Download or read book Giant Metallic Deposits written by Peter Laznicka and published by Springer Science & Business Media. This book was released on 2010-09-02 with total page 960 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metals in the earth's crust are very unevenly distributed and, traditionally, a small number of ore deposits, districts or countries have dominated the world supply and have influenced commodity prices. The importance of exceptionally large, or rich, deposits has greatly increased in the age of globalization when a small number of international corporations dominate the metals market, based on few very large ore deposits, practically anywhere in the world. Search for giant orebodies thus drives the exploration industry: not only the in-house teams of large internationals, but also hundreds of junior companies hoping to sell their significant discoveries to the "big boys". Geological characteristics of giant metallic deposits and their setting and the politico-economic constraints of access to and exploitation in prospective areas have been a "hot topic" in the past fifteen years, but the knowledge generated and published has been one-sided, scattered and fragmented. This is the first comprehensive book on the subject that provides body of solid facts rather than rapidly changing theories, written by author of the Empirical Metallogeny book series and founder of the Data Metallogenica visual knowledge system on mineral deposits of the world, who has had an almost 40 years long international academic and industrial experience. The book will provide abundant material for comparative research in metallogeny, practical information for the explorationists as to where to look for the "elephants", and some inspiration for commodity investors.

Download or read book Caldera Volcanism written by Joachim Gottsmann and published by Elsevier. This book was released on 2011-09-22 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume aims at providing answers to some puzzling questions concerning the formation and the behavior of collapse calderas by exploring our current understanding of these complex geological processes. Addressed are problems such as:- How do collapse calderas form? - What are the conditions to create fractures and slip along them to initiate caldera collapse and when are these conditions fulfilled? - How do these conditions relate to explosive volcanism?- Most products of large caldera-forming eruptions show evidence for pre-eruptive reheating. Is this a pre-requisite to produce large volume eruptions and large calderas?- What are the time-scales behind caldera processes? - How long does it take magma to reach conditions ripe enough to generate a caldera-forming eruption?- What is the mechanical behavior of magma chamber walls during caldera collapse? Elastic, viscoelastic, or rigid? - Do calderas form by underpressure following a certain level of magma withdrawal from a reservoir, or by magma chamber loading due to deep doming (underplating), or both?- How to interpret unrest signals in active caldera systems?- How can we use information from caldera monitoring to forecast volcanic phenomena?In the form of 14 contributions from various disciplines this book samples the state-of-the-art of caldera studies and identifies still unresolved key issues that need dedicated cross-boundary and multidisciplinary efforts in the years to come. - International contributions from leading experts - Updates and informs on all the latest developments - Highlights hot topic areas and identifies and analyzes unresolved key issues
Download or read book Ore Deposit Geology written by John Ridley and published by Cambridge University Press. This book was released on 2013-07-04 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mapping closely to how ore deposit geology is now taught, this textbook systematically describes and illustrates the major ore deposit types, linking this to their settings in the crust and the geological factors behind their formation. Written for advanced undergraduate and graduate students with a basic background in the geosciences, it provides a balance of practical information and coverage of the relevant geological sciences, including petrological, geochemical, hydrological and tectonic processes. Important theory is summarized without unnecessary detail and integrated with students' learning in other topics, including magmatic processes and sedimentary geology, enabling students to make links across the geosciences. Students are supported by further reading, a comprehensive glossary, and problems and review questions that test the application of theoretical approaches and encourage students to use what they have learnt. A website includes visual resources and combines with the book to provide students and instructors with a complete learning package.

Download or read book Preliminary Results of the Flin Flon Targeted Geoscience Initiative Saskatchewan and Manitoba written by Alan G. Galley and published by Natural Resources Canada. This book was released on 2002 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Flin Flon Paleoproterozoic volcanic belt of north central Manitoba & Saskatchewan contains numerous volcanogenic massive sulphide (VMS) deposits of great economic importance. In view of concerns about the long-term economic stability of that region, the Flin Flon Targeted Geoscience Initiative was established to gain a better understanding of the volcanic setting & hydrothermal signatures of these VMS deposits and to assist in the development of exploration strategies. This paper briefly reviews the geological setting of the project area and describes regional sub-projects of the Initiative. Topics of these sub-projects include oxygen isotope mapping, trace element signatures, detailed geologic mapping, volcanic rock alteration, and mine stratigraphy & geologic structure.

Download or read book Ore Deposits in an Evolving Earth written by G.R.T. Jenkin and published by Geological Society of London. This book was released on 2015-01-02 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ore deposits form by a variety of natural processes that concentrate elements into a volume that can be economically mined. Their type, character and abundance reflect the environment in which they formed and thus they preserve key evidence for the evolution of magmatic and tectonic processes, the state of the atmosphere and hydrosphere, and the evolution of life over geological time. This volume presents 13 papers on topical subjects in ore deposit research viewed in the context of Earth evolution. These diverse, yet interlinked, papers cover topics including: controls on the temporal and spatial distribution of ore deposits; the sources of fluid, gold and other components of orogenic gold deposits; the degree of oxygenation in the Neoproterozoic ocean; bacterial immobilization of gold in the semi-arid near-surface environment; and mineral resources for the future, including issues of resource estimation, sustainability of supply and the criticality of certain elements to society.

Available in PDF, EPUB and Kindle. Book excerpt: Metallic resources play a huge role in many fields: in the energy transition, the development of new technologies and the production and storage of green energy. Metallic Resources 2 presents various studies in notable metallogenic regions or deposits worldwide that enable us to tackle the question of the concentration of metals, especially strategic metals, in various geodynamic settings. An understanding of the geological processes that lead to the formation of deposits and influence their concentrations in the Earth's crust is of the utmost importance when it comes to uncovering new mineral resources. This book puts forward various different methodological approaches necessary in the study of deposits of metallic resources, from field observations to microanalysis. A study of specific geo-politico-economic frameworks is also presented.

Download or read book The Geology of Iberia A Geodynamic Approach written by Cecilio Quesada and published by Springer Nature. This book was released on 2019-08-20 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taking a new global approach, this unique book provides an updated review of the geology of Iberia and its continental margins from a geodynamic perspective. Owing to its location close to successive plate margins, Iberia has played a pivotal role in the geodynamic evolution of the Gondwanan, Rheic, Pangea, Tethys s.l. and Eurasian plates over the last 600 Ma of Earth's history. The geological record starts with the amalgamation of Gondwana in the Neoproterozoic succeeded by the rifting and spreading of the Rheic ocean; its demise, which led to the amalgamation of Pangea in the late Paleozoic; the rifting and spreading of several arms of the Neotethys ocean in the Mesozoic Era and their ongoing closure, which was responsible for the Alpine orogeny. The significant advances in the last 20 years have attracted international research interest in the geology of the Iberian Peninsula. This volume presents the most comprehensive, careful and updated description of the variscan cycle in Iberia. This volume focuses in the different geological events since the Cambrian-Early Ordovician rift until the late variscan orocline formations including magmatic and metamorphic evolution.
