This book was released on 1990-02-28 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: Featuring over 250 contributions from more than 100 earth scientists from 18 countries, The Encyclopedia of Igneous and Metamorphic Petrology deals with the nature and genesis of igneous rocks that have crystallized from molten magma, and of metamorphic rocks that are the products of re-crystallization associated with increases in temperature and pressure, mainly at considerable depths in the Earth's crust. Entries range from alkaline rocks to zeolite facies - providing information on the mineralogical, chemical and textural characters of rock types, the development of concepts and the present state of knowledge across the spectrum of igneous and metamorphic petrology, together with extensive lists of both commonly used and little used terms and bibliographies.

This book was released on 2008-10-14 with total page 1250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrothermal processes on Earth have played an important role in the evolution of our planet. These processes link the lithosphere, hydrosphere and biosphere in continuously evolving dynamic systems. Terrestrial hydrothermal processes have been active since water condensed to form the hydrosphere, most probably from about 4.4 Ga. The circulation of hot aqueous solution (hydrothermal systems) at, and below, the Earth’s surface is ultimately driven by magmatic heat. This book presents an in-depth review of hydrothermal proceses and systems that form beneath the oceans and in intracontinental rifts, continental margins and magmatic arcs. The interaction of hydrothermal fluids with rockwalls, the hydrophere and the biophere, together with changes in their composition through time and space, contribute to the formation of a wide range of mineral deposit types and associated wallrock alteration. On Earth, sites of hydrothermal activity support varied ecosystems based on a range of chemotrophic microorganisms both at surface and in the subsurface. This book also provides an overview of hydrothermal systems associated with meteorite impacts and explores the possibility that hydrothermal processes operate on other terrestrial planets, such as Mars, or satellites of the outer planets such as Titan and Europa. Possible analogues of extraterrestrial putative hydrothermal processes pose the intriguing question of whether primitive life, as we know it, may exist or existed in these planetary bodies. Audience: This volume will be of interest to scientists and researchers in geosciences and life sciences departments, as well as to professionals and scientists involved in mining and mineral exploration.
Download or read book Hydrothermal Processes Above the Yellowstone Magma Chamber written by Lisa A. Morgan and published by Geological Society of America. This book was released on 2009-01-01 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Home to more than 10,000 thermal features, Yellowstone has experienced over 20 large hydrothermal explosions producing craters from 100 to over 2500 meters in diameter during the past 16,000 years. Using new mapping, sampling, and analysis techniques, this volume documents a broad spectrum of ages and geologic settings for these events and considers additional processes and alternative triggering mechanisms that have not been explored in previous studies. Although large hydrothermal explosions are rare on the human time scale, the potential for future explosions in Yellowstone is not insignificant, and events large enough to create a 100-m-wide crater might be expected every 200 years. This work presents information useful for determining the timing, distribution, and possible causes of these events in Yellowstone, which will aid in the planning of monitoring strategies and the anticipation of hydrothermal explosions."--Publisher's description.

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.

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.

Book excerpt: Empirical Metallogeny: Depositional Environments, Lithologic Associations, and Metallic Ores, Vol. 1: Phanerozoic Environments, Associations, and Deposits, Part B focuses on the composition, characteristics, properties, and reactions of Phanerozoic metallic ore deposits. The book first offers information on intracrustal and subcrustal environments and plutonic granite, diorite, (gabbro) association (GDG) and its aureole. Discussions focus on petrography, origin, and setting of GDG plutonic rocks; mineralization styles associated with Phanerozoic (higher-level) granite, diorite, (gabbro) association; copper skarns and carbonate replacements; and magnetite skarn and replacement deposits. Manganese, uranium, antimony, mercury, and arsenic deposits, hydrothermal iron ores, and hydrothermal-plutonic silver deposits are also discussed. The publication also takes a look at high- to medium-grade metamorphosed terrains, katazonal granites and pegmatites and continental fragmentation, rifts, and paleo-rifts. Topics include examples of modern rift and taphrogenic systems; mineralization styles in and related to the zone of ultrametamorphism and granitization; and petrography, origin, and setting of high-grade metamorphic terrains. The text is a valuable reference for readers interested in the study of Phanerozoic metallic ore deposits.

Available in PDF, EPUB and Kindle. Book excerpt: This is the most comprehensive, all-embracing, single source of data on metallic deposits and their worldwide distribution. With over 1,750 pages it contains: 594 figures illustrating ore styles and their setting; 113 tables providing concise but highly quantitative data on several thousand locality examples; 4 indexes (general, locality, genetic, metals) enabling rapid and thorough searches; and more than 2,000 references. This vast body of information on metallic ore deposits is arranged by environments in which they presently form or lithologic associations in which they occur. The organization of the book follows the approach employed in regional mineral-potential evaluation and exploration. Long-lasting, objectively observable host units and empirical indicators of ore presence are stressed. The coverage is balanced and truly worldwide, based on original literature consulted in over 30 languages and on the author's personal familiarity with more than 2,000 ore deposits located in 85 countries. The book is a must for practising exploration geologists, petrologists, and economic geologists, as well as for specialists in various other branches of geology (e.g. glacial geologists, carbonate sedimentologists, volcanologists, and geochemists). Teachers and students will find this most complete data sourcebook an ideal supplement to the theory and basic data found in textbooks.
