Consolidation Analyses of Soils (Hardcover): Jian-Hua Yin, Guofu Zhu Consolidation Analyses of Soils (Hardcover)
Jian-Hua Yin, Guofu Zhu
R3,540 Discovery Miles 35 400 Ships in 12 - 17 working days

When stresses are applied to saturated soil, deformation will occur as water in voids is squeezed out. Consolidation Analyses of Soils focuses on the consolidation of fully saturated soils. The book follows a classic approach by beginning with one-dimensional constitutive relations of soils and one-dimensional consolidation. It then moves on to analytical solutions to several one-dimensional consolidation problems and one-dimensional finite strain consolidation. The authors also present a finite element method for consolidation analysis of one-dimensional problems, analytical solutions to consolidation of soil with vertical drains, and a finite difference method for consolidation analysis of one-dimensional problems. Simplified methods for consolidation analysis of soils exhibiting creep are introduced and applied to different cases. Three-dimensional consolidation equations and solutions of typical three-dimensional consolidation problems are covered, as well as simplified finite element consolidation analysis of soils with vertical drain and finite element method for three-dimensional consolidation problems. The book is unique in that it covers both classic solutions and state-of-the-art work in consolidation analyses of soils. Authors Jian-Hua Yin is Chair Professor of Soil Mechanics in the Department of Civil and Environmental Engineering at The Hong Kong Polytechnic University. Guofu Zhu is a Professor in the Department of Engineering Structures and Mechanics at Wuhan University of Technology, China.

The main objective of this book is to integrate environmental knowledge observed in local agriculture, based on the understanding of soils science and ecology, and to propose possible technical solutions and a more integrated approach to tropical agriculture. The chapters describe and analyze the ecological and technical countermeasures available for mitigating environmental degradation due to the increasing agricultural activities by humans, based on our scientific understanding of traditional agriculture in the tropics. This is an effective approach, as such ecological and technical tools previously involved in traditional activities are expected to be easily incorporated into present agricultural systems. The book starts with a rather classical pedological issue and analyzed traditional agricultural practices with different resource management strategies in terms of their modification of natural biological processes. It focuses on the present situation of tropical agriculture; that is, resource utilization in modern agriculture after application of technical innovation (increased application of chemical fertilizers as well as agricultural chemicals). Here, possible technical approaches to resource management that reasonably support agricultural production whilst mitigating environmental degradation are discussed. The negative impacts of agricultural development on our environment are rapidly growing, yet we are increasingly dependent on the agricultural sector for food and energy. The situation is similar in the tropics, where subsistence agriculture with low input management has long comprised most agricultural systems. Comparison of ecological and/or agronomical studies between different continents are still rare; therefore, this analysis may help clarify what is an essential problem when considering technical transportation beyond continents and/or between temperate and tropical regions.

Paleomagnetism, Volume 73 - Continents and Oceans (Hardcover, 2nd edition): Michael W. McElhinny, Phillip L. McFadden Paleomagnetism, Volume 73 - Continents and Oceans (Hardcover, 2nd edition)
Michael W. McElhinny, Phillip L. McFadden; Series edited by Renata Dmowska, James R. Holton +, H. Thomas Rossby
R1,199 Discovery Miles 11 990 Ships in 12 - 17 working days

Paleomagnetism is the study of the fossil magnetism in rocks. It has been paramount in determining that the continents have drifted over the surface of the Earth throughout geological time. The fossil magnetism preserved in the ocean floor has demonstrated how continental drift takes place through the process of sea-floor spreading. The methods and techniques used in paleomagnetic studies of continental rocks and of the ocean floor are described and then applied to determining horizontal movements of the Earth's crust over geological time. An up-to-date review of global paleomagnetic data enables 1000 million
years of Earth history to be summarized in terms of the drift of the major crustal blocks over the surface of the Earth.
The first edition of McElhinny's book was heralded as a "classic and definitive text." It thoroughly discussed the theory of geomagnetism, the geologic
reversals of the Earth's magnetic field, and the shifting of magnetic poles. In the 25 years since the highly successful first edition of Palaeomagnetism and Plate Tectonics (Cambridge, 1973) the many advances in the concepts, methodology, and insights into paleomagnetism warrant this new treatment. This completely updated and revised edition of Paleomagnetism: Continents and Oceans will be a welcome resource for a broad audience of earth scientists as well as laypeople curious about magnetism, paleogeography, geology, and plate tectonics.
Because the book is intended for a wide audience of geologists, geophysicists, and oceanographers, it balances the mathematical and descriptive aspects of each topic.
* Details the theory and methodology of rock magnetism, with particular emphasis onintrepreting crustal movements from continental and oceanic measurements
* Outlines Earth history for the past 1000 million years, from the Rodinia super-continent through its breakup and the formation of Gondwana to the formation and breakup of Pangea and the amalgamation of Eurasia
* Provides a comprehensive treatment of oceanic paleomagnetism
* Provides a set of color pateogeographic maps covering the past 250 million years
* Written by two internationally recognized experts in the field

Clay minerals are one of the most important groups of minerals that destroy permeability in sandstones. However, they also react with drilling and completion fluids and induce fines migration during hydrocarbon production. They are a very complex family of minerals that are routinely intergrown with each other, contain a wide range of solid solutions and form by a variety of processes under a wide range temperatures and rock and fluid compositions.

In this volume, clay minerals in sandstones are reviewed in terms of their mineralogy and general occurrence, their stable and radiogenic isotope geochemistry, XRD quantification, their effects on the petrophysical properties of sandstones and their relationships to sequence stratigraphy and palaeoclimate. The controls on various clay minerals are addressed and a variety of geochemical issues, including the importance of mass flux, links to carbonate mineral diagenesis and linked clay mineral diagenesis in interbedded mudstone-sandstone are explored. A number of case studies are included for kaolin, illite and chlorite cements, and the occurrence of smectite in sandstone is reviewed. Experimental rate data for clay cements in sandstones are reviewed and there are two model-based case studies that address the rates of growth of kaolinite and illite.

The readership of this volume will include sedimentologists and petrographers who deal with the occurrence, spatial and temporal distribution patterns and importance of clay mineral cements in sandstones, geochemists involved in unraveling the factors that control clay mineral cement formation in sandstones and petroleum geoscientists involved in predicting clay mineral distribution in sandstones. The book will also be of interest to geologists involved in palaeoclimate studies basin analysis.Latest geochemical data on clays in sandstonesProvides important information for geologists involved in basin analysis, sandstone petrology and petroleum geology

Why an awareness of Earth's temporal rhythms is critical to our planetary survival Few of us have any conception of the enormous timescales of our planet's long history, and this narrow perspective underlies many of the environmental problems we are creating. The lifespan of Earth can seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth's history-and the magnitude of our effects on the planet. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future. Featuring illustrations by Haley Hagerman, this compelling book offers a new way of thinking about our place in time, showing how our everyday lives are shaped by processes that vastly predate us, and how our actions today will in turn have consequences that will outlast us by generations. This edition includes discussion questions for reading groups.

The report presents the results of the measurements of grain size, total organic carbon (TOC),hydrocarbons and metals in surface sediments (greater than 100 samples) collected from 40 locations off the coast of northern Mozambique during an environmental survey in March-April 2018. The survey was carried out from the R/V Dr Fridtjof Nansen in the following areas: (i) Pemba - planned gas industry logistic base, (ii) Ibo Island (Quirimbas National Protected Area) to St. Lazarus Bank - the reference area, and(iii) Palma - gas exploration area. The contents of fine-grained fraction (les than 63 um) of the sediment varied strongly in all areas from coarse sediment to high mud contents, whereas TOC levels were generally low and correlated poorly with fine-grained fraction. Background levels of hydrocarbons and metals were found in most of the samples. Anthropogenic contamination was found at one site in Pemba harbour. No oil-related contamination was demonstrated, including the Palma area where gas exploration is concentrated. Elevated concentrations of barium and total hydrocarbon content at some locations in the Palma area are attributed to drilling activities but are not considered to be of environmental concern. Based on the measured concentrations of chemicals, background concentrations for the studied areas are proposed

Southern California is sandwiched between two tectonic plates with an ever-shifting boundary. Over the last several million years, movements of these plates have dramatically reshuffled the Earth's crust to create rugged landscapes and seascapes riven with active faults. Movement along these faults triggers earthquakes and tsunamis, pushes up mountains, and lifts sections of coastline. Over geologic time, beaches come and go, coastal bluffs retreat, and the sea rises and falls. Nothing about Southern California's coast is stable. Surf, Sand, and Stone tells the scientific story of the Southern California coast: its mountains, islands, beaches, bluffs, surfing waves, earthquakes, and related phenomena. It takes readers from San Diego to Santa Barbara, revealing the evidence for how the coast's features came to be and how they are continually changing. With a compelling narrative and clear illustrations, Surf, Sand, and Stone outlines how the coast will be altered in the future and how we can best prepare for it.
