Download or read book Gemstones and Their Origins written by P.C. Keller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each gem deposit-whether of primary origin in the parent rocks; or secondary as alluvial placers in valley floors, river gravels, or the sand of oceanic shelves presents an eloquent chronicle of the Earth's life story. It reveals to the expert the prodigious processes which formed the present crust of our planet, of which this volume discloses a small but exciting detail. The materials of the Earth's crust are the rocks. In this book, the author expounds on how they were formed, why they altered, why they became the cradles of precious gemstones, how they are categorized, and how they are now exploited by man. What initiates the growth of gemstones? How do they crystallize? Why do gemstones of the same species, originating from different sources, vary? What causes the occurrence of varieties? Why do diamonds, unlike other precious stones, occur not near the Earth's surface in its crust, but deep down beneath it in the upper mantle? These are only a few of the entrancing subjects discussed in this enlightening volume. The reader learns that the Earth is surprisingly alive and altering constantly-sometimes through slow and equable changes and at times by violent and tremendous cataclysms, events from which gemstones issue.

Download or read book The International Tin Cartel written by John Hillman and published by Routledge. This book was released on 2010-02-25 with total page 915 pages. Available in PDF, EPUB and Kindle. Book excerpt: For most of the twentieth century, tin was the site of new forms of international regulation which became a model for other commodities. The onset of the depression of the 1930s saw a collapse in commodity prices, and governments of tin producing countries decided to form a cartel to return the industry to comparative prosperity. This is a detailed study of how the tin industry found itself in difficulty and how the cartel developed its policies of control over production and stocks, together with its enduring legacy after World War II. This study of a cartel brings together two levels of analysis that are normally kept separate; international cooperation, and national organization, and demonstrates how each affected the other. It is based on a comprehensive review of a wide range of archival sources which are sufficiently rich and frank that they provide an insider’s sense of how a cartel actually worked.

Download or read book Gemstones written by Michael O'Donoghue and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gemstones is the first attempt in English to bring together the geological, mineralogical and gemmological developments that have taken place during the last thirty years. Though there have been many gemstone books published in that time, most have been concerned, understandably and rightly, with the science of gem testing and have covered that area very well. Details of the geological occurrence of many of the classic gemstones, and of nearly all those which have only recently been discovered, have been less adequately dealt with. Coverage has been restricted to a number of papers in a wide variety of geological and mineralogical journals. Gemstones hopes to get the balance right. In the preparation of the book all the journals and monographs in the field have been consulted so that the book should stand for some years as the authority to which gemmologists and others turn in the first instance. Ease of reference and depth of coverage make Gemstones both a reference book and a bench book. Acknow ledgements I am grateful to Brian Jackson of the Department of Geology, Royal Museums of Scotland who read the manuscript and painstakingly indicated places where amendment or alteration was needed. I am also grateful to the publishers of the books on which the line illustrations are based. The colour plates present in the book derive from a number of sources, which I would like to acknowledge as follows. Plates 1, 4-15 and 17 Crown copyright reserved.
Download or read book The Chinese in America written by Susie Lan Cassel and published by Rowman Altamira. This book was released on 2002 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new collection of essays demonstrates how a politics of polarity have defined the 150-year experience of Chinese immigration in America. Chinese-Americans have been courted as 'model workers' by American business, but also continue to be perceived as perpetual foreigners. The contributors offer engrossing accounts of the lives of immigrants, their tenacity, their diverse lifeways, from the arrival of the first Chinese gold miners in 1849 into the present day. The 21st century begins as a uniquely 'Pacific Century' in the Americas, with an increasingly large presence of Asians in the United States, Canada, and Mexico. The book will be a valuable resource on the Asian immigrant experience for researchers and students in Chinese American studies, Asian American history, immigration studies, and American history.
