrypa'' was a cosmopolitan and occurred from the late Lower Silurian (Telychian) to the early Upper Devonian (Frasnian). Other sources expand the range from the Late Ordovician to Carboniferous, approximately from 449 to 336 Ma.''Atrypa'' at |
Brachiopod
Brachiopods (), phylum Brachiopoda, are a phylum of trochozoan animals that have hard "valves" (shells) on the upper and lower surfaces, unlike the left and right arrangement in bivalve molluscs. Brachiopod valves are hinged at the rear end, while the front can be opened for feeding or closed for protection. Two major categories are traditionally recognized, articulate and inarticulate brachiopods. The word "articulate" is used to describe the tooth-and-groove structures of the valve-hinge which is present in the articulate group, and absent from the inarticulate group. This is the leading diagnostic skeletal feature, by which the two main groups can be readily distinguished as fossils. Articulate brachiopods have toothed hinges and simple, vertically-oriented opening and closing muscles. Conversely, inarticulate brachiopods have weak, untoothed hinges and a more complex system of vertical and oblique (diagonal) muscles used to keep the two valves aligned. In many brachiopods, a ...

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 ...

Alluvium
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pialligo Avenue
Pialligo Avenue is a major arterial road in Canberra, the Capital city of Australia. It forms part of the corridor linking the city to Canberra Airport at Pialligo, and Fairbairn, Canberra, Fairbairn. It is also the most direct route from Queanbeyan, New South Wales, Queanbeyan to the airport precinct. Completed in 2009, a $16 million upgrade of Pialligo Avenue associated with the expansion of the airport saw the road upgraded to dual carriageway standard between its western terminus at the Monaro Highway and the Brindabella Business Park. These works included a grade separated intersection providing access to the redeveloped passenger terminal via a loop road. Substantial upgrades were also carried out at the intersection with Fairbairn Avenue. An estimated 30,000 vehicles use the road daily. Living history Just to the east of the Airport on Pialligo Avenue is the Pialligo#Living history, Redwood forest planted in 1918 by the city's designer, Walter Burley Griffin. See also ...
