Treatise on Geophysics: Geomagnetism, Volume 5, provides an overview of the most important aspects of geomagnetism. The book begins by tracing the history of the study of geomagnetism. It then reviews global models of the Earth's magnetic field; the main sources of external magnetic field contributions; and the instruments and practices used to observe and measure the full range of features of the geomagnetic field. It discusses the origins of current knowledge of the secular variation of the Earth's magnetic field; crustal magnetism; geomagnetic excursions; the study of geophysical electromagnetic induction; the magnetization process; and the status of recent magnetic field data and their applications. The remaining chapters cover the geometry of the geomagnetic field and its temporal variability as recorded in volcanic and sedimentary rocks over the past few million years; the ocean crust as a recorder of geomagnetic field variations; and the theoretical basis for paleointensity experiments in igneous and sedimentary environments. The final chapter explains the concept of true polar wander (TPW), defined as shifts in the geographic location of Earth's daily rotation axis and/or by fluctuations in the spin rate (length of day anomalies).

The chapters in this book will cover the paleontology and geology of some important rock formations (Paleozoic and Paleogene) in the northeastern United States. The emphasis will be on brachiopod paleontology, specifically taxonomy, but will also include comments on morphologic variation and community analysis. The Martinsburg formation in the lower mid-Hudson Valley has been studied for many years but recently yielded numerous marine fossils that shed new light on the community ecology of the formation in the region. The Middle Silurian Shawangunk Formation near New Paltz, New York, is an important ridge-maker that extends toward the southwest into Pennsylvania. Recently discovered rare trace fossils in the Shawangunk will be discussed along with the depositional environment of the conglomerate. The Onondaga Limestone is a well-known formation that crops out from Port Jervis, northeast toward Albany and the westward to Buffalo. The brachiopods and community structure of the formation will be covered in some detail. The paleoecology of the Paleogene Hornerstown Formation of New Jersey will also be discussed, including a biostrome of large terebratulid brachiopods.

Geologists must be able to "read" a geological map. That means interpreting the vertical dimension through the 2D view represented on the map and at different scales. The main objective of this book is to help students during this difficult learning process. Based on an abundant iconography (field photos, maps, cross-sections) and on basics in mathematics and mechanics, the book dissects the geometry of emblematic geological structures and objects in order to build 3 D models, printable in 3D. The book is dedicated to structural geology with a particular emphasis on kinematics of faulting and folding and on salt tectonics (chapters III, IV and V). The origin of continental great unconformities and oceanic break-up unconformities is also discussed (chapter II). The audience of the book is broad and includes (under)graduate students in Earth Sciences, professors of Natural Sciences, and professional or amateur geologists.

This invaluable volume set of Advances in Geosciences continues the excellent tradition of the Asia-Oceania scientific community in providing the most up-to-date research results on a wide range of geosciences and environmental science. The information is vital to the understanding of the effects of climate change, extreme weathers on the most populated regions and fastest moving economies in the world. Besides, these volumes also highlight original papers from many prestigious research institutions which are conducting cutting edge studies in atmospheric physics, hydrological science and water resource, ocean science and coastal study, planetary exploration and solar system science, seismology, tsunamis, upper atmospheric physics and space science.

Conservation of monuments and historic sites is one of the most challenging problems facing modern civilization. It involves various cultural, humanistic, social, technical, economical and administrative factors, intertwining in inextricable patterns. The complexity of the topic is such that guidelines or recommendations for intervention techniques and design approaches are difficult to set. The Technical Committee on the Preservation of Monuments and Historic Sites (named TC19) was established by the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) in 1981, is supported by the Italian Geotechnical Society (AGI), and renamed TC301 in 2010. Geotechnics and Heritage, collects relevant case histories on the role of geotechnical engineering in the preservation of monuments and historic sites, and is an addition to the Proceedings of the two International Symposia organized by the Committee in Napoli in 1994 and 2013. The contributions in the book prove the significant role geotechnical engineering plays in conservation of historic building and monuments.

Celebrating Frits Agterberg's half-century of publication activity in geomathematics, this volume's 28 timely papers, written by his friends and colleagues, treat a variety of subjects of current interest, many of them also studied by Frits, including: spatial analysis in mineral resource assessment, quantitative stratigraphy, nonlinear multifractal models, compositional data analysis, time series analysis, image analysis, and geostatistics. Professor Agterberg published his first paper as a graduate student in 1958 and has since produced (and continues to publish) a steady stream of research papers on a wide variety of subjects of interest to geomathematical practitioners. Most of the papers included here address methodology and feature practical case studies, so that the book likely has broad appeal to those interested in mathematical geosciences, both to academic researchers seeking a comprehensive overview and also to practitioners of geomathematical approaches in industry.

Join the conversation as an earth scientist and a Native American elder-wise men from two cultures-explore the natural history of the Lake Superior region, examining both the science and the spirit of the land. As the geologist carefully presents a modern scientific perspective, the storyteller eloquently recounts a traditional Native American understanding, passed on through tales, myths, and symbols that illustrate how intimately his people have known and honored the earth and its history for over a hundred centuries. Talking Rocks is not only a story of geological history told from two perspectives, it is also a chronicle of two people from very different cultural and scientific heritages learning to understand and appreciate each other's distinct yet complementary ways of viewing the land we share.

This book focuses on the river morphodynamics and stream ecology of the Qinghai-Tibet Plateau. The objective of the book is to summarize and synthesize the recent studies based on field surveys undertaken in the period 2007-2014. This book was written to serve as a graduate-level text for a course in river dynamics and stream ecology and as a reference text for engineers and researchers engaged in hydropower engineering, fluvial geomorphology and aquatic ecology. The first two chapters serve as an introduction of geomorphological characteristics as well as uplift and its impact on river morphology of the Qinghai-Tibet Plateau. Chapters 3-5 cover meandering rivers and cutoff, wetlands and wetland shrinkage,desertification and restoration strategies in the Sanjiangyuan region. Chapter 6 discusses the interaction between erosion and vegetation, and Chapter 7 characterizes the aquatic ecology of the Yarlung Tsangpo and the Sanjiangyuan region.

During the Neogene - covering the last 23 Million years - the evolution of the environmental setting in Africa was subject to considerable changes. Natural shifts, slow and rapid, evidenced by modifications in palaeogeography, geodynamics, climate, and vegetation have caused repeated and strong changes of ecosystems in the lower latitudes. Using a variety of proxy data - researched and applied by many authors from numerous disciplines - an attempt is made to reconstruct African landscapes over space and time. Besides such spatio-temporal oscillations in recently humid, semi-humid, and dry areas of Africa, this volume of Palaeoecology of Africa (PoA) focuses on long term interrelationships between ecosystem dynamics and climate change, not ignoring the ever growing and ongoing influence of humans on natural ecosystems since the Quaternary. Regionally, this volume lays a strong focus on Nigeria (Niger Delta). Facing the omnipresent challenges of Global Change, an increasing number of African scientists is involved in palaeoenvironmental and palaeoclimatic research, both theoretical and applied. PoA systematically supports established as well as junior African scientists in the field of sustainable cooperation and academic capacity building. This book will be of interest to all concerned with or interested in up-to-date research on Neogene to Quaternary low latitudes ecosystem changes and their respective interpretation in the framework of natural climate and vegetation change evidenced by a variety of methods that allow to read and learn from the past by following the motto, "The geologic foretime as the key to the present, and possibly to the future." Palynologists, Geologists, Geographers, Archaeologists, and Geomorphologists will find this edition equally useful for their work.

This book presents a unique and up-to-date summary of what is known about groundwater on our planet, from a global perspective and in terms of area-specific factual information. Unlike most textbooks on groundwater, it does not deal with theoretical principles, but rather with the overall picture that emerges as a result of countless observations, studies and other activities related to groundwater in all parts of the world. The focus is on showing the role and geographical diversity of groundwater-a natural resource of great importance in daily life, but poorly understood by the general public and even by many water sector professionals. The book starts by analysing groundwater in the context of the hydrological cycle. Subsequently, groundwater systems as physical units, with their boundaries mainly defined by geological conditions, are reviewed. The next chapter looks at groundwater as a resource, paying attention, among others, to its quantity and quality, to the differentiation between renewable and non-renewable resources, and to the techniques for withdrawing groundwater. This is followed by a systematic documentation of the quantities of groundwater withdrawn and used around the world, and of the corresponding shares of groundwater in each of the main water use sectors. After that, steadily growing needs for groundwater management interventions are identified, resulting from local human activities and global change (including demography, economic development and climate change). Finally, groundwater resources management is addressed and real-life cases are described that illustrate actions taken and experiences with different issues in different parts of the world. The authors attempted to write this book in such a way that it is accessible to a wider readership than just groundwater professionals. It will also benefit non-groundwater specialists who work in groundwater-related fields (water managers, land use planners, environmentalists, agronomists, engineers, economists, lawyers, and journalists), by broadening their understanding of groundwater and making them aware of the huge variety of groundwater settings. Groundwater specialists will use the book as a convenient reference on the geographical diversity of groundwater. Part of the contents or interpretations offered may even be new to them or enhance their knowledge of some aspects. The many maps, tables, and references will save much time for those who would otherwise have to search elsewhere for basic information on the globe's groundwater.

West Africa and the eastern Atlantic stretching from Mauritania in the north to Namibia in the south offer a large latitudinal stretch incorporating nearly symmetrical climatic gradients from the Equator. On the time scale of Quaternary Glacial and Interglacial cycles, today, we possess well-documented and recently published marine sedimentary records showing changes in oceanic and atmospheric circulations and terrestrial fluxes. Deep-sea sediment records contain a wide range of palaeoenvironmental indicators like oxygen and carbon isotopes, alkenones, foraminiferal and other planktonic assemblages over time periods up to and greater than 125,000 years. These are signals of temperature and circulation shifts and allow Interglacial and Glacial comparisons on a regional and inter-hemispheric scale. However, this effort to synthesize the existing knowledge cannot yet aspire to a global modelling. Linking with terrestrial records, albeit spatially patchy and generally lacking a firm chronology, this book points to shorter time scale chronologies from lakes, marshes and river deposits. Diverse and not very wellknown literature, both French and English, is reported here. Lastly, the book records recent knowledge of the first steps of human occupation of frequently hostile environments and considers the environmental impact of ancient and modern societies.
* Covers the recent studies about marine Quaternary environments off West Africa, as well as continental Quaternary environments of tropical and sub-tropical West Africa (over 10,000 to 100,000 years)
* Compares the parallel between palae-oenvironmental trends according to latitudinal gradients

Fractured rocks extend over much of the world, cropping out in shields, massifs, and the cores of major mountain ranges. They also form the basement below younger sedimentary rocks; at depth; they represent a continuous environment of extended and deep regional groundwater flow. Understanding of groundwater flow and solute transport in fractured rocks is vital for analysis of water resources, water quality and environmental protection, geotechnical and engineering projects, and geothermal energy production. Book chapters include theoretical and practical analyses using numerical modelling, geochemistry, isotopes, aquifer tests, laboratory tests, field mapping, geophysics, geological analyses, and some unique combinations of these types of investigation. Current water resource and geotechnical problems in many countries-and the techniques now used to address them-are also discussed. The importance of geological interpretation is re-emphasised in analysing the hydrogeology of fractured, mostly crystalline rocks and in how critical this is for understanding their hydrology and the wise utilisation of resources. This is indeed hydrogeology in its broadest sense. The importance of, but great difficulty in, extending or upscaling fractured rock hydraulic properties is also made clear. This book is aimed at practicing hydrogeologists, engineers, ecologists, resource managers, and perhaps most importantly, students and earth scientists not yet familiar with the ubiquity and importance of fractured rock systems.

This is the first book to appear which correlates within a single volume the relevant data for both archeological and geological dating of human fossil remains. The author was trained both as a geologist and as a prehistorian, and has written this book first to meet the needs of archeologists wishing to learn the stratigraphical frameworks now applied to Quaternary deposits, and second to meet the needs of geologists requiring to know the terminology of Paleolithic and Mesolithic cultures.

In this book the author makes use of the results obtained from the latest dating techniques, both relative and absolute. Charts give the latest radiocarbon datings of Middle and Upper Paleolithic sites and cultures in Europe, the Near East and Africa. In an appendix all the most important human fossil remains are listed by name, with dates of discovery, stratigraphical and cultural datings, and absolute ages where known.

When this book was first released "Science" magazine called it "A most significant milestone for the study of early man . . . brings together for the first time the results obtained from the relative and absolute dating techniques in use today . . . The book presents this evidence with a clarity that makes it indispensable to all concerned with the research and teaching of paleoanthropology." While the "American Anthropologist" commented "Kenneth Oakley's book is a splendid and unique contribution to the temporal aspect of paleoanthropological studies."

"Kenneth Oakley" (1911-1981) was best known for his work in relative dating with fossils. He graduated from University College in Geology and Anthropology, and worked for the British Museum. He had an international reputation in his field and was particularly well known for his part in exposing the Piltdown fraud. His publications include "Man the Tool-Maker," and over 100 papers, many of them on analytical methods of dating bones, particularly the fluorine-dating method.

This book, first published in 1981, provides an excellent introductory analysis to plate tectonic theory. It covers plate tectonics, continental drift, mountain building, ocean trenches, earthquakes and volcanoes.

This book, first published in 1986, is an excellent introduction to the main topics of economic and applied geology for undergraduate students of geology, geophysics, mining geology and civil engineering.

This practical guidebook provides a basic grounding in the principles of geology and explains how to apply them. Using this book, readers will be able to figure out whether they are standing on an ancient seafloor, coal swamp, or sand dune. They will be able to determine the geologic hazards in their neighborhood, where to look for fossils and minerals, or where best to drill a water well. In plain English, The Geology Companion sheds light on the processes that shape the earth and how geology affects people in their daily lives.

Properly understanding and characterizing geologic materials and formations is vital for making critical engineering decisions. Identifying and classifying rock masses and soil formations allows reasonable estimation of their characteristic properties. Comprising chapters from the second edition of the revered Geotechnical Engineering Investigation Handbook, Characteristics of Geologic Materials and Formations provides a basis for recognizing, identifying, and classifying the various rock and soil types. With clear, concise, and hands-on guidance, this book describes these rock and soil types in terms of their origin, mode of occurrence, and structural features in situ and presents the typical characteristics that are of engineering significance. It also explains the elements that affect surface and subsurface water engineering in terms of controlling floods, erosion, subsurface flow, and seepage, as well as for water conservation. Supplying important correlations used to estimate engineering and geologic properties, the book presents correlations for intact rock, rock masses, and soil formations throughout the chapters and condenses this information into a convenient summary table in an appendix. Eliminate the need to search through narrow volumes or large handbooks with Characteristics of Geologic Materials and Formations: A Field Guide for Geotechnical Engineers, a convenient and complete guide to the techniques you need.
