Download or read book Komatiite written by Nicholas Arndt and published by Cambridge University Press. This book was released on 2018-03-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Komatiites erupted billions of years ago as pulsating streams of white-hot lava. Their unusual chemical compositions and exceptionally high formation temperatures produced highly fluid lava that crystallized as spectacular layered flows. Investigation of the extreme conditions in which komatiites formed provides important evidence about the thermal and chemical evolution of the planet, and the nature of the Precambrian mantle. This monograph, written by three experts with long experience in the field, presents a complete account of the characteristics of komatiites including their volcanic structures, textures, mineralogy and chemical compositions. Models for their formation and eruption are evaluated (including the anhydrous vs. hydrous magmas controversy). A chapter is also devoted to the valuable nickel and copper ore deposits found in komatiites. Komatiite is a key reference for researchers and advanced students interested in petrology, Archaean geology, economic geology, and broader questions about the evolution of the Earth's crust and mantle.

Download or read book Volcanic Successions Modern and Ancient written by R. Cas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of our aims in the book is to provide geologists with a sound basis for making their own well founded interpretations. For that reason we cover not only concepts about processes, and the nature of the products, but also methods and approaches that may be useful in analysing both modern and ancient successions. Most importantly, we treat the diversity of products in volcanic terrains as facies, and we use the method of facies analysis and interpretation as a means of constructing facies models for different volcanic settings. These models will, we hope, be useful as norms for comparison for workers in ancient terrains. The idea for this book came into being between 1981 and 1982 when J. V. W. came to Monash University to take up a Monash Postdoctoral Fellowship. During this period a short course on facies analysis in modern and ancient successions was put together, integrating J.V.W.'s extensive volcanological experience in numerous modern volcanic terrains with R.A.F.C.'s extensive sedimentological and volcanological experience in older volcanic and associated sedimentary successions in the Palaeozoic and Precambrian of Australia. The enthusiastic response from the participants to the first short course, taught in May 1982, and to subsequent annual re-runs, encouraged us to develop the short course notes into this book. The idea for both the short course and the book arose because we felt that there was no single source available that comprehensively attempted to address the problems of analysing, interpreting and understanding the complexity of processes, products and stratigraphy in volcanic terrains.

Download or read book Ore Deposits and Mantle Plumes written by Franco Pirajno and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: PERTH Western Australia March 2000 Increasingly explorationists are seeking to find new ore deposits in poorly prospected areas, be they geographically remote, such as in the Arctic, or geologically remote, such as those under sedimentary cover. Modern prospecting techniques, including low-detection-level geochemistry and the use of advanced geophysical instrumentation have greatly assisted explorers but fundamental to any soundly based exploration program remains an understanding of the geological framework of ore deposits. This allows the development of deposit models on macroscopic and mesoscopic scales. This book by Dr. Franeo Pirajno draws on his extensive and wide global experience. To set the scene for a discussion of ore deposit generation Franeo details the Earths internal structures and mantle dynamics. He then explores the impact of mantle plumes on the crust and in particular their role in the production of magmatic environments, and in continental scale rifting. This includes a descriptive section on magmatic provinces around the globe, which highlights the importance of plumes. Any study of Earth processes needs to take into account the effects of extraterrestrial bombardment, and in particular the results from the impacts of large bolides. The effects of these impacts on the atmosphere and on life have now been recognised as profound. It is likely that the effect ofthese impacts on the Earth's crust is as equally profound.
Download or read book Magma Redox Geochemistry written by Roberto Moretti and published by John Wiley & Sons. This book was released on 2021-10-26 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explores the many facets of redox exchanges that drive magma's behavior and evolution, from the origin of the Earth until today The redox state is one of the master variables behind the Earth's forming processes, which at depth concern magma as the major transport agent. Understanding redox exchanges in magmas is pivotal for reconstructing the history and compositional make-up of our planet, for exploring its mineral resources, and for monitoring and forecasting volcanic activity. Magma Redox Geochemistry describes the multiple facets of redox reactions in the magmatic realm and presents experimental results, theoretical approaches, and unconventional and novel techniques. Volume highlights include: Redox state and oxygen fugacity: so close, so far Redox processes from Earth’s accretion to global geodynamics Redox evolution from the magma source to volcanic emissions Redox characterization of elements and their isotopes The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.
Download or read book Archean Base and Precious Metal Deposits Southern Abitibi Greenstone Belt Canada written by Thomas Monecke and published by . This book was released on 2017 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Abitibi greenstone belt of eastern Canada represents the world's largest Neoarchean terrane of supracrustal rocks. Straddling the border between the provinces of Ontario and Quebec, the belt covers an area that is approximately 700 km from southeast to northwest and 350 km from north to south. The belt is comprised of several major east-trending successions of folded volcanic and sedimentary rocks, with intervening intrusions. The supracrustal rocks of the Abitibi greenstone belt are uniquely well preserved and have mostly been overprinted only at a low metamorphic grade, allowing the study of primary geological relationships.
Download or read book Environmental Effects on Volcanic Eruptions written by James R. Zimbelman and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents current research into the effect that environmental conditions have on volcanic eruptions and the subsequent emplacement of volcanic products. This is accomplished through a series of chapters that investigate specific environments - both terrestrial and extraterrestrial - and the expression of volcanic materials found within those settings. Current state-of-the-art numerical, analytical and computer models are used in most chapters to provide robust, quantitative insights into how volcanoes behave in different environmental settings. Readership: Upper level undergraduates and new graduates. The book is primarily a presentation of research results rather than a tutorial for the general public. Textbook or supplementary reading for courses in volcanology or comparative planetology at college/university level.
