Download or read book Collector s Guide to the Garnet Group written by R. J. Lauf and published by Schiffer Publishing. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.
Download or read book Collector s Guide to the Epidote Group written by Robert J. Lauf and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 90 striking color photos display minerals of the epidote group, well known to mineral collectors for their rich colors and the many interesting minerals with which they occur. Lapidary artists also value epidote, particularly in the form of unakite, and precious or semiprecious varieties of the related mineral zoisite, including thulite and tanzanite, some which have inclusions that allow them to be cut into popular catseyes. This informative book provides all presently known species, detailed entries for each of the eighteen minerals, and extensive locality information. This book will be of interest to those interested in developing a better understanding of silicate minerals.

Download or read book Collector s Guide to the Zeolite Group written by Robert J. Lauf and published by Schiffer Publishing. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-09-27 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2012 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: "none", Abubakar Tafawa Balewa University (School of Science), course: Economic Geology-Mineral Exploration, language: English, abstract: The research work “Geology and Petrochemistry of Granitic Pegmatites in Jema’a Field” is a systematic study of the pegmatites in relation to the adjoining granitoids (biotite muscovite granite, albite granite and granite aplite) with a view to understanding their geological and geodynamic evolution and subsequent economic potential through the behavior of rare elements. The field work was conducted on a scale of 1:50, 000. 33 rocks and mineral separates extracted from pegmatites were analyzed. The samples were subdivided into two parts; one part was analyzed using X-Ray Fluorescence to generate data on major and minor elements, while Instrumental Neutron Activation Analysis was used to generate data on trace elements. The other part of the samples was made into thin section for petrographic studies. Petrochemical and petrographic interpretations concur on the changes in colour of micas from brown biotite in granitoids to blue muscovite, to purplish green mica to purple mica in the pegmatites corresponding to increase in rare elements (Rb, Cs, Na, Ta, Nb, Ga) and volatiles (P, H2O, F) from the granitoids into the pegmatites. This constitute a fractionation trend. This is also strongly supported by fairly consistent increase in Aluminum Saturation Index (A/CNK), normative corundum, normative albite, Lost on Ignition (LOI), differentiation Index (DI) and corresponding decrease in Ba, Zr and Ti. The pegmatites contains more fluxes and liquidus depressing elements (P, H2O, F) especially phosphorus. The granitoids (biotite muscovite granite, albite granite and granite aplite) are therefore fertile, peraluminous, siliceous and S-type and are parental to the pegmatites. The feldspars display perthitic textures which show incomplete solid solution and lowering of liquidus. The tectonic discrimination of the granitoids and the pegmatites show that they were formed within syncollisional, peraluminous, and active continental margin. The research suggest fractionation as a metallogenetic process. The genetic model presents the granitoids ; biotite muscovite granite, albite granite and granite aplite as products of internal chemical differentiation of a fractionating batholiths where NaO replaces K2O as the system is cooling. This is common to most granite-rare-elements-pegmatites systems all over the world. Fractionation via rare elements accumulations is therefore an exploration tool.
