Download or read book Early Precambrian Basic Magmatism written by R.P. Hall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basic magmatic rocks make up approximately three-quarters of the crust ofthe present day Earth. Because we can observe and study the volcanic products of present day tectonic regimes comprehensively, we can shed light on ancient tectono-magmatic provinces, and thereby deduce the petrogenesis and evolution of the oldest basic rocks. This is the primary objective of this book. The book was conceived in order to provide a comprehensive review of the basic rocks produced during the first half of the Precambrian, i.e. the Archaean and early Proterozoic, to about 1.8 Ga years ago. Two major questions are addressed. First, what basic magmas were generated during the early Precambrian: were these magmas globally uniform, and to what extent were prevailing tectonic controls and compo sitions analogous to those of the present day? Clearly, this can be answered only by bringing together fundamental information about all relevant basic magmatic events. Second, is there any systematic temporal variation in the nature of basic suites, and what implications might such variations have on our interpretations of early Earth history? Are there important differences between early Archaean, late Archaean, Proterozoic and modern basic magmatic suites? The book uses two approaches to address these questions. Early chapters examine the fundamental characteristics of these basic rocks, whilst later chapters assess regional distribution and development by providing an overview of each major early Precambrian craton.

Available in PDF, EPUB and Kindle. Book excerpt: This volume draws together and generalises new geological, geochronological, petrological and geophysical material for the two fundamental continental geostructures within the USSR - ancient cratons and Phanerozoic fold belts. It provides a complete Precambrian history for each tectonic province or "geoblock", with emphasis on the early Precambrian as opposed to the late. The characteristics of lithological-structural complexes and their correlations are presented in detail. Analysis of the sedimentary, magmatic and metamorphic processes is provided, paying special attention to the sequence of their evolution and isotopic data. This work will be of interest to geologists concerned with the problems of structure and evolution of the Precambrian lithology.

Book excerpt: Magnatism is the only true endogenic process for generating new material on the Earth's surface. Obviously, magmatism and tectonic movements are reflections of geodynamics, that is, physical processes which occur in deep-seated environments. What are the interrelationships between magmatism and tectronics? How did the character of terrestrial magmatism change through time and are there any irregularities in this process?

Download or read book Reading the Archive of Earth s Oxygenation written by Victor Melezhik and published by Springer Science & Business Media. This book was released on 2012-10-22 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth’s present-day environments are the outcome of a 4.5 billion year period of evolution reflecting the interaction of global-scale geological and biological processes punctuated by several extraordinary events and episodes that perturbed the entire Earth system. One of the earliest and arguably greatest of these events was a substantial increase (orders of magnitude) in the atmospheric oxygen abundance, sometimes referred to as the Great Oxidation Event. Volume 1: The Palaeoproterozoic of Fennoscandia as Context for the Fennoscandian Arctic Russia - Drilling Earth Project describes the implementation of the FAR-DEEP drilling project in Arctic Russia. It summarises the knowledge of more than 50 years of largely Russian-led fieldwork, information hitherto virtually unavailable in the west, and provides geological description of drilling areas with an overwhelming illustration of rocks by high-quality, representative photographs. The volume offers a comprehensive review and rich photo-illustration of palaeotectonic, palaeogeographic and magmatic evolution of the Fennoscandian Shield in the early Palaeoproterozoic, and link the evolution of the shield to the emergence of an aerobic Earth system. The volume unfolds the event-based Fennoscandian chronostratigraphy and discusses the chronology of the Palaeoproterozoic global events as the base for a new subdivision of Palaeoproterozoic time. Welcome to the illustrative journey through one of the most exciting periods of planet Earth!

Available in PDF, EPUB and Kindle. Book excerpt: Like N. O. Sorokhtin’s most recent book, The Origins of Natural Diamonds, also available from Wiley-Scrivener at www.wiley.com, this is not just the story of the origin and evolution of the Baltic Shield, but a story about the evolution of the Earth’s geology in general. Important to geologists, geophysicists, and engineers across multiple disciplines, written by an expert in the field and an expert on the Earth’s geological evolution, this volume represents the state-of-the-art in major Earth geological processes. Of particular importance to mining engineers and petroleum engineers, it is also a practical guide for those who work in the mining or petroleum industry. Before presenting the most in-depth discussion of the Baltic Shield available and its implications for study by geologists and various industries such as the petroleum industry, the author presents a theory for how the Earth, as we know it, came into existence and developed. He bases this theory on scientific evidence and mathematical models, using this as a basis for further explanation of the Earth’s geological evolution. Valuable as either a learning tool for the student or as a reference or refresher for the veteran scientist or engineer, the author explains important geological processes, such as the Earth’s origin, composition, and structure, the Earth’s energy balance, continental drift, tectonic activity, the evolution of the Earth’s crust, and others. It is within this geological framework that the author offers practical guidance for engineers and scientists who work in industry or academia. It is a must-have for any geologist, geophysicist, or engineer working in mining or petroleum engineering.

Download or read book Isotope Geochemistry written by Vladimir Kuleshov and published by Elsevier. This book was released on 2016-09-13 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Isotope Geochemistry: The Origin and Formation of Manganese Rocks and Ores is a comprehensive reference on global manganese deposits, including their origins and formations. Manganese is both a significant industrial chemical, critical for steel-making, and a strategic mineral, occurring in abundance only in certain countries. Furthermore, it is used effectively in CO2 sequestration, helping to mitigate greenhouse gas emission challenges around the world. For these reasons, exploration for manganese is very active, yet access to the primary academic literature can be a challenge, especially in field operations. Isotope Geochemistry brings this material together in a single source, making it the ideal all-in-one reference that presents the supporting data, analytics, and interpretation from known manganese deposits. This book is an essential resource for researchers and scientists in multiple fields, including exploration and economic geologists, mineralogists, geochemists, and environmental scientists alike. - Features coverage of the formation, origins, and deposits of manganese rocks and ores globally, arming geoscientists with a thorough reference on the subject - Includes 170 figures and illustrations that visually capture key concepts - Includes elusive data with supporting analysis and interpretation of deposits in Russia, one of the most robust geographic locations in the world for manganese rock and ore research

Download or read book Archaean Geochemistry written by A. Kröner and published by Springer. This book was released on 2011-12-06 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Archaean Geochemistry 1972 - 1984 The realisation that the continental crust contains well-preserved relics which date as far back as 4/5 of the Earth's age has given a great impetus to the study of early Precambrian terrains. As late as the mid-sixties the Archaean still constituted the 'terra-in cognita' of earth science. High metamorphic grades, poor out crop, and not least a widely assumed obliteration of early crustal records by convective recycling and thermal reworking had com bined to discourage research in this field. Many excellent local studies existed, notably around gold mining centres, but remained unrelated to a broader regional and theoretical understanding. This situation has changed as the consequence of two inter-related factors: (1) advances in isotopic methods and their application to Precambrian rocks, and (2) the recognition that some of the oldest terrains have retained a wealth of primary igneous and sedi mentary textures and even geochemical characteristics.

Available in PDF, EPUB and Kindle. Book excerpt: From 1999 to 2003 a multipurpose regional geochemical mapping project, was carried out in Finland, and the NW-part of Russia. An important aim of the project is to define the anthropogenic impact in relation to the natural variations in regional geochemical baselines of heavy metals and other elements over a large area containing several of the largest industrial emitters in Europe but also some of its most pristine areas. Terrestrial moss, the organic layer, stream waters, and the C-horizon soil samples were collected from1085 sites in Russia and 288 sites in Finland, giving an average density of one site per 1000 km2. Both total and aqua regia extractable element concentrations were determined from 2 mm fraction of minerogenic samples, and total concentrations of organic soil samples and terrestrial moss were measured after strong acid leach, bioavailable concentrations of organic layer soil samples were measured, too. Concentrations of more than 50 elements, radionuclides, and other parameters were determined. Different extraction methods were used in order to study the speciation and bioavailability of the elements./pbrbrpMaps showing the distribution of 48 elements and other parameters are included in this atlas. The anomaly patterns of minerogenic C-horizon data are strongly controlled by element distributions in the bedrock. Stream water data are mainly controlled by geological formations and structures both for major and trace elements, but in some cases the influence of anthropogenic activities could be detected as elevated heavy metal concentrations. Anomaly patterns from moss data reflect mainly anthropogenic activities, but in areas such as mountains and tundra the geogenic dust also has a strong influence. It was not possible to detect any long distance airborne transport of heavy metals from industrialized areas to clean arctic regions.

Download or read book Terrestrial Heat Flow in Europe written by V. Cermak and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The outflow of heat from the earth's interior, the terrestrial heat flow, and the temperature field at depth are determined by deep-seated tectonic processes. The knowledge of the re gional heat flow pattern is thus very important in geophysics and provides a useful tool for studying crustal and litho spheric structure and understanding the nature of their evo lution. In order to use the results of heat flow measurements for regional studies and/or to correlate the observed surface geothermal activity with other geophysical or geological fea tures, a map showing the surface distribution of heat flow is necessary. Since 1963, when the first comprehensive listing of all available heat flow data appeared (Lee, 1963), several at tempts have been made to up-date the list, to classify all the data and to interpret them with respect to tectonics, deep structure and to use them for constructing surface heat flow maps. The first listing was subsequently revised by Lee and Uyeda (1965); numerous new data which were published there after were included in successive catalogs compiled by Simmons and Horai (1968) and then again by Jessop et al. (1976). The map showing the surface heat flow pattern may also be of great value for practical purposes, in view of the recent world-wide search for applicable sources of geothermal energy.

Download or read book Large Igneous Provinces and their Plumbing Systems written by R. K. Srivastava and published by Geological Society of London. This book was released on 2022-03-15 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identification of large-volume, short-duration mafic magmatic events of intraplate affinity in both continental and oceanic settings on the Earth and other planets provides invaluable clues for understanding several vital geological issues of current concern. Of particular importance is understanding the assembly and dispersal of supercontinents through Earth’s history, dramatic climate change events including mass extinctions, and processes that have produced a wide range of large igneous province (LIP)-related resources, such as Ni–Cu–PGE, Au, U, base metals and petroleum. This volume comprises 21 contributions on the latest developments and new information on LIPs and their plumbing systems and presents methodical studies on different components of LIP plumbing systems. These articles are especially helpful in understanding continental break-up events, regional domal uplift and a variety of metallogenic systems, as well as the temporal and spatial distribution of LIPs, their origin and their likely links to mantle plumes/superplumes.
