Murchison River (Western Australia)
The Murchison River is the second longest river in Western Australia. It flows for about from the southern edge of the Robinson Ranges to the Indian Ocean at Kalbarri. The Murchison-Yalgar-Hope river system is the longest river system in Western Australia. It has a mean annual flow of 208 gigalitres, although in 2006, the peak year on record since 1967, flow was 1,806gigalitres. Basin The Murchison River basin covers an area of about in the Mid West region of Western Australia. It extends about inland from the Indian Ocean, onto the Yilgarn Craton east of Meekatharra and north of Sandstone. Rain generally falls in the upper basin during summer cyclones, so for much of the year the Murchison River does not flow, leaving a dry sandy river bed and intermittent permanent pools. The eastern reaches of the basin contain large chains of salt lakes, which flow only following rainfall. The drainage lines from these lakes merge to form the Murchison River about north-northea ...

Murchison Gorge
Murchison River Gorge is a riverine gorge in Mid West (Western Australia), Mid West Western Australia. Carved by the meandering lower reaches of the Murchison River (Western Australia), Murchison River, it is more than long, and up to deep. It begins about north-northwest of Ajana, and extends to the mouth of the river at Kalbarri. A site of outstanding natural beauty, it is a major tourist attraction, with points of interest including the Z Bend lookout and The Loop (Murchison River), The Loop walking trail. The gorge is also of interest to geologists, with exposures of Tumblagooda sandstone, an Ordovician redbed formation that contains fossils of eurypterids, representing some of the earlier fossil evidence of land animals. Fossilised eurypterid tracks are common in the vicinity of the gorge, as are tracks of other arthropods, possibly trilobites. The gorge is considered to be in excellent condition and lies almost entirely within the Kalbarri National Park. It was nominate ...

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.

Ordovician
The Ordovician ( ) is a geologic period and system, the second of six periods of the Paleozoic 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 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 beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed 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 Geological Congress. Life continued to flourish during the Ordovician as it did in the earlier Cambrian P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Sequence
In geology, a sequence is a stratigraphic unit which is bounded by an unconformity at the top and at the bottom. Definition In a more rigorous and general way a sequence is defined as a "relatively conformable .. genetically related succession of strata bounded by unconformities or their correlative surfaces" Special cases and related concepts Special cases of sequences include type 1 sequences and type 2 sequences. A related concept are parasequences. Contrary to their name they are not smaller sequences. See also * Catena (soil) A catena in soil science (pedology) is a series of distinct but co-evolving soils arrayed down a slope. Each soil type or "facet" differs somewhat from its neighbours, but all occur in the same climate and on the same underlying parent material. A ... References Sequence stratigraphy {{Geology-stub ...

Tumblagooda Sandstone
The Tumblagooda Sandstone is a geological formation deposited during the Silurian or Ordovician periods, between four and five hundred million years ago, and is now exposed on the west coast of Australia in river and coastal gorges near the tourist town of Kalbarri, Kalbarri National Park and the Murchison River gorge, straddling the boundary of the Carnarvon and Perth basins. Visible trackways are interpreted by some to be the earliest evidence of fully terrestrial animals. Sedimentology The Tumblagooda ranges between in thickness. The base of the formation is not exposed, but geophysical data (primarily magnetic) indicate the sandstone unconformably overlies a Proterozoic basement. The formation is divided into four ''facies associations'' (FAs), numbered stratigraphically, that occur sequentially from bottom to top. These lithified sediments portray an environment dominated by high-energy braided streams flowing into the sea; some parts have been interpreted as ref ...

Kalbarri National Park
Kalbarri National Park is located north of Perth, in the Mid West region of Western Australia. The major geographical features of the park include the Murchison River gorge which runs for nearly on the lower reaches of the Murchison River. Spectacular coastal cliffs are located on the coast near the mouth of the Murchison River and the town of Kalbarri. Geography Kalbarri National Park preserves the inland desert regions of red and white striped Tumblagooda sandstone east of the town of Kalbarri, particularly the lower reaches of the Murchison River and its gorge, as well as the mouth of the river by Meanarra Hill. The western edge of the park protects the coastline south of the town which features cliffs more than high. The coastal area contains several wind and water eroded rock formations including a sea stack and a natural bridge. Climate The park is open all year round though temperatures can be extremely high from December through April. The park lies in the north ...

North West Coastal Highway
North West Coastal Highway is a generally north-south Western Australian highway which links the coastal city of Geraldton with the town of Port Hedland. The road, constructed as a sealed two-lane single carriageway, travels through remote and largely arid landscapes. Carnarvon is the only large settlement on the highway, and is an oasis within the harsh surrounding environment. The entire highway is allocated National Route 1, part of Australia's Highway 1, and parts of the highway are included in tourist routes Batavia Coast Tourist Way and Cossack Tourist Way. Economically, North West Coastal Highway is an important link to the Mid West, Gascoyne and Pilbara regions, supporting the agricultural, pastoral, fishing, and tourism industries, as well as mining and offshore oil and gas production. In Geraldton, the highway begins at a grade separated interchange with Brand Highway and roads providing access to the port and town centre. Two major roads link the Nor ...

Nannine, Western Australia
Nannine is a ghost town in the Mid West region of Western Australia. It is located on the northern bank of Lake Anneen, approximately south-southwest of Meekatharra, and north-northeast of Perth. Nannine was a former gold mining town, the site of the first discovery on the Murchison Goldfield. John Connelly discovered gold at the site northeast of Annean Station in 1890, prompting a gold rush to the area. The Murchison Goldfield was proclaimed in September 1891 and the town gazetted in 1893. It was the first town in the region. By 1894 the town was large enough to be given its own electoral district. In 1896 construction began on a railway between Nannine and Cue, Western Australia, which was completed in 1903. The continuation of the line to Meekatharra was begun in 1909. History Nannine is an Aboriginal name, "Nannine Wells" being first recorded by a surveyor in 1889. The meaning of the name is 'fat', used of a place in the indigenous landscape where the primordial D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reedy, Western Australia
Reedy is an abandoned town in the Murchison region of Western Australia. The town is located between Cue and Meekatharra in the Mid West region of Western Australia. Gold was discovered in the area by H. Reed in 1899–1900 and a nearby well, Reedy's Well, was named after him. The well appeared on maps of the area in 1908 as a known water source. Further gold discoveries were made in the 1930s and several mines were developed. By 1933 the Cue-Day Dawn Day Dawn is a ghost town in the Mid West/upper Murchison region of Western Australia. It was a significant mining town and mine in the late nineteenth century.

Binnu
Binnu is a town on the North West Coastal Highway in the Mid West region of Western Australia. The name derives from a well on the outskirts of town that was first in use in 1909. The name is Indigenous Australian in origin and is thought to mean either ''to squeeze'' or ''place of emus''. The townsite was gazetted in 1932. The main industry in the area is agriculture, particularly the production of wheat and lupins. The town was gripped by a two-year drought from 2006 then had a bumper crop in 2008. In 2009 up to 30% of crops were lost as a result of damage caused by a mouse plague. Sheep are also raised, particularly Merinos, although problems with salinity, erosion and drought are common. The main industry in town is wheat farming with the town being a Cooperative Bulk Handling The CBH Group (commonly known as CBH, an acronym for Co-operative Bulk Handling), is a grain growers' cooperative that handles, markets and processes grain from the wheatbelt of Western Austr ...

Ajana
Ajana is a townsite within the Shire of Northampton in Western Australia. It is located at the junction of Ajana-Kalbarri Road and Ajana Back Road, by road north of Northampton, by road southwest of Kalbarri, and west-northwest of Perth in the Mid West region. The name ''Ajana'' is Aboriginal in origin and is thought to be either the Nanda name for the area or to be derived from a similar word meaning "mine". History Ajana was the terminus of an extension to the first government railway line in Western Australia. The line originally ran from Northampton to Geraldton; it was extended to Ajana to encourage the development of lead mining and agriculture in the area. The station opened on 6 January 1913, and the townsite was declared on 26 November 1915. The railway terminated at the No 3 Rabbit Proof Fence, which ran through the townsite. A telegraph station, built in 1845 at nearby Mount View Station, provided early communications for the town. A post office was establi ...
