Paperback. Condición: new. Paperback. The axinite group of rock-formed minerals is well known to collectors through the spectacularly sharp crystals collected in quantity at Dal'negorsk and Puiva in Russia and at Tomas and other localities in Pakistan. Axinites are occasionally cut as gems. This concise monograph provides an up-to-date review of the group, incorporating recent changes to the names of three axinite species. The book is illustrated with over 90 full-color photographs of representative specimens. After a brief introduction, the text provides an explanation of the chemistry and taxonomy of the group and an illustration of the crystal structure and morphologies of real crystals. Detailed entries for each mineral provide information on notable localities and full-color photos wherever possible, so that readers can see what good specimens look like and which minerals one might expect to find in association with axinites. This book is a must for mineral collectors everywhere.

Paperback. Condición: new. Paperback. Among rock-forming minerals, the vesuvianite group is best known through the many colorful crystals collected at the Jeffrey quarry, in Asbestos, Canada. Spectacular finds in China and Pakistan have added interest in this mineral group. The detailed text begins with an explanation of the chemistry and taxonomy of the group and a discussion of ongoing research into problems such as color, structure, and optically anomalous crystals. A section on their formation and geochemistry explains the kinds of environments where vesuvianites are formed. Each mineral has a detailed entry for information on important localities. Over 90 full-color photos show what good specimens look like and which minerals to expect to find associated with vesuvianites. Anyone with a passion for minerals will find this book fascinating.

Paperback. Condición: new. Paperback. Mica is a broad term encompassing about forty minerals, ranging from the common to the rare, many at times forming excellent crystals jewelers use. This book feaures examples recently described among the 115 striking color photos and electron micrographs that illustrate the text. A detailed entry for each type includes information on where each is found, associations of micas with other minerals, pseudomorphs (minerals that masquerade as mica), and micas that fluoresce under UV light. This fascinating guide is for those interested in minerals. AUTHOR: Robert Lauf is a scientist holding a Ph.D. in Metallurgical Engineering.

Paperback. Condición: new. Paperback. Among rock-forming minerals, the colorful tourmaline group is a favorite of both mineral collectors and gemologists. Superb examples are found at many locales worldwide, and in diverse geological settings from pegmatites to schists. Over 120 clear, crisp photos show each mineral in its geological context. This book will help mineral and gem collectors understand tourmaline mineralogy and see how changes in nomenclature reflect our evolving understanding of the group. The text explains the chemistry and taxonomy of the group, the environment in which tourmalines form, provides a detailed entry for each mineral including locality information and full-color photos wherever possible 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 readers who wish to learn more. Every serious mineralogist, gemologist, and rock hound will need this book. AUTHOR: Robert J.

Paperback. Condición: new. Paperback. Quartz is prized by both mineral collectors and lapidary artists. Over 130 vivid photographs of these beautiful minerals are presented to show each mineral in its geological context. Superb examples are found in diverse geological settings from pegmatites to Alpine clefts and hydrothermal veins. The silica minerals are chemically simple, yet structurally complicated. Several high temperature and high pressure polymorphs are known. In addition to the polymorphs of silica, this book treats related minerals, including: lechatelierite, opal, and two natural clathrates, chibaite and melanophlogite. After a brief introduction, the general treatment explains the chemistry and taxonomy of the group. A section on their formation and geochemistry describes the kinds of environments where these minerals are formed. Then, 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 also provided. AUTHOR: The author holds a Ph.D. in Metallurgical Engineering, and has conducted scientific research in fields ranging from nuclear fuel to microwave processing and biomineralization. He has been granted over 40 U.S. Patents, and has written 10 books on mineralogy for collectors. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.

Paperback. Condición: new. Paperback. The amphibole group is extremely important, widespread, and beautiful, with a structure that can accommodate a bewildering variety of compositions and potentially hundreds of unique specimens. This timely volume will allow mineral collectors to understand how the amphiboles are organized and named, and to relate obsolete names to currently accepted ones. Over 140 full-colour crystal images help the reader visualize the important structural features that define amphiboles and control their physical properties. This reference also provides information that collectors need to know to better understand the group and to learn what the specimens teach us about geological processes. Structural chemistry and taxonomy of the group is explored as well as formation and geochemistry, explaining the kinds of environments where amphiboles are formed. An entry for each mineral series provides locality information along with identification photos wherever possible, and examples that one might expect to find in the varied locales. AUTHOR: The author holds a Ph.D. in Metallurgical Engineering from the University of Illinois. His scientific career included over twenty years at Oak Ridge National Laboratory, where he conducted research on topics ranging from nuclear fuel, coal by-products, materials synthesis, and microwave processing to sensors, optical materials, and biomineralization. He has been granted over forty U.S. Patents for his inventions, many of which have become successful industrial products. He is now a Registered Patent Agent and technology consultant. 144 colour photographs Shipping may be from multiple locations in the US or from the UK, depending on stock availability.
