This book was released on 1995 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the exploration and discovery histories of 54 major base- and precious-metal deposits around the Pacific rim over the last 25 years (1970-95). The discoveries are considered to be representative and to include all those of world-class deposits. Each case history places the discovery in a historical context and summarizes the geological, geochemical and geophysical work undertaken prior to discovery, followed by that completed through to production. The time frames and organizational aspects of the exploration programmes are emphiasized along with any special "twists". Each case history is prefaced by the background geology, including tonnage and grade data, and concludes with a brief summary.

Download or read book Gold Metallogeny and Exploration written by B. Foster and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 659 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 of all major aspects of gold 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.

Download or read book Potassic Igneous Rocks and Associated Gold Copper Mineralization written by Daniel Müller and published by Springer. This book was released on 2015-08-31 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the geochemical and petrological characteristics of potassic igneous rock complexes, and investigates the different tectonic settings in which these rocks occur. The authors provide an overview and classification of these rocks and elucidate the geochemical differences between barren and mineralized potassic igneous complexes. High-K rocks host a number of epithermal gold and porphyry copper-gold deposits. In recent years, there has also been growing recognition of an association of such rocks with iron-oxide copper-gold (IOCG) deposits, intrusion-related gold deposits (IRGDs) and possibly even Carlin-type gold deposits. This book is not only relevant to academic petrologists working on alkaline rocks, but also to exploration geologists prospecting for epithermal gold and/or porphyry copper-gold deposits in modern and ancient terrains. This fourth, updated and expanded edition incorporates new data and references from Africa, Australia, Brazil, China, Greece, Iran, Mongolia, North America, Russia and Turkey, including new maps and sections and new color plates of high-grade gold-copper ore from major deposits hosted by potassic igneous rocks.

Book excerpt: Extended for exploration/economic geologists in universities and mineral resources companies, mineralogists, geochemists and structural/regional geologists, this book provides a comprehensive account of Philippine gold deposits and geology. Epithermal gold deposits present a major challenge to geologists as the nature of surface environment beneath which major deposits develop and the regional geological controls by the creation of major deposits remains poorly understood. New ideas on the genesis of gold deposits and relationship to Phillipine tectonics together with new data on South East Asia gold and tectonics are covered.

Download or read book Geochemical Anomaly and Mineral Prospectivity Mapping in GIS written by E.J.M. Carranza and published by Elsevier. This book was released on 2008-11-26 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geochemical Anomaly and Mineral Prospectivity Mapping in GIS documents and explains, in three parts, geochemical anomaly and mineral prospectivity mapping by using a geographic information system (GIS). Part I reviews and couples the concepts of (a) mapping geochemical anomalies and mineral prospectivity and (b) spatial data models, management and operations in a GIS. Part II demonstrates GIS-aided and GIS-based techniques for analysis of robust thresholds in mapping of geochemical anomalies. Part III explains GIS-aided and GIS-based techniques for spatial data analysis and geo-information sybthesis for conceptual and predictive modeling of mineral prospectivity. Because methods of geochemical anomaly mapping and mineral potential mapping are highly specialized yet diverse, the book explains only methods in which GIS plays an important role. The book avoids using language and functional organization of particular commercial GIS software, but explains, where necessary, GIS functionality and spatial data structures appropriate to problems in geochemical anomaly mapping and mineral potential mapping. Because GIS-based methods of spatial data analysis and spatial data integration are quantitative, which can be complicated to non-numerate readers, the book simplifies explanations of mathematical concepts and their applications so that the methods demonstrated would be useful to professional geoscientists, to mineral explorationists and to research students in fields that involve analysis and integration of maps or spatial datasets. The book provides adequate illustrations for more thorough explanation of the various concepts. Explains GIS functionality and spatial data structures appropriate regardless of the particular GIS software in use Simplifies explanation of mathematical concepts and application Illustrated for more thorough explanation of concepts

Available in PDF, EPUB and Kindle. Book excerpt: Experts in the field offer the first comprehensive review of the tectonics and magmatism of backarc basins, covering their initial rift stage to mature spreading. Complete with numerous illustrations, each of the twelve chapters focuses on a young, active backarc basin of the circum-Pacific-where volcano-tectonic processes are best studied because of their activity. Key themes in this volume include volcano-tectonics setting; cause and location; rift magmas; and hydrothermal activity. Researchers also present models of the dynamic processes occurring in backarc basins.
