Over the last several decades, the number of people who are actively involved in the hobby or science of mineral collecting has grown at an increasing pace. In response to the growing demand for informa tion which this large and active group has created, a number of books have been published dealing with mineralogy. As a result, the reader now has a choice among mineral locality guides, field handbooks, photo collections, or books dedicated to the systematic description of minerals. However, as interest in mineralogy has grown, as collectors have become increasingly knowledgeable and aware of mineralogy in its many facets, the need for more specialized information has also grown. Nowhere is this need greater than in the subject of the fluorescence of minerals. The number of collectors who now main tain a fluorescent collection is substantial, interest is constantly increasing, and manufacturers have recently responded by the intro duction of new ultraviolet equipment with major improvements in utility and performance. Yet when the collector searches for any information on this subject, little will be found. He or she will seek in vain for the answers to questions which present themselves as in terest in fluorescent minerals grows and matures. Which minerals fluoresce? Where are fluorescent minerals found? What makes a mineral fluoresce? Why does ultraviolet light produce fluorescence? What is an activator, and how does it contribute to fluorescence? On these matters, the available mineralogy books are largely silent.

A sweeping survey of the fluorescent minerals of the world shown both in daylight and under the ultraviolet light. Written for the collector and the merely curious, this pictorial reference will capture your attention with its 825 color photos and informative text. It is an essential source for enjoying and identifying fluorescent minerals.

Revised and Expanded 2nd Edition. Seeing fluorescent minerals up close for the first time is an exciting experience. The colors are so pure and the glow is so seemingly unnatural, that it is hard to believe they are natural rocks. Hundreds of glowing minerals are shown, including Aragonite, Celestine, Feldspar, Microcline, Picropharmacolite, Quartz, Spinel, Smithsonite, plus many more. But dont let the hard-to-pronounce names keep you away. Over 870 beautiful color photographs illustrate how fluorescent minerals look under UV light and in daylight, making this an invaluable field guide.Here are minerals from the United States, including mines in New Jersey, New York, Arizona, and California, as well as beautiful and unusual minerals from Canada, Mexico, Greenland, Italy, Sweden, and other places. Included are values, a comprehensive resources section, plus helpful advice on caring for, collecting, and displaying minerals. The field of collecting fluorescent minerals is relatively new and this is one of the most complete references available.

This book provides information on the nature of ultraviolet light, how it causes fluorescence, and mineral fluorescence as a hobby. Also included are discussions of major fluorescent minerals and mineral groups and techniques for collecting them.

The complete source for understanding and locating fluorescent minerals. Documents all major locations in the U.S. and throughout the world. One of very few publications on this subject. Includes experiments for home and school use.

From the author of "Minerals of Arizona-a Field Guide for Collectors", comes a second field guide for Arizona collectors. This is not an updated version of "Minerals of Arizona", but an entirely new, expanded field guide designed for not only the mineral collector, but for fossil and fluorescent collectors as well. No other Arizona rockhound book contains special independent sctions on fossils and fluorescents. The field research for this work took over 3 years during which the author traveled over 25,000 miles across Arizona and visited over 300 potential collecting sites. To aide the collector, Minerals, Fossils, and Fluorescents includes: - 90 collecting sites complete with site photographs and National Geographic Topo! (C) maps. - Global positioning system coordinates for each location. - A difficulty scale informing the reader of the effort required to reach, navigate, and collect at each site. - chapters covering the basic science of the minerals, fossils, and fluorescents to be collected. - The geological formations at each site and the scientific properties of the speimens found there. - 20 pages of full color photographs of specimens by the well-known mineral photographer Jeffrey Scovil including 5 pages of fluorescent minerals. - Over 400 pages of text, maps, and collecting site and specimen photographs.
