As is now generally accepted mankinda (TM)s burning of fossil fuels has resulted in the mass transfer of greenhouse gases, like CO2, to the atmosphere and a measurable change in the global climate. While the reduced use of fossil fuels must be our ultimate goal in order to reverse this trend, short to medium term solutions are needed which can make an impact today. Various CO2 abatement strategies have been proposed, with deep geological storage being one of the most promising. The present volume organises presentations given by leading international researchers at a NATO Advanced Research Workshop (held in Tomsk, Russia in November of 2004) on the state-of-the-art of geological storage of CO2. The book is divided into 5 parts. Part 1 provides background by describing how human activities are modifying the atmosphere in industrially-active areas in Siberia. Part 2 outlines the innovative idea of using deep permafrost layers as either impermeable boundaries below which CO2 can be injected or as a cooling source for the formation CO2 clathrates. Part 3 describes recent studies conducted on naturally occurring CO2 reservoirs, sites which have the potential to help us understand the possible long-term evolution of CO2 storage sites. Part 4 outlines various industrial-scale applications of CO2 geological storage and shows it to be technically practical, economically feasible and, to date, very safe. Finally Part 5 gives us a view of the future, showing how energy uses are predicted to change over the next 50 years and how the public must be involved in any future decisions regarding climate change abatement.

This book presents the fundamental principles of thermodynamics for geosciences, based on the author 's own courses over a number of years. Many examples help to understand how mineralogical problems can be solved by applying thermodynamic principles.

This is the first book entirely devoted to travertine, a material in use for over 4000 years. The single-author work is a valuable reference source for travertine, covering all aspects of travertine origins, formation, composition, flora and fauna, occurrence and utilisation, as well as covering allied continental carbonates such as lake marls, calcretes and beachrocks.
Travertine, some forms of which are often known as a ~tufaa (TM), is of particular significance as a source of environmental information (fossils and isotope geochemistry), often permitting the reconstruction of past environments. Reviews of dating techniques, classification and geomorphology are included and the author attempts to provide an unbiased but critical appraisal of current models of travertine formation.
Currently, travertine is in great demand as a building and ornamental stone. It has also been exploited in unconventional ways, such as a ~petrifying springsa (TM) and by way of unusual and little known artistic techniques. Scaling of pipes and boilers is often the result of processes allied to travertine formation. The phenomenon is described parallel to methods of scale elimination and compared with natural processes where travertine formation is inhibited. Travertine sites are of special scientific interest, with their rich and often unique floras and faunas displaying their unique biodiversity, and their unusual and often fragile biota. Conservation issues are discussed, together with the description of travertine fossils and occurrences throughout the geological record.
The content will be of interest to carbonate sedimentologists, hydrobiologists, palaeoclimatologists, physicalgeographers, water treatment engineers, astrobiologists, architects, and sculptors.

Here is a comprehensive and up to-do-date presentation of the origins, and properties of clay minerals at the Earth?'s surface. The text reviews the relatively simple laws that govern the chemical or isotopic composition and the crystalline structure of clays, and then discusses their genesis and alteration. Concluding chapters show that clay minerals can form in variety of different environments: meteorites, lavas, subduction zones, among others.

This monograph examines the mineralogy of illite, the most common clay mineral, as a unifying theme for understanding problems of the surface environment and environmental change. The volume begins with a careful analysis of the structure and transformation of illite. Using illite as the frame, the authors describe problems in soil chemistry, clay stability and clay kinetics in sedimentary rocks.

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.

Coal and Coalbed Gas: Future Directions and Opportunities, Second Edition introduces the latest in coal geology research and the engineering of gas extraction. Importantly, the second edition examines how, over the last 10 years, research has both changed focus and where it is conducted. This shift essentially depicts "a tale of two worlds"—one half (Western Europe, North America) moving away from coal and coalbed gas research and production towards cleaner energy resources, and the other half (Asia–Pacific region, Eastern Europe, South America) increasing both research and usage of coal. These changes are marked by a precipitous fall in coalbed gas production in North America; however, at the same time there has been a significant rise in coal and coalbed gas production in Australia, China, and India. The driver for higher production and its associated research is a quest for affordable energy and economic security that a large resource base brings to any country like Australia’s first large-scale coalbed gas to liquid natural gas projects supplying the demand for cleaner burning LNG to the Asian-Pacific region. Since the last edition of this book, global climate change policies have more forcibly emphasized the impact of methane from coal mines and placed these emissions equal to, or even more harmful than, CO2 emissions from fossil fuels in general. Governmental policies have prioritized capture, use, and storage of CO2, burning coal in new highly efficient low emission power plants, and gas pre-drainage of coal mines. The Organization for Economic Cooperation and Development (OECD) countries and China are also introducing new research into alternative, non-fuel uses for coal, such as carbon fibers, nanocarbons, graphene, soil amendments, and as an unconventional ore for critical elements. New to this edition: Each chapter is substantially changed from the 1st edition including expanded and new literature citations and reviews, important new data and information, new features and materials, as well as re-organized and re-designed themes. Importantly, three new chapters cover global coal endowment and gas potential, groundwater systems related to coalbed gas production and biogenic gas generation as well as the changing landscape of coal and coalbed gas influenced by global climate change and net-zero carbon greenhouse gas emissions. FOREWORD When I reviewed the first edition of this book, my initial thought was, "Do we need another book on coal geology?" and then I read it and realised, "Yes, we need this book" and my students downloaded copies as soon as it was available. So now we come to 2023, and a lot has happened in the past decade. For a different reason we might ask if we still need this book, or even coal geoscientists and engineers, as the world aims for rapid decarbonisation of the energy sector and a reduction of coal as a feedstock for industrial resources, like steel manufacture. Natural gas is earmarked as a transition fuel to enable the shift to renewables. In some basins, the source of that gas is directly from coalbed gas production or from conventional reservoirs that were charged by coal and terrestrial organic source rocks. Although the transition is escalating, there are projections that coal will remain part of our future, even after 2050, and can also provide alternative non-fuel resources (e.g., critical elements and carbon-based nanomaterials). Between now and then, we’d best ensure that we extract and utilise coal and coalbed gas as efficiently and safely as possible, that we mitigate any environmental and social impact of the process, and that we improve our certainty of predicting the behaviour of the material and material impacts. To do this we need to understand coal as a material and the inherent variability of its quality and behaviour as a source rock and host of coalbed gas. One can change the technologies but not the geological ground conditions or coal character of the targeted resource. The authors have taken on this ambitious endeavour during their careers and have attempted to capture their knowledge gained from first-hand experience in countries around the world and comprehensive review of published material, within this book. At least three generations of knowledge are drawn upon here. Tim Moore was a student of both Romeo Flores and his supervisor John Ferm, who was the "Warrior of Gentleness" when it came to coal research, teaching, and supervision. This book also reflects the broad and multidisciplinary aspects of coal geology and coal science and provides the tenets for one to understand different disciplines and how they interact to form an integrated view of the resource—technically, economically, and politically. Each chapter takes the reader through different concepts, first setting the scene by examining the status of coal and coalbed gas in a carbon-conscious world, then looking at the science behind coal as a source of gas and as a reservoir- in its own right. Further reading leads to learning about geological settings and the processes through time that led to present-day endowments around the globe and this theme continues throughout the book with detailed examples from different countries. Personally, I like the emphasis on the depositional environments that lead to peat accumulation and preservation—it’s all about the ingredients—which leads nicely into the world of coal macerals and minerals, and why they matter. Coalification and its role in changing the chemistry and material properties of coal is covered from a reservoir perspective, as is the role of biogenic processes. These have produced some of the enormous gas resources we exploit today and could also provide a future circular economy for neo-biogenic gas. The role of groundwater in this past and potentially future endeavour is presented, along with possible adverse effects where there is unexpected communication with regional and local aquifers and surface assets that detract from environmental and social licence. In addition to describing the geology and engineering technologies required to explore for, access, and utilise these resources, the book also provides insights into geostatistical and economic modelling for reserves estimation and challenges as reservoirs become more geologically and politically complex for extraction and alternatively, for injection and carbon sequestration. The final chapters revisit and integrate concepts presented in the book in order to examine global gas production and the geographic shifts in production and research that have occurred over the past decade(s). The also show how government and the market play a role, and project future trends. The authors provide discussion points for the outlook of coal as a fuel feedstock in a carbon-constrained world and the ongoing search for options and alternative non-fuel uses of coal while highlighting the important role that coal and coalbed gas still play during the transition period and beyond. There is much to learn from this book, which is based on decades of observing and interpreting patterns and trends in coal and coal-bearing basins. There is a growing trend towards using machine learning and artificial intelligence to find patterns in data and provide solutions. I’d suggest that domain intelligence, such as that provided in this book, is critical to supervising this process and is required for understanding and validating the outputs upon which many decisions are made and will continue to be made in the future. So yes, we need this book and I invite you to read, learn, and form your own ideas. If you find any gaps—write about them. Joan S.

The book reviews the geological, mineralogical, geochemical and petrological characteristics of indium-bearing ore deposits. Furthermore it develops a general metallogenic concept for indium in identifying the essential enrichment processes and their economic significance. It represents the first comprehensive study on the metallogeny of indium and covers economic aspects including production and use. Careful geological and mineralogical descriptions are given for representative examples of different deposit types with most significant characteristics being summarized at the end of each chapter.

A 'soft-rock' petroleum-type approach to exploration for 'hard-rock' minerals in sedimentary basins D. Taylor I. Introduction Several major groups of ore deposits are found as tabular, stratiform bodies or as cross- cutting but essentially stratabound deposits within sedimentary basins. Important exam- ples are oxide and carbonate ores of iron and manganese, copper and zinc-lead sulphides and gold-uranium deposits. Where the host basins have been strongly in- verted and deeply eroded and the mineralized horizons brought to outcrop, the laterally extensive nature of the mineralization usually results in outcrop or subcrop of the ore itself. Direct detection by geological or geochemical prospecting is then possible. Major deposits also occur in basins which have not been strongly deformed and deeply eroded as non-outcropping sub-horizontal sheets (Polish Kupferschiefer deposits of the fore-Sudetic Monocline) or linear belts (Vibumam Trend, Missouri, Admiral Bay, NW Australia). I believe that both the Polish Kupferschiefer and Admiral Bay de- posits were found by chance during oil and gas exploration, and deposits of this type are similar in attitude and dimensions to small-medium size oil and gasfields.

Since the dissolution of the Soviet Union almost a decade ago, there has been rapid evolution of interactions between the Western nations and individual countries of the former Soviet Union. As part of that interaction, the autonomous independent Republic of Azerbaijan through its scientific arm, the Geological Institute of the Azerbaijan Academy of Sciences under the Directorship of Academician Akif Ali-Zadeh and Deputy Director Ibrahim Guliev, arranged for personnel to be seconded to the University of South Carolina. The idea here was to see to what extent a quantitative understanding could be achieved of the evolution of the Azerbaijan part of the South Caspian Basin from dynamical, thermal and hydrocarbon perspectives. The Azeris brought with them copious amounts of data collected over decades which, together with the quantitative numerical codes available at USC, enabled a concerted effort to be put forward, culminating in two large books (Evolution of the South Caspian Basin: Geological Risks and Probable Hazards, 675 pps; and The South Caspian Basin: Stratigraphy, Geochemistry, and Risk Analysis, of which were published by the Azerbaijan Academy of 472 pps. ) both Sciences, and also many scientific papers. Thus, over the last four to five years an integrated comprehensive start has been made to understand the hydrocarbon proneness of the South Caspian Basin. In the course of the endeavor to understand the basinal evolution, it became clear that a variety of natural hazards occur in the Basin.

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.

Convective heat tranfer is the result of fluid flowing between objects of different temperatures. Thus it may be the objective of a process (as in refrigeration) or it may be an incidental aspect of other processes. This monograph reviews in a concise and unified manner recent contributions to the principles of convective heat transfer for single- and multi-phase systems: It summarizes the role of the fundamental mechanism, discusses the governing differential equations, describes approximation schemes and phenomenological models, and examines their solutions and applications. After a review of the basic physics and thermodynamics, the book divides the subject into three parts. Part 1 deals with single-medium transfer, specifically with intraphase transfers in single-phase flows and with intramedium transfers in two-phase flows. Part 2 deals with fluid-solid transfer processes, both in cases where the interface is small and in cases where it is large, as well as liquid-liquid transfer processes. Part 3 considers three media, addressing both liquid-solid-solid and gas-liquid-solid systems.

Coalbed gas has been considered a hazard since the early 19th century when the first mine gas explosions occurred in the United States in 1810 and France in 1845. In eastern Australia methane-related mine disasters occurred late in the 19th century with hundreds of lives lost in New South Wales, and as recently as 1995 in Queensland's Bowen Basin. Ventilation and gas drainage technologies are now in practice. However, coalbed methane recently is becoming more recognized as a potential source of energy; rather than emitting this gas to the atmosphere during drainage of gassy mines it can be captured and utilized. Both economic and environmental concerns have sparked this impetus to capture coalbed methane. The number of methane utilization projects has increased in the United States in recent years as a result, to a large extent, of development in technology in methane recovery from coal seams. Between 1994 and 1997, the number of mines in Alabama, Colorado, Ohio, Pennsylvania, Virginia, and West Virginia recovering and utilizing methane increased from 1 0 to 17. The Environmental Protection Agency estimates that close to 49 billion cubic feet (Bet) of methane was recovered in 1996, meaning that this amount was not released into the atmosphere. It is estimated that in the same year total emissions of methane equaled 45. 7 Bcf. Other coal mines are being investigated at present, many ofwhich appear to be promising for the development of cost-effective gas recovery.

The perturbation of the earth by mankind causes earthquakes in a variety of situations. This phenomenon continues to be a major concern to engineers and scientists concerned with the mitigation of the consequences of this seismicity, as well as better understanding the processes at its origin. The present volume contains twelve papers from six countries, dealing with observations of triggered and induced seismicity in four continents. The reported cases include seismicity due to hard-rock mines, coal mines, underground research facilities for nuclear waste disposal, water injections, reservoirs, acquifers and oil fields. This volume provides case studies of previously unavailable observations of this phenomenon, investigations of the cause and source mechanism of seismic events, studies of source location distributions, determinations of seismic source parameters, cases of the use of such parameters in assessing rockburst hazard in mines, and measurements of velocity an attenuation properties of rock masses. The present collection of papers provides an excellent indication of the current state of the art and new developments in this area of research.

This book introduces the concepts and methods of spatial statistics to geologists and engineers working with oil and gas data, and covers all of the most commonly encountered geostatistical methods for estimation and simulation. Topics include calculation and modeling of semivariograms, linear methods of kriging, cokriging, nonlinear methods such as indicator kriging and disjunctive kriging, and conditional simulation, including sequential indicator simulation, sequential Gaussian simulation, and simulated annealing. Semivariogram models range from very simple to complex. All of the fundamental semivariogram models are illustrated, along with anisotropic models, hole effects, geometric and zonal models, and the mechanics of fitting models. For each geostatistical method treated in detail, the author introduces necessary theory and background, describes how the method works, the steps a user must go through, and problems a user might encounter. The emphasis throughout is on what the practitioner needs to know, and the results that can be expected. The book is replete with examples in two and three dimensions, using real-world data such as porosity and permeability, gas production, structural elevation of a reservoir, and seismic information. Geostatistics and Petroleum Geology will be an invaluable advanced-level text for students on petroleum engineering and geosciences courses, as well as an important reference for petroleum geologists and petroleum engineers in oil companies worldwide.

This advanced text treats the transformation of sediment into rock, a fundamental process which directly determines the storage and transmissibility properties of reservoirs and seals in hydrocarbon and groundwater systems and in strata-bound mineralization. Attention is paid to diagenetic data from classical petrography and geochemistry and the statistical techniques required to establish its significance and assist in its interpretation. Historically under-used methodologies such as mass balance calculations and the study of modern aquifer systems for understanding rock properties below ancient unconformities are also emphasised. New ground is broken by discussing physico-chemical processes and controls against a background of geological and hydrological evolution of sedimentary basins. In particular, this reconciles the importance of chemical kinetics in shallow, low temperature environments with that of equilibrium thermodynamics in deep, high temperature environments for the evolution of diagenetic products. It also allows detailed treatment of the economically important topic of the loss of porosity with depth. Throughout, the emphasis is on the quantitative description and evaluation of the time-variant parameters controlling heat, fluid and mass transport in porous rock, and upon their integration using mathematics. A full mathematical background is provided and all the basic equations are rigorously derived. Audience: This book will prove essential reading for postgraduate academics and industrial professionals whose work involves predicting rock properties for basin evaluation, and is expected to stimulate new diagenetic research.

This book, in which the term granite is taken in its broadest sense, collates the most innovative contributions that were presented at the EUG 8 Meeting, X12 Symposium, held in Strasbourg during April 1995. It covers a broad range of topics related to the physical aspects of granite magmatism, which are largely under-represented in comparison with chemical-oriented approaches. Nineteen papers span the range from physical properties of granitic material to several pluton case studies. The first part, Melt and Magmas: Properties and Segregation', deals mainly with the physical properties and segregation of melts and magmas, including laboratory and field data. The second part, Fabrics in Granites', develops some lively aspects of present-day granite geology, such as magmatic fabrics at all scales, and analogue and numerical experiments aimed at modelling magmatic fabrics. The third part, Emplacement of Granite Plutons: Case Studies', begins with a general consideration of syntectonic granites, includes a review of the shape of plutons as inferred from combined fabric and gravity data, and comprises some spectacular examples of plutons emplaced along shear zones, in Spain, Sierra Nevada -California- (see the cover page), Nigeria, and Brazil, or emplaced along subduction zones, in Japan. Granite is the most abundant rock on the continental crust, and this unique text is devoted entirely to the understanding of its origins and emplacement by studying its internal structures. The book is particularly well-illustrated, and almost all the illustrations are original. It will serve as an invaluable reference for geologists, petrologists, geophysicists interested in the development of thecontinental crust and, more generally, for earth scientists.

""" This book has been written as a guide to the management and use of formulated feeds in intensive fish and shrimp culture. While its focus is on the use of commercially pro duced feeds in intensive production systems, it is anticipated that many of the practical issues covered will be of equal interest to those fish farmers who make their own feeds and to those who use formulated feeds in less intensive systems. Feeds and feeding are the major variable operating costs in intensive aquaculture and the book is primarily in tended to aid decision making by fish farm managers in areas of feeding policy. The dramatic increases in aquaculture production seen over the past 15 years have been made possible, in large part, by gains in our understanding of the food and feed ing requirements of key fish and shrimp species. A global aquaculture feeds industry has developed and a wide range of specialist feeds is now sold. The new options in feeds and feeding systems, which are becoming available, necessitate continual review by farmers of their feeding policies, where choices must be made as to appropriate feed types and feeding methods. While growth rates and feed conversion values are the prime factors of interest to farmers, other important issues, such as product qualiry and environmental impacts of farm effluents, are also directly related to feed management practices."

Tuzo is the never-before-told story of one of Canada's most influential scientists and the discovery of plate tectonics, a pivotal development that forever altered how we think of our planet. In 1961, a Canadian geologist named John "Jock" Tuzo Wilson (1908-1993) jettisoned decades of strongly held opposition to theories of moving continents and embraced the idea that they drift across the surface of the Earth. Tuzo tells the fascinating life story of Tuzo Wilson, from his early forays as a teenaged geological assistant working on the remote Canadian Shield in the 1920s to his experiences as a civilian-soldier in the Second World War to his ultimate role as the venerated father of plate tectonics. Illuminating how science is done, this book blends Tuzo's life story with the development of the theory of plate tectonics, showing along the way how scientific theories are debated, rejected, and accepted. Gorgeously illustrated, Tuzo will appeal to anyone interested in the natural world around them.
