Book Synopsis Fluids In The Earth's Crust by : W.S. Fyfe
Download or read book Fluids In The Earth's Crust written by W.S. Fyfe and published by Elsevier. This book was released on 2012-12-02 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluids in the Earth’s Crust explores the generation and migration of fluids in the crust and their influence on the structure. This book also deals with the collection and concentration of these fluids into commercially possible reservoirs or their fossil trace formed as ore bodies. Chapter one of this book discusses fluid motion and geochemical and tectonic processes. It then defines fluid, discusses the rocks in the surface environment, and provides evidence of the changes of a rock’s position and the motion of fluids. This book also explores the chemistry of natural fluids, including the composition of ocean water; pore water and deep-drill fluids; metamorphic fluids; fluid inclusions; and magmatic fluids. Volatile species in minerals, such as water, carbon and carbon dioxide, chlorine, fluorine, sulfur, oxygen, and nitrogen and other inert gases, are presented in this book. Other chapters in this book cover the solubility of minerals and physical chemistry of their solutions; the metamorphic reactions and processes; buffer systems; rock deformation; crustal conditions; dewatering of crust; and diapirism. The last part of the book discusses fluids, tectonics, and chemical transport. This book will be of great value to mining and oil geologists, as well as to pure geologists.
Book Synopsis Fluid-Fluid Interactions by : Axel Liebscher
Download or read book Fluid-Fluid Interactions written by Axel Liebscher and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-12-17 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 65 of Reviews in Mineralogy and Geochemistry attempts to fill this gap and to explicitly focus on the role that co-existing fluids play in the diverse geologic environments. It brings together the previously somewhat detached literature on fluid–fluid interactions in continental, volcanic, submarine and subduction zone environments. It emphasizes that fluid mixing and unmixing are widespread processes that may occur in all geologic environments of the entire crust and upper mantle. Despite different P-T conditions, the fundamental processes are analogous in the different settings.
Book Synopsis The Role of Fluids in Crustal Processes by : National Research Council
Download or read book The Role of Fluids in Crustal Processes written by National Research Council and published by National Academies Press. This book was released on 1990-01-01 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water and other fluids play a vital role in the processes that shape the earth's crust, possibly even influencing earthquakes and volcanism. Fluids affect the movement of chemicals and heat in the crust, and they are the major factor in the formation of hydrothermal ore deposits. Yet, fluids have been overlooked in many geologic investigations. The Role of Fluids in Crustal Processes addresses this lack of attention with a survey of what experts know about the role of fluids in the Earth's crustâ€"and what future research can reveal. The overview discusses factors that affect fluid movement and the coupled equations that represent energy and mass transport processes, chemical reactions, and the relation of fluids to stress distribution.

Book Synopsis Fluid Movements — Element Transport and the Composition of the Deep Crust by : David Bridgwater
Download or read book Fluid Movements — Element Transport and the Composition of the Deep Crust written by David Bridgwater and published by Springer. This book was released on 2011-09-26 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many geologists have an equivocal attitude to fluid movements within the crust and the associated changes in the chemical and physical properties of crustal rocks. The controversies earlier this centuary between the "soaks" and the "pontiffs" memorably summarised by H. H. Read (1957) in The Granite Controversy have largely been resolved. Few would now advocate the formation of large granitic bodies by in situ transformation of pre-existing crust as the result of the passage of ichors without the formation of a granitic melt. To many geochemists fluid transport and metasomatism have become slightly suspect processes which at the most locally disturb the primary geochemical and isotopic signatures. While there is common agreement that there are marked differences in the composition of the lower and upper crust, the role of fluid movement as one of the controls of this differentiation is often neglected in favour of suggested primary differences in the composition of igneous rocks emplaced at different depths. Selective fluid transport however provides many geologists with their livelyhood. Without the secondary concentration of commercially important elements by fluids within the crust the mining industry, geological science and human activities based on their products would be very different.
Book Synopsis Geochemistry of Multiphase CO2-H20 Rock Interactions in Nanoconfined Environments by : Quin R. S. Miller
Download or read book Geochemistry of Multiphase CO2-H20 Rock Interactions in Nanoconfined Environments written by Quin R. S. Miller and published by . This book was released on 2017 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation is composed of five manuscript chapters that broadly concern the geochemistry of multiphase CO2-H2O interactions with rocks. Specifically, they focus on how organic ligands and nanoconfinement influence fluid-rock reaction processes and rates. It is important to understand these processes as CO2 and H2O are the two most abundant volatiles in the crust and strongly influence subsurface hydration and carbonation reactions. These processes have implications for natural and engineered settings, including geothermal systems, metamorphic aureoles, and carbon utilization and storage. These geochemical processes have the potential to alter hydrologic and geomechanical properties. In this dissertation, the reactivity of CO2-acidified brine and water-bearing supercritical CO2 with rocks was examined. Naturally-occurring organic ligands also play a role in CO2-H2O-rock interactions, as they have the potential to affect reaction rates and pathways. Lastly, properties of nanoconfined fluids differ from those of bulk fluids, which has implications for the reactivity of fluids in interpore chemical environments. Nanoconfined fluids are also important to understand because they are likely present at all mineral-water interfaces. The interaction of water with minerals surfaces induces ordering and the development of a nanoscale water phase. Chapters 2 through 4 concern the reaction of forsterite with water-bearing (wet) supercritical CO2 (scCO2). The carbonation reactions take place in an ~2 nm-thick interfacial water film that forms when water from the scCO2 partitions onto the forsterite. Chapter 2 focuses on how naturally-occurring organic ligands may be mobilized and transported by wet scCO2 to mineral interfaces, where they influence carbonation pathways. Chapters 3 and 4 continue this line of inquiry and delve into the underlying mechanism of how organic ligands influence mineral carbonation in interfacial water films. Chapter 5 focuses on how the water film thickness, or degree of nanoconfinement, influences forsterite carbonation rates, pathways, and energy barriers. This chapter places wet scCO2 investigations in a new context where they can provide insight into reactions in other confined environments, including pores, fractures, and grain boundaries. Chapter 6 concerns the aqueous geochemistry of the reaction of shale and CO2-acidified brine. In the context of the dissertation, shale is a naturally occurring, economically important, nanoporous, and organic-rich substrate. This chapter indicates that aqueous geochemistry correlates with fluid-rock reaction-induced pore network architecture reorganization. It has set the stage for ongoing and future work that will provide insight into coupled physicochemical processes.

Book Synopsis The Insect Viruses by : Lois K. Miller
Download or read book The Insect Viruses written by Lois K. Miller and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are over a million different species of insects, and individually they 8 outnumber humans by more than 10 to 1. Moreover, some insects live in close association with both plants and higher animals and naturally exchange viruses with them. It has even been speculated that viruses in general may have radiated through the plant and animal kingdoms from common insect origins. Be that as it may, since insects play pivotal roles in the biosphere, both to the benefit and detriment of mankind, they and the viruses that infect them are important subjects for study. Insects are infected by a diverse medley of viruses, and this volume focuses on those insect virus families that are found primarily or exclusively in insects. All major families of insect-selective viruses are covered except for the baculo viruses, which were described in a separate volume of The Viruses series. Included in this volume are the established families of insect viruses, the newly recognized ascovirus family, and the nudiviruses, which probably represent a separate family but currently remain unclassified. The coverage of arboviruses is limited to a single chapter that focuses on their potential utility as vectors and in insect control. Omitted for practical reasons are several individual insect viruses that have been described sporadically in the literature and probably represent novel virus families.
Book Synopsis Seismic Ground Motion In Large Urban Areas by : Giuliano F. Panza
Download or read book Seismic Ground Motion In Large Urban Areas written by Giuliano F. Panza and published by Springer Science & Business Media. This book was released on 2004-04-23 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accelerated, and often uncontrolled, growth of the cities has contributed to the ecological transformation of their immediate surroundings. Factors contributing to the urban vulnerability include: lowering or rising of the water table, subsidence, loss of bearing capacity of soil foundations and instability of slopes. Recent catastrophic earthquakes highlight the poor understanding by decision makers of seismic related risk, as well as the tendency of some builders to use the cheapest designs and construction materials to increase short-term economic returns on their investment. Losses from earthquakes will continue to increase if we do not shift towards proactive solution. Disaster reduction is both an issue for consideration in the sustainable development agenda and a cross-cutting issue relating to the social, economic, environmental and humanitarian sectors. As location is the key factor, which determines the level of risk associated with a hazard, land-use plans and mapping should be used as tools to identify the most suitable usage for vulnerable areas.

Book Synopsis Quaternary Vegetation Dynamics by : Jürgen Runge
Download or read book Quaternary Vegetation Dynamics written by Jürgen Runge and published by CRC Press. This book was released on 2021-11-28 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book celebrates the relaunch of the African Pollen Database, presents state-of-the-art of modern and ancient pollen data from sub-Saharan Africa, and promotes Open Access science. Pollen grains are powerful tools for the study of past vegetation dynamics because they preserve well within sedimentary deposits and have a huge diversity in ornamentation that allows different taxa to be determined. The reconstruction of past vegetation from the examination of ancient pollen records thus can be used to characterize the nature of past landscapes (e.g. abundance of forests vs. grasslands), provide insights into changes in biodiversity, and gain empirical evidence of vegetation response to climatic change and human activity. In this, the 35th Volume of "Palaeoecology of Africa", we bring together new data and extensive synthetic reviews to provide novel insights into the relationships between human evolution, human activity, climate change and vegetation dynamics during the Quaternary, the last 2.6 million years. Current and ongoing climate and land-use change is exerting pressure on modern vegetation formations and threatening the livelihoods and wellbeing of many peoples in Africa. In this book the focus is on the Quaternary because it is during this geological period that the modern vegetation formations developed into their current configurations against a backdrop of high magnitude global climate change (glacial-interglacial cycles), human evolution, and a growing human land-use footprint. In this book the latest information is presented and collated from around the African continent to parameterize past vegetation states, identify the drivers of vegetation change, and assess the vegetation resilience to change. To achieve this research from two broad themes are covered: (i) the present is the key to the past (i.e. studies which improve our understanding of modern environments so that we can better interpret evidence from the past), and (ii) the past is the key to the future (i.e. studies which unlock information on how and why vegetation changed in the past so one can better anticipate trajectories of future change). This Open Access book will provide a strong foundation for future research exploring past ecological, environmental and climatic change within Africa and the surrounding islands. The book is organized regionally (covering western, eastern, central, and southern Africa) and it contains specialized articles focused on particular topics (such as modern pollen-vegetation relationships and fire as a driver of vegetation change), as well as regional and pan-African syntheses drawing together decades of research to assess key scientific questions (including the role of climate in driving vegetation change and the role of vegetation change in human evolution). These articles will be useful to students and teachers from high school to the highest level of university who are interested in the origins and dynamics of vegetation in Africa. Furthermore, it is also meant to provide societally relevant information that can act as an inspiration for the development of sustainable management practices for the future.
