Jerdacuttup River
Jerdacuttup River is a river located in the Goldfields-Esperance region of Western Australia. The water in the river is naturally saline. The river rises on the edge of the Yilgarn Plateau north of Ravensthorpe below Mount Short and drains the eastern side of the Ravensthorpe Range before flowing south and draining into the Jerdacuttup lakes close to the Southern Ocean and east of Hopetoun. The tributaries of the river include Moolyall Creek, Woodenup Creek, Cordingup Creek, Carlingup Creek, Boaiup Creek, Bandalup Creek and Burlabup Creek. The name is Indigenous Australian in origin and first charted by John Forrest in 1870. The river is the location of a significant komatiite deposit See also *Widgiemooltha Komatiite The Widgiemooltha Komatiite is a formation of komatiite in the Yilgarn Craton of Western Australia.

Ravensthorpe, Western Australia
Ravensthorpe is a town 541 km south-east of Perth and 40 km inland from the south coast of Western Australia. It is the seat of government of the Shire of Ravensthorpe. At the , Ravensthorpe had a population of 438. In 1848, the area was surveyed by Surveyor General John Septimus Roe who named many of the geographical features nearby, including the nearby Ravensthorpe Range that the later town was named after. There was one of the Western Australian Government Railways isolated branch lines between Hopetoun and Ravensthorpe. This line opened in 1909. Alluvial gold was discovered at the Phillips River in 1892. At the goldfield a ''de facto'' town emerged, known as ''Phillips River''. The government completed construction of a copper and gold smelter about 2 km south east of the town in 1906, used to cast copper and gold ingots. History A temporary pastoral lease ("Free Run") was registered by James Dunn senior in 1868. His five sons and daughter started she ...

Jerdacuttup Lakes
Jerdacuttup is a small town in Western Australia east-south-east of Perth between Ravensthorpe and Hopetoun in the Goldfields–Esperance region of Western Australia. At the 2006 census, Jerdacuttup had a population of six. John Forrest explored the area in 1870 and spelt the word as ''Jerdicutup''; the area was later surveyed in 1875 by C Price who recorded the name of the area as ''Jerdicat'' and ''Verdicat''. ''Jerdacuttup'' is an Aboriginal word of unknown meaning. During the 1960s the south-east of Western Australia was opened for agricultural purposes and the town was developed as a supply centre for the region. The government gazetted the townsite in 1966. The dominant agricultural industry in the area is sheep grazing and cereal cropping with cattle grazing and lupin cropping to a lesser extent. The town is no longer a receival site for Cooperative Bulk Handling. The Jerdacuttup River is situated about 16 km to the west of the townsite. Australian under ...

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. The first permanent European colony of Western Australia occurred following the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saline Water
Saline water (more commonly known as salt water) is water that contains a high concentration of dissolved salts (mainly sodium chloride). On the United States Geological Survey (USGS) salinity scale, saline water is saltier than brackish water, but less salty than brine. The salt concentration is usually expressed in parts per thousand (permille, ‰) and parts per million (ppm). The USGS salinity scale defines three levels of saline water. The salt concentration in slightly saline water is 1,000 to 3,000 ppm (0.1–0.3%); in moderately saline water is 3,000 to 10,000 ppm (0.3–1%); and in highly saline water is 10,000 to 35,000 ppm (1–3.5%). Seawater has a salinity of roughly 35,000 ppm, equivalent to 35 grams of salt per one liter (or kilogram) of water. The saturation level is only nominally dependent on the temperature of the water. At one liter of water can dissolve about 357 grams of salt, a concentration of 26.3% w/w. At boiling () the amount that can be dissolved in o ...

Yilgarn Craton
The Yilgarn Craton is a large craton that constitutes the bulk of the Western Australian land mass. It is bounded by a mixture of sedimentary basins and Proterozoic fold and thrust belts. Zircon grains in the Jack Hills, Narryer Terrane have been dated at ~4.27 Ga, with one detrital zircon dated as old as 4.4 Ga. The Murchison Province of the craton contains the oldest dated meteorite impact crater, at 2229 ± 5 Ma. Geology The Yilgarn Craton appears to have been assembled between ~2.94 and 2.63 Ga by the accretion of a multitude of formerly present blocks or terranes of existing continental crust, most of which formed between 3.2 Ga and 2.8 Ga. This accretion event is recorded by widespread granite and granodiorite intrusions, which comprise over 70% of the Yilgarn craton; voluminous tholeiitic basalt and komatiite volcanism; regional metamorphism and deformation as well as the emplacement of the vast majority of the craton's endowment in gold mineralisation. These acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Ocean
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. With a size of , it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean. Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem. By way of his voyages in the 1770s, James Cook proved that waters encompassed the southern latitudes of the globe. Since then, geographers have disagreed on the Southern Ocean's northern boundary or even existence, considering the waters as various parts of the Pacific, Atlantic, and Indian oceans, instead. However, according to Commodore John Leech of the International Hydrographic Organization (IHO), recent oceanographic research has discovered the importance of Southern ...

Hopetoun, Western Australia
Hopetoun is a town on the south coast of Western Australia in the Shire of Ravensthorpe. Located on Mary Ann Harbour, Hopetoun is south-east from capital city Perth and west of Esperance. History Mary Ann Harbour was named in November 1865 by the sealer James Sale on the cutter ''Mary Ann''. The ''Mary Ann'' was owned by whaling master John Thomas of Cheyne's Beach, east of Albany, who had named it after his eldest daughter. Hopetoun was established in 1900 as the port servicing the Phillips River goldfield, named after the first Governor-General of Australia, John Hope, 7th Earl of Hopetoun. The townsite was gazetted on 9 February 1901. The town became a shipping port for the mining industry, with a jetty built in 1901, the terminus of a railway line between Hopetoun and Ravensthorpe that operated from 1909 to 1935. The port was closed in 1937, with the jetty remaining until its destruction in 1983. Some of the town's electricity is generated by a wind-diesel system. ...

Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & S ...

Indigenous Australian
Indigenous Australians or Australian First Nations are people with familial heritage from, and membership in, the ethnic groups that lived in Australia before British colonisation. They consist of two distinct groups: the Aboriginal peoples of the Australian mainland and Tasmania, and the Torres Strait Islander peoples from the seas between Queensland and Papua New Guinea. The term Aboriginal and Torres Strait Islander peoples or the person's specific cultural group, is often preferred, though the terms First Nations of Australia, First Peoples of Australia and First Australians are also increasingly common; 812,728 people self-identified as being of Aboriginal and/or Torres Strait Islander origin in the 2021 Australian Census, representing 3.2% of the total population of Australia. Of these indigenous Australians, 91.4% identified as Aboriginal; 4.2% identified as Torres Strait Islander; while 4.4% identified with both groups.

John Forrest
Sir John Forrest (22 August 1847 – 2 SeptemberSome sources give the date as 3 September 1918 1918) was an Australian explorer and politician. He was the first premier of Western Australia (1890–1901) and a long-serving cabinet minister in federal politics. Forrest was born in Bunbury, Western Australia, to Scottish immigrant parents. He was the colony's first locally born surveyor, coming to public notice in 1869 when he led an expedition into the interior in search of Ludwig Leichhardt. The following year, Forrest accomplished the first land crossing from Perth to Adelaide across the Nullarbor Plain. His third expedition in 1874 travelled from Geraldton to Adelaide through the centre of Australia. Forrest's expeditions were characterised by a cautious, well-planned approach and diligent record-keeping. He received the Patron's Medal of the Royal Geographical Society in 1876. Forrest became involved in politics through his promotion to surveyor-general, a powerful posi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
