The Collector S Guide To Rocks Minerals

An easy to use field guide that contains everything rock and mineral enthusiasts need to know with more than 1,000 spectacular illustrations—600 in full color! Practical, concise, and easy to use, Simon & Schuster’s Guide to Rocks and Minerals contains everything that the rock and mineral enthusiast needs to know. This field guide is divided into two large sections—one devoted to minerals and one to rocks, each prefaced by a comprehensive introduction that discusses formation, chemistry, and more. All 377 entries, beautifully illustrated with color photographs and helpful visual symbols, provide descriptions and practical information about appearance, classification, rarity, crystal formation, mode of occurrence, gravity of mineral, rock chemistry, modal classification fields, formational environments, grain sizes of rocks, and much more. Whether you are a serious collector or an information-seeking amateur, this incomparably beautiful, authoritative guide will prove an invaluable reference.

With the tremendous growth of population in this and neighboring states, there are more collectors than ever before and with the rapidly escalating prices for mineral and fossil specimens in the retail market, there is a great demand for displayable material. It has become necessary for professional geologists, hobby collectors, and commercial collectors to recognize each others existence and to try to work together within a framework of regulation, courtesy, and common sense so that material of scientific value is not lost and undue restrictions are not placed upon collecting. There is a continuing need for collectors and professionals to work together with resource managers and legislators to develop workable laws and rules affecting the collecting of minerals and fossils. This publication contains details information about collecting areas, divided by county to make for ease of use. Each collecting area contains information about the minerals, rocks, or fossils present, map recommendations, and other helpful tips on getting to the sites.

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?

Garnet, with its many color varieties, is a favorite of both mineral collectors and gemologists. Superb examples are found at many locales worldwide, in both igneous and metamorphic rocks. Other members of the group are prized by species collectors and micromount enthusiasts. Over 120 color photos of these beautiful minerals show each species in its geological context. This book also explains how garnets are formed and the unique conditions that create fine crystals 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 garnets 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.

Describes hundreds of minerals and lists their geographic distribution, physical properties, chemical composition, and crystalline structure.
