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.
Handbook of Environmental Isotope Geochemistry, Volume 1: The Terrestrial Environment, A focuses on isotope hydrology and aqueous geochemistry, as well as an overview of carbon, sulfur, and nitrogen isotopes in terrestrial systems. The selection first elaborates on the isotopes of hydrogen and oxygen in precipitation, carbon-14 in hydrogeological studies, and environmental isotopes in groundwater hydrology. Concerns cover groundwater dating, mechanism of salinization, groundwater recharge, models of the isotope fractionation during evaporation and condensation of water in the atmosphere, and stable isotope distribution in atmospheric waters. The book then examines environmental isotopes in ice and snow, isotopic evidence on environments of geothermal systems, and sulfur and oxygen isotopes in aqueous sulfur compounds. Discussions focus on geochemistry and isotope distribution of aqueous sulfur compounds, isotopic dating of geothermal waters, origin of chemical constituents, geothermometry, isotope distribution during the reduction of a temperate snow cover, and snow and ice isotope hydrology. The manuscript explores environmental isotopes as environmental and climatological indicators, sulfur isotopes in the environment, nitrogen-15 in the natural environment, and the isotopic composition of reduced organic carbon. The selection is a valuable reference for researchers interested in isotope geochemistry.
Developments in Geochemistry, Volume 3: Helium Isotopes in Nature presents the isotopic investigations of noble gases. This book describes the origin, the history, and the contemporary distribution of isotopes of helium. Organized into 11 chapters, this volume begins with an overview of mass-spectrometric methods and measurements of the helium isotope abundance. This text then discusses the methods of collecting various terrestrial samples as well as the apparatus for helium extraction, volumetric measurements, and purification. Other chapters consider the isotope composition of primordial, radiogenic, and spallogenic light noble gases. This book discusses as well the origin and distribution of helium isotopes in meteorites, in the Earth's mantle, the crust and ocean, and in the atmosphere. The final chapter deals with the scientific and applied problems that can be resolved to the progress in helium isotope geochemistry. This book is a valuable resource for scientists. Research workers and students interested in the geochemistry of helium will also find this book useful.
Handbook of Environmental Isotope Geochemistry, Volume 2: The Terrestrial Environment, B focuses on the processes, methodologies, principles, and approaches involved in isotope geochemistry. The selection first elaborates on mathematical models for the interpretation of environmental radioisotopes in groundwater systems; isotopes in cloud physics; and environmental isotopes in lake studies. Discussions focus on water balance studies of lakes, isotopic fractionations during evaporation of water, study of hailstone growth mechanisms by means of isotopic analyses, isotopic effects during growth of individual elements, and models and their hydrological significance. The text then takes a look at environmental isotope and anthropogenic tracers of lake sedimentation; stable isotope geochemistry of travertines; and isotope geochemistry of carbonates in the weathering zone. Topics include isotopic composition of carbonates in the weathering zone; reprecipitation processes in the weathering zone; isotopic composition of carbon and oxygen sources in the weathering zone; and geochemical conditions controlling travertine deposition. The manuscript also reviews radioactive noble gases in the terrestrial environment, isotope effects of nitrogen in the soil and biosphere, and oxygen and hydrogen isotope geochemistry of deep basin brines. The selection is a vital source of data for researchers interested in isotope geochemistry.
After the discovery that elements were commonly composed of isotopes, there developed a range of studies of the variability of isotopic compositions in Earth materials, which was able to add to our understanding of Earth processes and history. This collection of chapters from the Treatise on Geochemistry describes the range of isotopic studies. The chapters are grouped into the following categories: light stable isotopes, radiogenic tracers, noble gases and radioactive tracers. The first three groups depend on mass spectrometric measurements. The section on radioactive tracers employs both radioactive counting techniques and the newly developed accelerator mass spectrometric techniques.
This two-volume reference serves as a handbook containing a wealth of information for all isotope chemists working in a wide range of disciplines including anthropology to ecology; drug detection methodology to toxicology; nutrition to food science; and the atmospheric sciences to geochemistry.Complementing the first volume, Volume II includes matters that are not strictly confined to the analytical techniques themselves, but relate to analysis of stable isotopes, such as the views on the development of mass spectrometers, isotopic scales, standards and references, and directives for setting up a laboratory.ALSO AVAILABLE:Volume I: Dec. 2004, 0444511148/9780444511140, $176.00Volume I and II (set): Oct. 2007, 0444511164/9780444511164, $205.00
The contents of the book are assembled from selected papers presented during the International Conference on Isotopes in Environmental Studies – AQUATIC FORUM 2004 convened in Monaco from 25 to 29 October 2004, which was the most important gathering of the year of isotope environmental scientists. The book reviews the present state of the art isotopic methods for better understanding of key processes in the aquatic environment, responsible for its future development and its protection. The main highlights include the latest developments in the study of the behaviour, transport and distribution of isotopes in the aquatic environment, recent climate change records using isotopic tracers in the environment, global isotopic oceanic studies, new trends in radioecological investigations and modelling, impact of groundwater-seawater interactions on coastal zones, groundwater dynamics and modelling, important for management of freshwater resources, development of new isotopic techniques, such as AMS, RIMS and ICPMS, and their applications in environmental studies, new trends in radiometrics underground techniques, new in situ radiometrics technologies and many other exciting topics which were presented and discussed during the Conference. The proceedings constitute an important contribution to the environmental isotopic research. In publishing this book the aim is to make the use of isotopes more widespread in the environmental disciplines and to further stimulate work in this exciting field.
(Parent with price) Volume I contains subjective reviews, specialized and novel technique descriptions by guest authors. Part 1 includes contributions on purely analytical techniques and Part 2 includes matters such as development of mass spectrometers, stability of ion sources, standards and calibration, correction procedures and experimental methods to obtain isotopic fractionation factors.Volume II will be available in 2005.
Within the joint German-Russian research project "Siberian River Run-off (SIRRO)" multidisciplinary studies were carried out in the Ob and Yenisei estuaries and adjacent southern Kara Sea (Arctic Ocean). The overall goal of the project was to extend knowledge on understanding the freshwater and sediment input by the major Siberian rivers and its impact on the environments of the inner Kara Sea. The main results of oceanographical, biological, geochemical, geological and modelling studies are presented in four main chapters:(A) Modern Discharge: Data and modelling; (B) Discharge and biological processes, (C) Discharge and organic carbon cycle, and (D) Discharge and sediment records.
