Download or read book The Tourmaline Group written by Richard Vincent Dietrich and published by Springer. This book was released on 1985-11-30 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Collector s Guide to the Tourmaline Group written by R. J. Lauf and published by Schiffer Publishing Limited. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding gemstones in a geological context Gemstones are colorful treasures of the Earth that have captivated humans for thousands of years. The physical and chemical characteristics of each type of gem provide insights into the geological processes that created them. Geology and Mineralogy of Gemstones is a textbook aimed at upper-level undergraduate and graduate students. It presents the basic mineralogical and geological knowledge needed to understand gemstones and examines the characteristics and geological origins of different types of gemstone. Volume highlights include: Concepts in mineralogy Structure and chemical composition of minerals Geological processes that lead to the formation and movement of gemstones Equipment and tools used to examine gemstones and their physical properties The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Download or read book Metallogenic Mechanism of the Galinge Polymetallic Iron Skarn Deposit Qiman Tagh Mountains Qinghai Province written by Miao Yu and published by Springer. This book was released on 2019-02-15 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis summarizes the metallogenetic mechanism of the Galinge skarn deposit based on integrated knowledge of tectonics, geochemistry, geochronology, petrology, mineralogy, thermodynamics and hydrothermal fluids. It also discusses the multistage growth characteristics of various skarn minerals in which the varying compositions reflect the evolution of the hydrothermal fluid. The multidisciplinary nature of this research sheds new light on reconstructing metallogenetic processes successfully. It outlines the main aspects of skarn zonation based on the dominant contents of the skarn minerals and the wall rock compositions. In addition, it focuses on volatile-rich minerals including tourmaline and hastingsite, highlighting the importance of the volatile component in the skarn deposit. Lastly, it describes the regional tectonic–magmatic evolutionary history to explain the metallogenic principles, which can be used to guide prospecting in the field.
