Download or read book Collector s Guide to the Feldspar Group written by R. J. Lauf and published by Schiffer Earth Science Monogra. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 100 vivid color photographs of beautiful feldspar minerals show each species in its geological context. The feldspar minerals, as a group, make up nearly sixty percent of the earth's crust. Large crystals are found at many locales worldwide, in both igneous and metamorphic rocks. Often, feldspar forms the matrix for stunning gem crystals found in pegmatites. This book explains how feldspars are formed and the complicated structural features that create fine crystals, twins, and vivid colors. After a brief introduction, the general treatment begins with an explanation of the chemistry and taxonomy of the group. A section on their formation and geochemistry explains the kinds of environments where feldspars are formed. Detailed entries for each mineral provide locality information and full-color photos so that collectors can see what good specimens look like and which minerals one might expect to find in association with them. An extensive bibliography is provided for further study.

Download or read book The Collector s Guide to the Minerals of New York State written by Steven C. Chamberlain and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continuing a tradition that began in 1842, this book examines 24 localities of particular interest to mineral collectors. These localities are organized by how they occur (in sedimentary rocks, in crystalline rocks, in fractures)—a new approach that brings coherence to relationships among similar localities. For each locality, its significance to specimen mineralogy, collecting history, geological setting, origin, and a thorough description of the minerals of particular interest to collectors are presented, based on the latest research and nomenclature. Over 150 clear color photos show some of the finest specimens ever collected from each locality. Similar New York state localities are listed for each featured occurrence. While the GPS coordinates for each locality are provided, this is an introduction to what minerals occur in the State of New York, how beautiful they are, and why they are so interesting. Why have a mere field guide when you can have so much more?

Download or read book The Collector s Book of Fluorescent Minerals written by Manuel A. Robbins and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
