Available in PDF, EPUB and Kindle. Book excerpt: Nickel Sulfide Ores and Impact Melts: Origin of the Sudbury Igneous Complex presents a current state of understanding on the geology and ore deposits of the Sudbury Igneous Complex in Ontario, Canada. As the first complete reference on the subject, this book explores the linkage between the processes of meteorite impact, melt sheet formation, differentiation, sulfide immiscibility and metal collection, and the localization of ores by magmatic and post-magmatic processes. The discovery of new ore deposits requires industry and government scientists and academic scholars to have access to the latest understanding of ore formation process models that link to the mineralization of their host rocks. The ore deposits at Sudbury are one of the world’s largest ore systems, representing a classic case study that brings together very diverse datasets and ways of thinking. This book is designed to emphasize concepts that can be applied across a broad range of ore deposit types beyond Sudbury and nickel deposit geology. It is an essential resource for exploration geologists, university researchers, and government scientists, and can be used in rock and mineral analysis, remote sensing, and geophysical applications. Provides the only reference book to focus entirely on the Sudbury Igneous Complex Brings together an understanding of ore deposit and impact melts as a basis for future exploration Authored by a leading expert on the geology of the Sudbury Igneous Complex with 35 years of experience working on nickel sulfide ore deposits

Available in PDF, EPUB and Kindle. Book excerpt: The Geo-Platinum 87 Symposium, held at the Open University during April 1987, was designed as a forum for presentation of new research results on the occurrence, genesis, geochemistry, mineralogy and analysis of the platinum-group elements (PGE). With the support of the Open University and the Mineral Industry Research Organisation, the symposium was attended by 115 representatives of university departments, research institutions and members of the mining and mineral exploration industries. An introduction to the symposium was provided by two invited papers from C. J. Morrissey (Riofinex North) and C. R. N. Clark (Johnson Matthey) which were designed to give perspective to the goals of PGE research work. The first of these papers gave a provocative insight into the aims and objectives of an exploration manager, examining the influence of supply, demand and perceived world reserves on exploration strategy. The second invited paper gave a valuable view of the industrial uses, market trends and predicted changes in the commercial value of the platinum-group elements from the standpoint of a refining company and supplier. These invited papers are reproduced in this volume and are followed by twenty four full papers and twenty abstracts that reflect the wide range of research topics presented at the symposium.
Download or read book Processes and Ore Deposits of Ultramafic Mafic Magmas through Space and Time written by Sisir K. Mondal and published by Elsevier. This book was released on 2017-09-08 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Processes and Ore Deposits of Ultramafic-Mafic Magmas through Space and Time focuses on the fundamental processes that control the formation of ore deposits from ultramafic-mafic magmas, covering chromite, platinum-group element (PGE), Ni-sulfides and Ti-V-bearing magnetite. The exploration, exploitation and use of these magmatic ores are important aspects of geology and directly linked to the global economy. Magmatic ores form from ultramafic-mafic magmas and crystallize at high-temperature after emplacement into crustal magma chambers, and are genetically linked to the evolution of the parental magmas through space and time. This book features recent developments in the field of magmatic ore deposits, and is an essential resource for both industry professionals and those in academia. Elucidates the relationships between tectonic settings and magmatic ore mineralization Provides the links between magma generation in the mantle and ore mineralization at crustal levels Features the latest research on changing patterns in magmatic ore mineralization through time and their bearing on the chemical evolution of the Earth’s mantle

Book excerpt: This monograph resulted from a Symposium held at Stanford University on November 12 and 13, 1966. This was conceived in 1962 when the Program Policy Committee recommended that the Society of Economic Geologists should sponsor a symposium on magmatic ore deposits, prompted by the realization that the underlying theory of the formation of magmatic ore deposits was formulated many decades ago. In the intervening years, much new data had been acquired from systematic research, and it was therefore time to assess this new data and to point out the unresolved problems.
Download or read book Understanding Mineral Deposits written by Kula Misra and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 857 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mineral deposits have supplied useful or valuable material for human consumption long before they became objects of scientific curiosity or commercial exploitation. In fact, the earliest human interest in rocks was probably because of the easily accessible, useful (e. g. , red pigment in the form of earthy hematite) or valuable (e. g. , native gold and gemstones) materials they contained at places. In modem times, the study of mineral deposits has evolved into an applied science employing detailed field observations, sophisticated laboratory techniques for additional information, and computer modeling to build complex hypotheses. Understanding concepts that would someday help geologists to find new mineral deposits or exploit the known ones more efficiently have always been, and will continue to be, at the core of any course on mineral deposits, but it is a fascinating subject in its own right, even for students who do not intend to be professional economic geologists. I believe that a course on mineral deposits should be designed as a "capstone course" that illustrates a comprehensive application of concepts from many other disciplines in geology (mineralogy, stratigraphy and sedimentation, structure and tectonics, petrology, geochemistry, paleontology, geomorphology, etc. ). This book is intended as a text for such an introductory course in economic geology, primarily for senior undergraduate and graduate students in colleges and universities. It should also serve as a useful information resource for professional economic geologists.
Download or read book Structural Control of Mineral Deposits written by Alain Chauvet and published by MDPI. This book was released on 2019-04-16 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Structural Control” remains a crucial point that frequently lacks in any scientific and/or economic analysis of ore deposits, whatever their type and class. The case of lode deposits is exemplary, although also other deposits, like breccia pipe, stockwerk, massive sulphides, skarn, etc., can, surprisingly, be concerned. Several concepts like the gold-bearing shear zone have not proven valid during the last few decades in terms of our understanding of gold deposit and have been totally abandoned. Additionally, the relationships between magmatism, regional tectonic context, and mineralization remain uncertain and have been debated in several recent publications. This demonstrates that this issue is still relevant, and its solution may help in the distinction between intrusion-related and orogenic deposits. In this Special Issue, we particularly invite any case study of mineral deposits, in which it has been demonstrated that structural geology may have a significant role in the establishment of the deposit model of formation and/or on exploration and exploitation programs. Examples in which the structural model diverges from those described in the classical literature are particularly welcomed, including studies in which relationships with magmatism can be suspected and/or demonstrated. Indeed, all cases that illustrate concepts that differ from the classic ones and from theoretical models may represent significant contributions to this volume.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the comprehensive volume of the TAIGA (“a great river ” in Japanese) project. Supported by the Japanese government, the project examined the hypothesis that the subseafloor fluid advection system (subseafloor TAIGA) can be categorized into four types, TAIGAs of sulfur, hydrogen, carbon (methane), and iron, according to the most dominant reducing substance, and the chemolithoautotrophic bacteria/archaea that are inextricably associated with respective types of TAIGAs which are strongly affected by their geological background such as surrounding host rocks and tectonic settings. Sub-seafloor ecosystems are sustained by hydrothermal circulation or TAIGA that carry chemical energy to the chemosynthetic microbes living in an extreme environment. The results of the project have been summarized comprehensively in 50 chapters, and this book provides an overall introduction and relevant topics on the mid-ocean ridge system of the Indian Ocean and on the arc-backarc systems of the Southern Mariana Trough and Okinawa Trough.
Download or read book Microstructural Characterisation of Sulphide and Oxide Minerals in Magmatic Sulphide Ores written by Zoja Vukmanovic and published by . This book was released on 2013 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] Magmatic sulphide ore deposits are a major source of economically valuable commodities such as Ni, Cu and platinum group elements (PGE). These deposits form as a result of the segregation and concentration of sulphide liquid droplets from mafic and ultramafic magmas. The geochemistry and petrology of these systems has been extensively studied, as have regional and outcrop scale aspects of the structural geology of deformed deposits. However, microstructural work on igneous rocks in general and magmatic ore systems in particular has received relatively little attention to date. Microstructural studies can help in understanding the large scale deformation process, through investigation of the development of micro-scale textures such as crystallographic preferred orientations and development of exsolution features. Investigation of intragrain microstructures can identify the presence of dislocation arrays within the crystals that accompany grain-scale deformation and potentially facilitate element diffusion, and allow fundamental understanding of the grain-scale process that control the bulk rheology of sulphide ores during deformation. Understanding the relative strengths and deformation mechanisms of the common mineral species is relevant to an ongoing controversy about the role of mechanical differentiation of polyphase sulphide assemblages in controlling short range variability in ore tenors. This thesis describes the first study to employ electron backscatter diffraction (EBSD) analysis to investigate textures and intragrain microstructures within magmatic sulphide and oxide minerals. The study focuses on two types of deposits, komatiitic hosted Ni sulphides (Yilgarn Craton, Western Australia) and layered intrusion-hosted PGE-rich disseminated sulphides (Bushveld Complex, South Africa). Electron backscatter diffraction data is also coupled with laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) and Nano-scale secondary ion mass spectrometry (NanoSIMS) data to understand how deformation controls mineral chemistry at the micro-scale. In addition, EBSD microstructural results have been coupled with X-ray micro-tomography data to gain a greater understanding of the 3D morphology of the sulphides and other phases. Through the study of differently deformed komatiite hosted Ni deposits from the Yilgarn craton, and tectonically undisturbed layered intrusions, the Bushveld Complex, this thesis addresses the following objectives: a) obtaining fundamental information on physical properties and deformation mechanisms of pyrrhotite, pentlandite and pyrite under different tectonic conditions, b) trace element behaviour during deformation of sulphides and c) behaviour of sulphides and associate phases in tectonically undisturbed magmatic environments...
