Minerals Justin Rule, Jenna Gordon, Steven Weber Amphibole (Hornblende) Cleavage, colour Decoration Apatite Colour, crystal shape, hardness Fertilizer Asbestos Fibrous, colour, waxy lustre. Used in insulation, proven to lead to lung cancer Azurite Colour Decoration, gemstones Bornite Colour Ore of copper Calcite Acid reactivity Antacid Chalcopyrite Colour, streak, softer than pyrite Ore of copper Chlorite Colour, hardness Construction filler, very few practical uses Feldspar (plagioclase) Cleavage Decoration Feldspar (Orthoclase) Cleavage, colour Gemstones Fluorite: Has a glassy luster and makes cube like crystals and 4 excellent, octahedral. Fluorite is used instead of glass in some high performance telescopes and camera lens elements. Galena: Color is lead-gray, has cubes or massive and 3 perfect at 90° cleavage. Galena is the most important ore of lead. Silver is often produced as a by-product. Garnet: It’s a glassy lustre, 12 or 24 faced crystals and has a hardness of 7. Garnet uses include: gemstone, sand paper. Gold: It has a Gold yellow color, streak that is yellow, and crystal form of flakes, grains, massive Most of the gold that is newly consumed or recycled each year is used in the production of jewelry. Graphite Graphite has a metallic lustre and a silver colour. Pencil lead, oil, lubricant. Or lead ores. Gypsum Clear or white minerals with a glassy or vitreous lustre. Used as drywall. Halite White or Colourless and a vitreous lustre Table salt, tanning. Hematite Limonite metallic silver lustre and a and earthy Iron ore A brown to yellow colour and a earthy tone Iron ore Magnetite Matallic lustre and a black colour Is one of the minerals that make up a iron ore. Is one of the only magnetic minerals. Malachite Malachite has a vibrant green colour with a pearly look. Is a copper ore, which makes its uses far more advanced Mica Muscovite Biotite Muscovite has a white/pink even a translucent colour and a glassy/vitreous lustre Biotite has a silver/black colour and a metallic/glassy lustre Mica can be used as a insulator for high voltage electrical work Muscovite can also used as a see through glass type in high heat machines Molybdenite Molybdenite has a bluish silver look with a metallic lustre and a flaky form Molybdenite is the only mineral that makes a molybdenum ore. The ore can be made into a lubricant Olivine Olivine is named after its olive green colour. It has a vitreous lustre and white streak. Olivine is commonly used in jewellery, brinks, and refractory sand. Pyrite Pyrite has a brassy yellow colour and a metallic lustre. It has a cubic crystal form as well. The creating of a chemical for the paper industry and a acid for the chemical industry. Although it as a iron ore because of the acid it makes it useless in most businesses Pyroxene (augite) Pyroxene has a dark green to black colour with a vitreous lustre. Pyroxene is used to manufacture for lithium salts and glasses. Pyrrhotite Pyrrhotite has a bronze and yellow look with a black streak and a metallic lustre Pyrrhotite is commonly used as a iron ore Quartz Family The quartz has a arrangement of colours and a vitreous lustre and can have a prismatic crystals. Most commonly used as a gemstones in jewellery. Sphalerite Sphalerite has a brown/yellow colouring with a metallic and resinous lustre Its main uses were that it has a zinc ore. Talc Talc has a pearly white colouring and a waxy lustre; it is also a very soft mineral. Talc is most commonly used in paint. http://www.soes.soton.ac.uk/resources/collection/minerals/minerals/pages/M34-Amph.htm http://www.prettyrock.com/php/facet-rough-variety-blue-apatite.php http://www.mesotheliomatreatmentcenters.org/asbestos-pictures/fibers/ http://www.learnearthscience.com/pages/Unit_Links/mineral_images.htm www.crystal-cure.com/azurite.html http://www.galleries.com/minerals/sulfides/bornite/bornite.htm http://www.learnearthscience.com/pages/Unit_Links/mineral_images.htm http://gwydir.demon.co.uk/jo/minerals/alphabet.htm http://www.beg.utexas.edu/mainweb/publications/graphics/calcite.htm http://geology.com/minerals/chlorite.shtml http://www.choudhery.com/export/graphite.jpg http://goldpricetrend.com/images/gold_price_trend1.jpg http://www.cs.cmu.edu/~adg/images/minerals/pygarnets/garnet_xtalpr.jpg http://webmineral.com/specimens/photos/Galena.jpg http://www.palagems.com/Images/mineral_news/featured_fluorite.jpg http://www.geology.com
