Mount Saddleback
Mount Saddleback is the highest peak in the Darling Range of Western Australia. It is found at the easternmost part of the Darling Range about south of Boddington and west of Williams. Bauxite is mined on the flanks of the peak and processed at Worsley Alumina which has been in operation since 1984. The entire range is formed by the Darling Fault, a fault that has been moving continually through its long history with the last major activity occurring 135 million years ago when Australia broke away from the super continent, Gondwana. The Darling Scarp formed around 570 million years ago and is composed of 3700 million-year-old rocks that are mostly granite. Saddleback is found on the eastern side of the fault on the Darling Plateau. The underlying bedrock is composed of medium grained granite and sometimes Archean aged granitoids. The surface of the mount is an iron-rich hard cap with a thickness of around containing 40 to 50% Fe2O3 including significant amounts of quartz ...

Western Australia
Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Australia is Australia's largest state, with a total land area of . It is the second-largest country subdivision in the world, surpassed only by Russia's Sakha Republic. the state has 2.76 million inhabitants percent of the national total. The vast majority (92 percent) live in the south-west corner; 79 percent of the population lives in the Perth area, leaving the remainder of the state sparsely populated. The first Europeans to visit Western Australia belonged to the Dutch Dirk Hartog expedition, who visited the Western Australian coast in 1616.

Darling Range
The Darling Scarp, also referred to as the Darling Range or Darling Ranges, is a low escarpment running north–south to the east of the Swan Coastal Plain and Perth, Western Australia. The escarpment extends generally north of Bindoon, to the south of Pemberton. The adjacent Darling Plateau goes easterly to include Mount Bakewell near York and Mount Saddleback near Boddington. It was named after the Governor of New South Wales, Lieutenant-General Ralph Darling. History The feature was first recorded as General Darling Range by Charles Fraser, Government Botanist with Captain James Stirling aboard in March 1827. Maps from the 1830s show the scarp labelled " General Darlings Range"; this later became Darling Range, a name by which the formation was still commonly known in the late 20th century despite common understanding of it being an escarpment. There is also a tendency to identify the locations on or to the east of the scarp as being in the "Perth Hills" (or simpl ...

Boddington, Western Australia
Boddington is a town and Shire of Boddington, shire in the Peel (Western Australia), Peel region of Western Australia, located south-east of Perth. The town sits on the road from Pinjarra, Western Australia, Pinjarra to Williams, Western Australia, Williams on the Hotham River. The population of the town was 1,844 at the 2016 Census. History The town owes its name to an early settler, Henry Boddington, who was a farmer and shepherd in the 1860s and 1870s and leased land in the area in 1875, later moving to Wagin, Western Australia, Wagin. His name became associated with a pool in the Hotham River at which he frequently camped. The original settled locality was called Hotham, west of the town at what is now the end of Farmers Avenue, named for the Farmer family, and a post office and school were established. When the Hotham Valley Railway was being constructed in 1912 to meet demand created by the local timber industry, a townsite was chosen adjacent to the town, and subsequen ...

Williams, Western Australia
Williams is a town located in the Wheatbelt region of Western Australia, south-southeast of the state capital, Perth along Albany Highway and 32 kilometres (20 mi) west of Narrogin. The Williams River passes through the town. At the 2016 census, Williams had a population of 411. History Williams is named after the Williams River that flows nearby. The river was sighted by Captain Thomas Bannister in 1831 while leading the first overland expedition from the Swan River Colony to King George Sound (now Albany), and was first shown on an 1833 map. More than likely, the name honours King William IV, who reigned in the United Kingdom from June 1830 until June 1837. The first British claims on land in the area occurred in 1832. In 1835 a party led by Governor James Stirling and John Septimus Roe surveyed a route joining King George Sound with York via Williams to encourage inland settlement. No settlement occurred until after Lieutenant Henry Bunbury explored the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bauxite
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2). Bauxite appears dull in luster and is reddish-brown, white, or tan. In 1821, the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France. Formation Numerous classification schemes have been proposed for bauxite but, , there was no consensus. Vadász (1951) distinguished lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): * The carbonate bauxites occur predominantly in Europe, Guyana, Suriname, and Jamaica above carbonate rocks (limestone and do ...

Darling Fault
The Darling Fault is one of the longest and most significant faults in Australia, extending for at least 1500 km in a north–south orientation near the west coast of southern Western Australia. It is a major geological boundary separating the Archaean Yilgarn Craton in the east from the younger Pinjarra Orogen and overlying Phanerozoic Perth Basin to the west. The fault zone is very ancient and initially formed during the Proterozoic Eon. In the Perth area, the Darling Fault must once have coincided with the Darling Scarp, the abrupt escarpment immediately east of the city of Perth, but the scarp has since eroded eastward of the fault, leaving a formation of foothills known as the Ridge Hill Shelf. The fault is located on the western edge of the Ridge Hill Shelf; a good reference point of its location is the point where the Great Eastern Highway passes over the current Eastern railway line in Bellevue Bellevue means "beautiful view" in French. It may refer to: Pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gondwana
Gondwana () was a large landmass, often referred to as a supercontinent, that formed during the late Neoproterozoic (about 550 million years ago) and began to break up during the Jurassic period (about 180 million years ago). The final stages of break-up, involving the separation of Antarctica from South America (forming the Drake Passage) and Australia, occurred during the Paleogene. Gondwana was not considered a supercontinent by the earliest definition, since the landmasses of Baltica, Laurentia, and Siberia were separated from it. To differentiate it from the Indian region of the same name (see ), it is also commonly called Gondwanaland. Gondwana was formed by the accretion of several cratons. Eventually, Gondwana became the largest piece of continental crust of the Palaeozoic Era, covering an area of about , about one-fifth of the Earth's surface. During the Carboniferous Period, it merged with Laurasia to form a larger supercontinent called Pangaea. Gondwana (and Pan ...

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 ...

Archean
The Archean Eon ( , also spelled Archaean or Archæan) is the second of four geologic eons of Earth's history, representing the time from . The Archean was preceded by the Hadean Eon and followed by the Proterozoic. The Earth Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surfa ... during the Archean was mostly a water world: there was continental crust, but much of it was under an ocean deeper than today's ocean. Except for some trace minerals, today's oldest continental crust dates back to the Archean. Much of the geological detail of the Archean has been destroyed by subsequent activity. The Earliest known life forms, earliest known life started in the Archean. Life was simple throughout the Archean, mostly represented by shallow-water microbial mats called stromatolites, and the a ...

Kaolin
Kaolinite ( ) is a clay mineral, with the chemical composition Al2 Si2 O5( OH)4. It is an important industrial mineral. It is a layered silicate mineral, with one tetrahedral sheet of silica () linked through oxygen atoms to one octahedral sheet of alumina () octahedra. Rocks that are rich in kaolinite are known as kaolin () or china clay. Kaolin is occasionally referred to by the antiquated term lithomarge, from the Ancient Greek ''litho-'' and Latin ''marga'', meaning 'stone of marl'. Presently the name lithomarge can refer to a compacted, massive form of kaolin. The name ''kaolin'' is derived from Gaoling (), a Chinese village near Jingdezhen in southeastern China's Jiangxi Province. The name entered English in 1727 from the French version of the word: , following François Xavier d'Entrecolles's reports on the making of Jingdezhen porcelain. Kaolinite has a low shrink–swell capacity and a low cation-exchange capacity (1–15 meq/100 g). It is a soft, earthy, usu ...
