Mineral deposits have supplied useful or valuable material for human consumption long before they became objects of scientific curiosity or commercial exploitation. In fact, the earliest human interest in rocks was probably because of the easily accessible, useful (e. g. , red pigment in the form of earthy hematite) or valuable (e. g. , native gold and gemstones) materials they contained at places. In modem times, the study of mineral deposits has evolved into an applied science employing detailed field observations, sophisticated laboratory techniques for additional information, and computer modeling to build complex hypotheses. Understanding concepts that would someday help geologists to find new mineral deposits or exploit the known ones more efficiently have always been, and will continue to be, at the core of any course on mineral deposits, but it is a fascinating subject in its own right, even for students who do not intend to be professional economic geologists. I believe that a course on mineral deposits should be designed as a "capstone course" that illustrates a comprehensive application of concepts from many other disciplines in geology (mineralogy, stratigraphy and sedimentation, structure and tectonics, petrology, geochemistry, paleontology, geomorphology, etc. ). This book is intended as a text for such an introductory course in economic geology, primarily for senior undergraduate and graduate students in colleges and universities. It should also serve as a useful information resource for professional economic geologists.
Oceanic basalts are the most abundant rock type found at the earth's surface, and as such they have been the subject of considerable research, particularly since the concept of sea-floor spreading became widely accepted. This book provides a review of these rocks, first dicussing how we sample the ocean floor and what we know about the structure of the oceanic crust, followed by an overview of the various regional settings (Pacific crust, Atlantic crust, marginal basins, seamounts and islands) and finally examines the main processes (and their interactions) which prevail during the generation and emplacement of oceanic basalt magmas. This is a volume for geologists, geochemists and geophysicists and a source of reference for advanced undergraduate students and postgraduates in these disciplines.
This volume arises from the NATO Advanced Research Workshop (ARW) on 'North African Cretaceous rudist and coral formations and their contributions to carbonate platform development , which was held in Tunisia, on 13-18 May, 2002. It was convened by M. El Hedi Negra (Universite 7 Novembre de Carthage, now Universite de Tunis El Manar, Tunisia) and Eulalia Gili (Universitat Autonoma de Barcelona, Spain). The aims of the ARW were: (1) to review and critically assess currently available data on rudist/coral formations in North African Cretaceous carbonate platforms, and their correlations, and to integrate these data with other studies around the Mediterranean; (2) to place the findings in a global context, noting both similarities with other regions of platform development as well as local differences, and (3) exploring possible reasons for these; and to help promote the creation of a vibrant peri-Mediterranean collaborative research community, embracing researchers from the entire region, to carry forward this ambitious research programme. Twenty-two presentations (oral and poster) provided both topical reviews (covering rudist evolution, and ecology, mineralogical changes, applications of strontium isotope, and graphic correlation methods, and platform typology) as well as regional syntheses (Tunisian reservoirs, Moroccan platform history, Tunisian platforms and rudist/coral facies, Algerian platforms, and Egyptian platforms). Fifteen of these presentations are expanded here as papers. The workshop was attended by 24 academic staff, 4 geologists from the oil industry, plus several observers and students.
This thesis presents an important step towards a deeper understanding of naturally fractured carbonate reservoirs (NFCRs). It demonstrates the various kinds of discontinuities using geological evidence, mathematical kinematics model and computed tomography and uses this as a basis for proposing a new classification for NFCRs. Additionally, this study takes advantage of rock mechanics theory to illustrate how natural fractures can collapse due to fluid flow and pressure changes in the fractured media. The explanations and mathematical modeling developed in this dissertation can be used as diagnostic tools to predict fluid velocity, fluid flow, tectonic fracture collapse, pressure behavior during reservoir depleting, considering stress-sensitive and non-stress-sensitive, with nonlinear terms in the diffusivity equation applied to NFCRs. Furthermore, the book presents the description of real reservoirs with their field data as the principal goal in the mathematical description of the realistic phenomenology of NFCRs.
This book presents experimental results and theoretical advances in the field of ultra-low-cycle fatigue failure of metal structures under strong earthquakes, where the dominant failure mechanism is ductile fracture. Studies on ultra-low-cycle fatigue failure of metal materials and structures have caught the interest of engineers and researchers from various disciplines, such as material, civil and mechanical engineering. Pursuing a holistic approach, the book establishes a fundamental framework for this topic, while also highlighting the importance of theoretical analysis and experimental results in the fracture evaluation of metal structures under seismic loading. Accordingly, it offers a valuable resource for undergraduate and graduate students interested in ultra-low-cycle fatigue, researchers investigating steel and aluminum structures, and structural engineers working on applications related to cyclic large plastic loading conditions.
This single-volume thoroughly summarizes advances in the past several decades and emerging challenges in fundamental research in geotechnical engineering. These fundamental research frontiers are critically reviewed and described in details in lights of four grand challenges our society faces: climate adaptation, urban sustainability, energy and material resources, and global water resources. The specific areas critically reviewed, carefully examined, and envisioned are: sensing and measurement, soil properties and their physics roots, multiscale and multiphysics processes in soil, geochemical processes for resilient and sustainable geosystems, biological processes in geotechnics, unsaturated soil mechanics, coupled flow processes in soil, thermal processes in geotechnical engineering, and rock mechanics in the 21st century.
The ruby is the world's most precious and rare stone. For the ancient Hindus, the ruby was Rajnapura: the Gem of Gems, at whose heart surges an eternal, unquenchable flame. Yet, for all its rarity and beauty, the ruby has always been a slightly sinister stone. Indian legend says the ruby was born from the blood of a demon. Indeed, the ruby is very close to a wild, living being: fiery, passionate, and dangerous. It has been at the center of love and wars, a symbol of passion, greed, and strong magic. Ancient sages and modern crystal healers have credited it with strange powers--from the granting of prophetic insight to protecting one from bullets. It has long been part of the human journey: coveted, fought over, and feared. In Fire and Blood, Morgan considers all the beautiful and terrifying facets of this magnificent stone: scientific, economic, mythological, and spiritual. She discusses the great stones and great heists of the ruby world--and the famous fakes, too--the great Black Prince and renowned Timur. The book closes with a discussion of the making of synthetic rubies and the laser beam.
"Natural Gas Hydrates: Experimental Techniques and Their Applications" attempts to broadly integrate the most recent knowledge in the fields of hydrate experimental techniques in the laboratory. The book examines various experimental techniques in order to provide useful parameters for gas hydrate exploration and exploitation. It provides experimental techniques for gas hydrates, including the detection techniques, the thermo-physical properties, permeability and mechanical properties, geochemical abnormalities, stability and dissociation kinetics, exploitation conditions, as well as modern measurement technologies etc. This book will be of interest to experimental scientists who engage in gas hydrate experiments in the laboratory, and is also intended as a reference work for students concerned with gas hydrate research. Yuguang Ye is a distinguished professor of Experimental Geology at Qingdao Institute of Marine Geology, China Geological Survey, China. Professor Changling Liu works at the Qingdao Institute of Marine Geology, China Geological Survey, China.
This book offers a new framework that facilitates the development of more intelligent systems and methods for data analysis and international information sharing, such as the use of satellite imaging and geospatial data to predict changes in weather conditions and shifts in water levels, and to assess the extent of the forest cover remaining on Earth that is visible from space. It brings together the many aspects of science and technology, as well as formula and analytical approaches required for more informed decision-making. It also highlights the vital importance of understanding the technological, economic and social dimensions of environmental projects that have short-term results and long-term impacts. It is unique in that it clearly distinguishes between environmental project management (EnvPM) and green project management (GreenPM), and presents an amalgamation of environmental management and project management concepts, using geospatial methods to form an EnvPM concept. The book sets a benchmark for the professionalism with which environmental projects should be planned, executed, monitored, assessed and delivered. While primarily intended for professionals responsible for the management of environmental projects or interested in improving the overall efficiency of such projects, it is also a useful handbook for managers in the private, public and non-for-profit sectors. It is a valuable resource for students at both undergraduate and master's levels and an indispensable guide for anyone wanting to develop their skills in modern project management, environmental management and geospatial techniques. ``We are the first generation to feel the impact of climate change, and the last generation that can do something about it.'' US President Obama's address to the United Nations on Climate Change and Global warming (2015) hison: This book provides an in-depth, well-researched and science-based approach to applying key project-management and spatial tools and practices in environmental projects. An important read for leaders considering projects that balance social-economic growth against minimising its ill-effects on Planet Earth. - Todd Hutchison, Global Chairman of Peopleistic group.
This book covers exploration and evaluation practices for various types of complex reservoirs, and summarizes a series of practical and effective techniques and methods. For example, it shows how, by integrating multiple types of new logging technology, complex reservoir petrophysics evaluation can be performed using high-precision core experiment data and quantitative logging interpretation; and demonstrates how the technology of sporopollen assemblage and palynofacies analysis can improve the time precision of sequence stratigraphy and the quantitative study level of sedimentary facies, respectively. It discusses how reservoir lateral prediction and vertical resolution can be substantially improved by integrating fracture prediction and geostatistical inversion; and presents innovative log interpretation charts for the lithological identification of metamorphic rocks, e.g. GR-DEN crossplot and Impedance-Resistivity crossplot. To support the main content, the book features a wealth of high-resolution, thin- section images, quantitative illustrations of palynofacies composition, multi-property overlapping map set and quantitative tables. It offers an essential reference guide for researchers in geological exploration and evaluation, and will also appeal to a broad readership, from engineering technicians to advanced graduate students in related areas.
"GPR Remote Sensing in Archaeology "provides a complete description of the processes needed to take raw GPR data all the way to the construction of subsurface images. The book provides an introduction to the theory of GPR by using a simulator that shows how radar profiles across simple model structures look and provides many examples so that the complexity of radar signatures can be understood.It continues with a review of the necessary radargram signal processes needed along with examples. The most comprehensive methodology to construct subsurface images from either coarsely spaced data using interpolation or from dense data from multi-channel equipment and 3D volume generation is presented, advanced imaging solutions such as overlay analysis are introduced, and numerous worldwide site case histories are shown. The authors present their studies in a way that most technical and non-technical users of the equipment will find essentialsfor implementing in their own subsurface investigations."
Interest in water will continue to grow for a long time to come. It will continue to spread over a large number of disciplines and technologies. Research into water in all its aspects has become so diverse that even those with a direct interest find it impossible to keep up with the original literature beyond a very limited range. On the other hand, scientists want to keep in touch with a wide spectrum of basic and applied research on water and the role played by aqueous solvents in physical, chemical, biological, technological and environmental processes. Water Science Reviews contains three or four critical state-of-the-art reviews of the type previously published in the seven volume work Water -A Comprehensive Treatise. Some reviews update previously published topics, while others feature areas of Water Sciences that have never yet been reviewed. A common focus is the central position adopted by water in the systems and processes described.
Founded on the work of the renowned Advanced Combustion Engineering Research Center, the authors document and integrate current knowledge of the organic and inorganic structure of coal and its reaction processes. With the urgent need for cleaner, more efficient use of this worldwide fuel, their work will set a clear course for future research.
The application of surface geochemical methods to finding petroleum is based on the detection of hydrocarbons in the soil that have leaked from a petroleum reservoir at depth. While the "seal" over the deposit was once considered impermeable, surface geochemistry data now show that such leakage is a common occurrence. Despite its simplicity and low costs, surface geochemistry remains controversial because, until now, there was no objective and in-depth treatment of the various methods of surface geochemistry for oil exploration. Written by a successful oil finder, this practical guide: surveys a broad array of surface geochemistry techniques, from soil gases to microbiology, and provides clear strategies for applying them to the high-stakes art of petroleum exploration; offers numerous case studies, both successes and failures, to show the strengths and weaknesses of different approaches; examines statistical and spatial variation, surveys, and models in surface geochemistry, demonstrating how each analytical tool can be used to optimize accuracy; integrates surface geochemistry data interpretation with data from conventional methods of oil exploration, and considers the economics of surface geochemical approaches; and discusses key topics that have been neglected in the literature, such as grid design and the effects of soils. Geologists, geophysicists, geological engineers, and exploration managers involved in petroleum exploration will gain valuable insights from this volume. By presenting and evaluating each method of surface geochemistry in a neutral tone, this volume enables the reader to select and employ these methods with greater confidence.

How has exploration for minerals evolved in recent years? Is it as productive an activity as it once was? Why have changes occurred? Roderick G. Eggert explores these and other questions about the complex set of circumstances surrounding metallic mineral exploration. Originally published in 1987, Eggert documents trends in the level and the distribution of expenditures by mining companies for metallic mineral exploration and examines a number of factors that may be responsible for these trends. This significant study serves as a handy introduction to the subject for students interested in environmental studies, natural resources, and economics.
Is Gaia becoming Thanatia, a resource exhausted planet? For how long can our high-tech society be sustained in the light of declining mineral ore grades, heavy dependence on un-recycled critical metals and accelerated material dispersion? These are all root causes of future disruptions that need to be addressed today.This book presents a cradle-to-cradle view of the Earth's abiotic resources through a novel and rigorous approach based on the Second Law of Thermodynamics: heat dissipates and materials deteriorate and disperse. Quality is irreversibly lost. This allows for the assessment of such depletion and can be used to estimate the year where production of the main mineral commodities could reach its zenith. By postulating Thanatia, one acquires a sense of destiny and a concern for a unified global management of the planet's abiotic resource endowment.The book covers the core aspects of geology, geochemistry, mining, metallurgy, economics, the environment, thermodynamics and thermochemistry. It is supported by comprehensive databases related to mineral resources, including detailed compositions of the Earth's layers, thermochemical properties of over 300 substances, historical energy and mineral resource inventories, energy consumption and environmental impacts in the mining and metallurgical sector and world recycling rates of commodities.
The book reveals the changing dynamics of the helium industry on both the supply-side and the demand-side. The helium industry has a long-term future and this important gas will have a role to play for many decades to come. Major new users of helium are expected to enter the market, especially in nuclear energy (both fission and fusion). Prices and volumes supplied and expected to rise and this will prompt greater efforts towards the development of new helium sources and helium conservation and recycling.
Himalaya, the world's most prominent mountain system of the world is a source of sustainence for the social, cultural and economic development of population across different countries. Unscientific, small-scale mining for harnessing reounrces including minerals has caused ecosystem damage. Therefore, an integrated and holistic approach to deal with the resource management is required. This book makes a focussed effort to explain how mining in the Himalaya is practiced with discussions pertaining to critiques and lacunas of mining and environmental practices. Status of mining practices in Himalaya is included along with the legal/environmental repercussions of mining.
Utah's Uinta Basin contains one of the largest oil shale resources in the United States. This book examines many of the issues surrounding oil shale development in the Uinta Basin. Focusing on research conducted by investigators associated with The University of Utah's Institute for Clean and Secure Energy (ICSE), the chapters in this book build on each other across a range of scales and of disciplines to present a comprehensive picture of the opportunities and challenges facing this nascent industry. Scales range from the molecular analysis of kerogen to the basin-scale analysis of oil shale geology. Legal, policy, geologic, chemical, economic, and engineering perspectives provide insight into the nature of the Uinta Basin oil shale resource and the potential costs (both financial and environmental) of its extraction. This book integrates the various analyses in two ways. First, the Skyline 16 oil shale core, which was drilled in the Uinta Basin as part of this research, was the source of samples for much of the work that is discussed in this book. Second, the latter chapters of this book incorporate models and data from the earlier chapters to (1) produce a suite of in situ simulation scenarios that study the effect of well arrangement on energy ratio and (2) evaluate costs and air quality issues associated with these scenarios.
This is the first book to revisit geotechnical site characterization from a probabilistic point of view and provide rational tools to probabilistically characterize geotechnical properties and underground stratigraphy using limited information obtained from a specific site. This book not only provides new probabilistic approaches for geotechnical site characterization and slope stability analysis, but also tackles the difficulties in practical implementation of these approaches. In addition, this book also develops efficient Monte Carlo simulation approaches for slope stability analysis and implements these approaches in a commonly available spreadsheet environment. These approaches and the software package are readily available to geotechnical practitioners and alleviate them from reliability computational algorithms. The readers will find useful information for a non-specialist to determine project-specific statistics of geotechnical properties and to perform probabilistic analysis of slope stability.
This monograph addresses the legal and policy issues relating to the commercial exploitation of natural resources in outer space. It begins by establishing the economic necessity and technical feasibility of space mining today, an estimate of the financial commitments required, followed by a risk analysis of a commercial mining venture in space, identifying the economic and legal risks. This leads to the recognition that the legal risks must be minimised to enable such projects to be financed. This is followed by a discussion of the principles of international space law, particularly dealing with state responsibility and international liability, as well as some of the issues arising from space mining activities. Much detail is devoted to the analysis of the content of the common heritage of mankind doctrine. The monograph then attempts to balance such interests in creating a legal and policy compromise to create a new regulatory regime.
Originally published in 1984. This book addresses the economics of the changing mineral industry, which is highly affected by energy economics. The study estimates, in quantitative terms, the short- to mid-term consequences of rising energy prices alongside falling ore quality for the copper and aluminum industries. The effects of changing cost factors on substitution between metals is assessed as is the potential for relying on increased recycling. Copper and aluminum industry problems should be representative of those faced by the mineral processing sector as a whole. Two complex econometric models presented here produce forecasts for the industries and the book discusses and reviews other econometric commodity models. |
