Dumortierite Information. Blue, violet, brown, pinkish, blue-green, greenish. 8 - 8.5; massive varieties 7. Massive blue and violet material occurs in pieces weighing several pounds. Only a small amount of facetable material has ever been discovered (Brazil, Sri Lanka), and these gems tend to be very small (under 1-2 carats).

Chert can be of both organic (diatomite and radiolarite on ocean floors) and inorganic origins. Its formation can be due to different types of processes: (1) accumulation of siliceous oozes on the oceanic floors (diatomites and radiolarites); (2) secondary replacement of carbonate minerals (shallow marine deposits); or (3) precipitation from silica-rich hydrothermal solutions (silica sinters).

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...
Scheelite is a calcium tungstate mineral with the chemical formula Ca W O 4.It is an important ore of tungsten (wolfram).

Name: Named in 1847 by Johann Friedrich August Breithaupt for an unspecified type locality area "near" the Amazon River. A variety of Microcline. A green to blue-green variety of K-feldspar, usually microcline, but sometimes applied to orthoclase. The color is usually caused by an elevated content of Pb (up to 1.2% PbO, see list of references).
Tanzanite is the blue and violet variety of the mineral zoisite (a calcium aluminium hydroxyl sorosilicate), caused by small amounts of vanadium. Tanzanite belongs to the epidote mineral group. Tanzanite is only found in Tanzania, in a very small mining area (approximately 7 km (4.3 mi) long and 2 km (1.2 mi) wide) near the Mererani Hills.
Small amounts of salt and phosphate are mined from Barbuda and Redonda, respectively. But the main quarrying activity that takes place in Antigua and Barbuda is sand mining on the island of Barbuda. Sand mining has historically been the largest industry on the island, despite its potentially devastating side effects.
Fluorapatite, often with the alternate spelling of fluoroapatite, is a phosphate mineral with the formula Ca 5 (PO 4) 3 F (calcium fluorophosphate). Fluorapatite is a hard crystalline solid. Although samples can have various color (green, brown, blue, yellow, violet, or colorless), the pure mineral is colorless, as expected for a material lacking transition metals.
Larimar is a type of pectolite or a rock composed largely of pectolite, an acid silicate hydrate of calcium and sodium.
