Musgrave Ranges
Musgrave Ranges is a mountain range in Central Australia, straddling the boundary of South Australia (Anangu Pitjantjatjara Yankunytjatjara) and the Northern Territory (MacDonnell Shire), extending into Western Australia. It is between the Great Victoria Desert to the south and the Gibson Desert to the north. They have a length of and many peaks that have a height of more than , the highest being Mount Woodroffe at . Inhabitants They were originally inhabited by the indigenous Yankunytjatjara people. The English explorer William Gosse and his team were the first white people to visit the region in the 1870s. Gosse named the mountains after Anthony Musgrave, then Governor of South Australia. At the start of the 20th century, Yankunytjatjara people began migrating east, and groups of Pitjantjatjara moved into the Musgrave region from the west. Today, the majority of the families in the communities of Amata and Kaltjiti identify as Pitjantjatjara. In a historic decision freehold ...

South Australia
South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories by area, and second smallest state by population. It has a total of 1.8 million people. Its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 33,233. South Australia shares borders with all of the other mainland states, as well as the Northern Territory; it is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria, and to the south by the Great Australian Bight.M ...

Freehold Title
In English law, a fee simple or fee simple absolute is an estate in land, a form of freehold ownership. A "fee" is a vested, inheritable, present possessory interest in land. A "fee simple" is real property held without limit of time (i.e., permanently) under common law, whereas the highest possible form of ownership is a "fee simple absolute," which is without limitations on the land's use (such as qualifiers or conditions that disallow certain uses of the land or subject the vested interest to termination). The rights of the fee-simple owner are limited by government powers of taxation, compulsory purchase, police power, and escheat, and may also be limited further by certain encumbrances or conditions in the deed, such as, for example, a condition that required the land to be used as a public park, with a reversion interest in the grantor if the condition fails; this is a fee simple conditional. History The word "fee" is related to the term fief, meaning a feudal landhol ... [...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 ...

Petermann Ranges (Australia)
The Petermann Ranges are a mountain range in central Australia. They run across the border between Western Australia and the southwest corner of the Northern Territory. Their highest point is above sea level. The range was formed about 550 million years ago during the Petermann Orogeny. The existing geological research has broadly determined that the ''Petermann Ranges'' were equivalent in height to the Himalayas. The Petermanns were named for the geographer August Heinrich Petermann by Ernest Giles, the first European explorer to visit the area, and are commonly associated with the Yurliya ranges, nearby to the west. The area was included in the Katiti-Petermann Indigenous Protected Area in 2012. In popular culture There are few geology-oriented documentaries that trace Uluru and Kata Tjuta's origins with the Australian Petermann Ranges. ''The Time Traveller's Guide To Australia'' (2012) produced by the ABC TV and Essential Media explores the geological origins of the c ...

Olia Chain
The Olia Chain (or The Olias) is a small mountain range in the southwest of the Northern Territory, Australia. It forms the southeastern end of the Petermann Ranges and their connection with the Musgrave Ranges further south. The Olia Chain consists of scattered outcrops of rocky hills, separated and surrounded by sandy plains. It extends from Katamala Cone (828 m) at its northern end to Mantarur (including Butler's Dome, 1102 m) in the south. The centre of the chain is dominated by Stevenson Peak (1025 m). A few kilometres northeast of this peak is a Pitjantjatjara outstation, Pirrulpakalarintja. The Olia Chain mostly consist of flat-topped ridges composed of sandstone, slate, quartzite, and limestone rock beds.

Mineral Exploration
Mining in the engineering discipline is the extraction of minerals from underneath, open pit, above or on the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, and metallurgy, geotechnical engineering and surveying. A mining engineer may manage any phase of mining operations, from exploration and discovery of the mineral resources, through feasibility study, mine design, development of plans, production and operations to mine closure. With the process of Mineral extraction, some amount of waste and uneconomic material are generated which are the primary source of pollution in the vicinity of mines. Mining activities by their nature cause a disturbance of the natural environment in and around which the minerals are located. Mining engineers must therefore be concerned not only with the production and processing of mineral commodities, but also with the mitigation of damage to the environment both dur ...

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Uranium
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordially occurring elements. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few parts per million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Platinum Group
The platinum-group metals (abbreviated as the PGMs; alternatively, the platinoids, platinides, platidises, platinum group, platinum metals, platinum family or platinum-group elements (PGEs)) are six noble, precious metallic elements clustered together in the periodic table. These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 and 6). The six platinum-group metals are ruthenium, rhodium, palladium, osmium, iridium, and platinum. They have similar physical and chemical properties, and tend to occur together in the same mineral deposits. However, they can be further subdivided into the iridium-group platinum-group elements (IPGEs: Os, Ir, Ru) and the palladium-group platinum-group elements (PPGEs: Rh, Pt, Pd) based on their behaviour in geological systems. The three elements above the platinum group in the periodic table (iron, nickel and cobalt) are all ferromagnetic; these, including the lanthanide element gadolinium, are the only known tr ...

Exploration
Exploration refers to the historical practice of discovering remote lands. It is studied by geographers and historians. Two major eras of exploration occurred in human history: one of convergence, and one of divergence. The first, covering most of ''Human, Homo sapiens'' history, saw humans Recent African origin of modern humans, moving out of Africa, settling in new lands, and developing distinct cultures in relative isolation. Early explorers settled in Europe and Asia; 14,000 years ago, some crossed the Settlement of the Americas, Ice Age land bridge from Siberia to Alaska, and moved southbound to settle in the Americas. For the most part, these cultures were ignorant of each other's existence. The second period of exploration, occurring over the last 10,000 years, saw increased cross-cultural exchange through trade and exploration, and marked a new era of cultural intermingling, and more recently, convergence. Early writings about exploration date back to the 4th millennium B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
