Book Description
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.

Book Description
Tourmaline group minerals have graced the cabinets of mineral collectors and museums for untold generations. Their colors and color patterns, along with their diverse shapes and associations, have assured their role as exqui site showpieces. Their workability and durability have, in addition, made them favorites among connoisseurs of colored gemstones. Tourmalines, however, are much more than exquisite showpieces and beautiful gemstones. Their diverse crystal forms and unique structure, their variable chemical compositions, their intriguing physical properties, and their widespread occurrence in nearly all kinds of rocks have long attracted the attention of scientists from several disciplines. Furthermore, they have several potential uses in science and industry. From an historical standpoint: Tourmaline is possibly the "Lyngurium" -green at one end, light colored at the other-that Theophrastus (ca.315 B.C.) described in On Stones, the first known book about minerals. Tourma line is one of the minerals thought to have been used as a "sunstone" navigation compass by Vikings during the eighth, ninth, and tenth centuries.

Book Description
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.

Book Description
Granite pegmatite crystals have long been admired by gem and mineral collectors as a source of fine specimens and gem materials. Pegmatites can host important deposits of ore minerals and industrial commodities, such as feldspar and mica. Their physical and chemical complexity presents daunting challenges to researchers who seek to better understand their nature and origins. With 209 stunning color photos and clear, authoritative text, this book provides a thorough discussion. Chapters cover pegmatite forms and distributions, interior structures, crystal, mineral, and gem pockets, and references for further study. Examples are from North America as well as worldwide.

Book Description
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.

Book Description
Over 140 color photos, diagrams, and text reveal the crystal structures, habits, names, and changing family relationships of silicate crystals. This thorough guide provides an introduction to crystallography, the current classification of silicate structures, and reviews orthosilicates, disilicates, chain silicates, sheet silicates, and framework silicates. Explore different ways the silicate tetrahedron can be arranged and great diversity of structures that result. Crystal structure is presented with drawings of ideal crystal forms and photographs of real crystals. In this way, mineral collectors can better understand the interplay between atomic arrangements and external habits, and ultimately develop an eye for recognizing crystal symmetry. This book is a must for all serious collectors of minerals.

Book Description
Among rock-forming minerals, the zeolite group is large and widespread, and is enormously important to industry. Zeolites form excellent crystals. The group is structurally complex and notable for its ability to exchange cations with surrounding solutions. Numerous diagrams help visualize important structural features that define various framework types. Over 200 photographs of these beautiful minerals show each species in its geological context. After a brief introduction, the general treatment of the subject begins with an explanation of the structural chemistry and taxonomy of the group. A section on their formation and geochemistry explains the kinds of environments where zeolites are formed. Then, an entry for each mineral series provides 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 about particular topics.

Book Description
Texas is known worldwide as a rich resource for the intricate Cretaceous-age echinoids widely sought by professional and amateur paleontologists. With much of the scientific literature on Texas Cretaceous echinoids decades old, here is an updated and detailed guide for identifying this rich fossil fauna. After a brief description of the climatic events that led to the formation of these marine deposits, readers are introduced to the terminology needed to understand the morphology and biology of echinoids. More than 350 high-quality color photographs and detailed descriptions provide a visual guide to identifying, usually to the species level, most of the Cretaceous echinoids found in Texas. The information will be of interest to nature lovers, new and advanced collectors, and students of invertebrate paleontology looking for in-depth, updated insights into the morphology, classification, and identification of these striking fossils.

Book Description
The Ozarks highland region of the Midwest, located in southern Missouri and northern Arkansas, contains beautiful mineral specimens for those with sharp eyes and a keen interest to discover minerals. Over 500 images represent the collectible minerals of the western Ozarks tristate district and Missouri's Viburnum Trend. Barite and fluorite as well as a variety of colorful copper, cobalt, nickel, and iron minerals grace the pages of this book, as do various forms of calcite and quartz, the latter of which can be a rock hound's delight. The fascinating and approachable text discusses these "Mississippi Valley Type" (MVT) minerals, their deposition, how they fit into the broader scope of North American mineralogy, and the locations of MVT minerals around the world. A focus of the book are those minerals that historically occur along the Ozarks' extensive waterways. This unique book is a must for anyone fascinated with the earth's natural beauty.
