Product Description
The field of geochemistry involves study of the chemical composition of the Earth and other planets, chemical processes and reactions that govern the composition of rocks and soils, and the cycles of matter and energy that transport the Earth's chemical components in time and space, and their interaction with the hydrosphere and the atmosphere. This book presents leading research in the field. ... Read more

Product Description
An ever-increasing concern over environmental degradation, together with recent technological advances, has spawned an explosion of chemical data for a wide variety of matter found on earth and in the solar system. Yuan-Hui Li's book offers professionals and students alike an indispensable up-to-date guide to geochemistry, bringing together new information on topics ranging from nucleosynthesis to crystal chemistry, from the systematics of chemical variation in the earth's core to the composition of complex organics. The objective is to illustrate the physicochemical principles and various natural processes that can explain observed compositional changes in natural substances. A general understanding of these principles and processes (including those pertaining to cosmology, geology, and biology) is essential, maintains the author, for deciphering and predicting transport pathways and final sinks of anthropogenic pollutants in our environment.

The book focuses on compositional data and related references for such substances as solar photosphere, meteorites, igneous rocks, soils, sedimentary rocks, surficial waters, marine and terrestrial organisms (including humans), and aerosols. It emphasizes the use of original raw data as much as possible, and applies the statistical technique of factor analysis to elucidate any underlying interrelationships among chemical elements and given sample sets. Whenever applicable, simple chemical thermodynamic models are introduced to explain the observed partitioning of elements among different phases. ... Read more

Product Description
Geochemistry uses the methods and philosophies of chemistry toexplore and understand the Earth from the most elementary levels. Thefield has moved on from a prehistoric interest in metals, chert andclay, to become a modern science, utilizing sophisticated techniquesto understand the Earth's processes and evolution. By looking deeplyinto the Earth's constituents, scientists are able to verify theorieson its formation and, by corollary, on the formation of other planetsin the universe. Because geochemistry involves intensive, detailedexaminations of pieces of the planet, the subject touches upon manyaspects of other scientific explorations, such as predicting earthtremors and volcanoes, the origin of life, environmental contaminationand waste management, and finding mineral and organic ores. The Encyclopedia of Geochemistry is a complete and authoritativereference text to this evolving field. Over 200 internationalscientists, each experts in their specialties, have written over 340separate topics on different aspects of geochemistry includingorganics, trace elements, isotopes, high and low temperaturegeochemistry and ore deposits, to name just a few. The instrumentsused to refine geochemical techniques are each described in detail,and the chemical elements have their own separate entries whichinclude common mineralogical, petrological and sedimentologicaldepictions. Each topic incorporates cross-referencing to related articles, andalso has its own reference list to lead the reader to the essentialarticles within the published literature. The entries are arrangedalphabetically, for easy access, and the subject and citation indicesare comprehensive and extensive. ... Read more

Product Description

This book is written by a leading authority on the subject of magmatic sulfide deposits. An overview of deposit types, accompanied by a summary of the resources of nickel, copper and platinum-group elements in the world’s principal known deposits, is followed by a summary of the relevant physical chemistry. The core of the book comprises a discussion about the geology and geochemistry of each of the deposit types in turn, accompanied by the implications of this data to the origin of the deposits in the light of our understanding of the chemical processes involved. A final chapter focuses on the use of the genetic concepts in exploration.

Product Description
The lithosphere is the outer solid part of the earth, including the crust and uppermost mantle. The lithosphere is about 100 km thick, although its thickness is age dependent (older lithosphere is thicker). The lithosphere below the crust is brittle enough at some locations to produce earthquakes by faulting, such as within a subducted oceanic plate. This book presents leading research in the field from around the globe. ... Read more

Product Description
Molecular markers are substances that serve as source indicators and process probes. This comprehensive collection examines the use of molecular markers in environmental geochemistry. It presents recent research on three classes of markers: contemporary biogenic markers, fossil biomarkers, and anthropogenic markers. ... Read more
