Kvanefjeld
Kvanefjeld (or Kuannersuit), in Greenland, is the site of a mineral deposit, which is claimed to be the world's second-largest deposit of rare-earth oxides, and the sixth-largest deposit of uranium. There are also substantial sodium fluoride deposits, and Kvanefjeld is thought to be one of the largest multi-element deposits of its kind in the world. Geology The Kvanefjeld site is part of the Ilimaussaq intrusive complex. Rare earths and uranium are typically concentrated in lujavrite. Lujavrite, a dark agpaitic nepheline syenite, occurs as an internal layer in the north Ilimaussaq complex. The uppermost sections generally have the highest rare-earth elements, uranium and zinc grades. Lujavrite is a rare variety of nepheline syenite having amphibole, aegirine pyroxene, nepheline and feldspar. The red spots in the rock are crystals of the rare halide mineral villiaumite (NaF - sodium fluoride). Kvanefjeld is already known among mineral collectors as a source of fluorescent ...

Rare-earth
The rare-earth elements (REE), also called the rare-earth metals or (in context) rare-earth oxides or sometimes the lanthanides (yttrium and scandium are usually included as rare earths), are a set of 17 nearly-indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare earths have diverse applications in electrical and electronic components, lasers, glass, magnetic materials, and industrial processes. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties, but have different electronic and magnetic properties. These metals tarnish slowly in air at room temperature and react slowly with cold water to form hydroxides, liberating hydrogen. They react with steam to form oxides, and at elevated temperature (400°C) ignite spontaneously. These elements and their compounds have no biological function other than in several specialized enzymes, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kujalleq
Kujalleq ( Greenlandic: , da, Den Syden, lit=The South) is a municipality on the southern tip of Greenland, operational from 1 January 2009. The administrative center of the municipality is in Qaqortoq (formerly called Julianehåb). Creation The municipality consists of the former municipalities of southern Greenland, each named after the biggest settlement: * Nanortalik Municipality * Narsaq Municipality * Qaqortoq Municipality In addition to the area of these municipalities, uninhabited parts of the former municipalities of Paamiut and Ammassalik were added to the new administrative entity. In the case of Paamiut Municipality, it was exclusively a part of the ice sheet including a few nunataks, while in the case of Ammassalik Municipality, it included the coast from the fjord Kangerlussuatsiaq (in Danish ''Lindenow Fjord'') on the old border with Nanortalik Municipality in the south to north of Timmiarmiut.

Villiaumite
Villiaumite is a rare halide mineral composed of sodium fluoride, Na F. It is very soluble in water and some specimens fluoresce under long and short wave ultraviolet light. It has a Mohs hardness of 2.5 and is usually red, pink, or orange in color. It is toxic to humans. The red color is due to a broad absorption peaking at 512 nm. It is a result of radiation damage to the crystal. Occurrence It occurs in nepheline syenite intrusives and in nepheline syenite pegmatites. It occurs associated with aegirine, sodalite, nepheline, neptunite, lamprophyllite, pectolite, serandite, eudialyte, ussingite, chkalovite and zeolites. It has been reported from Minas Gerais, Brazil; Mont Saint-Hilaire, Quebec, Canada; the Ilimaussaq complex of Greenland; Lake Magadi, Kenya; Windhoek District, Namibia; the Fen Complex, Telemark, Norway; the Khibiny and Lovozero Massifs, Kola Peninsula, Russia; Porphyry Mountain, Boulder County, Colorado and Point of Rocks Mesa, Colfax County, New Mexi ...

Uranium Mines
Uranium production is carried out in about 13 countries around the world, in 2017 producing a cumulative total of 59,462 tonnes of uranium (tU). The international producers were Kazakhstan (39%), Canada (22%), Australia (10%), Namibia (7.1%), Niger (5.8%), Russian Federation (4.9%), Uzbekistan (4.0%), China (3.2%), United States (1.6%), Ukraine (0.9%), India (0.7%), South Africa (0.5%) and Pakistan (0.1%).

Naleraq
Naleraq (, ), previously known as Partii Naleraq, is a centrist-populist pro-independence political party in Greenland. History In January 2014 Hans Enoksen announced that he was forming a new political party after leaving Siumut. In the November 2014 general election the party won three seats, taken by Enoksen, Per Rosing-Petersen (another former Siumut member) and Anthon Frederiksen (a former Association of Candidates member). In the April 2018 general election, the party increased its vote share and won four seats in parliament. In May 2018, MP Henrik Fleischer left the party and switched to Siumut. On 15 February 2021 the party changed its name and logo. In June 2022 Hans Enoksen resigned as party chairman of the party, and was replaced by Pele Broberg Pele Broberg (born 1972) is a Greenlandic politician (Naleraq), entrepreneur and pilot.

Inuit Ataqatigiit
Inuit Ataqatigiit (, , da, Folkets Samfund) is a democratic socialist, separatist political party in Greenland that aims to make Greenland an independent state. The party, founded as a political organisation in 1976, was born out of the increased youth radicalism in Denmark during the 1970s. Traditionally in favour of a socialist economy, the party has been criticised from the left of having gradually moved towards a capitalist approach, supporting a market economy and privatisation. Inuit Ataqatigiit believes that an independent Greenland should be competitive while fighting to keep the environment clean. In 1982, the party successfully campaigned in a national referendum for Greenland to leave the European Economic Community (EEC). Inuit Ataqatigiit is represented in the Folketing (the Danish parliament) by Aaja Chemnitz Larsen. Múte B. Egede has been the party's leader since December 2018. Inuit Ataqatigiit made a major electoral breakthrough in the 2009 Greenlandic parl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-pit Mining
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting ea ...

Narsaq
Narsaq is a town in the Kujalleq municipality in southern Greenland. The name ''Narsaq'' is Kalaallisut for "Plain", referring to the shore of Tunulliarfik Fjord where the town is located. History People have lived in the area for thousands of years, but not continuously. Remains of the Norse settlement can be found in the area. The church ruins of Dyrnæs can be found on the north-western outskirts of the town. The Landnám homestead, ''Landnamsgaarden'', can be found immediately to the west of the town. Dated to the year 1000, the homestead is among the oldest of the Norse ruins in the area. Excavation of the ruins began in 1953 with the discovery of the Narsaq stick, the first Viking Age runic inscription discovered in Greenland. The wider Narsaq area has some of the most striking Norse artefacts and ruins. Erik the Red's Brattahlid is located in present-day Qassiarsuk, and the Gardar bishop seat is in present-day Igaliku. Present day Narsaq was founded as Nordprøven (" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
