Ediacara Hills
Ediacara Hills are a range of low hills in the northern part of the Flinders Ranges of South Australia, around north of the state capital of Adelaide. The hills are known for being the location of significant fossils, and have given their name to the geological period known as the Ediacaran. Description The area has many old copper and silver mines from mining activity during the late 19th century. The hills also contain fossils of early multicellular life forms, the Ediacaran biota (lagerstätte), and have given their name to the Ediacaran. There are two separate fossil sites within the region which have heritage protection: The Ediacara Fossil Site – Nilpena is listed on the Australian National Heritage List, while the Ediacara Fossil Reserve Palaeontological Site which is located to its north is listed on the South Australian Heritage Register. There is a settlement named Ediacara in the Ediacara Hills region, but it is small. Due to the placement of the hills with ...

Indigenous Australian Languages
The Indigenous languages of Australia number in the hundreds, the precise number being quite uncertain, although there is a range of estimates from a minimum of around 250 (using the technical definition of 'language' as non-mutually intelligible varieties) up to possibly 363. The Indigenous languages of Australia comprise numerous language families and isolates, perhaps as many as 13, spoken by the Indigenous peoples of mainland Australia and a few nearby islands. The relationships between the language families are not clear at present although there are proposals to link some into larger groupings. Despite this uncertainty, the Indigenous Australian languages are collectively covered by the technical term "Australian languages", or the "Australian family". The term can include both Tasmanian languages and the Western Torres Strait language, but the genetic relationship to the mainland Australian languages of the former is unknown, while the latter is Pama–Nyungan, thoug ...

Proterozoic Paleontological Sites Of Australia
The Proterozoic () is a geological eon spanning the time interval from 2500 to 538.8million years ago. It is the most recent part of the Precambrian "supereon". It is also the longest eon of the Earth's geologic time scale, and it is subdivided into three geologic eras (from oldest to youngest): the Paleoproterozoic, Mesoproterozoic, and Neoproterozoic. The Proterozoic covers the time from the appearance of oxygen in Earth's atmosphere to just before the proliferation of complex life (such as trilobites or corals) on the Earth. The name ''Proterozoic'' combines two forms of ultimately Greek origin: meaning 'former, earlier', and , 'of life'. The well-identified events of this eon were the transition to an oxygenated atmosphere during the Paleoproterozoic; the evolution of eukaryotes; several glaciations, which produced the hypothesized Snowball Earth during the Cryogenian Period in the late Neoproterozoic Era; and the Ediacaran Period (635 to 538.8 Ma) which is characterized ...

Precambrian Oceania
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons (Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards. The Precambrian fossil re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Ranges Of South Australia
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosystems of mountains: different elevations have different plants and animals. Because ...

Nilpena Ediacara National Park
__NOTOC__ Nilpena Ediacara National Park, comprising the former Ediacara Conservation Park and an additional , is a protected area located in the Australian state of South Australia about south west of the town of Leigh Creek in the state's Far North, around north of the city of Adelaide. The national park was proclaimed in June 2021. History Conservation park The Ediacara Conservation Park was proclaimed under the ''National Parks and Wildlife Act 1972'' on 26 April 2007 over land previously declared as a conservation reserve under the ''Crown Lands Act 1929'' in 1993 and as a fossil reserve in 1958. National park On 28 March 2019, the Government of South Australia purchased of adjacent land, to enlarge the conservation park by ten times. The land, formerly owned by the Nilpena Pastoral Company, extends as far as Lake Torrens National Park. The entire area was reclassified and proclaimed as Nilpena Ediacara National Park on 17 June 2021. A visitor hub and Ediacara Fossil ...

List Of Fossil Sites
This list of fossil sites is a worldwide list of localities known well for the presence of fossils. Some entries in this list are notable for a single, unique find, while others are notable for the large number of fossils found there. Many of the entries in this list are considered Lagerstätten (sedimentary deposits that exhibits extraordinary fossils with exceptional preservation—sometimes including preserved soft tissues). Lagerstätten are indicated by a note () in the noteworthiness column. Fossils may be found either associated with a geological formation or at a single geographic site. Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed. Such sites may have separate entries if they are considered to be more notable than the formation as a whole. In contrast, extensive formations associated with large areas m ...

Ediacara, South Australia
__NOTOC__ Ediacara is a locality in the state of South Australia, located about north of the state capital of Adelaide and about to the south west of the town of Leigh Creek. It includes the Nilpena Ediacara National Park, and the Ediacara Hills, which lie within that park. History The area has a history of mining, first reported in 1888. An area became known as the Ediacara Mines after more costeans were dug. Attempts to mine the area were carried out as recently as 1967 by C.R.A. Exploration, which used diamond drilling to explore the ground, but this was abandoned after they proved fruitless. As of 2012, the area was still able to be accessed for "licensed mineral exploration or mining activities". The locality was established on 26 April 2013 in respect to "the long established local name". Its name is derived from the use of "Ediacara" in the names of features such as Ediacara Range. Location and description The locality of Ediacara is located about north of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NITV
National Indigenous Television (NITV) is an Australian free-to-air television channel that broadcasts programming produced and presented largely by Aboriginal and Torres Strait Islander people. It includes the half-hourly nightly ''NITV News'', with programming including other news and current affairs programmes, sports coverage, entertainment for children and adults, films and documentaries covering a range of topics. Its primary audience is Indigenous Australians, but many non-Indigenous people tune in to learn more about the history of and issues affecting the country's First Nations peoples. NITV was initially only carried by cable and satellite providers, along with some limited over-the-air transmissions in certain remote areas. NITV was re-launched in December 2012 by the Special Broadcasting Service (SBS) as a free-to-air channel. History Predecessors of NITV Indigenous groups and individuals lobbied the Australian Government to fund a nationwide Indigenous televisi ...

Igneous Rock
Igneous rock (derived from the Latin word ''ignis'' meaning fire), or magmatic rock, is one of the three main The three types of rocks, rock types, the others being Sedimentary rock, sedimentary and metamorphic rock, metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from Partial melting, partial melts of existing rocks in either a Terrestrial planet, planet's mantle (geology), mantle or crust (geology), crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive (geology), extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form Volcanic glass, natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...
