Download or read book Mineralogy and Geochemistry of Ruby written by Frederick Lin Sutherland and published by MDPI. This book was released on 2020-12-07 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ruby, red corundum, is a gem mineral with mineral properties, gem characteristics and chemistry that are reliant on critical trace element substitutions in its aluminum oxide crystal structure. Ruby has attracted scientific and economic interest. It has already been studied extensively regarding its widespread global distribution and the diversity of its geological associations, as revealed by exploration and exploitation. Researchers are becoming increasingly aware that geographic typing of ruby characteristics and its host assemblages may guide further exploration and provide checks on reputed sources of both rough and cut stones. Genetic pointers, based on fluid and solid mineral inclusions, oxygen and other isotope values and pressure and temperature estimates, have already yielded much genetic information. Rare ruby in mantle xenoliths, TP ~1100o C, 2GPa, epitaxial diamond in ruby and ruby in diamond have special interest. Amid the present extensive documentation on this singular gem mineral, new insights and co-existing associations remain to be discovered. Although ruby largely appears in metamorphic and metasomatic source rocks, newer studies suggest it may also arise from magmatic sources. Age-dating of a range of mineral inclusions in ruby now allows more precise modelling of ruby genesis. Tectonic aspects of ruby genesis related to early collisional plate events on Earth are also a frontier for further understanding. In addition, ruby growth remains an important phase in metamorphic studies of events in some young collisional zones. This Special Issue planned for Minerals aims to attract further studies on this multi-origin gem mineral. Investigations at the ‘economic border’ of ruby and sapphire nomenclature and relevant treatments affecting ruby color will be considered.

Book excerpt: The advent of the twenty-first century was marked by a succession of conflicts and catastrophes that demanded unrestrained journalism. Hoskins and O'Loughlin demonstrate that television, tarnished by its economy of liveness and its impositions of immediacy, and brevity, fails to deliver critical and consistent expositions of our conflicting times.

Download or read book Gemmology written by P. G. Read and published by Elsevier. This book was released on 2013-10-22 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gemmology is a text for students preparing for the Gemmological Association's Preliminary and Diploma examinations. The book is more expansive and up-to-date than the author's earlier book, Beginner's Guide to Gemmology. The book deals with the practical and theoretical sides of gemmology. Tracing the background and science of gemmology, the book covers the gem material, geological formation, and occurrence of gemstones on the earth. The composition of gemstones from the atoms, elements, molecules, and compounds comprising them is analyzed, and the relationship between chemical composition and durability of the stone is explained. The basics of crystallography is mentioned as a tool toward understanding gemmology after which cleavage, parting, and fracture are done. A gemstone's durability and hardness and how the latter influences engineering tests and the mining techniques are compared. An important test technique to identify unmounted stones is the measure of specific gravity using displacement measurement methods and hydrostatic methods. After more descriptive details are given in identification of gemstones, whether these are synthetic or simulants, through a comprehensive explanation of the materials found in these other gemstones, the fashioning, through shaping or polishing, of gemstones is explained. Emphasis is given on the critical angle in which light rays pass in different rock densities, and then the cutting styles, gemstone polishing, and grading are discussed. Students studying for the Gemmological Association's Preliminary and Diploma examinations, jewelers, lapidarists, and diamond cutters, as well as those engaged in the hobby of gemmology, will find this book helpful and full of information toward their endeavors and hobbies.

Book excerpt: Fundamentally this article is a survey of applications of lasers. The applications are divided into six major areas: precision measurements, communications, biological and medical, other scientific areas, metalworking, and miscellaneous. A table of the basic characteristics of the major types of lasers is provided so that the user can be made aware of the limitations and capabilities of lasers. Good examples of applications in each of these areas are described in some detail to illustrate which major properties of laser radiation are useful in that particular area. Most of the discussion pertains to present-day applications but in some instances what appear to be good future applications are also described. Seventy-two references to the technical literature that relate to applications are provided.

Available in PDF, EPUB and Kindle. Book excerpt: Women who were sixty or older at the turn of the twenty-first century have lived through some of recent history's most momentous moments—and yet these women often believe that their personal lives and stories are insignificant, not worthy of being recorded for future generations. To change that perception and capture some of these life stories before they are lost, the Story Circle Network, a national organization dedicated to helping women write about their lives, developed the Older Women's Legacy (OWL) Circle Memoir Workshops. During the first two years of the project (1998-2000), nearly 500 older women participated in workshops that offered them the opportunity and encouragement to reflect on and create written records of their lives. With Courage and Common Sense presents an extensive selection of memoirs from the OWL Circle project. Organized thematically, they describe women's experiences of identity, place, work, family life, love and marriage, loss and healing, adventures great and small, major historical events, and legacies to keep and pass along. Taken as a whole, the memoirs chronicle far-reaching changes in the ways that women participated in the world during the twentieth century. They show how women learned to surmount obstacles, to courageously make the most of the opportunities that came their way, and to move quietly and wisely beyond the limits that were imposed upon them.
