Spinifex (coastal Grass)
''Spinifex'' is a genus of perennial coastal plants in the grass family. They are one of the most common plants that grow in sand dunes along the coasts of Africa, Middle East, Asia, Australia, New Zealand, and New Caledonia, with the ranges of some species extending north and west along the coasts of Asia as far as India and Japan. As they help stabilise the sand, these grasses are an important part of the entire sand dune ecosystem. The single species indigenous to New Zealand, ''Spinifex sericeus'', is also found in Australia. Confusingly, the word "spinifex" is also used as a common name referring to grasses in the related genus '' Triodia''. ''Triodia'' however is native to inland Australia and refers to a group of spiny-leaved, tussock-forming grasses. Species Species include: * ''Spinifex'' × ''alterniflorus'' Nees – Western Australia * '' Spinifex hirsutus'' Labill. – all 6 states of Australia * '' Spinifex littoreus'' (Burm.f.)

Triodia (plant)
''Triodia'' is a large genus of hummock-forming bunchgrass endemic to Australia. They are known by the common name spinifex, although they are not a part of the coastal genus '' Spinifex''. Many of the soft-leaved members of this species were formerly included in the genus ''Plectrachne''. It is known as ''tjanpi'' in central Australia, and is used for basket weaving by the women of various Aboriginal Australian peoples. A multiaccess key (SpiKey) is available as a free application for identifying the ''Triodia'' of the Pilbara (28 species and one hybrid). Description ''Triodia'' is a perennial Australian tussock grass that grows in arid regions. Its leaves (30–40 centimetres long) are subulate ( awl-shaped, with a tapering point). The leaf tips, that are high in silica, can break off in the skin, leading to infections. Uses Spinifex has traditionally had many uses for Aboriginal Australians. The seeds were collected and ground to make seedcakes. Spinifex resin was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Texture (geology)
In geology, texture or rock microstructure refers to the relationship between the materials of which a rock is composed. The broadest textural classes are crystalline (in which the components are intergrown and interlocking crystals), fragmental (in which there is an accumulation of fragments by some physical process), aphanitic (in which crystals are not visible to the unaided eye), and glassy (in which the particles are too small to be seen and amorphously arranged).Texture & Genesis of Rocks, Introductory Geology Laboratory, Christopher DiLeonardo, Ph.D., Marek Cichanski, Ph.D., Earth & Space Sciences, De Anza College The geometric aspects and relations amongst the component particles or crystals are referred to as the '' crystallographic texture'' or ''preferred orientation''. Textures can be quantified in many ways. The most common parameter is the crystal size distribution. This creates the physical appearance or character of a rock, such as grain size, shape, arrangement, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Komatiite
Komatiite () is a type of ultramafic mantle-derived volcanic rock defined as having crystallised from a lava of at least 18 wt% MgO. Komatiites have low silicon, potassium and aluminium, and high to extremely high magnesium content. Komatiite was named for its type locality along the Komati River in South Africa, and frequently displays spinifex texture composed of large dendritic plates of olivine and pyroxene. Komatiites are rare rocks; almost all komatiites were formed during the Archaean Eon (4.0–2.5 billion years ago), with few younger (Proterozoic or Phanerozoic) examples known. This restriction in age is thought to be due to cooling of the mantle, which may have been hotter during the Archaean. The early Earth had much higher heat production, due to the residual heat from planetary accretion, as well as the greater abundance of radioactive isotopes, particularly shorter lived ones like uranium 235 which produce more decay heat. Lower temperature mantle melts such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinifex People
The Pila Nguru, often referred to in English as the Spinifex people, are an Aboriginal Australian people of Western Australia, whose lands extend to the border with South Australia and to the north of the Nullarbor Plain. The centre of their homeland is in the Great Victoria Desert, at Tjuntjunjarra, some east of Kalgoorlie, perhaps the remotest community in Australia. Their country is sometimes referred to as Spinifex country. The Pila Nguru were the last Australian people to have dropped the complete trappings of their traditional lifestyle. They maintain in large part their traditional hunter-gatherer lifestyle within the territory, over which their claims to native title in Australia and associated collective rights were recognised by a 28 November 2000 Federal Court decision. In 1997, an art project was started in which Indigenous paintings became part of the title claim. In 2005, a major exhibit of their works in London brought the artists widespread attention. Langu ...

Spinifex Arts Project
Tjuntjuntjara is a large Aboriginal community located 650 km north east of Kalgoorlie in the Goldfields–Esperance region of Western Australia, within the Shire of Menzies in the southern part of the Great Victoria Desert. The community relies upon regular supplies trucked from Ceduna in South Australia. History The community was established in 1988 after a water bore was drilled at the location. The Tjuntjuntjara community members are part of a larger group known as the Spinifex people, who were removed from their homelands (which range across the WA and SA border lands) prior to the British nuclear tests at Maralinga in the 1950s and 1960s. Native title The community is located within the fully determined Spinifex People (WAD6043/98) native title claim area. Governance The community is managed through its incorporated body, Paupiyala Tjarutja Aboriginal Corporation, incorporated under the ''Aboriginal Councils and Associations Act 1976'' on 19 April 1989. ...

Spinifex Gum
Spinifex Gum is an Australian musical collective based in Cairns, a collaboration between the Indigenous ensemble the Marliya Choir, Felix Riebl and Ollie McGill of the Melbourne band The Cat Empire, Lyn Williams, and Deborah Brown. The performers share the stories of the Yindjibarndi people in the Pilbara region of Western Australia. Origin Spinifex Gum has its origins in a 2014 visit by the Gondwana Indigenous Children's Choir and the founder of Gondwana Choirs, Lyn Williams, to the Pilbara, inviting Melbourne musician Felix Riebl. The group met and began a collaboration with the Yindjibarndi community, and Reibl returned seven times over the following seven years to learn the stories of the community and their ancestors. In 2015 Riebl was commissioned by Gondwana Choirs to compose an original work inspired by the Pilbara region. He worked with his friend and Cat Empire bandmate Ollie McGill and the Marliya Choir, a group formed from the Indigenous Children's Choir for t ...

Spinifex Hopping Mouse
The spinifex hopping mouse (''Notomys alexis''), also known as the tarkawara or tarrkawarra, occurs throughout the central and western Australian arid zones, occupying both spinifex-covered sand flats and stabilised sand dunes, and loamy mulga and melaleuca flats. The population fluctuates greatly: in normal years it is sparsely distributed and probably confined to sandy country; after rain the population explodes and spreads to other types of habitat for a time. They are mostly seen at night, bounding across open ground on their large hind feet, with tails extended and the body almost horizontal. As semi-fossorial, burrowing surface foragers, the tiny hopping mice spend a great deal of energy not just foraging for food, but also transporting it back to their burrows. In fact, it was found that the total energy spent on transporting food in relation to energy investment on burrows far outweighed any other similar type of species (White, 2006). Appearance The appearance is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spinifex Pigeon
The spinifex pigeon (''Geophaps plumifera''), also known as the plumed-pigeon or gannaway pigeon, is one of four endemic Australian bird species within the genus ''Geophaps''. It occurs within a broader group known as bronzewing pigeons. This species is listed under the International Union for Conservation of Nature (IUCN) Red List category of "least concern". It most frequently occurs in arid and semi-arid habitats containing hummock-forming grasses of the genera ''Triodia (grass), Triodia'' and ''Plectrachne''. Taxonomy John Gould described the spinifex pigeon in 1842 and there have been several revisions at both the species and subspecies level. The current taxonomy was determined through a comprehensive examination of twelve variables in 712 specimens from 54 localities. Three subspecies are recognised: # Eastern spinifex pigeon (central eastern white-bellied subspecies) ''Geophaps plumifera leucogaster'' # North-western spinifex pigeon (north-western white-bellied subspecies ...

Spinifex Resin
Spinifex resin is a gum coating of some species of spinifex grasses. This sticky resin was traditionally used as an adhesive in tool making by Aboriginal Australians. Many species of spinifex are extremely resinous, to the extent that resin may drip down the stems and leaves on hot days, and large residual lumps of resin often may be seen at the bases of hummocks which have burned. Making the gum The spinifex is threshed until the resin particles fall free. These particles are heated until they fuse together to form a moldable black tar which is worked while warm. When set, this gum is quite strong. The preparation of spinifex for hafting use is similar to that of ''Xanthorrhoea''. It is thought to have been preferable to ''Xanthorrhoea'' for hafting, due to its ability to be re-heated and remodelled several times without going brittle. The resin can be re-softened using fire and some moisture. Most historical accounts of resin processing described Aboriginal men doing the wo ...

Spinifex Ridge Mine
Spinifex Ridgem mine is an inactive iron ore mine in the Pilbara region of Australia, northeast of Marble Bar. Overview Moly Mines awarded production contracts to BGC Contracting in August 2010. Initially, there were plans for an open pit molybdenum/copper mine producing per year; with changes in the price of molybdenum, this was downsized to per year. Port facilities at Port Hedland were commissioned in September 2010 Iron ore mining began in November 2010; ramping up to a throughput of per year. The mine had been the subject of a legal dispute during and after the final stages of production. Moly Mines had conducted a mine gate sales agreement with Mineral Resources Limited, under which the latter paid A$35 million in advance for an expected 2.4 million tonnes of iron ore from the mine. Concluded in 2013, the deal was to extend to the completion of mining at Spinifex Ridge, with a final payment in the range of A$3 million due upon this. As part of this agreement, Moly M ...
