North-East India, comprising the seven contiguous states around Assam, the principal state of the region, is a relatively unknown, yet very fascinating region. The forest clad peripheral mountains, home to indigenous peoples like the Nagas, Mizos and the Khasis, the densely populated Brahmaputra valley with its lush green tea gardens and the golden rice fields, the moderately populated hill regions and plateaus, and the sparsely inhabited Himalayas, form a unique mosaic of natural and cultural landscapes and human interactions, with unparalleled diversity. The book provides a glimpse into the region's past and gives a comprehensive picture of its physical environment, people, resources and its economy. The physical environment takes into account not only the structural base of the region, its physical characteristics and natural vegetation but also offers an impression of the region's biodiversity and the measures undertaken to preserve it. The people of the region, especially the indigenous population, inhabiting contrasting environments and speaking a variety of regional and local dialects, have received special attention, bringing into focus the role of migration that has influenced the traditional societies, for centuries. The book acquaints the readers with spatial distribution, life style and culture of the indigenous people, outlining the unique features of each tribe. The economy of the region, depending originally on primitive farming and cottage industries, like silkworm rearing, but now greatly transformed with the emergence of modern industries, power resources and expanding trade, is reviewed based on authentic data and actual field observations. The epilogue, the last chapter in the book, summarizes the authors' perception of the region and its future.

Originally published in 1984. This major text covers the whole discipline of geomorphology, presenting a clear and comprehensive overview of the field, drawing on the full range of modern research. Landforms and their formative processes are treated on a broad spectrum of spatial scales, and examples are drawn from the major geological, climatic and biotic environments. The book is divided conveniently into some 170 clearly defined sections to allow readers to make the most efficient use of those parts of the text relevant to their particular needs. After introducing the basic concepts such as systems analysis, morphologic and cascading systems, the historical-evolutionary approach and process-response geomorphology, the book moves on to the geological background to geomorphology and then the extensive third part deals with the geomorphic processes and responding landforms. Part four examines climatic geomorphology and the appendix touches on applied geomorphology, especially fluvial processes.

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)

This book provides a general survey of Geocryology, which is the study of frozen ground called permafrost. Frozen ground is the product of cold climates as well as a variety of environmental factors. Its major characteristic is the accumulation of large quantities of ice which may exceed 90% by volume. Soil water changing to ice results in ground heaving, while thawing of this ice produces ground subsidence often accompanied by soil flowage. Permafrost is very susceptible to changes in weather and climate as well as to changes in the microenvironment. Cold weather produces contraction of the ground, resulting in cracking of the soil as well as breakup of concrete, rock, etc. Thus permafrost regions have unique landforms and processes not found in warmer lands. The book is divided into three parts. Part 1 provides an introduction to the characteristics of permafrost. Four chapters deal with its definition and characteristics, the unique processes operating there, the factors affecting it, and its general distribution. Part 2 consists of seven chapters describing the characteristic landforms unique to these areas and the processes involved in their formation. Part 3 discusses the special problems encountered by engineers in construction projects including settlements, roads and railways, the oil and gas industry, mining, and the agricultural and forest industries. The three authors represent three countries and three language groups, and together have over 120 years of experience of working in permafrost areas throughout the world. The book contains over 300 illustrations and photographs, and includes an extensive bibliography in order to introduce the interested reader to the large current literature.

In this re-evaluation of the basic postulates of geomorphology, first published in 1982, Alistair Pitty examines the subject within its scientific context, arguing that coherence in geomorphology can be demonstrated despite the many apparent divergences, which should themselves be regarded as poles within a spectrum of opinion. Not least, the particularly geological and geographical aspects of geomorphology are carefully identified and explained within this coherence.

This book, first published in 1982, is a collection of articles aimed at advancing the field of geomorphology. It starts from the position that a meaningful grasp of landscape evolution would depend upon an understanding of the present spatial distribution of processes and process rates; comparison of spatial versus temporal change; and careful appraisal of the character and composition of the stratigraphic record. Each article uses a data set to address between threshold variability in either a spatial or temporal context, and often both.

This book, first published in 1980, collects together thirteen articles on 'Geomorphology in Arid Regions'. It uses the term 'arid' loosely to include studies from climes which might otherwise be considered semi-arid, in order to provide a diversity of papers dealing with important problems of interest to geomorphologists today.

This book, first published in 1985, is a comprehensive guide to the main ideas in the history of geomorphology. It traces the development of thinking on landforms, with material ranging from the ancient world to the present day. The main areas covered are the Renaissance, the explosive growth of the Natural Sciences in the nineteenth century and the impact of the Second World War. The papers and theories of specialists like James Hutton, John Playfair and W.M. Davies are presented and discussed and the final chapters reflect on future change, based on the past and speculation on possible developments. Balance is maintained between the dual importance and dominance of English and North American contributions to the subject, and quite substantial research was undertaken to provide a more complete approach to some areas hitherto neglected.

Soils and sediments influence current processes, preserve evidence of past processes, indicate evolutionary phases in landscapes and provide a basis for relative and absolute chronologies. They provide an important key to the integration of short-term process studies and investigation of longer-term landform evolution. This book, first published in 1985, has been arranged to provide wide temporal and spatial coverage, with studies ranging from historic to geologic time scales and micro- to macro-spatial scales. The interdisciplinary nature of the subject is reflected in contributions from soil scientists, engineering geologists, hydrologists and geomorphologists.

The tropics provide the key to understanding much biological and Earth science. This is particularly true for the study of landforms, which in higher latitudes suffer great seasonal contrasts in process intensity and type, and which often in the past underwent the dramatic changes of glaciation and periglaciation. Yet studies in the tropics have shown that the legacy of past climate changes is much more dramatic than was formerly believed. This book, first published in 1985, brings together the variety of evidence about such environmental changes, over a variety of timescales, and sets it against the current knowledge of the nature of geomorphic processes in the tropics.

This book, first published in 1986, stems from the 1986 Binghamton Geomorphology Symposium. The topic was chosen because of the advances in the study of aeolian processes and landforms, particularly in the area of desertification, and the papers collected here clearly indicate that their study is not constrained by discipline boundaries but are of interest to geologists, physical geographers, soil scientists, meteorologists and engineers.

This book, first published in 1973, focuses on non-urban terrain, and presents a uniquely balanced historical treatment of both the land degradation induced by man and his efforts at conservation, preservation and reclamation.

This book, first published in 1979, collects together a key set of papers from the 10th Binghamton Geomorphology Symposium. They analyse fluvial theory, channel processes, stream adjustments, paleo-adjustments and channel adjustments.

This book, first published in 1980, is a timely and comprehensive appraisal of thresholds in geomorphology. The papers, arising from the 9th Binghamton Geomorphology Symposium, form the cornerstone of a subject that is increasingly important in geomorphology. This book analyses the historical background to thresholds and geomorphology, as well as fluvial landforms, hydrogeologic regimes and other processes, and the impact of man.

Whether the project is river engineering, soil mapping for landuse planning, or control of landslides, this volume, first published in 1976, illustrates that the professional partnership between geomorphology and engineering can significantly minimize environmental damage. The papers here were presented at the 7th Binghamton Geomorphology Symposium, and using the broad viewpoint of the planner, much new ground is covered: landfill design, prediction of geomorphic processes and their effects, and minimization of streamflow distortion.

This book, first published in 1989, the proceedings of the 19th Binghamton Geomorphology Symposium, is the first set of essays focused on the history of the subject. The articles analyse the founding precepts of geomorphology, the early pioneers, the formation of a defined discipline, and the present state of the topic.

This book, first published in 1973, presents the papers from the 3rd Binghamton Geomorphology Symposium. The necessity for interdisciplinary cooperation in research on the processes and terrain of the littoral zone is reflected here, and the central theme that emerges from all papers is the dynamic aspect of the coastal environment, and the way geomorphic principles can be used to solve problems.

This unique treatment of geomorphology, first published in 1986, provides a comprehensive work to enable students to see the subject as a whole. Taking the concepts that run through the subject and cut across its standard divisions, the book summarises the history of intellectual debate in geomorphology and then describes modern developments, both pure and applied.

Time is a central feature of geomorphological research, and is used in this book (first published in 1977) to provide a conceptual framework within which to consider and compare old and new approaches to the field of geomorphology. The emphasis is on providing not merely a manual of current research but an introduction to isolate ideas and concepts, stimulate critical discussion and examine some of the problems that are involved in dealing with data.

Glaciotectonism is an important component of modern glacial theory, gaining widespread recognition within the past 25 years. This book is outcome of compiling maps of glaciotectonic structures and landforms for North America and central Europe, which is the basis for better understanding the role of glaciotectonism as a key component of glacial theory.
Glaciotectonism is intented to provide a comprehensive review and description of glaciotectonic phenomena. The subject matter is arranged in three broad sections. First, definitions, principles, and methodologies of glaciotectonics in the field as well as in the laboratory are described. Next, case histories of glaciotectonic structures and landforms from the land and continental shelf regions of North America and Eurasia are then covered in detail. Practical applications for mining, highway construction, and other human activities are also described. The last part of the book covers regional and continental distribution of glaciotectonic phenomena, dynamics of glaciotectonic deformation, and analogous non-glacial deformation.
* Provides definitions, principles, and methodology of investigation for glaciotectonic phenomena
* Features case histories of glaciotectonic structures and landforms from the glaciated land and continental shelf regions of North America and Eurasia
* Analyzes mechanical and theoretical glaciotectonic deformation; analogous deformation of non-glacial origin

Soil Degradation in the United States: Extent, Severity, and Trends examines the magnitude and severity of soil degradation by different processes in the U.S., including water erosion, wind erosion, C depletion, soil compaction, salt build-up, and soil contamination. In addition, it addresses policy issues with regard to economic and environmental impact, land use change, and global trends. It covers past trends and future projections regarding soil degradation. The book provides a ready reference and data source for soil scientists and researchers, agronomists, environmentalists, land use planners, land managers, and policy makers.

This book is a practical guide to downhole rock sampling and coring concepts, methods, systems, and procedures for practitioners and researchers. Its chapters are based upon years of extensive studies and research about the coring methods and via direct and continuous communication and consultation obtained from various service and operator companies such as Baker Hughes GE, NOV, OMV, and Sandvik. The contributors discuss the state-of-the-art coring methods and systems (mainly used in the petroleum industry), which include: * conventional coring; * wireline continuous coring; * invasion mitigation coring (low invasion, gel coring, sponge coring); * jam-detection, anti-jamming, full closure; * safe-coring and tripping; * oriented-coring; * pressure/in-situ coring; * logging-while-coring; * motor coring; * mini-coring; * coiled Tubing Coring; and * underbalanced coring. The contributors provide practical and applicable understanding of the procedures of these coring methods and systems, as well as the specific core barrel components, working mechanisms, and schematics of the tools and processes used. Because Coring Methods and Systems analyses and compares the core barrels used in both petroleum and mining industries, it enhances the communication and may allow knowledge transfer between the two industries. As core damage is a serious issue during coring and handling jeopardizing correct calibration of exploration data, Coring Methods and Systems has greatly focused on its identification and its mitigation. Therefore, it can be used as an ideal source for geologists, core analysts, and reservoir engineers, to ensure the retrieval of high-quality cores.

This book provides insights into the benefits of using remote sensing data from a geoscientist's perspective, by integrating the data with the understanding of Earth's surface and subsurface. In 3 sections, the book takes a detailed look at what data explorationists use when they explore for hydrocarbon resources, assess different terrain types for planning and hazards and extract present-day geologic analogs for subsurface geologic settings. The book presents the usage of remote sensing data in exploration in a structured way by detecting individual geologic features as building blocks for complex geologic systems. This concept enables readers to build their own workflows for the assessment of complex geologic systems using various combinations of remote sensing data. Section 1 introduces readers to the foundations of remote sensing for exploration, covers various methods of image processing and studies different digital elevation and bathymetry models. Section 2 presents the concept of geomorphology as a means to integrate surface and subsurface data. Different aspects of rendering in 2D and 3D are explained and used for the interpretation and extraction of geologic features that are used in exploration. Section 3 addresses remote sensing for hydrocarbon exploration in detail, from geophysical data acquisition to development and infrastructure planning. The organization of this chapter follows an exploration workflow from regional to local modeling studying basin and petroleum system modeling as well as logistics planning of seismic surveys and near-surface modeling. Aspects of field development and infrastructure planning comprise multi-temporal and dynamic modeling. The section closes with a structured approach to extracting geologic analogs from interpreted remote sensing data. The book will be of interest to professionals and students working in exploration for hydrocarbons and water resources, as well as geoscientists and engineers using remote sensing for infrastructure planning, hazard assessment and dynamic environmental studies.

It is not possible to understand the present or future climate unless scientists can account for the enormous and rapid cycles of glaciation that have taken place over the last million years, and which are expected to continue into the future. A great deal has happened in the theory of the ice ages over the last decade, and it is now widley accepted that ice ages are driven by changes in the Earth's orbit. The study of ice ages is very inter-disciplinary, covering geology, physics, glaciology, oceanography, atmospheric science, planetary orbit calculations astrophysics and statistics.
