Download or read book Formation of Gold Deposits written by Neil Phillips and published by Springer Nature. This book was released on 2022-06-16 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the origin of gold deposits to answer questions of science and curiosity. These answers contribute in turn to the improved exploration and mining of gold. Initially there is a summary of the methods used to address the genesis of gold deposits including some of the essential science and concepts. Five basic observations follow that apply to many gold deposits and need to be considered in any genetic ideas. Magmatic processes enriching gold are discussed followed by the role of aqueous fluids during gold deposit formation at elevated temperatures and pressures. Modifying effects after deposit formation include high-grade metamorphism, retrogression, weathering, and erosion. The main types of gold deposits are then explained within the spectrum of viable genetic ideas, with informal names for these examples that include gold-only, gold-plus, Carlin, slate-belt, epithermal, porphyry, iron oxide copper gold, and Archean greenstone. Case histories are included in which the role of gold geology contributed directly to discoveries—one example is at the province-scale and another at the goldfield-scale. Unlike other books on the subject, this one addresses virtually all gold deposit types rather than focusing on one type in isolation. The primary readership includes industry geologists, senior undergraduates, postgraduates, and those with some knowledge of science and an interest in the gold industry.

Download or read book Gold written by Boyle and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: GOLD: History and Genesis of Deposits is the product of an effort by the Society of Economic Geologists to publish materials that will expand knowl edge concerning timely, specific topics important to the study of economic geology and to economic geologists. A volume on gold was selected for a general review-type publication because of the importance of the gold mining industry in the 1980s. The officers and council of the Society of Economic Geologists authorized the preparation of this book on gold in 1981, and Dr. Robert W. Boyle was selected as its author. Dr. Boyle has extensive experience in the study of gold deposits. He has an international reputation and a broad interest and understanding of the gold mining industry, the origin of gold deposits, and the history of gold as a metal and ore from prehistoric times to recent. Dr. Boyle uses important publications on gold deposits as source materials to document the various pathways of geological thought over time to introduce the reader to modern concepts. The book contains a wealth of information concerning gold.

This book was released on 2021-03-10 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Minerals respond texturally and compositionally to changing magmatic environments and preserve a wealth of information regarding magmatic processes and compositions in their crystal-growth stratigraphy. This book reports the detailed petrography and in-situ geochemistry of the clinopyroxene phenocrysts of the mafic dykes in the Jiaodong Peninsula, southeastern North China Craton, including in-situ determinations of major elements, trace elements, Sr isotopic compositions, and H2O contents with further constraints on the petrogenesis and geodynamics of the mafic dykes. Systematic analyses of mineralogical, major, and trace elements, Sr–Nd isotopes, and in-situ S isotopes on the pyrite of the main gold-bearing mineral assemblages and visible gold were conducted, aiming to explore the source of ore-forming materials and the process of Au element migration and deposition. The geodynamic setting of mineralization in the studied region is also summarized.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes the nature and origin of the Macraes gold deposit. It also documents the key features of this spectacular deposit for a wide range of professionals in the resource geology community. This world-class gold deposit has been a spectacular geological and economic success story, as it has developed from a small historical gold mine in discontinuous quartz veins measuring only meters to a large-scale mine in deposits spreading over kilometres in extensive disseminated gold-bearing rock.

Available in PDF, EPUB and Kindle. Book excerpt: Details how Newmont Mining revolutionized the gold mining industry and remains the second largest gold miner in the world Jack H. Morris asserts that Newmont is the link between early gold mining and today’s technology-driven industry. We learn how the company’s founder and several early leaders grew up in gold camps and how, in 1917, the company helped finance South Africa’s largest gold company and later owned famous gold mines in California and Colorado. In the 1960s the company developed the process to capture “invisible gold” from small distributions of the metal in large quantities of rock, thereby opening up the rich gold field at Carlin, Nevada. Modern gold mining has all the excitement and historic significance of the metal’s colorful past. Instead of panning for ready nuggets, today’s corporate miners must face heavy odds by extracting value from ores containing as little as one-hundredth of an ounce per ton. In often-remote locations, where the capital cost of a new mine can top $2 billion, 250-ton trucks crawl from half mile deep pits and ascend, beetle-like, loaded with ore for extraction of the minute quantities of gold locked inside. Morris had unique access to company records and the cooperation of more than 80 executives and employees of the firm, but the company exercised no control over content. The author tells a story of discovery and scientific breakthrough; strong-willed, flamboyant leaders like founder Boyce Thompson; corporate raiders such as T. Boone Pickens and Jimmy Goldsmith; shakedowns by the Indonesian government and monumental battles with the French over the richest mine in Peru; and learning to operate in the present environmental regulatory climate. This is a fascinating story of the metal that has ignited passions for centuries and now sells for over $1,000 an ounce.

Download or read book Gold Deposits Of The CIS written by Gregory Levitan and published by Xlibris Corporation. This book was released on 2008-09-29 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Perestroika” in the former Soviet Union at the end of 1980s and subsequent breakdown of the country with the Common Wealth of Independent States (CIS) formation has opened a vast new region for the western mining companies for exploration and development. The possibility of finding unexplored gold deposits was one of the major incentives that attracted many small and big mining companies to CIS because this region of Eurasia is famous for containing the world’s largest cumulative gold reserve. However, because of the Soviet secrecy laws regarding all gold-related information, very little has been known about already explored gold deposits and their potential. “Gold Deposits of the CIS” represents the first comprehensive study in English of the gold and gold-silver deposits and their resources of the former Soviet Union. The book includes: (1) a history of gold exploration and mining in this region from ancient times, (2) the contemporary classification of the deposits, (3) a detailed description of more than 50 major and most representative gold and gold-silver deposits – all including their location, geological setting, structure, alteration style, mineralogy and resources and reserves and (4) the reserve estimation of all former Soviet gold-producing countries and their potential for possible new discoveries. Several explored and developed into production deposits, such as Kupol, Sarylakh, Sentachan, Natal'evskoye, Kuro-Tegerek, Zod, and some others, are described in English for the first time. The book gives a significant body of new information for exploration and mining companies, scientists, faculties and students of mining schools, as well as policy makers concerned with exploration and development of gold deposits in the world. Also, it provides important material for comparative studies between the gold deposits of the former Soviet Union and the West.
