Acacia Hamersleyensis
''Acacia hamersleyensis'', also known as Karijini wattle or Hamersley Range wattle, is a tree or shrub belonging to the genus ''Acacia'' and the subgenus ''Juliflorae''. It is endemic to a small area in central Western Australia. Description The spindly spreading tree or shrub typically grows to a height of . It can be spreading, bushy or openly branched or have a rounded or obconic habit with up to six main stems emerging from ground level. Older specimens can appear gnarled with a spreading sparse canopy. The dark brown to grey or black coloured bark can be smooth on higher branches but longitudinally fissured and fibrous on the main stems especially toward the base. The glabrous branchlets have a yellowish to light brown colour sometimes with a pale powdery coating that is a more orange colour at the extremities. Like most species of ''Acacia'' it has phyllodes rather than true leaves. The glabrous narrowly elliptic phyllodes are slightly asymmetric with a length of and a widt ...

Hamersley Range
The Hamersley Range is a mountainous region of the Pilbara region of Western Australia. The range was named on 12 June 1861 by explorer Francis Thomas Gregory after Edward Hamersley (senior), Edward Hamersley, a prominent promoter of his exploration expedition to the northwest. Juukan Gorge lies within the ranges, as does Karijini National Park (formerly known as Hamersley Range National Park). History The Aboriginal Australians, traditional Aboriginal owners of the area that the range runs through are the Kurrama people, Puutu Kunti Kurrama and Pinikura peoples. In 1999 a small range within the Hamersley was named the Hancock Range after the Hancock family, who were pioneers in the area. The Hancock range is east of Karijini National Park in a region of broad valleys and peaks that rise to almost . The Hancock Range is close to Mulga Downs Station, a property owned by the Hancock family and where Lang Hancock is buried. Geography The range runs from the Fortescue River in ...

Acacias Of Western Australia
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species. This meant that the Australasian lineage (by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Acacia Species
Several Cladistics, cladistic analyses have shown that the genus ''Acacia sensu lato, Acacia'' is not monophyletic. While the subg. ''Acacia'' and subg. ''Phyllodinae'' are monophyletic, subg. ''Aculeiferum'' is not. This subgenus consists of three clades. Therefore, the following list of ''Acacia'' species cannot be maintained as a single entity, and must either be split up, or broadened to include species previously not in the genus. This genus has been provisionally divided into 5 genus, genera, ''Acacia'', ''Vachellia'', ''Senegalia'', ''Acaciella'' and ''Mariosousa''. The proposed type species of ''Acacia'' is ''Acacia penninervis''. Which of these segregate genera is to retain the name ''Acacia'' has been controversial. The genus was previously typified with the African species ''Acacia scorpioides'' (L.) W.F.Wright, a synonym of ''Acacia nilotica'' (L.) Delile. Under the original typification, the name ''Acacia'' would stay with the group of species currently recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ironstone
Ironstone is a sedimentary rock, either deposited directly as a ferruginous sediment or created by chemical replacement, that contains a substantial proportion of an iron ore compound from which iron (Fe) can be smelted commercially. Not to be confused with native or telluric iron, which is very rare and found in metallic form, the term ''ironstone'' is customarily restricted to hard, coarsely banded, non-banded, and non-cherty sedimentary rocks of post-Precambrian age. The Precambrian deposits, which have a different origin, are generally known as banded iron formations. The iron minerals comprising ironstones can consist either of oxides, i.e. limonite, hematite, and magnetite; carbonates, i.e. siderite; silicates, i.e. chamosite; or some combination of these minerals.U.S. Bureau of Mines Staff (1996) ''Dictionary of Mining, Mineral, & Related Terms.''

Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically have a concave upwards form, where the maximum inclination corresponds to the angle of repose of the mean debris particle size. The exact definition of scree in the primary literature is somewhat relaxed, and it often overlaps with both ''talus'' and ''colluvium''. The term ''scree'' comes from the Old Norse term for landslide, ''skriða'', while the term ''talus'' is a French word meaning a slope or embankment. In high-altitude arctic and subarctic regions, scree slopes and talus deposits are typically adjacent to hills and river valleys. These steep slopes usually originate from late-Pleistocene periglacial processes. Notable scree sites in Eastern North America include the Ice Caves at White Rocks National Recreation Area in southern Ve ...

Little Sandy Desert
The Little Sandy Desert (LSD) is a desert region in the state of Western Australia, lying to the east of the Pilbara and north of the Gascoyne regions. It is part of the Western Desert cultural region, and was declared an interim Australian bioregion in the 1990s. History Indigenous groups that have identified with the region include the Mandilara, an Aboriginal Australian group who are regarded as the traditional owners of the land. Today the group recognised as traditional owners are the Martu people. The desert is crossed by the Canning Stock Route, an historic stock route created in the early 20th century. Description The Little Sandy Desert covers around and adjoins the Great Sandy Desert (, to the north) and the Gibson Desert (, to the east), all of which lie within the huge Australian Arid Zone which covers the centre of the Australian continent. It lies east of the Pilbara region, and north of Gascoyne, and is part of the Western Desert. To the north the nearest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paraburdoo, Western Australia
Paraburdoo is a mining town in the Pilbara region of Western Australia. The region is served by Paraburdoo Airport, which is situated from the town. Etymology The name of the town comes from an Aboriginal word said to mean "feathered meat", which could refer to abundant Little corella or flock pigeons. It could also mean Rock Cave (para means rock and buradoo means hole or cave) to refer to caves nearby. Economy Paraburdoo was developed in the early 1970s to support Hamersley Iron's (now Pilbara Iron) local iron ore mining operations, and was gazetted as a town in 1972. The town provides housing to workers of the three nearby Rio Tinto mines, those being the Channar, Eastern Range and Paraburdoo mine.Mining Rio Tinto Iron Ore website, accessed: 6 November 2010 Geography Paraburdoo is located north ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wittenoom, Western Australia
Wittenoom is a declared contaminated site and former townsite north-north-east of Perth, in the Hamersley Range in the Pilbara region of Western Australia. The declared contaminated site comprises , making it the "largest contaminated site in the southern hemisphere". The area around Wittenoom was mainly pastoral until the 1930s when mining for blue asbestos began in the area. By 1939, major mining began in Yampire Gorge, which was subsequently closed in 1943 when mining began in Wittenoom Gorge. In 1947 a company town was built, and during the 1950s it was the Pilbara's largest town. The peak population, as recorded by the Australian census conducted on 30 June 1961, was 881 (601 males and 280 females). During the 1950s and early 1960s Wittenoom was Australia's only supplier of blue asbestos. The mine was shut down in 1966 due to unprofitability and growing health concerns from asbestos mining in the area. The former townsite no longer receives government services. In Dece ...
