Download or read book The Metallogeny of Lode Gold Deposits written by Ulrich Kretschmar and published by Elsevier. This book was released on 2015-11-24 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Metallogeny of Lode Gold Deposits: A Syngenetic Perspective is a synthesis of lode gold vein forming processes, addressing the commonality in similar worldwide deposits. The book's empirical model incorporates widely known and accepted principles of ore deposition and shows how it applies in the volcanic-sedimentary greenstone belt environment. Several chapters detail outcrop maps and photos of field occurrences and textures. The interpretations flow directly from the authors' field work, and are coupled with analyses of underlying physical processes. Utilizing detailed geological mapping, field work, and chemical analyses as the basis of a syngenetic formation mode, the text arms readers with the tools necessary to accurately analyze and interpret new data on the subject. This includes information on decoding the significance of asymmetry in vein formation, as well as the role of lamprophyres in gold camps, how Archean geology requires integration into a lode vein formation model, and how to develop an understanding of the worldwide applicability of gold cycles to lode vein formation and exploration and how it can be applied to deposits of all ages. - Presents the first book to galvanize lode gold research into a single authoritative reference - Simplifies the complexity of lode gold's underlying processes and presents valid concepts surrounding the lode gold forming environment - Features color figures, illustrations, and photos that enrich the content's focus and aid in the retention of key concepts

Download or read book Gold metallogeny and exploration written by R. P. Foster and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last decade, the high and continuing demand for gold has prompted a global gold rush on a scale never before seen, not even in the heady days of Ballarat, California and the Yukon. Gold is being sought on every continent and, with very few exceptions, in every country around the world. Such interest and fierce competition has demanded considerable innovation and improvement in exploration techniques paralleled by a rapid expansion of the geological database and consequent genetic modelling for the many different types of gold deposits now recognized. This proliferation of data has swamped the literature and left explorationist and academic alike unable to sift more than a small proportion of the accumulating information. This new book represents an attempt to address this major problem by providing succinct syntheses ofall major aspects ofgold metallogeny and exploration, ranging from the chemical distribution of gold in the Earth's crust, and the hydrothermal chemistry of gold, to Archaean and Phanerozoic lode deposits, epithermal environments, chemical sediments, and placer deposits, and culminates in chapters devoted to geochemical and geophysical exploration, and the economics of gold deposits. Each chapter is written by geoscientists who are acknowledged internationally in their respective fields, thus guaranteeing a broad yet up-to-date coverage. In addition, each chapter is accompanied by reference lists which provide readers with access to the most pertinent and useful publications.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Placer Gold Deposits of Nevada Following the discovery of placers at Gold Canyon, placer discoveries in Nevada were broadly in three periods: the 1860's to 1880's, when many small deposits throughout the State were discovered and sporadically worked and several large placers were discovered and extensively worked; the short period between 1906 and 1910, when very rich placers were dis covered at Lynn, Battle Mountain, Manhattan, and Round Mountain; the early 1930's, when economic conditions created by the depression caused a renewed interest in placer mining, and many individuals sought, and a few discovered, new placer areas throughout the State. The location of the placers described in this report is shown on plate 1. Very little factual information can be found about the early periods of placer mining in Nevada. For many placers, the only reports available are hearsay estimates of production and speculations about the extent of the placer ground based on remnants of placer pits, shafts, and other workings. Many of the placers said to have had a high production between 1860 and 1890 were worked by Chinese miners who came to Nevada dur ing the building of the railroads and stayed on to work at mining and other activities. The Chinese were reputed to be secretive with their earnings from the placers and did not ship the gold to the mint by Wells Fargo or other shippers. They worked the gravels very thoroughly in areas where American miners did not wish to expend great labor to win the gold. The placers in the Sierra and Spring Valley districts, Pershing County, were worked by Chinese miners; they have a very high estimated production before 1900 and a comparatively low known production since that time.

Download or read book Prehistoric Gold in Europe written by Giulio Morteani and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in the study of early European cultures is growing. These cultures have left us objects made of gold, other metals and ceramics. The advent of metal detectors, coupled with improved analytical techniques, has increased the number of findings of such objects enormously. Gold was used for economic and ceremonial purposes and thus the gold objects are an important key to our understanding of the social and political structures, as well as the technological achievements, of Bronze and Iron Age European societies. A correct interpretation of the information provided by gold and other metal objects requires the cooperation of experts in the fields of social, materials and natural science. Detailed investigation of gold deposits in Europe have revealed the composition and genesis of the deposits as sources of the metal. In Prehistoric Gold in Europe, a group of leading European geoscientists, metallurgists and archaeologists discuss the techniques of gold mining and metallurgy, the socioeconomic importance of gold as coinage and a symbol of wealth and status, and as an indicator of religious habits, as well as a mirror of trade and cultural relations mirrored by the distribution and types of gold objects in prehistoric times.
Download or read book Gold and Gold Mining in Ancient Egypt and Nubia written by Rosemarie Klemm and published by Springer Science & Business Media. This book was released on 2012-12-13 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents the historical evolution of gold mining activities in the Egyptian and Nubian Desert (Sudan) from about 4000 BC until the Early Islamic Period (~800–1350 AD), subdivided into the main classical epochs including the Early Dynastic – Old and Middle Kingdoms – New Kingdom (including Kushitic) – Ptolemaic – Roman and Early Islamic. It is illustrated with many informative colour images, maps and drawings. An up to date comprehensive geological introduction gives a general overview on the gold production zones in the Eastern Desert of Egypt and northern (Nubian) Sudan, including the various formation processes of the gold bearing quartz veins mined in these ancient periods. The more than 250 gold production sites presented, are described both, from their archaeological (as far as surface inventory is concerned) and geological environmental conditions, resulting in an evolution scheme of prospection and mining methods within the main periods of mining activities. The book offers for the first time a complete catalogue of the many gold production sites in Egypt and Nubia under geological and archaeological aspects. It provides information about the importance of gold for the Pharaohs and the spectacular gold rush in Early Arab times.
