This book was released on 2022-12-06 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold occurs in many settings, but the dynamic nature of Earth’s crust means overlapping and overprinting deposit styles are common. Characterization of mineralization from an early stage becomes important, particularly where the mineralization is complex, in order to maximize exploration and project development success and mining productivity. Various techniques are used at different stages of a project to characterize gold deposits. This Special Publication offers a cross-section of some specific techniques used to investigate a variety of gold deposit types. The papers highlight both the breadth of the available techniques and their utility in deposit characterization, but also the many significant remaining questions and problems related to the exploration and research of gold deposits. Several papers include suggestions of avenues for fruitful further research, including a paper discussing a new approach to classifying orogenic gold deposits, and a paper describing archaeological applications of natural gold analyses.

Book Synopsis A Scientific Bibliography of the Far Northern Drakensberg by : Rodney Moffett
Download or read book A Scientific Bibliography of the Far Northern Drakensberg written by Rodney Moffett and published by UJ Press. This book was released on 2023-04-14 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Scientific Bibliography of the “Far Northern Drakensberg” is a continuation by the Afromontane Research Unit of the University of the Free State (ARU) to document published and other similar works on the mountains of the summer rainfall area of South Africa. It follows “A Scientific Bibliography of the Drakensberg, Maloti and Adjacent Lowlands” which was published in 2020 (Moffett 2020), and which covered the area between the North-Eastern Cape and the North-Eastern Free State. The current work extends this northward by including articles and publications dating back to 1875 (E.Cohen, on the Lydenburg goldfields) reaching as far as the Wolkberg and Woodbush near Tzaneen in Limpopo Province. Figure 1 shows the boundary of the area covered, and although referred to as the Far Northern Drakensberg in this work, it is identical to that described as the LMEE, Limpopo, Mpumalanga & Eswatini Escarpment by Clarke et al (2022). Although slightly separate from the “lower” escarpment, the mountainous Barberton and adjacent Eswatini area, as well as the Leolo Mountains in eastern Sekhukhuneland are also included. Details on how the boundary in figure 1 was determined are given in Clark et al (2022). Bibliographies on two further ranges in the summer rainfall area, viz. the Magaliesberg in Gauteng province and the Soutpansberg in Limpopo province are to be the subject of future compilations.

Book Synopsis Applied Geothermics by : Lev Eppelbaum
Download or read book Applied Geothermics written by Lev Eppelbaum and published by Springer Science & Business. This book was released on 2014-04-29 with total page 757 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes origin and characteristics of the Earth’s thermal field, thermal flow propagation and some thermal phenomena in the Earth. Description of thermal properties of rocks and methods of thermal field measurements in boreholes, underground, at near-surface conditions enables to understand the principles of temperature field acquisition and geothermal model development. Processing and interpretation of geothermal data are shown on numerous field examples from different regions of the world. The book warps, for instance, such fields as analysis of thermal regime of the Earth’s crust, evolution and thermodynamic conditions of the magma-ocean and early Earth atmosphere, thermal properties of permafrost, thermal waters, geysers and mud volcanoes, methods of Curie discontinuity construction, quantitative interpretation of thermal anomalies, examination of some nonlinear effects, and integration of geothermal data with other geophysical methods. This book is intended for students and researchers in the field of Earth Sciences and Environment studying thermal processes in the Earth and in the subsurface. It will be useful for specialists applying thermal field analysis in petroleum, water and ore geophysics, environmental and ecological studies, archaeological prospection and climate of the past.
Book Synopsis Basement Tectonics 9 by : M.J. Rickard
Download or read book Basement Tectonics 9 written by M.J. Rickard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ninth International Conference on Basement Tectonics was held at the Australian National University in Canberra 2-6 July 1990. The opening keynote address was given by Prof. R.W.R. Rutland, Director of the Bureau of Mineral Resources. Other keynote speakers were E.S.T. O'Driscoll, an Australian consultant, and Prof P. Bankwitz, Central Institute for Physics of the Earth, Potsdam, GDR. Technical sessions were arranged by session conveners on the following five topic- i) The structure of the Australian craton and cover basins; ii) Basement structure of continental regions; iii) Structural patterns and mineral deposits; iv) Techniques for analysing basement structures; v) Structural patterns in oceanic crust. The arrangement of papers for this Proceedings Volume has been simplified. Part 1 deals with Australia, Part 2 with other areas and Part 3 lists the titles of all the papers read at the conference. Abstracts of these papers are available in Geological Society of Australia Abstracts No 26 and may be purchased for $AI0 from the Geological Society of Australia Office, ANA House, 301 George Street, Sydney NSW 2000. Field trips to view aspects of the Lachlan Fold Belt and the Sydney Basin were assisted by H.J. Harrington, D. Branagan, D. Wyborn, B. Drummond and M.J. Rick~d. A longer field trip, aborted through low enrolments, was organized by H.J. Harrington with assistance from W. Preiss, N. Cook, R. Glenn, A. Grady, and P. James; this assistance is gratefully acknowledged.
Book Synopsis U.S. Geological Survey Bulletin by : Paul Kibler Sims
Download or read book U.S. Geological Survey Bulletin written by Paul Kibler Sims and published by . This book was released on 1983 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Early Proterozoic Michigamme Formation of northern Michigan was deposited in the southeastern part of the Animikie basin. The formation conformably overlies the Goodrich Quartzite and comprises three widespread members a lower member of thin-bedded shale, siltstone, and sandstone; the Bijiki Iron-formation Member; and an upper member of tur- biditic graywacke, siltstone, and mudstone and a few local members. The Goodrich Quartzite is interpreted as having been deposited in a tidally influenced shallow marine environ- ment. The lower member of the Michigamme is interpreted as having been deposited in a tidally influenced environment, the iron-formation member as having been deposited below wave base in somewhat deeper water, and the upper member as having been deposited in still deeper water with turbidity currents being a major depositional mechanism. Several lines of evidence including paleocurrents, paleo- geographic setting, and neodymium isotopes suggest that the graywacke of the southern part of the outcrop area was derived from the south (Early Proterozoic Wisconsin magmatic terranes, Archean miniplates, and older Early Proterozoic sedimentary units formed on the continental margin), and that the graywacke in the northern area was derived from an Archean terrane to the north. The tectonic model that best fits the available data is a northward-migrating foreland basin.

Book Synopsis Gold metallogeny and exploration by : R. P. Foster
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.
Book Synopsis Potassic Igneous Rocks and Associated Gold-Copper Mineralization by : Daniel Müller
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 342 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 Synopsis Facies Models in Exploration and Development of Hydrocarbon and Ore Deposits by : Arnold H. Bouma
Download or read book Facies Models in Exploration and Development of Hydrocarbon and Ore Deposits written by Arnold H. Bouma and published by VSP. This book was released on 1991-06 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploration of natural resources is becoming more and more expensive. This means that more scientific approaches are needed using the best techniques available. However, no single technique can cover any of the objectives. Regional approaches, necessary to outline a prospective area, lack the detail required for exploration; detailed methods and techniques lack proper overview. A combination of both types of approaches and several techniques within are required to do optimal exploration. This book provides a number of examples (models) of different approaches and styles from different parts of the world, giving the reader not only new information but also a view of how different countries emphasize their exploration.
