Rockhound and Prospector's Bible: A Reference and Study Guide to Rocks, Minerals, Gemstones and Prospecting

This book contains data on the mineral deposits themselves, broken down by magmatic, hydrothermal, secondary and placer deposits, as well as gemstones. Determinative tables, specific geologic environment references and a glossary round out this book. This Bible should appeal to the reader who wants a deeper understanding of geologic processes.

-----------------------------
I have no hesitation recommending this most useful "Bible" to all students of gemology. Not only will you enjoy reading this book, you will be amazed at what you will learn about the practical aspects of mineral identification, with the assistance of the Determinative Tables and the listing of Geologic Environments of Minerals. Its purchase is highly recommended for students. Len Ettinger's more than decades of expertise in exploration geology is obvious. This is indeed a book to teach the practically applicable basics of field mineral identification and prospecting techniques.

-----------------------------
The Rockhound and Prospector's Bible is more than just a basic text for the gold-panner or rockhound. It is actually a study guide which begins by giving the reader a general introduction to Geology. This detailed, yet simple to understand volume is recommended for those who are interested in how mineral and gems came to be, rather than just giving directions to sites where they can be located.
