The book summarizes the results of the experimental studies of phase relations in the chemical systems relevant to Earth, carried out by the author in a time period of over 20 years between 1979 and 2001. It is based on 1000 piston-cylinder experiments at pressures up to 4 GPa, and close to 700 experiments carried out with a multi-anvil apparatus at pressures up to 24 GPA. This is the largest published collection of calculated phase diagrams for the chemical systems relevant to Earth. This is also the first time that the phase relations at the relatively low pressures of the lithospheric mantle, mainly applicable to the experimental thermobarometry of metamorphic rocks and mantle xenoliths, are seamlessly integrated with the phase relations of the sublithospheric upper mantle and the uppermost lower mantle, primarily applicable to inclusions in diamond and schocked meteorites. "Tibor Gasparik has devoted his career to determining the high-pressure, high-temperature phase relations of the geologically important Sodium-Calcium-Magnesium-Aluminium-Silicon (NCMAS) oxide system. This book is his opus magnum, summarizing more than 1700 experiments in over 120 figures. ... I have found Phase Diagrams for Geoscientists to be a useful first port-of-call for finding the P-T stability fields ... and I can recommend the book as a reference for geoscientists requiring an overview of the stable phase assemblages in the top 700 km of the Earth." (David Dobson, Geological Magazine, Vol. 142 (2), 2005)
Recent studies indicate that - due to climate change - the Earth is undergoing rapid changes in all cryospheric components, including polar sea ice shrinkage, mountain glacier recession, thawing permafrost, and diminishing snow cover. This book provides a comprehensive summary of all components of the Earth's cryosphere, reviewing their history, physical and chemical characteristics, geographical distributions, and projected future states. This new edition has been completely updated throughout, and provides state-of-the-art data from GlobSnow-2 CRYOSAT, ICESAT, and GRACE. It includes a comprehensive summary of cryospheric changes in land ice, permafrost, freshwater ice, sea ice, and ice sheets. It discusses the models developed to understand cryosphere processes and predict future changes, including those based on remote sensing, field campaigns, and long-term ground observations. Boasting an extensive bibliography, over 120 figures, and end-of-chapter review questions, it is an ideal resource for students and researchers of the cryosphere.
Ultrahigh Pressure Metamorphism (UHPM) is a fast growing discipline
that was established 25 years ago after discoveries of high
pressure minerals, coesite and diamonds. The current explosion of
research on UHMP terranes reflects their significance for
understanding large scale mantle dynamics, major elements of plate
tectonics such as continental collisions, deep subduction and
exhumation, mountains building, geochemical recycling 'from surface
to the core', and a deep storage of light elements participating in
green-house effects in the atmosphere. This book provides insights
into the formation of diamond and coesite at very high pressures
and explores new ideas regarding the tectonic setting of this style
of metamorphism.
In 1830-33, Charles Lyell laid the foundations of evolutionary biology with Principles of Geology, a pioneering book that Charles Darwin took with him on the Beagle. Volume 1 discusses the effects on the Earth's crust of climate change, running water, volcanic eruptions and earthquakes, and supports James Hutton's theory of uniformitarianism, now a guiding principle of geology. Volume 2 (1832) focuses on plants and animals, their distribution, diffusion, migrations and adaptation to changing habitats, and considers the theories of Lamarck, while Volume 3 periodises sedimentary and volcanic rock formations and considers the marine fossil record. The books are generously illustrated and thoroughly indexed. Lyell writes with infectious enthusiasm, conveying the excitement of his fieldwork and discoveries in this landmark book, which remains of interest to geologists and historians of science alike.
The second edition of Beaches of the New South Wales Coast has been rewritten and expanded. It covers all of the state's 757 open coast beaches, as well as 120 beaches in five large bays, including Sydney Harbour, and the 15 beaches on Lord Howe Island - 892 beaches in all. It also covers 276 of NSW top surfing sites. This book has two aims. First, to provide the public with general information on the origin and nature of all NSW beaches, including the contribution of geology, oceanography, climate and biota to the beaches, and information on beach hazards and safety. Second, to provide a description of each beach, including its name(s), location, access, facilities, dimensions and the character of the beach and surf zone. The book comments on the suitability of the beach for bathing, surfing and fishing, with special emphasis on the natural hazards. Based on the physical hazards, all beaches are rated in terms of public safety and scaled from 1 (least hazardous) to 10 (most hazardous).
This encyclopedia, which constitutes a wide ranging and authoritative collection of academic articles, covers the sedimentological aspects of sediments and sedimentary rocks. As such the encyclopedia provides a comprehensive, one-volume reference work for students and faculty in universities, and for professionals in geology and allied disciplines (geography, engineering, environmental studies), as well as informed lay readers.
Landslides occur in all geographic regions of the nation in response to a wide range of conditions and triggering processes that include storms, earthquakes, and human activities. Landslides in the United States result in an estimated average of 25 to 50 deaths annually and cost $1 to 3 billion per year. In addition to direct losses, landslides also cause significant environmental damage and societal disruption. Partnerships for Reducing Landslide Risk reviews the U.S. Geological Survey's (USGS)National Landslide Hazards Mitigation Strategy, which was created in response to a congressional directive for a national approach to reducing losses from landslides. Components of the strategy include basic research activities, improved public policy measures, and enhanced mitigation of landslides. This report commends the USGS for creating a national approach based on partnerships with federal, state, local, and non-governmental entities, and finds that the plan components are the essential elements of a national strategy. Partnerships for Reducing Landslide Risk recommends that the plan should promote the use of risk analysis techniques, and should play a vital role in evaluating methods, setting standards, and advancing procedures and guidelines for landslide hazard maps and assessments. This report suggests that substantially increased funding will be required to implement a national landslide mitigation program, and that as part of a 10-year program the funding mix should transition from research and guideline development to partnership-based implementation of loss reduction measures.

"Rivers and Floodplains" is concerned with the origin, geometry, water flow, sediment transport, erosion and deposition associated with modern alluvial rivers and floodplains, how they vary in time and space, and how this information is used to interpret deposits of ancient rivers and floodplains. There is specific reference to the types and lifestyles of organisms associated with fluvial environments, human interactions with rivers and floodplains, associated environmental and engineering concerns, as well as the economic aspects of fluvial deposits, particularly the modeling of fluvial hydrocarbon reservoirs and aquifers. Methods of studying rivers and floodplains and their deposits are also discussed. Although basic principles are emphasized, many examples are detailed. Particular emphasis is placed on how an understanding of the nature of modern rivers and floodplains is required before any problems concerning rivers and floodplains, past or present, can be addressed rationally. "Rivers and Floodplains" is designed as a core text for senior
undergraduate and graduate students studying modern or ancient
fluvial environments, particularly in earth sciences, environmental
sciences and physical geography, but also in civil and agricultural
engineering. College teachers, researchers, and practising
professionals will also find the book an invaluable
reference. "Rivers and Floodplains" will also be of interest to geologists, geographers and engineers.
The last decade has been a period of rapid advances in glacier hydrology and hydrochemistry. These have resulted from the application of new technologies to the direct observation of englacial and subglacial drainage systems via boreholes, from theoretical advances and from increased interactions between fieldworkers and modellers. This collection of papers captures the spirit of these advances highlighting new methodologies, the change in character of hydrological models from lumped conceptual models to physically based, distributed models, and the changing role of field studies in glacier hydrological investigations. Major themes identified in the book are: approaches to defining the structure of drainage systems in cold and temperate glaciers; investigations of the linkages between surface and subsurface components of these systems, and of hydraulic interactions between different elements of subglacial systems; seasonal changes in drainage system properties at local and glacier wide scales; controls on meltwater quality; the integration of field and modelling studies; and problems of scaling up results from studies of valley glaciers to the ice sheet scale.
Glacially triggered faulting describes movement of pre-existing faults caused by a combination of tectonic and glacially induced isostatic stresses. The most impressive fault-scarps are found in northern Europe, assumed to be reactivated at the end of the deglaciation. This view has been challenged as new faults have been discovered globally with advanced techniques such as LiDAR, and fault activity dating has shown several phases of reactivation thousands of years after deglaciation ended. This book summarizes the current state-of-the-art research in glacially triggered faulting, discussing the theoretical aspects that explain the presence of glacially induced structures and reviews the geological, geophysical, geodetic and geomorphological investigation methods. Written by a team of international experts, it provides the first global overview of confirmed and proposed glacially induced faults, and provides an outline for modelling these stresses and features. It is a go-to reference for geoscientists and engineers interested in ice sheet-solid Earth interaction.
The newspaper advertisement for volunteers to accompany Ernest Shackleton on his planned traverse of Antarctica in 1914 was frank in its offering. "Men wanted for hazardous journey. Low wages, bitter cold, long hours of complete darkness. Safe return doubtful. Honour and recognition in event of success." Still, hundreds applied. There were few chances left to be the first to reach the last challenge on Earth. As the 20th Century came of age, explorers had uncovered most of the world's mysteries, sailing to the far corners of the globe, ascending many of its most forbidding peaks, crossing its greatest deserts and penetrating its thickest jungles. Frozen, alien, inhospitable, dangerous, and close to impossible to reach, there were only two tiny dots on the globe that human beings had not yet set foot on--the North and South Poles. The Greatest Polar Exploration Stories Ever Told is a visceral, exciting and stunning collection of twelve stories recounting the bravery, resoluteness, and strength of the men who willingly traversed frozen hells to be the first to reach the North or South Pole. It is a collection that will both inspire and inform--and answer questions about the limits of human endurance. Many men would die during their challenging, frozen journeys, and their deaths were not pleasant. Yet they continued to try again. Here are stories, wrought by the challenging landscape and weather, that made these explorers household names and heroes: Peary, Scott, Amundsen, Shackleton, Franklin, Cherry-Garrard, Scott, Kane, Cook--and others lost to history whose bravery was nonetheless as admirable. Each of these men knew success would bring glory for their countries and financial security and fame and eminent places in history for themselves. Each knew also the odds of success were slim and the chance of dying great. Nations held their collective breaths for news of each expedition and those years later were termed the Heroic Age of Exploration--there were simply no other endeavors that captured the world's attention the various races to the poles. The Greatest Polar Exploration Stories Ever Told recaptures the spirit, drama, and tragedy of a time in history that will never come again.
The main mesological factors that determine vegetation activity are moisture and temperature (Ferreras Chasco, 2000). Under certain conditions of moisture and temperature a limitation in growth can appear and, if these conditions do not improve, plants can enter into a state called vegetative paralysis. This book discusses the land surface of the basin of the Guadaira River, and it pays attention to the study of riparian vegetation on different channels that belong to its countryside stretch. It also presents research on the modern spatiotemporal variability of the morphology of High Arctic proglacial rivers; and provides a review on the general properties of ancient Martian systems, focusing on possible issues related to the lack of biogenic effects on Mars, and analysing mainly riverbank related erosional and depositional structures.
This book is in response to the growing demand from academics and the general public for state-of-the-art research in permafrost science and, in particular, information about its impacts on infrastructure and ecosystems. It brings together research from diverse but highly complementary scientific disciplines to illuminate the main physical, chemical and biological processes occurring in permafrost systems and identifies the possible mechanisms controlling fluxes of energy and matter at various scales. Taken together, the 8 chapters of this book provide a comprehensive, up-to-date description and analysis of the basic geomorphological, physical, hydrological, chemical and biological aspects of permafrost-affected ecosystems, their interaction with other components of the landscape and their impact on human life and infrastructure.
This book provides a broad perspective of sediment transport in rivers, reservoirs, estuaries, and coastal areas. It deals with the related fundamentals of sediment transport, computational modelling of cohesive and non-cohesive sediments transport, and sedimentation engineering management. Topics include river morphological changes after dam removal, local scour and its monitoring, marsh edge erosion, turbidity dynamics in a bay surrounded by marshes, effects of harbour construction on hydrodynamic and morphodynamic processes in a coastal area, and impact of climate change on sediment yield from a watershed, are discussed. The breath of the topics covered will be of interest to researchers and practising engineers alike. This book contains twelve chapters.
The Anthropocene is a major new concept in the Earth sciences and this book examines the effects on geomorphology within this period. Drawing examples from many different global environments, this comprehensive volume demonstrates that human impact on landforms and land-forming processes is profound, due to various driving forces, including: use of fire; extinction of fauna; development of agriculture, urbanisation, and globalisation; and new methods of harnessing energy. The book explores the ways in which future climate change due to anthropogenic causes may further magnify effects on geomorphology, with respect to future hazards such as floods and landslides, the state of the cryosphere, and sea level. The book concludes with a consideration of the ways in which landforms are now being managed and protected. Covering all major aspects of geomorphology, this book is ideal for undergraduate and graduate students studying geomorphology, environmental science and physical geography, and for all researchers of geomorphology.
Weathering is an important phenomenon of the geochemical cycle as it contributes to the relief formation. It corresponds to a general term applied to physical and chemical changes suffered by rocks as a consequence of their exposition to different conditions of humidity and temperature. In this book, the authors present topical research in the study of the types, processes and effects of weathering. Topics discussed include the use of weathering indices in rock research; geomorphic processes in the last glacial age; understanding chemical weathering in affecting the Earth's surface; weathering of dimensional granite stones used as cladding and the weathering process and desert pavement development.
An aquifer is an underground layer of water-bearing permeable rock or unconsolidated materials (gravel, sand, silt, or clay) from which groundwater can be usefully extracted using a water well. The authors of this book present important data on aquifers such as: hydrogeological studies of various dolomite aquifers in Slovenia; (GIS)groundwater modelling as an integrated tool for sustainable management of groundwater resources under changing environments; investigating different groundwater systems occurring in Brazil; an analysis of past catastrophic hydrogeological events (landslides and floods) and their affect on groundwater and aquifers and how to mitigate their damage.
Sandstones form the backdrop to some of the world's most spectacular scenery, and are found all over the planet and in all climates. Following on from the authors' successful 1992 book, this is the only volume that considers sandstone landforms from a truly global perspective. It describes the wide variety of landforms that are found in sandstone, and discusses the role of lithological variation, chemical weathering and erosional processes in creating these features, with examples drawn from around the world. Climatic and tectonic constraints on the development of sandstone landscapes are also considered. This volume provides a comprehensive assessment of the literature from publications in a range of languages, and is illustrated with over 130 photographs of sandstone features from every continent. It presents a holistic account of sandstone terrain for researchers and graduate students in a variety of fields including geography, geomorphology, sedimentology and geomechanics.
'Outstanding Academic Title' Choice, magazine of the Association of College & Research Libraries, American Library Association.Most mountains on Earth occur within relatively well-defined, narrow belts separated by wide expanses of much lower-lying ground. Their distribution is not random but is caused by the now well-understood geological processes of plate tectonics. Some mountains mark the site of a former plate collision - where one continental plate has ridden up over another, resulting in a zone of highly deformed and elevated rocks. Others are essentially volcanic in origin.The most obvious mountain belts today - the Himalayas, the Alps and the Andes, for example - are situated at currently active plate boundaries. Others, such as the Caledonian mountains of the British Isles and Scandinavia, are the product of a plate collision that happened far in the geological past and have no present relationship to a plate boundary. These are much lower, with a generally gentler relief, worn down through millennia of erosion.The presently active mountain belts are arranged in three separate systems: the Alpine-Himalayan ranges, the circum-Pacific belt and the mid-ocean ridges. Much of the Alpine-Himalayan belt is relatively well known, but large parts of the circum-Pacific and ocean-ridge systems are not nearly as familiar, but contain equally impressive mountain ranges despite large parts being partly or wholly submerged.This book takes the reader along the active mountain systems explaining how plate tectonic processes have shaped them, then looks more briefly at some of the older mountain systems whose tectonic origins are more obscure. It is aimed at those with an interest in mountains and in developing an understanding of the geological processes that create them.
Allow yourself to be taken back into deep geologic time when strange creatures roamed the Earth and Western North America looked completely unlike the modern landscape. Volcanic islands stretched from Mexico to Alaska, most of the Pacific Rim didn't exist yet, at least not as widespread dry land; terranes drifted from across the Pacific to dock on Western Americas' shores creating mountains and more volcanic activity. Landscapes were transposed north or south by thousands of kilometers along huge fault systems. Follow these events through paleogeographic maps that look like satellite views of ancient Earth. Accompanying text takes the reader into the science behind these maps and the geologic history that they portray. The maps and text unfold the complex geologic history of the region as never seen before. Winner of the 2021 John D. Haun Landmark Publication Award, AAPG-Rocky Mountain Section
Salt marshes are highly dynamic and important ecosystems that dampen impacts of coastal storms and are an integral part of tidal wetland systems, which sequester half of all global marine carbon. They are now being threatened due to sea-level rise, decreased sediment influx, and human encroachment. This book provides a comprehensive review of the latest salt marsh science, investigating their functions and how they are responding to stresses through formation of salt pannes and pools, headward erosion of tidal creeks, marsh-edge erosion, ice-fracturing, and ice-rafted sedimentation. Written by experts in marsh ecology, coastal geomorphology, wetland biology, estuarine hydrodynamics, and coastal sedimentation, it provides a multidisciplinary summary of recent advancements in our knowledge of salt marshes. The future of wetlands and potential deterioration of salt marshes is also considered, providing a go-to reference for graduate students and researchers studying these coastal systems, as well as marsh managers and restoration scientists.
The book thoroughly describes Iceland's geological development and its current geological processes, taking into account both geographic and geo-ecological aspects. Furthermore, it includes suggested excursions especially for individual tours. The most popular tourist "highlights" (e.g. the Golden Circle with thingvellir, Gullfoss and Geyser) should certainly not be excluded. But there is so much more to explore apart from the main tourist routes - and sometimes only a few kilometers away. Examining various regions of the country, each proposed stop is sufficiently described so that it is easily accessible (especially for individual tourists). A wealth of maps, graphics and images illustrate and supplement the coverage. This invaluable guide is aimed in particular at individual tourists to Iceland. It provides those tourists wishing to explore Iceland on their own with a wide range of suggestions for their trip. In addition, numerous excursion suggestions for the west, southwest and south, including the Westman Islands, are described in detail. |
