Stone Kerbing, Channels And Footbridges Of Charters Towers
The Stone kerbing, channels and footbridges of Charters Towers is a heritage-listed group of water infrastructure at various locations in Charters Towers City, Millchester, Queenton, and Richmond Hill throughout Charters Towers, Charters Towers Region, Queensland, Australia. It was built from to 1930s. It was added to the Queensland Heritage Register on 7 February 2005. History Charters Towers was a principal gold mining centre from 1872 to 1907 and by 1901 it was Queensland's second largest town. The stone kerbs and channels are significant in highlighting the areas of the town that were settled during the town's mining heyday. Most of the early granite kerbing and channeling at Charters Towers was constructed between and . Particularly fine examples of this work are evident with the original one square mile of the municipality, namely: Hodgkinson, Church, High, Lee, Bow, Anne, Mary and Deane Streets. The early granite kerbs and channeling form a unique pattern of drai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charters Towers, Queensland
Charters Towers is a rural town in the Charters Towers Region, Queensland, Australia. It is by road south-west from Townsville on the Flinders Highway. During the last quarter of the 19th century, the town boomed as the rich gold deposits under the city were developed. After becoming uneconomical in the 20th century, profitable mining operations have commenced once again. In the , Charters Towers had a population of 8,120 people. Geography and climate The urban area of the town of Charters Towers includes its suburbs: Charters Towers City (the centre of the city); Richmond Hill, Toll, and Columbia to the north, Queenton to the east, Grand Secret and Alabama Hill to the west, and Towers Hill, Mosman Park, and Millchester to the south. Charters Towers township is only mildly elevated at above sea-level, but this has a noticeable effect, with lower humidity and wider temperature variations compared to nearby Townsville. Charters Towers obtains its water supply from the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
City Of Charters Towers
The City of Charters Towers was a local government area in North Queensland, Australia, consisting of the centre and suburbs of the town of Charters Towers. Established in 1877, it was entirely surrounded by the Shire of Dalrymple, with which it amalgamated in 2008 to form the Charters Towers Region. History The Borough of Charters Towers was proclaimed on 21 June 1877 under the ''Municipal Institutions Act 1864''. It achieved a measure of autonomy in 1878 with the enactment of the ''Local Government Act''. With the passage of the ''Local Authorities Act 1902'', the Borough of Charters Towers became the Town of Charters Towers on 31 March 1903. On 13 April 1909, Charters Towers was proclaimed a City. A separate Shire of Queenton was excised from the surrounding Dalrymple Division on 2 July 1902 and merged with the City of Charters Towers on 23 December 1916. On 15 March 2008, under the ''Local Government (Reform Implementation) Act 2007'' passed by the Parliament of Queens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Handrail
A handrail is a rail that is designed to be grasped by the hand so as to provide safety or support. In Britain, handrails are referred to as banisters. Handrails are usually used to provide support for body or to hold clothings in a bathroom or similar areas. Handrails are commonly used while ascending or descending stairways and escalators in order to prevent injurious falls or to hold necessities. Handrails are typically supported by balusters or attached to walls. Similar items not covered in this article include bathroom handrails—which help to prevent falls on slippery, wet floors—other grab bars, used, for instance, in ships' galleys, and barres, which serve as training aids for ballet dancers. Guard rails and balustrades line drop-offs and other dangerous areas, keeping people and vehicles out. British specifications British Standard and British Standard Code of Practice are harmonized to European Normal (EN) series. Handrail height is set between . US speci ...

Span (architecture)
Span is the distance between two intermediate supports for a structure, e.g. a beam (structure), beam or a bridge. A span can be closed by a solid beam or by a rope. The first kind is used for bridges, the second one for power lines, overhead telecommunication lines, some type of Antenna (radio), antennas or for aerial tramways. The span is a significant factor in finding the strength and size of a beam as it determines the maximum bending moment and Deflection (engineering), deflection. The maximum bending moment M_ and deflection \delta_in the pictured beam is found using: :M_ = \frac :\delta_ = \frac = \frac where :q = Uniformly distributed load :L = Length of the beam between two supports (span) :E = Modulus of elasticity :I = Area moment of inertia Note that the maximum bending moment and deflection occur midway between the two supports. From this it follows that if the span is doubled, the maximum moment (and with it the tensile stress, stress) will quadruple, and ...

Dry Stone
Dry stone, sometimes called drystack or, in Scotland, drystane, is a building method by which structures are constructed from stones without any mortar to bind them together. Dry stone structures are stable because of their construction method, which is characterized by the presence of a load-bearing façade of carefully selected interlocking stones. Dry stone construction is best known in the context of stone walls, traditionally used for the boundaries of fields and churchyards, or as retaining walls for terracing, but dry stone sculptures, buildings, bridges, and other structures also exist. The term tends not to be used for the many historic styles which used precisely-shaped stone, but did not use mortar, for example the Greek temple and Inca architecture. The art of dry stone walling was inscribed in 2018 on the UNESCO representative list of the intangible cultural heritage of humanity, for dry stone walls in countries such as France, Greece, Italy, Slovenia, Cr ...

Mica
Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into extremely thin elastic plates. This characteristic is described as perfect basal cleavage. Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is particularly prominent in many granites, pegmatites, and schists, and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Micas are used in products such as drywalls, paints, fillers, especially in parts for automobiles, roofing and shingles, as well as in electronics. The mineral is used in cosmetics and food to add "shimmer" or "frost." Properties and structure The mica group is composed of 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards pseudohexagonal crystals, and are similar in structure but vary in chemical composition. Micas are ...

Feldspar
Feldspars are a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the ''plagioclase'' (sodium-calcium) feldspars and the ''alkali'' (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight. Feldspars crystalize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks. Compositions The feldspar group of minerals consists of tectosilicates, silicate minerals in which silicon ions are linked by shared oxygen ions to form a three-dimensional network. Compositions of major elements in common feldspars can be expressed in terms of three endmembers: * potassium feldspar (K-spar) ...

Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia. Quartz is the mineral defining the val ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Stone Kerbing, Channels And Footbridges Of Charters Towers - Boundary Map (2006)
In geology, rock (or stone) is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. It is categorized by the minerals included, its Chemical compound, chemical composition, and the way in which it is formed. Rocks form the Earth's outer solid layer, the Earth's crust, crust, and most of its interior, except for the liquid Earth's outer core, outer core and pockets of magma in the asthenosphere. The study of rocks involves multiple subdisciplines of geology, including petrology and mineralogy. It may be limited to rocks found on Earth, or it may include planetary geology that studies the rocks of other celestial objects. Rocks are usually grouped into three main groups: igneous rocks, sedimentary rocks and metamorphic rocks. Igneous rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed. Sedimentary rocks are formed by diagenesis and lithification of sediments, which in turn are formed by the weathe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
