List of minerals: Gallium Pentlandite Pentlandite Cinnabar Germanium Chromite Quartz/silica Hematite Hematite Hematite Galena Common uses for these minerals: Cinnabar is an ore of mercury and is used in thermometers. Gallium is a soft, silvery metal used mainly in electronic circuits, semiconductors and light-emitting diodes (LEDs). It is also useful in high-temperature thermometers, barometers, pharmaceuticals and nuclear medicine tests. Germanium's largest use is in the semiconductor industry. When doped with small amounts of arsenic, gallium, indium, antimony or phosphorus, germanium is used to make transistors for use in electronic devices. Germanium is also used to create alloys and as a phosphor in fluorescent lamps. Hematite is the most important ore of iron. It is used in steel components and in many products such as building materials, cars and mostly anything containing metal. Pentlandite is an ore of nickel. It’s most common use is in the production of stainless steel, like in sinks and cutlery, but is also an important alloy to make other metals stronger or more heat resistant.. Chromite is used on handles, buttons and other chrome plated components. Galena, also called lead glance, is the ore of lead. It is used in weights for lifting and diving, in solder for electronic components, in components used to store energy, and most importantly in car batteries. Quartz/silica is mainly used in glass, but it is also used in construction, ceramics as well as many other things. 2 Sciencenorth.ca/teachers Science North is an agency of the Government of Ontario and a registered charity #10796 2979 RR0001. .

MINERALS SORTED BY NAME Here is an alphabetical list of minerals discussed on this site. More information on and photographs of these minerals in Kentucky is available in the book “Rocks and Minerals of Kentucky” (Anderson, 1994). APATITE Crystal system: hexagonal. Fracture: conchoidal. Color: red, brown, white. Hardness: 5.0. Luster: opaque or semitransparent. Specific gravity: 3.1. Apatite, also called cellophane, occurs in peridotites in eastern and western Kentucky. A microcrystalline variety of collophane found in northern Woodford County is dark reddish brown, porous, and occurs in phosphatic beds, lenses, and nodules in the Tanglewood Member of the Lexington Limestone. Some fossils in the Tanglewood Member are coated with phosphate. Beds are generally very thin, but occasionally several feet thick. The Woodford County phosphate beds were mined during the early 1900s near Wallace, Ky. BARITE Crystal system: orthorhombic. Cleavage: often in groups of platy or tabular crystals. Color: usually white, but may be light shades of blue, brown, yellow, or red. Hardness: 3.0 to 3.5. Streak: white. Luster: vitreous to pearly. Specific gravity: 4.5. Tenacity: brittle. Uses: in heavy muds in oil-well drilling, to increase brilliance in the glass-making industry, as filler for paper, cosmetics, textiles, linoleum, rubber goods, paints. Barite generally occurs in a white massive variety (often appearing earthy when weathered), although some clear to bluish, bladed barite crystals have been observed in several vein deposits in central Kentucky, and commonly occurs as a solid solution series with celestite where barium and strontium can substitute for each other. Various nodular zones have been observed in Silurian–Devonian rocks in east-central Kentucky.

Petrology of Ore Deposits
Petrology of Ore Deposits An Introduction to Economic Geology Introductory Definitions Ore: a metalliferous mineral, or aggregate mixed with gangue that can me mined for a profit Gangue: associated minerals in ore deposit that have little or no value. Protore: initial non-economic concentration of metalliferous minerals that may be economic if altered by weathering (Supergene enrichment) or hydrothermal alteration Economic Considerations Grade: the concentration of a metal in an ore body is usually expressed as a weight % or ppm. The process of determining the grade is termed “assaying” Cut-off grade: after all economic and political considerations are weighed this is the lowest permissible grade that will mined. This may change over time. Example Economic Trends Economy of Scale As ore deposits are mined the high-grade zones are developed first leaving low-grade ores for the future with hopefully better technology Since mining proceeds to progressively lower grades the scale of mining increases because the amount of tonnage processed increases to remove the same amount of metal Outputs of 40,000 metric tons per day are not uncommon Near-surface open pit mines are inherently cheaper than underground mines Other factors important to mining costs include transportation, labor, power, equipment and taxation costs Classification of Ore bodies Proved ore: ore body is so thoroughly studied and understood that we can be certain of its geometry, average grade, tonnage yield, etc. Probable ore: ore body is somewhat delineated by surface mapping and some drilling. The geologists is reasonably sure of geometry and average grade. Possible Ore: outside exploration zones the geologist may speculate that the body extends some distance outside the probable zone but this is not supported by direct mapping or drilling.

The Anjahamiary Pegmatite, Fort Dauphin Area, Madagascar
The Anjahamiary pegmatite, Fort Dauphin area, Madagascar Federico Pezzotta* & Marc Jobin** * Museo Civico di Storia Naturale, Corso Venezia 55, I-20121 Milano, Italy. ** SOMEMA, BP 6018, Antananarivo 101, Madagascar. E-mail:<[email protected]> 21 February, 2003 INTRODUCTION Madagascar is among the most important areas in the world for the production, mainly in the past, of tourmaline (elbaite and liddicoatite) gemstones and mineral specimens. A large literature database documents the presence of a number of pegmatites rich in elbaite and liddicoatite. The pegmatites are mainly concentrated in central Madagascar, in a region including, from north to south, the areas of Tsiroanomandidy, Itasy, Antsirabe-Betafo, Ambositra, Ambatofinandrahana, Mandosonoro, Ikalamavony, Fenoarivo and Fianarantsoa (e.g. Pezzotta, 2001). In general, outside this large area, elbaite-liddicoatite-bearing pegmatites are rare and only minor discoveries have been made in the past. Nevertheless, some recent work made by the Malagasy company SOMEMEA, discovered a great potential for elbaite-liddicoatite gemstones and mineral specimens in a large, unusual pegmatite (the Anjahamiary pegmatite), hosted in high- metamorphic terrains. The Anjahamiary pegmatite lies in the Fort Dauphin (Tôlanaro) area, close to the southern coast of Madagascar. This paper reports a general description of this locality, and some preliminary results of the analytical studies of the accessory minerals collected at the mine. Among the most important analytical results is the presence of gemmy blue liddicoatite crystals with a very high Ca content, indicating the presence in this tourmaline crystal of composition near the liddicoatite end-member. LOCATION AND ACCESS The Anjahamiary pegmatite is located about 70 km NW of the town of Fort Dauphin (Tôlanaro) (Fig.

The New IMA List of Gem Materials – a Work in Progress – Updated: July 2018
The New IMA List of Gem Materials – A Work in Progress – Updated: July 2018 In the following pages of this document a comprehensive list of gem materials is presented. The list is distributed (for terms and conditions see below) via the web site of the Commission on Gem Materials of the International Mineralogical Association. The list will be updated on a regular basis. Mineral names and formulae are from the IMA List of Minerals: http://nrmima.nrm.se//IMA_Master_List_%282016-07%29.pdf. Where there is a discrepancy the IMA List of Minerals will take precedence. Explanation of column headings: IMA status: A = approved (it applies to minerals approved after the establishment of the IMA in 1958); G = grandfathered (it applies to minerals discovered before the birth of IMA, and generally considered as valid species); Rd = redefined (it applies to existing minerals which were redefined during the IMA era); Rn = renamed (it applies to existing minerals which were renamed during the IMA era); Q = questionable (it applies to poorly characterized minerals, whose validity could be doubtful). Gem material name: minerals are normal text; non-minerals are bold; rocks are all caps; organics and glasses are italicized. Caveat (IMPORTANT): inevitably there will be mistakes in a list of this type. We will be grateful to all those who will point out errors of any kind, including typos. Please email your corrections to [email protected]. Acknowledgments: The following persons, listed in alphabetic order, gave their contribution to the building and the update of the IMA List of Minerals: Vladimir Bermanec, Emmanuel Fritsch, Lee A.
