Black Mountain (Australian Capital Territory)
Black Mountain, also known as Galambary to the Ngunnawal people, is a small mountain with an elevation of that is situated to the west of the Canberra central business district on the northern shore of Lake Burley Griffin, in the Australian Capital Territory of Australia. Black Mountain is protected from development by the Canberra Nature Park and is predominantly covered in native bushland and is a haven to native wildlife. Location and features The mountain is located west of the main campus of the Australian National University and, together with the ridge, forms a natural west and northwestern boundary for Canberra city. Black Mountain rises above the water level of Lake Burley Griffin that lies at its base. Situated close to the highest point on the mountain is Black Mountain Tower (previously known as Telstra Tower, and Telecom Tower), a broadcasting tower rising a further above the summit. The Australian National Botanic Gardens and the CSIRO share the eastern b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telstra Tower
Telstra Tower (also known as Black Mountain Tower and formerly Telecom Tower) is a telecommunications tower and lookout that is situated above the summit of Black Mountain, Australian Capital Territory, Black Mountain in Australia's capital city of Canberra. It is named after Australia's largest telecommunications company, Telstra Corporation. The Tower sits within the InfraCo division, which is responsible for its operations and maintenance. Rising above the mountain summit, it is a landmark in Canberra and offers panoramic views of the city and its surrounding countryside from an indoor observation deck and two outdoor viewing platforms. History In April 1971 the Postmaster-General's Department, Postmaster General (PMG) at the time commissioned the Commonwealth Department of Housing and Construction to carry out a feasibility study in relation to a tower on Black Mountain accommodating both communication services and facilities for visitors. The tower was to replace the Microw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CSIRO

Parks In Canberra
A park is an area of natural, semi-natural or planted space set aside for human enjoyment and recreation or for the protection of wildlife or natural habitats. Urban parks are green spaces set aside for recreation inside towns and cities. National parks and country parks are green spaces used for recreation in the countryside. State parks and provincial parks are administered by sub-national government states and agencies. Parks may consist of grassy areas, rocks, soil and trees, but may also contain buildings and other artifacts such as monuments, fountains or playground structures. Many parks have fields for playing sports such as baseball and football, and paved areas for games such as basketball. Many parks have trails for walking, biking and other activities. Some parks are built adjacent to bodies of water or watercourses and may comprise a beach or boat dock area. Urban parks often have benches for sitting and may contain picnic tables and barbecue grills. The largest ... [...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 ...

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 ...

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 ...

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] |
Mount Ainslie
Mount Ainslie is a hill with an elevation of that is located in the northeastern suburbs of Canberra, in the Australian Capital Territory, Australia. Mount Ainslie lies within part of the Canberra Nature Park. Location and features Mount Ainslie borders on the inner suburbs of , and and is named in honour of James Ainslie, a 19th-century settler who was the overseer on ', a large property in the area. The Mount Ainslie tourist outlook, one of Canberra's most popular, provides excellent views of central Canberra and to the south and Black Mountain to the west, especially towards sunset. According to an article written in 1922, this outlook "will afford an ever changing bird's eye and panoramic picture of the city's buildings and beauty spots, as well as of the lovely plains that run to join the Yass Plains on the north." An air beacon located at the summit is part of the national capital's air navigation system guiding air traffic towards the nearby Canberra Airport. A w ...

Red Hill, Australian Capital Territory
Red Hill ( postcode: 2603) is a suburb of Canberra, Australian Capital Territory, Australia. The suburb is named after the northernmost hill of the ridge to the west of the suburb. The ridge is a reserve and managed as part of the Canberra Nature Park. The hill is an element of the central Canberra design axis. History The name 'Red Hill' was gazetted as a suburb name in 1928. This was the name associated with the hill since the days of the early settlers and probably suggested by the red soil in the area. Streets are named after ships and explorers. Mugga Way is named after an Aboriginal word also associated with the locality since the days of the early settlers. The hill was once part of the Narrabundah lease held by Charles Russell. He grazed sheep but as the suburb became built up, local pet dogs worried them and killed them. He changed to cattle and finally gave up the lease in 1992. The Red Hill Precinct or "Old Red Hill" is bounded by Mugga Way, Moresby Street, Arthur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
