Mineral Specimen

This learner-oriented text is written in a casual, jargon-free style to present a modern introduction to mineralogy. It emphasizes real-world applications and an “ outside-in approach” as well as the history and human side of mineralogy. Chapter topics include elements and minerals; crystallization and classification of minerals; mineral properties: hand specimen mineralogy; optical mineralogy; igneous rocks and silicate minerals; sedimentary minerals and sedimentary rocks; metamorphic minerals and metamorphic rocks; ore deposits and economic minerals; crystal morphology and symmetry; crystallography; units cells, points, lines, and planes; x-ray diffraction; atomic structure; and descriptions of minerals. For individuals interested in the science of mineralogy, and how minerals impact everyday life.

A detailed and extensively illustrated handbook. The colors, shapes and properties of minerals vary from the bland to the magnificent. Guide to Minerals, Rocks and Fossils is a practical and authoritative handbook that is both comprehensive and easy to use. Each of the 600 specimens is shown in full color, sometimes in two or more forms. There are also drawings that show the structure of the crystalline specimens. It covers the basics like granite, as well as oddities like meteorites and tektites. Fossils include sponges, corals, arthropods, brachiopods, and fossil land plants. Each is described in detail, with notes on: - color and transparency - grain size - hardness - structure - occurrence - mineralogy - distinguishing features - habit - cleavage - texture - alteration - luster Mineral names, chemical formulae and structural data accord to international standards. This is a very complete, but attractive and useful volume in a respected series.

Micromount - Micromount is term used by mineral collectors and rockhounds to describe mineral specimens that are best appreciated using optical aid, commonly a binocular microscope. Micromount specimen collecting has a number of advantages, specimens take up less space, rare minerals can be obtained for less and smaller crystals are more perfectly developed.

Hopeite - Hopeite is a hydrated zinc phosphate with formula: Zn3(PO4)2Â·4H2O. It is a rare mineral used mainly as a collectors specimen.

Tucson Gem & Mineral Show - The Tucson Gem & Mineral Show is held every year in February for three weeks (two open to the public, one open only to professionals). It is one of the largest and most well-known gem and mineral shows anywhere, and it features the many of the finest mineral specimens available.

Lake Mineral Wells State Park & Trailway - Lake Mineral Wells State Park & Trailway is a state park located in Mineral Wells, Parker County, Texas. It includes Lake Mineral Wells, and is the only state park in Texas which protects part of the Western Cross Timbers.

Ekanite is almost invariably found completely metamict as thorium and uranium are part of its essential chemical composition. Further, metamictization diffuses the bands of a metamict mineral is zircon. The presence of the uranium mineral coffinite and the thorium mineral thorite are responsible for degrading a mineral's absorption spectrum. All metamict materials are themselves radioactive, some dangerously so. Certain minerals occasionally contain interstitial impurities of radioactive compounds and it is the alpha radiation emitted from these compounds that is responsible for degrading a mineral's refractive index, hardness, and specific gravity. Metamict minerals can have their crystallinity and properties restored through prolonged annealing. Metamictization Metamictization is a natural process resulting in the gradual and ultimately complete destruction of a mineral's crystal structure through internal bombardment.
