"A fine treatment of this critical time in geology's history. Although it goes against our standard histories of the field, Laudan defends her views convincingly. Her style is direct, with carefully reasoned personal opinions and interpretations clearly defined."--Jere H. Lipps, "The Scientist"

This book discusses recent developments in dam engineering, covering theoretical as well as practical aspects. The chapters provide detailed descriptions of the types, surveys and investigations, layouts, design, thermal stresses and foundation of dams. The differences between various theories/methods of analysis used in design and their practical application and limitations are clarified. The book focuses on earth fills and landfills and stresses the importance of the foundation treatment. Failure of embankment dams is discussed particularly in the planning and construction stages of the dam. The environmental impact of dams is treated with references to river diversions and reservoir sedimentation. The book is written as a reference book for professional engineers and is also suitable for post graduate courses.

This book provides a comprehensive introduction to the field of geochemistry. The book first lays out the 'geochemical toolbox' the basic principles and techniques of modern geochemistry, beginning with a review of thermodynamics and kinetics as they apply to the Earth and its environs. These basic concepts are then applied to understanding processes in aqueous systems and the behavior of trace elements in magmatic systems. Subsequent chapters introduce radiogenic and stable isotope geochemistry and illustrate their application to such diverse topics as determining geologic time, ancient climates, and the diets of prehistoric peoples. The focus then broadens to the formation of the solar system, the Earth, and the elements themselves. Then the composition of the Earth itself becomes the topic, examining the composition of the core, the mantle, and the crust and exploring how this structure originated. A final chapter covers organic chemistry, including the origin of fossil fuels and the carbon cycle's role in controlling Earth's climate, both in the geologic past and the rapidly changing present.

"Geochemistry" is essential reading for all earth science students, as well as for researchers and applied scientists who require an introduction to the essential theory of geochemistry, and a survey of its applications in the earth and environmental sciences.

Geomicrobiology is the study of microbes and microbial processes and their role in driving environmental and geological processes at scales ranging from the nano, micron, to meter scale. This growing field has seen major advances in recent years, largely due to the development of new analytical tools and improvements to existing techniques, which allow us to better understand the complex interactions between microbes and their surroundings. In this comprehensive handbook, expert authors outline the state-of-the-art and emerging analytical techniques used in geomicrobiology. Readers are guided through each technique including background theory, sample preparation, standard methodology, data collection and analysis, best practices and common pitfalls, and examples of how and where the technique has been applied. The book provides a practical go-to reference for advanced students, researchers and professional scientists looking to employ techniques commonly used in geomicrobiology.

This is the first undergraduate textbook to fully integrate results from geophysics, geochemistry, and petrology to describe the structure, composition, and dynamic processes that operate throughout the solid Earth. It presents an Earth system science approach to studies of the Earth's interior and develops a global view of solid Earth cycles to explain geodynamic and plate tectonic processes. This book initially explores the formation and evolution of the early Earth, then considers the operative forces for plate tectonic movements at the Earth's surface, and finally discusses global cycles within the deep Earth and their effect on the surface environment. Interactions between the geosphere, hydrosphere, and atmosphere, and their influence at and beneath the Earth's surface are examined in detail. This textbook thus provides a concise yet extensive coverage of the solid Earth. Written for intermediate undergraduates, it includes a wealth of features to support student learning at this level.

The time-dependent decay of naturally occurring radioactive isotopes or in-growth of their radioactive or stable daughter products form the basis of radiometric dating of several natural processes. Developed in the beginning of the last century mainly to determine the absolute ages of rocks and minerals, radiometric chronology now plays a central role in a broad range of Earth and planetary sciences - from extra-solar-system processes to environmental geoscience. With the prerequisite of only college-level knowledge in physics, chemistry and mathematics, this concise book focuses on the essential principles of radiometric dating in order to enable students and teachers belonging to diverse fields of studies to select, understand and interpret radiometric dating results generated and published by professionals.

Consisting of papers that have appeared recently in International Geology Review, Middle American Terranes, Potential Correlatives, and Orogenic Processes focuses on Middle American terranes in which tectonic processes, including flat-slab subduction, for orogenic development are examined at various times since the late Mesoproterozoic: at 1 Ga, through the Paleozoic, and into the Cenozoic. Many papers relate the evolution of the Middle American terranes over the past billion years to global scale events, and a second theme running through the book relates to the supercontinents, Rodinia and Pangea, the geometry of their amalgamation and breakup, and the processes responsible. Highlights include: * An update on the geographic record, tectonic setting, and provenance of these terranes * Documentation of allocthonous nature and position peripheral to Amazonia of the ~1 Ga basement of southern Mexico * Data demonstrating that the basement rocks were involved in several Phanerozoic tectonic events * An examination of new evidence of a Late Paleozoic event associated with the amalgamation of Pangea overprinting the ~1 Ga basement and the Paleozoic units lying chiefly to the west and south of it * An exploration of the following potential correlatives: (1) events in Europe on the northern margin of Gondwana; (2) the Late Silurian-Devonian Acadian orogeny in the Appalachian, which is inferred to have resulted from flat-slab subduction related to overriding a plume; and (3) Mesozoic-Cenozoic events along the western margin of Laurentia * A discussion of possible mechanisms for the initiation of orogeny, flat-slab subduction in the Laramide orogeny, and hypotheses relating to the amalgamation and breakup of supercontine

The congress "Arsenic in the Environment" offers an international, multi- and interdisciplinary discussion platform for arsenic research aimed at practical solutions of problems with considerable social impact, as well as focusing on cutting edge and breakthrough research in physical, chemical, toxicological, medical and other specific issues on arsenic on a broader environmental realm. The congress "Arsenic in the Environment" was first organized in Mexico City (As 2006) followed by As 2008 in Valencia, Spain and As 2010 in Tainan, Taiwan. The 4th International Congress As 2012 was held in Cairns, Australia from July 22-27, 2012 entitled Understanding the Geological and Medical Interface of Arsenic. The session topics comprised: 1. Geology and hydrogeology of arsenic; 2. Medical and health issues of arsenic; 3. Remediation and policy; 4. Analytical methods for arsenic; and 5. Special topics on "Risk assessment of arsenic from mining", "Geomicrobiology of arsenic", "Geothermal arsenic", "Rice arsenic and health perspectives", "Sustainable mitigation of arsenic: from field trials to policy implications", and "Biogeochemical processes of high arsenic groundwater in inland basins" Hosting this congress in Australia was welcome and valued by the local scientific communities. Australia is a mineral rich country where mining has generated significant economic benefit to its people. Unfortunately historical mining for base metals, gold and arsenic had led to environmental contamination of arsenic. Locally produced arsenical compounds were widely used as pesticides and in timber preservation. It is known that there are several thousands of cattle- and sheep-dip sites contaminated with arsenic in Australia. However, commonly observed symptoms of chronic arsenic poisonings such as those found in endemic-blackfoot areas are seemingly absent from these types of environmental contamination due to good quality of potable water supply. Does this fall in the classic argument of "the dose makes the poison"? This congress theme of "understanding the geological and medical interface of arsenic" will advance our knowledge in minimising the risk posted by this so-called number one prioritised contaminant - arsenic.
