8. Maine Geology - Maine's State Mineral, Tourmaline MAINE DEPARTMENT OF CONSERVATION Maine Geological Survey one of the most attractive minerals occurring in Individual crystals range from opaque to transparent http://www.state.me.us/doc/nrimc/pubedinf/factsht/bedrock/stminral.htm

State Agencies Web Policies My Maine.gov Email this page MAINE DEPARTMENT OF CONSERVATION Maine Geological Survey Tourmaline: Maine's State Mineral Tourmaline is one of the most attractive minerals occurring in Maine. It ranges in color from black or white to vibrant shades of red, green, and blue. The color of the best Maine specimens rivals that of tourmaline from world-famous localities in California, Brazil, and the Himalayas. Individual crystals range from opaque to transparent and may be single or multi-colored. There is even a "watermelon" variety with a green outer layer surrounding a pink core. Transparent crystals that are clear enough to yield faceted gemstones are highly prized, while lesser grades of this durable mineral are tumble-polished for use in various kinds of jewelry. Well-formed tourmaline crystals in their natural state are also sought by mineral collectors. TOURMALINE DISCOVERIES IN MAINE The first major tourmaline discovery in Maine occurred in 1820 at Mount Mica in Paris. The famous story of the discovery by two boys exploring the local countryside was related by Augustus Hamlin in his 1895 book entitled "The History of Mount Mica". A quarry that was opened at the site has intermittently produced gem tourmaline and other interesting minerals up to the present day. The Hamlin Necklace, containing fine tourmalines of various colors from this quarry, can be seen in the Harvard University Mineralogical Museum. Many other tourmaline deposits have been found in Maine over the years. Sharp crystals of black tourmaline are widespread in pegmatites of Oxford, Androscoggin, Sagadahoc, and Cumberland Counties. The colored crystals occur mainly in Oxford County and the Auburn-Poland area. It is curious that the best gem-producing localities lie on a straight line extending southeastward through this part of the state. In 1972 a spectacular series of large tourmaline pockets was opened at the Dunton Mine in Newry. Hundreds of pounds of red and green crystals were found, including the "Jolly Green Giant", a 10-inch crystal now in the collection of the National Museum of Natural History in Washington, D.C. The State of Maine tourmaline necklace was designed using Newry gems and presented to the State in 1975 by the Maine Retail Jewelers Association. (The chain of this necklace was made from gold nuggets panned from the Swift River in Byron.)

State Agencies Web Policies My Maine.gov Email this page MAINE DEPARTMENT OF CONSERVATION Maine Geological Survey Mineral Collecting Maine has an excellent reputation among "rockhounds" for the variety and quality of mineral specimens found within its borders. Hundreds of people explore the state each year in search of crystals, semiprecious gems, gold, and other minerals. The novice is practically assured of finding something of interest at Maine's collecting sites, while a large assortment of rare minerals await the advanced collector. Mineral collecting is an inexpensive hobby that can be enjoyed by all age groups, and offers the fringe benefits of outdoor recreation and the opportunity to learn about earth science. Many of the best minerals in Maine are found in an igneous rock called "pegmatite", which is a very coarse-grained granite. Some pegmatites are enriched in uncommon minerals such as beryl, topaz, and colored tourmaline; they may also contain very rare species or large crystals of various minerals. Pegmatite veins are abundant in parts of Oxford, Androscoggin, and Sagadahoc Counties. Most of them were commercially worked for mica or feldspar, creating piles of waste rock ("dumps") where collectors search for specimens. Road cuts and natural outcrops of other rock types occasionally provide good mineral specimens. This is particularly true of coarse-grained metamorphic rocks produced by the deep burial and recrystallization of ancient marine sediments. Examples of metamorphic mineral occurrences include the kyanite and staurolite crystals in mica schist at Windham, garnet crystals in schist and calcium-rich rocks at numerous places, and vesuvianite crystals in Sanford.

For Example, the Mexican deposits of Amethyst are lighter, while samples from Brazil can reach a deep purple color. Even though they are the same basic stone, slight variations in the chemical composition of each result in a unique crystal. Even samples from the same mine can appear quite different; it all depends on the elements that are present at the time of the crystal's development.

University of Colorado GEOLOGY 1010 Class Note 3 Minerals and Rocks A mineral is a naturally occurring homogeneous solid of definite chemical composition and ordered atomic arrangement. It is usually formed by inorganic processes. More than 5000 mineral species have been described and more than 100 new minerals are described every year. To describe a new mineral, the structure and composition must be described. Most of these 5000 minerals are rare, so that only about 200 are common enough to make up macroscopic rocks. Of these, the most abundant 50 make up 99.9% of the Earth's crust. Some examples of minerals that are familiar to you are quartz (SiO , silicon dioxide), calcite (CaCO calcium carbonate), pyrite (FeS , iron sulfide), gypsum (CaSO . 2 H O), gold (Au), silver (Ag), copper (Cu), diamond (C), graphite (C), garnet (Mg Al Si O ice (H O). Less familiar, perhaps, are apatite (Ca (PO OH) (teeth and bone), olivine (Mg SiO ) (the green mineral that makes up much of the upper mantle, gem variety: peridot), pyroxene (MgSiO ) (the other mineral in the upper mantle), muscovite (white)

Nelson Tulane University T he Earth is composed of rocks. Rocks are aggregates of minerals. Minerals are composed of atoms . In order to understand rocks, we must first have an understanding of minerals. In order to understand minerals we must have some basic understanding of atoms - what they are and how they interact with one another to form minerals. top... Definition of a Mineral Naturally formed it forms in nature on its own (some say without the aid of humans] Generally a solid (though oil, gas...are also considered minerals in the economic sense) With a definite chemical composition (every time we see the same mineral it has the same chemical composition that can be expressed by a chemical formula). and a characteristic crystalline structure (atoms are arranged within the mineral in a specific ordered manner).

Thus, glass is not a mineral.
