The review chapters in this volume were the basis for a two-day short course on nontraditional stable isotopes held prior (May 15í16, 2004) to the spring AGU/CGU Meeting in Montreal, Canada. The editors (and conveners of the short course) Clark Johnson, Brian Beard and Francis Albarède and the other chapter authors/presenters have done an exceptional job of familiarizing us with the cutting edge of this exciting fi eld of study <...>

Recurring concerns about the environmental fate and potential health impacts of radionuclides such as 137CS, 90Sr, and 99Tc continue to focus interest on understanding the mechanisms controlling radionuclide transport in soils. At the same time, the difficulty and complexity of cleaning up radionuclide-contaminated soils highlights our inability to predict radionuclide transport in near surface environments. Nevertheless, new theories and novel analytical techniques are increasingly able to provide a picture of radiochemical reactivity in situ in soils at the molecular level. There is therefore the possibility that an atomic level view of contaminant binding to soils can provide a knowledge-based framework for choosing remedial targets, achieving cleanup, and protecting public health. Interest in such subjects led to a symposium entitled "Soil Geochemical Processes ofRadionuclides" that was held at the 1999 Soil Science Society of America Annual Meeting at Salt Lake City, UT. <...>

The geology and geochemistry of petroleum are becoming ever more important as the demand for fossil fuels increases worldwide. We must find new hydrocarbon reserves that are hidden in almost inaccessible areas. Our knowledge of petroleum geology and geochemistry is the best intellectual tool that we have for the neverending search for rich new deposits of hydrocarbons.

В книге рассматриваются масштабы пластовой и вертикальной миграции компонентов нефти и газа, отраженные в изменениях органического вещества и газовой составляющей подземных вод. Устанавливается сфера прогнозного действия прямых гидрогеохимическйх показателей нефтегазоносности и значительной мере определяется эффективность их практического использования на различных этапах и стадиях поисково-разведочных работ на нефть и газ. 

The volume ‘‘Environmental Geochemistry: Site Characterization, Data Analysis, Case Histories’’ contains selected papers presented at the ‘‘Workshop: Environmental Geochemistry—Site Characterization, Waste Disposal, Data Analysis, Case Histories’’ held in Napoli (Italy) on May 4–5, 2006. Participants from private and public institutions of Canada, Finland, Greece, Italy, the UK, and USA, took part.

Развитие экономики в ближайшие десятилетия будет обеспечиваться традиционными источниками энергии-нефтью и газом. Уменьшение темпа прироста запасов нефти и газа, связанное с сокращением открытий крупных месторождений, заставляет геологов-нефтяников обратиться к так называемым нетрадиционным объектам поисков нефти и газа, к каковым относятся углеродсодержа-щие еилициты и глинисто-кремнистые толщи.

The zone between land surface and the water table, which forms the upper boundary of  the groundwater region, is known as the vadose zone. This zone is mostly unsaturated—or more precisely, partially saturated—but it may contain a saturated fraction in the vicinity of the water table due to fluctuations in water levels or capillary rise above the water table.

Green Chemistry and the Ten Commandments of Sustainability, 2nd ed, was written to provide an overview of the emerging discipline of green chemistry along with the fundamental chemical principles needed to understand this science. The second edition follows the first edition published in 2004 under the title of Green Chemistry: Fundamentals of Sustainable Chemical Science and Technology, from which it differs by the inclusion of an additional chapter, Chapter 14, “The Ten Commandments of Sustainability.”

The oceans of the world represent a natural depository for the dissolved and particulate products of continental weathering. After its input, the dissolved material consolidates by means of biological and geochemical processes and is deposited on the ocean floor along with the particulate matter from weathered rock. The ocean floor deposits therefore embody the history of the continents, the oceans and their pertaining water masses.

This book contains a comprehensive presentation of all aspects of isotope geoscience and is intended to be used in universities and colleges as a textbook in lecture courses for senior undergraduate and first-year graduate students in the earth sciences. In addition, this book will serve as a source of information for professionals in the earth sciences and related disciplines. The encyclopedic function of this book is enhanced by a detailed table of contents and by author and subject indexes. The book also contains a large number of original diagrams with extended captions that facilitate browsing and convey information without requiring close reading of the text. In addition, each chapter contains cross-references to other parts of the book where related information can be found <...>
