Abstract Rare earth elements belong to the category of strategic metals. The largest deposits of these strategic raw materials are associated with alkali-carbonatite formations. The largest alkali-carbonatite complexes of the world are located on the Kola Peninsula and in Polar Siberia. These complexes have great potential for strategic raw materials, including rare earths. The purpose of this ...

Eudialyte, whose name derives from the Greek phrase Εὖ διάλυτος, eu dialytos, meaning "well decomposable", is a somewhat rare, nine member ring cyclosilicate mineral, which forms in alkaline igneous rocks, such as nepheline syenites. Its name alludes to its ready solubility in acid.[1][3] Eudialyte was first described in 1819 for an ...

Aqualite, a new eudialyte-group mineral from hydrothermally altered peralkaline pegmatites of the Inagli alkaline pluton (Sakha-Yakutia, Russia) is described in this paper. Natrolite, microcline, eckermanite, aegirine, batisite, innelite, lorezenite, thorite, and galena are associated minerals. Aqualite occurs as isometric crystals up to 3-cm across. The color is pale pink, with a white streak ...

Uranium analyses by the fission-track method on eudialytes from the undersaturated rocks of the Ilímaussaq intrusion demonstrate that uranium enters eudialyte in isomorphous substitution. The content of uranium in the eudialytes varies with the crystallization of the magma in two ways. In the downwards-crystallizing roof rocks, eudialyte is interstitial and the content of uranium in eudialyte ...

Mineral industry of Mauritius. The mineral industry of Mauritius is small; the country does not play a significant role in the world's production or consumption of minerals. As of 2006, Mauritius produced basalt for construction, fertilizers, lime from coral, semi-manufactured steel, and solar-evaporate l sea salt.

Phenakite or phenacite is a fairly rare nesosilicate mineral consisting of beryllium orthosilicate, Be 2 Si O 4.Occasionally used as a gemstone, phenakite occurs as isolated crystals, which are rhombohedral with parallel-faced hemihedrism, and are either lenticular or prismatic in habit: the lenticular habit is determined by the development of faces of several obtuse rhombohedra and the...
Land mine contamination in Bosnia and Herzegovina is a serious after effect of the Bosnian War which raged from 1992 until 1995. During this time period, all 3 conflicting factions (ARBiH, HVO, and VRS) have planted land mines near the current-day political entity borders, and as a result the country has had the most severe land mine problems in the world.
Mining in North Korea is important to the country's economy. North Korea is naturally abundant in metals such as magnesite, zinc, tungsten, and iron; with magnesite resources of 6 billion tonnes (second largest in the world), particularly in the North and South Hamgyong Province and Chagang Province.However, often these cannot be mined due to the acute shortage of electricity in the country...
