Irwin River
The Irwin River is a river in the Mid West region of Western Australia. It was named on 9 April 1839 by the explorer George Grey, while on his second disastrous exploration expedition along the Western Australian coast, after his friend Major Frederick Irwin, the Commandant of the Swan River settlement, and later acting Governor of Western Australia from 1847 to 1848. The headwaters of the Irwin are located below Canna near Pindar. The river flows west until discharging into Arurine Bay near Dongara. The river passes through the Coalseam Conservation Park to the north of Mingenew which has a mixed geology of siltstones, claystone Mudrocks are a class of fine-grained siliciclastic sedimentary rocks. The varying types of mudrocks include siltstone, claystone, mudstone, slate, and shale.

Dongara, Western Australia
Dongara is a town north-northwest of Perth, Western Australia on the Brand Highway. The town is located at the mouth of the Irwin River. Dongara is the seat of the Shire of Irwin. At the the shire had a population of 3,569, with 2,782 residing in the contiguous towns of Dongara and Port Denison, Western Australia, Port Denison. History The place name 'Dongara' is an anglicised rendition of ''Thung-arra'', the local Wattandee people's name for the estuary adjacent to the town, meaning 'sea lion place'. European settlement around the estuary began in 1853 when a harbourmaster, Edward Downes, was stationed there to look out for passing ships. He was employed by Lockier Burges (Australian politician), Lockier Burges, Edward Hamersley (senior), Edward Hamersley, Samuel Pole Phillips and Bartholomew Urban Vigors' Cattle Company, which was granted 60,000 acres of pastoral leases about 15 kilometres inland.

Mid West (Western Australia)
The Mid West region is one of the nine regions of Western Australia. It is a sparsely populated region extending from the west coast of Western Australia, about north and south of its administrative centre of Geraldton, Western Australia, Geraldton and inland to east of Wiluna, Western Australia, Wiluna in the Gibson Desert. It has a total area of , and a permanent population of about 52,000 people, more than half of those in Geraldton. Earlier names The western portion of this region was known earlier as "The Murchison" based on the Murchison River (Western Australia), river of the same name, and the similarly named Goldfield. Economy The Mid West region has a diversified economy that varies with the geography and climate. Near the coast, annual rainfall of between allows intensive agriculture. Further inland, annual rainfall decreases to less than , and here the economy is dominated by mining of iron ore, gold, nickel and other mineral resources. Geraldton is an imp ...

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.

George Grey
Sir George Grey, KCB (14 April 1812 – 19 September 1898) was a British soldier, explorer, colonial administrator and writer. He served in a succession of governing positions: Governor of South Australia, twice Governor of New Zealand, Governor of Cape Colony, and the 11th premier of New Zealand. He played a key role in the colonisation of New Zealand, and both the purchase and annexation Annexation (Latin ''ad'', to, and ''nexus'', joining), in international law, is the forcible acquisition of one state's territory by another state, usually following military occupation of the territory.

Frederick Irwin
Lieutenant-Colonel Frederick Chidley Irwin, KH (22 March 1794 – 31 March 1860) was acting Governor of Western Australia from 1847 to 1848. Born in 1794 in Drogheda, Ireland, Frederick Chidley Irwin was the son of Reverend James Irwin. Some sources give the year 1788 as his birthyear. In 1808, he was commissioned into the 83rd (County of Dublin) Regiment of Foot.

Coalseam Conservation Park
Coalseam Conservation Park is a conservation park in the Shire of Mingenew, in the Wheatbelt region of Western Australia, approximately inland from Geraldton. The park is an important refuge for the threatened fauna and flora of the Wheatbelt region. It is renowned for its spectacular spring wildflowers. The park is also the site of the discovery of Western Australia's first coal deposits in 1846 and a rare example of coal being visible on the surface. Geology Coalseam Conservation Park is one of the few places on Earth where coal can be seen on the surface. The Irwin River, which flows through the park, exposes a cross section of the local rock, with the Holmwood Shale at the bottom (280 million years old), the High Cliff sandstone (269 million years old) above, the Irwin River Coal Measures (265 million years old) next and the Victoria Plateau Sandstone (50 million years old) and the Laterite (40 million years old) on top.

Mingenew, Western Australia
Mingenew is a town in Western Australia, located north of the state capital, Perth. It is the seat of government for the Shire of Mingenew. History Mingenew was named after Mingenew Spring, an Aboriginal word recorded by European settlers in 1856, possibly deriving from either the words ''Minga nu'' "the place of many ants and flies" or ''Mininoo'' "the place of many waters". Mingenew and the surrounding Irwin District were first explored by the brothers Augustus Charles and Francis Thomas Gregory in August 1847, looking for suitable grazing land. Settlement of the district then occurred in the 1850s because it was ideal country for cattle. The Midland railway line opened in August 1891, and private land was subdivided, followed in 1906 by subdivision of government land. In 1906, the town of Mingenew was gazetted. Agriculture Today, the town's economy is based on the farming of sheep, wheat and lupins. Mingenew is known as ''The Grain Centre''. The Mingenew grain f ...

Siltstone
Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility.Blatt ''et al.'' 1980, pp.381-382 Although its permeability and porosity is relatively low, siltstone is sometimes a tight gas reservoir rock, an unconventional reservoir for natural gas that requires hydraulic fracturing for economic gas production. Siltstone was prized in ancient Egypt for manufacturing statuary and cosmetic palettes. The siltstone quarried at Wadi Hammamat was a hard, fine-grained siltstone that resisted flaking and was almost ideal for such uses. Description There is not complete agreement on the definition of siltstone. One definition is that siltstone is mudrock ( clastic sedimentary rock containing at least 50% clay and silt) in which at least 2/3 of the clay and silt fraction is composed of silt-sized particles. Silt is defined a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Claystone
Mudrocks are a class of fine-grained siliciclastic sedimentary rocks. The varying types of mudrocks include siltstone, claystone, mudstone, slate, and shale. Most of the particles of which the stone is composed are less than and are too small to study readily in the field. At first sight, the rock types appear quite similar; however, there are important differences in composition and nomenclature. There has been a great deal of disagreement involving the classification of mudrocks. A few important hurdles to their classification include the following: # Mudrocks are the least understood and among the most understudied sedimentary rocks to date. # Studying mudrock constituents is difficult due to their diminutive size and susceptibility to weathering on outcrops. # And most importantly, scientists accept more than one classification scheme. Mudrocks make up 50% of the sedimentary rocks in the geologic record and are easily the most widespread deposits on Earth. Fine sedimen ...
