Ranger Uranium Mine
The Ranger Uranium Mine was a uranium mine in the Northern Territory of Australia. The site is surrounded by, but separate from Kakadu National Park, 230 km east of Darwin. The orebody was discovered in late 1969, and the mine commenced operation in 1980, reaching full production of uranium oxide in 1981 and ceased stockpile processing on 8 January 2021. Mining activities had ceased in 2012. It is owned and operated by Energy Resources of Australia (ERA), a public company 86.33% owned by Rio Tinto Group, the remainder held by the public. Uranium mined at Ranger was sold for use in nuclear power stations in Japan, South Korea, China, UK, France, Germany, Spain, Sweden and the United States. The original Ranger 1 orebody was mined out by the end of 1995, although some ore remained stockpiled. A second orebody, Ranger 3, began mining in 1997. Both were open-pit mines. Mining finished at Ranger in late 2012 and the mine plant processed stockpiled ore until January 2021. ERA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
McArthur Basin
The McArthur Basin is a large intracratonic sedimentary basin in northern Australia, with an exposed area of about 180,000 km2. Most of it lies within the northeastern Northern Territory, but extends over the border into the state of Queensland. The basin contains thick (locally up to 12 km) marine and non-marine sedimentary rocks which were deposited from the late Paleoproterozoic to the early Mesoproterozoic (1800-1430 Ma). The basin also contains some volcanic rocks and related intrusive igneous rocks. The McArthur Basin hosts the world-class McArthur River mine (HYC) zinc-lead-silver deposit (not to be confused with McArthur River mine in Canada) and several smaller mineral and diamond Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic.

Orebody
Ore is natural Rock (geology), rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit.Encyclopædia Britannica. "Ore". Encyclopædia Britannica Online. Retrieved 7 April 2021Neuendorf, K.K.E., Mehl, J.P., Jr., and Jackson, J.A., eds., 2011, Glossary of Geology: American Geological Institute, 799 p. Ore is extracted from the earth through mining and treated or Refining (metallurgy), refined, often via smelting, to extract the valuable metals or minerals. The ''grade'' of ore refers to the concentration of the desired material it contains. The value of the metals or minerals a rock contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining, and is therefore considered an ore. Minerals of interest are generally Oxide mineral, oxides, Sulfide mineral, sulfides, silicate minerals, silicates, or native metals such as native copp ...

Nourlangie Rock
Burrunggui (sometimes spelled Burrunguy, previously called Nourlangie Rock) is located in an outlying sandstone formation of the Arnhem Land Escarpment within the Kakadu National Park in the Northern Territory of Australia. It is the traditional Country of the Gun-djeihmi speaking people and according to Traditional Owners, was shaped by Ancestral beings in the creation period of the Dreaming (Chaloupka 1982 p. 6). It was included on the World Heritage Register. Kakadu National Park is included on UNESCO the World Heritage List due to its exceptional natural and cultural values. Europeans were first in the area of Noulangie Rock in about 1845, after Ludwig Leichhardt’s explorations passed through the area. By the 1880s, European buffalo and buffalo shooters had moved into the area and local Traditional Owners joined their shooting parties. Traditional owners told the buffalo shooters about the Dreaming stories at Burrungui and the many names of all the natural features of ...

Supervising Scientist
The Supervising Scientist is a statutory office under Australian law, originally created to assist in the monitoring of what was then one of the world's largest uranium mines, the Ranger Uranium Mine. It now provides advice more generally on a 'wide range of scientific matters and mining-related environmental issues of national importance, including; radiological matters and tropical wetlands conservation and management'.Department of the Environment, Water, Heritage and the ArtsAbout the Supervising Scientist retrieved 21 October 2008 The Supervising Scientist is administered as a division within the Department of the Environment, Water, Heritage and the Arts.

Statutory Authority
A statutory body or statutory authority is a body set up by law (statute) that is authorised to implement certain legislation on behalf of the relevant country or state, sometimes by being empowered or delegated to set rules (for example regulations or statutory instruments) in their field. They are typically found in countries which are governed by a British style of parliamentary democracy such as the United Kingdom and the Commonwealth countries like Australia, Canada, India and New Zealand. They are also found in Israel and elsewhere. Statutory authorities may also be statutory corporations, if created as a body corporate. Australia Definitions Federal statutory authorities are established under the ''PGPA Act 2013''. "A statutory authority is a generic term for an authorisation by Parliament given to a person or group of people to exercise specific powers.

Alligator Rivers
Alligator Rivers is the name of an area in an Arnhem Land region of the Northern Territory of Australia, containing three rivers, the East, West, and South Alligator Rivers. It is regarded as one of the richest biological regions in Australia, with part of the region in the Kakadu National Park. It is an Important Bird Area (IBA), lying to the east of the Adelaide and Mary River Floodplains IBA. It also contains mineral deposits, especially uranium, and the Ranger Uranium Mine is located there. The area is also rich in Australian Aboriginal art, with 1500 sites. The Kakadu National Park is one of the few World Heritage sites on the list because of both its natural and human heritage values. They were explored by Lieutenant Phillip Parker King in 1820, who named them in the mistaken belief that the crocodiles in the estuaries were alligators. Rivers The East Alligator River is about long. After rising in the northern part of the Arnhem Land Plateau, it flows with tributary ...

Metasediment
In geology, metasedimentary rock is a type of metamorphic rock. Such a rock was first formed through the deposition and solidification of sediment Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand .... Then, the rock was buried underneath subsequent rock and was subjected to high pressures and temperatures, causing the rock to recrystallize. The overall composition of a metasedimentary rock can be used to identify the original sedimentary rock, even where they have been subject to high-grade metamorphism and intense deformation.

Proterozoic
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 chara ...

Formation (geology)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob ...

Nuclear Proliferation
Nuclear proliferation is the spread of nuclear weapons, fissionable material, and weapons-applicable nuclear technology and information to nations not recognized as " Nuclear Weapon States" by the Treaty on the Non-Proliferation of Nuclear Weapons, commonly known as the ''Non-Proliferation Treaty'' or ''NPT''. Proliferation has been opposed by many nations with and without nuclear weapons, as governments fear that more countries with nuclear weapons will increase the possibility of nuclear warfare (up to and including the so-called countervalue targeting of civilians with nuclear weapons), de-stabilize international or regional relations, or infringe upon the national sovereignty of nation states. Four countries besides the five recognized Nuclear Weapons States have acquired, or are presumed to have acquired, nuclear weapons: India, Pakistan, North Korea, and Israel. None of these four is a party to the NPT, although North Korea acceded to the NPT in 1985, then withdrew in 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supreme Court Of The Australian Capital Territory
The Supreme Court of the Australian Capital Territory is the highest court of the Australian Capital Territory (ACT). It has unlimited jurisdiction within the territory in civil matters and hears the most serious criminal matters. The court has the jurisdictional power to hear matters that relate to the Jervis Bay Territory, the Australian Antarctic Territory and the Heard Island and McDonald Islands, although it has never heard a case exercising its power over the Heard and McDonald Islands. It also hears matters on appeal from the Magistrates Court of the Australian Capital Territory. Whilst the Supreme Court is the highest Australian Capital Territory court in the Australian court hierarchy, an appeal by special leave can be made to the High Court of Australia. Matters of appeal can also be submitted to the ACT Court of Appeal, which is constituted by members of the Supreme Court. The Supreme Court consists of 5 permanent judges, including the chief justice of the Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
