Syngenesis and Epigenesis in the Formation of Mineral Deposits by A. Wauschkuhn,C. Kluth,R.A. Zimmermann Pdf
The papers in this volume are dedicated to Professor Dr. Dr. h.c. G. Christian Amstutz by his colleagues, friends, and students on the occasion of his 60th anniversary. The authors of this book - the theme was restricted to syngenesis and epigenesis in the formation of mineral deposits - wish to honour with their articles a scientist who has contributed to, and substantially promoted the understanding of the genesis of mineral deposits in the last decades. The majority of the articles deal with strata-bound depos its, thus reflecting one of his main scientific interests. In the tradition of his professors, Paul Niggli and Paul Ramdohr, G.C. Amstutz has maintained an open and active interest in many fields of earth science. His numerous papers have triggered a remarkable number of new ideas and investigations in a variety of fields, and the "happy marriage" of economic geology with sedimentology is cer tainly one of his main successes, starting with the first Symposium on Sedimentology and Ore Genesis at the Sixth International Sedimentological Congress at Delft in 1963.
An important prerequisite to the long-term use of nuclear energy is information on uranium ore deposits from which uranium can be economically exploited. Hence the basic purpose of this book is to present an overview of uranium geology, data characteristic for uranium deposits, and a synthesis of these data in the form of a typological classification of uranium deposits supported by more detailed descriptions of selected uranium districts and deposits. An additional goal is to provide access for the interested reader to the voluminous literature on uranium geology. Therefore a register of bibliography as global as possible, extending beyond the immediate need for this book, is provided. The volume presented here was not originally designed as a product for its own sake. It evolved as a by-product during decades of active uranium exploration and was compiled thanks to a request by the Springer Publishing Company. Routine research work on identifying characteristic features and recognition criteria of uranium deposits, combined with associated modeling of types of deposits for reapplication in exploration, provided the data bank. The publisher originally asked for a book on uranium deposits structured as a combined text- and reference book. The efforts to condense all the text into a single publication were soon doomed. The material grew out of all feasible proportions for a book of acceptable size and price, a wealth of data on uranium geology and related geosciences having become available during the past decade, too vast for one volume.
Mineral Deposits within the European Community by Jean Boissonnas,Paolo Omenetto Pdf
Results of selected projects on Exploration R & D, one of the major research areas implemented by the Commission of European Communities in Brussels on the subject of mineral raw materials, are presented on an international basis. All aspects of the geology and geochemistry of ore deposits and their host rocks are covered. Main headings are according to commodity, i.e. tungsten, chromite, and base metals, rather than by scientific criteria. The scope and subject matter varies from the metallogenic province to the individual deposit. The question of possible application to exploration methodology is explored in several papers. Particularly structural and geochemical techniques are discussed.
Annotated Bibliographies of Mineral Deposits in Europe by J.D. Ridge Pdf
This volume provides bibliographic and textural information which gives a real understanding of the 40 ore deposits in Western and West Central Europe. Each deposit is introduced by a selected bibliography listing the most important literature. This is followed by a detailed discussion covering geological characteristics including the position, grade and tonnage of the ore produced together with potential reserve, the stratigraphy and structure of the rocks of the district, and the characteristics and age of the ore body. The book also includes a section of maps, pin-pointing the most important mineral deposits in each region, making this work a valuable reference source for all those working in the fields of ore-deposit geology and exploration.
This is the first comprehensive book on the geological characteristics of giant metallic deposits that provides solid facts rather than rapidly changing theories. The book provides abundant material for comparative research in metallogeny, practical information for the explorationists as to where to look for the "elephants", and inspiration for commodity investors.
Ore Geology and Industrial Minerals by Anthony M. Evans Pdf
Much new data and many new ideas have emerged in the area of oregeology and industrial minerals since publication of the secondedition of this text in 1987. The overriding philosophy behind thisnew edition is the inclusion and integration of this new materialwithin the established framework of the text. The third edition isre-presented in the modern double-column format. Non-metallic deposits of industrial and bulk materials are fullycovered to meet the changing emphasis of courses in appliedgeology. In addition, chapter 1 has been considerably enlarged toinclude a section on mineral economics covering metals, industrialminerals and bulk materials. In this section, the various aspectsof economic exploitation of industrial and bulk materials arecompared with those of metallic deposits. Other major revisions andadditions include a section on fluid inclusions, expansion of thesection on wall rock alteration, expansion of the material onisotope studies, and the inclusion of a section on hydraulicfracturing and seismic pumping.
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.
Sediment-Hosted Zn-Pb Ores by Lluis Fontbote,Maria Boni Pdf
Sediment-hosted deposits are the main source of zinc and lead. In this volume, the reader will find the most recent developments in research including: - Fluid migration leading to formation of Zn-Pb ores in sedimentary basins. Relationships to orogenic events and to geothermic anomalies - Transport of metals and precipitation mechanisms. The role played by fluid mixing, fluid-rock reaction, organic matter, and thiosulfates - Paleomagnetic dating of ore deposits - The association of Mississippi Valley-type ore deposits to diapiric salt structures - Geochemical investigations applied to exploration for sediment-hosted Zn-Pb deposits - Economic aspects. The broad geographical coverage is an additional aspect which will interest both researchers and explorationists.
THE DYNAMIC EARTH SYSTEM, Fourth Edition by PATWARDHAN, A. M. Pdf
Addressed to the undergraduate and postgraduate students pursuing studies in the broad interdisciplinary field of Earth Science, this thoroughly revised book, in its Fourth Edition, is aimed at facilitating the comprehension between the pre-planetary history and the subsequent geological processes of the Earth system. This is done keeping in mind the current interest in exoplanets and the evolution of the life supporting crustal composition of the Earth, much different from that of the other planets, in terms of the Earth's internal heat, density distribution and the strong magnetic field due to the dominant presence of metallic Fe in its core. The new edition draws the attention of the reader to the different surface gravity features and the internal compositional structures of the Earth, Moon and the Sun acquired during the Hadean. Examples of lithospheric movements, rifting, subduction and the continued mantle-crust interaction from Indian and Southeast Asian geology would bring the readers close to interlinking these tectonic processes to the genesis of igneous, sedimentary and metamorphic rocks as well as to the episodes of mineralizations. Emphasizing these dynamic processes, the text focuses on the constitution of oceans, the causes of mass extinctions and the evolution of life forms, the biogeochemical cycles of elements, and also, on the life protecting ozone layer of the stratosphere, all unique to the Earth System. The student is sensitized towards the natural hazards of frequent volcanic eruptions, earthquakes, tsunamis, floods, and climate change besides explicating the threats posed by global warming, atmospheric and hydrosphere pollution, caused by the industrial emanations and indiscrete waste disposal. KEY FEATURES • Each chapter is replete with examples, illustrations, tables and figures to make reading more fruitful and enriching. • Chapter-end summary helps in recapitulation of the concepts discussed. • Additional Reading provided at the end of each chapter directs the readers to the vast source of information. NEW TO THE FOURTH EDITION Considering the growing global interest in locating a habitable exoplanet like the Earth, and in exploring the Moon and the Mars, the present edition thoroughly updates the information about • the geochemical processes, unique to the Earth System, that gave rise to the life supportive crust, oceans and the atmosphere. • the role played by plate tectonics in forming the igneous, sedimentary and metamorphic rocks, mineral deposits, and also, in the evolution of life. • the geo-environmental hazards of volcanic eruptions, earthquakes, floods, tsunamis, droughts and desertification. • the growing adoption of solar, hydro, wind and nuclear energy in power generation, and in management of clean environment. TARGET AUDIENCE • M.Sc. (Geology, Applied Geology, Geoinformatics, Geophysics, Geochemistry, Geography, Earth Science, and Environmental Science) • B.Sc. (Geology, Applied Geology)
Metal Deposits in Relation to Plate Tectonics by Frederick J. Sawkins Pdf
