Download Stable Isotope Geochemistry Book in PDF, ePub and Kindle
This classic textbook is an introduction to the systematics and the use of stable isotopes in geosciences. It is subdivided into three parts: i) theoretical and experimental principles, ii) fractionation processes of light and heavy elements, iii) the natural variations of geologically important reservoirs. Since the publication of the previous edition improvements in multi-collector ICP mass-spectrometry have increased the ability to measure isotope ratios with very high precision for many elements of the periodic table. The amount of published data has increased tremendously in the last years; thus, conclusions based on a limited database are now better constrained. In this new edition, therefore, 47 elements with resolvable natural variations in isotope composition are discussed. This increase of elements, together with advances in the calculation of equilibrium isotope fractionation using ab initio methods, has led to an unbelievable rise of publications, making substantial major revisions and extensions of the last edition necessary. Many new references have been added, which enable quick access to recent literature.

Download Non-Traditional Stable Isotopes Book in PDF, ePub and Kindle
The development of multi-collector inductively coupled plasma mass spectrometry (MC-ICPMS) makes it possible to precisely measure non-traditional stable isotopes. This volume reviews the current status of non-traditional isotope geochemistry from analytical, theoretical, and experimental approaches to analysis of natural samples. In particular, important applications to cosmochemistry, high-temperature geochemistry, low-temperature geochemistry, and geobiology are discussed. This volume provides the most comprehensive review on non-traditional isotope geochemistry for students and researchers who are interested in both the theory and applications of non-traditional stable isotope geochemistry.

Download Compilation of Minimum and Maximum Isotope Ratios of Selected Elements in Naturally Occurring Terrestrial Materials and Reagents Book in PDF, ePub and Kindle
Documented variations in the isotopic compositions of some chemical elements are responsible for expanded uncertainties in the standard atomic weights published by the Commission on Atomic Weights and Isotopic Abundances of the International Union of Pure and Applied Chemistry. This report summarizes reported variations in the isotopic compositions of 20 elements that are due to physical and chemical fractionation processes (not due to radioactive decay) and their effects on the standard atomic weight uncertainties. For 11 of those elements (hydrogen, lithium, boron, carbon, nitrogen, oxygen, silicon, sulfur, chlorine, copper, and selenium), standard atomic weight uncertainties have been assigned values that are substantially larger than analytical uncertainties because of common isotope abundance variations in materials of natural terrestrial origin. For 2 elements (chromium and thallium), recently reported isotope abundance variations potentially are large enough to result in future expansion of their atomic weight uncertainties. For 7 elements (magnesium, calcium, iron, zinc, molybdenum, palladium, and tellurium), documented isotope-abundance variations in materials of natural terrestrial origin are too small to have a significant effect on their standard atomic weight uncertainties.

Download Distinguishing Primary Versus Secondary Geochemical and Silicon Isotope Characteristics of Precambrian Chert and Iron Formation Book in PDF, ePub and Kindle
Precambrian chert and banded iron formation (BIF) are defined as chemical sediments precipitated directly from seawater. As such, their geochemistry, including trace elements, rare earth elements (REE), and isotopes (O, Si) may preserve Precambrian seawater conditions. However, the chemical signature of these rocks may not simply reflect seawater, because hydrothermal interactions and metasomatism may produce rocks that petrographically and chemically resemble chert and BIF, including seawater-like compositional characteristics acquired during mineral replacement. Interpreting the major-, trace-, and rare-earth element signatures of these rocks requires the identification of geochemical and isotopic fingerprints that differentiate rocks formed from chemical sedimentation from rocks formed through replacement. Previously, REE proxies have been used to identify chemically precipitated sedimentary rocks such as chert. However, these established proxies have proven to be non-diagnostic in depositional settings where alteration has resulted in element mobility. Silicon isotopes, by contrast, have the potential to discriminate rocks formed by chemical sedimentation from those formed through replacement, because they record process-specific information concerning the mechanism of quartz precipitation. Of equal importance, silicon isotopes can provide key information that may identify marine silicon sources. Using information concerning what isotopic signatures can be preserved in quartz precipitates from different depositional settings, a compilation of the silicon isotope composition of chert can be deciphered to understand lithology-dependent trends. Archean-aged silicified rocks formed through replacement of primary minerals by quartz have a silicon-isotope composition similar to the original rock. Chemical sedimentary chert formed through quartz precipitation proximal to hydrothermal systems has a wide range of silicon-isotope compositions, and shows no apparent trend with respect to time. Only chemical sedimentary cherts associated with iron formation formed in continentally influenced depositional settings record a systematic trend with respect to time. These rocks record a unidirectional positive shift in silicon-isotope compositions. We interpret this trend to reflect chemical precipitation from a changing ocean reservoir, where, as a result of steady growth and emergence of continental masses, the ocean reservoir evolved from one dominated by a hydrothermal silicon isotope signature to a continental one.

Download Handbook of Environmental Isotope Geochemistry Book in PDF, ePub and Kindle
Applications of radioactive and stable isotopes have revolutionized our understanding of the Earth and near-earth surface processes. The utility of the isotopes are ever-increasing and our sole focus is to bring out the applications of these isotopes as tracers and chronometers to a wider audience so that they can be used as powerful tools to solve environmental problems. New developments in this field remain mostly in peer-reviewed journal articles and hence our goal is to synthesize these findings for easy reference for students, faculty, regulators in governmental and non-governmental agencies, and environmental companies. While this volume maintains its rigor in terms of its depth of knowledge and quantitative information, it contains the breadth needed for wide variety problems and applications in the environmental sciences. This volume presents all of the newer and older applications of isotopes pertaining to the environmental problems in one place that is readily accessible to readers. This book not only has the depth and rigor that is needed for academia, but it has the breadth and case studies to illustrate the utility of the isotopes in a wide variety of environments (atmosphere, oceans, lakes, rivers and streams, terrestrial environments, and sub-surface environments) and serves a large audience, from students and researchers, regulators in federal, state and local governments, and environmental companies.
