Available in PDF, EPUB and Kindle. Book excerpt: Our colleagues from the French-speaking parts of Switzerland - the Suisses romands - and above all the committee of the 3rd Cycle, e Earth Sciences (3 Cycle, Sciences de la Terre) honored us by asking us to give a course on Isotope Geology for the year 1977. The course, entitled Evaluation et Interpretation des Donnees Isotopiques (eval uation and Interpretation of Isotopic Data), was intended to inform earth scientists, graduate and postgraduate, from the western Swiss Universities on the subject of Isotope Geology. Such courses usually consist of two parts: lectures and excursions. Thus, in March 1977, we gave such a two-week course at the Miner alogical Institute of the University of Berne. The first week was devoted essentially to the methods of dating, the second week to the behavior of stable isotopes. In July 1977, on the occasion of an excursion to the Central and Western Alps, we were able to demonstrate our results. Guest professors were invited to make contributions to the course.

Book excerpt: Geochemical Studies is a collection of papers dealing with ore petrology, particularly on the genesis of ores found in sediments. One paper describes the minor elements in metal deposits in sedimentary rocks, focusing on geochemical work on certain classes of ores in sediments and on the theories of origin of the deposits. With better techniques of microprobe analysis of trace elements, the paper notes that ore deposits in sedimentary rocks can be characterized by their minor element suites. One paper points out that large ore deposits cannot possibly be formed by a migration of substances (known as "negative" diffusion). The paper estimates that the quantities of material that can be accumulated in a sediment horizon with a great affinity for these materials, say in a period of one billion years, will still not be sufficient to produce a large ore deposit. The paper estimates the necessary diffusion coefficients that occur in deep structures, where increased mobilities of various substances occur. Geologists, geochemists, and engineers working with fossil fuels will find the collection highly significant.
Download or read book The Geology of Ore Deposits written by John M. Guilbert and published by Waveland Press. This book was released on 2007-02-09 with total page 1000 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern civilizations dependence upon an increasing volume and diversity of minerals makes the search for new ore deposits ever more difficult. Now available from Waveland Press, Guilbert & Parks text presents ideas, principles, and data fundamental for beginning economic geologists to understand the genesis and localization of ore deposits and of the minerals associated with them. The authors comprehensively describe the physical and chemical characteristics of ore deposits and correlate them with environments and conditions of deposition, since ore deposits are best interpreted as extensions of the environments responsible for their enclosing rocks. Examples and illustrations emphasize structural, chemical, and temporal controls and encourage the three-dimensional thinking used by productive explorationists as they face unsolved problems. This upper-level undergraduate text is fully illustrated and meticulously indexed. Its reliable, authoritative coverage assumes an upper-level command of chemistry and physics, as well as mineralogy, petrology, and structural geology. Outstanding features . . . develops and combines the abilities of the explorationist and of the researcher of ore-forming processes structures the geologic descriptions into groupings recognized by researchers and explorers alike builds confidence, revitalizes curiosity, and encourages expanded thinking emphasizes that the days of easy discovery of outcropping ores are not over includes revised, expanded, and updated descriptions of districts
Download or read book Stable Isotope Geochemistry written by Jochen Hoefs and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of this book was published in 1973, the second, totally rewritten, followed 7 years later in 1980. Because the field of stable isotopes is still grow ing and exerting an increasing influence on geosciences in general, it seems to be necessary, after a further 7 years, to revise the edition again accordingly. Not only has the previous edition been updated, but two completely new chapters on the isotopic composi tion of mantle-derived material and on the isotopic composition of the ocean during the geologie past, have been added. The references concentrate on re cent literature. In some cases, older references have been omitted to save space. I do not intend to underrate the value of older publications, but only to keep the reference list - al ready very voluminous in relation to the totallengt- from becoming even larger. An early draft has been reviewed by Russell Harmon and Alan Matthews. John Valley has se nt me a preprint of an artic1e on metamorphie rocks. To all three of them I owe my deepest thanks.

When discussing crystal structures and structural relationships, the sulfosalt minerals as well as the sulfides are considered in some detail.
Download or read book A The Terrestrial Environment written by P. Fritz and published by Elsevier. This book was released on 2016-07-29 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of Environmental Isotope Geochemistry, Volume 1: The Terrestrial Environment, A focuses on isotope hydrology and aqueous geochemistry, as well as an overview of carbon, sulfur, and nitrogen isotopes in terrestrial systems. The selection first elaborates on the isotopes of hydrogen and oxygen in precipitation, carbon-14 in hydrogeological studies, and environmental isotopes in groundwater hydrology. Concerns cover groundwater dating, mechanism of salinization, groundwater recharge, models of the isotope fractionation during evaporation and condensation of water in the atmosphere, and stable isotope distribution in atmospheric waters. The book then examines environmental isotopes in ice and snow, isotopic evidence on environments of geothermal systems, and sulfur and oxygen isotopes in aqueous sulfur compounds. Discussions focus on geochemistry and isotope distribution of aqueous sulfur compounds, isotopic dating of geothermal waters, origin of chemical constituents, geothermometry, isotope distribution during the reduction of a temperate snow cover, and snow and ice isotope hydrology. The manuscript explores environmental isotopes as environmental and climatological indicators, sulfur isotopes in the environment, nitrogen-15 in the natural environment, and the isotopic composition of reduced organic carbon. The selection is a valuable reference for researchers interested in isotope geochemistry.

Download or read book Geochemistry of Sedimentary Ore Deposits written by J.B. Maynard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an outgrowth of my interest in the chemistry of sedimentary rocks. In teaching geochemistry, I realized that the best examples for many chemical processes are drawn from the study of ore deposits. Consequently, we initiated a course at The University of Cincinnati entitled "Sedimentary Ore Deposits," which serves as the final quarter course for both our sedimentary petrology and our ore deposits sequence, and this book is based on that teaching experience. Because of my orientation, the treatment given is perhaps more sedimentological than is usually found in books on ore deposits, but I hope that this proves to be an advantage. It will also be obvious that I have drawn heavily on the ideas and techniques of Robert Garrels. A number of people have helped with the creation of this book. I am especially grateful to my students and colleagues at Cincinnati and The Memorial University of Newfoundland for suffering through preliminary versions in my courses. I particularly thank Bill Jenks, Malcolm Annis, and Dave Strong. For help with field work I thank A. Hallam, R. Hiscott, J. Hudson, R. Kepferle, P. O'Kita, A. Robertson, C. Stone, and R. Stevens. I am also deeply indebted to Bob Stevens for many hours of insightful discussion.
Download or read book Stable Isotope Geochemistry written by J. Hoefs and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 10 years have passed since RANKAMA'S second book, Progress in Isotope Geology, surveyed the literature on isotope abundance deter minations. In the meantime the number of measurements and publi cations has increased enormously. Therefore, it seems necessary to summarize the knowledge in this field in the light of more recent developments. The title of this book was chosen because the whole field of radio active isotope geochemistry has been deliberately omitted. The book is divided into three parts. Section A gives the theory of isotope effects and the technical background, both aspects being discussed rather briefly. The author regrets some shortcomings in the introductory section, especially in the theoretical treatment of isotope fractionation, but he has been trained mainly in earth sciences rather than in physical chemistry. Section B gives a summary of the fractionation mechanisms affecting the most important elements - hydrogen, carbon, oxygen, and sulfur. Further, it surveys some other elements that have not yet been as thoroughly investigated. Section C surveys the most important results from a geological stand point. In some cases the opinions of different authors on the same sub ject are summarized without comment, because the field of stable isotope geology is growing so rapidly that a final answer cannot be given at the moment. It is obvious that in writing this book, which is of the survey type, the author could not rely only on his own experiments and experience.

Download or read book Treatise on Geochemistry written by and published by Newnes. This book was released on 2013-10-19 with total page 14787 pages. Available in PDF, EPUB and Kindle. Book excerpt: This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry. In addition, the original Volume 1 on "Meteorites, Comets, and Planets" was expanded into two separate volumes dealing with meteorites and planets, respectively. These additions increased the number of volumes in the Treatise from 9 to 15 with the index/appendices volume remaining as the last volume (Volume 16). Each of the original volumes was scrutinized by the appropriate volume editors, with respect to necessary revisions as well as additions and deletions. As a result, 27% were republished without major changes, 66% were revised and 126 new chapters were added. In a many-faceted field such as Geochemistry, explaining and understanding how one sub-field relates to another is key. Instructors will find the complete overviews with extensive cross-referencing useful additions to their course packs and students will benefit from the contextual organization of the subject matter Six new volumes added and 66% updated from 1st edition. The Editors of this work have taken every measure to include the many suggestions received from readers and ensure comprehensiveness of coverage and added value in this 2nd edition The esteemed Board of Volume Editors and Editors-in-Chief worked cohesively to ensure a uniform and consistent approach to the content, which is an amazing accomplishment for a 15-volume work (16 volumes including index volume)!
Download or read book Isotopes in Economic Geology Metallogenesis and Exploration written by David Huston and published by Springer Nature. This book was released on 2023-06-19 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book documents the use of radiogenic and stable isotopes to study mineral deposits from a global to the deposit scale. It includes data-sets that have been directly used in mineral exploration. Isotopic data have been key to developing models for the origin of many mineral deposit types. The book has four sections: (1) the use of radiogenic isotopes to date mineral deposits, (2) the use of radiogenic isotope mapping to understand metal sources and regional- to district-scale controls on metallogenesis, (3) the use of light stable isotopes to determine fluid and sulfur sources, and (4) the use of metallic stable isotopes to understand the sources of ore metals. Each section includes chapters on specific isotopic systems and/or mineral systems that provide information on theory, analytical methods, uses in deposit and metallogenic studies, examples, and traps for young players.

Download or read book Polymetallic Metallogenic System written by Liqiang Yang and published by MDPI. This book was released on 2019-09-18 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last decade, the high and continuing demand for precious and base metals, as well as critical elements, has prompted a global rush on a scale never before seen. This eventually resulted in the demand for considerable innovation and improvement in mineral deposit genetic modelling and ore formation regimes for the many different types of gold deposits, now recognized, and paralleled by the wide employment of exploration techniques and a rapid expansion of geological databases. This Special Issue will show case studies of porphyry polymetal systems, orogenic gold formations, water–rock reaction, ore-forming structure evolution, mineralogy and petrology of ore deposit, ore formation regime, geochronology and geochemistry of ore deposit, ore-forming evolution, mineral exploration and cutting-edge technology in ore deposit study.
