This book describes the nature and origin of the Macraes gold deposit. It also documents the key features of this spectacular deposit for a wide range of professionals in the resource geology community. This world-class gold deposit has been a spectacular geological and economic success story, as it has developed from a small historical gold mine in discontinuous quartz veins measuring only meters to a large-scale mine in deposits spreading over kilometres in extensive disseminated gold-bearing rock.

This book highlights the basics of crystal optics methods and refractive index (RI) measurement techniques in various solids, as well as their scientific and technological applications. In addition to new techniques for cases when traditional techniques are impractical, such as for highly refracting powders, anomalous dispersion of light in the studied solid, or for colloids, it also describes conventional methods of RI measurement.

On a Sustainable Future of the Earth's Natural Resources is divided into three sections, with individual chapters contributed by experts on diff erent facets of the earth sciences, natural resources management and related issues. The first section focuses on the status of Earth's resources; land, water, biota and atmosphere. Reviews on the rate of exploitation and the need to conserve these resources for future sustenance are also covered in this section. Th e following section includes chapters elucidating environmental, ecological, climatological and anthropological pressures on sustained nourishment with the Earth's resources. The last section describes management practices, issues and perspectives on sociological, legal, administrative, ICT and strategic efforts that need to be implemented in order to sustain our natural resources. This book covers a broad spectrum of the Earth's resources and sustenance, offering a comprehensive perspective on their past, present and future.

This thesis deals with Rare Earth Elements (REE), especially with neodymium used in permanent magnets, from a very scientific basis by providing basic research data. Despite the fact that REE are newsworthy and very important elements for a considerable bandwidth of todays' technologies, accompanied by the monopolistic supply-situation and Chinese politics, there are inexplicable data discrepancies about REE which have been recognized frequently but usually have not been addressed accordingly. So this analysis started with the hypothesis that the four application areas, namely computer hard disk drives (HDD), mobile phones, wind turbines and e-mobility (automotive traction), account for about 80% of the global annual neodymium-demand. The research methodology was a laboratory analysis of the composition of used magnets for HDDs and mobile phones and a literature and official report analysis of wind turbine and automotive neodymium use. The result was amazing and the hypothesis had to be withdrawn as these four areas only account for about 20% of neodymium use. This result raises some questions concerning actual use and thus potential recycling options.

This book deals with the rare earth elements (REE), which are a series of 17 transition metals: scandium, yttrium and the lanthanide series of elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium). They are relatively unknown to the wider public, despite their numerous applications and their critical role in many high-tech applications, such as high-temperature superconductors, phosphors (for energy-saving lamps, flat-screen monitors and flat-screen televisions), rechargeable batteries (household and automotive), very strong permanent magnets (used for instance in wind turbines and hard-disk drives), or even in a medical MRI application. This book describes the history of their discovery, the major REE ore minerals and the major ore deposits that are presently being exploited (or are planned to be exploited in the very near future), the physical and chemical properties of REEs, the mineral processing of REE concentrates and their extractive metallurgy, the applications of these elements, their economic aspects and the influential economical role of China, and finally the recycling of the REE, which is an emerging field.

Over the millennia, from stone tools among early foragers to clays to prized metals and mineral pigments used by later groups, mineral resources have had a pronounced role in the Andean world. Archaeologists have used a variety of analytical techniques on the materials that ancient peoples procured from the earth. What these materials all have in common is that they originated in a mine or quarry. Despite their importance, comparative analysis between these archaeological sites and features has been exceptionally rare, and even more so for the Andes. Mining and Quarrying in the Ancient Andes focuses on archaeological research at primary deposits of minerals extracted through mining or quarrying in the Andean region. While mining often begins with an economic need, it has important social, political, and ritual dimensions as well. The contributions in this volume place evidence of primary extraction activities within the larger cultural context in which they occurred. This important contribution to the interdisciplinary literature presents research and analysis on the mining and quarrying of various materials throughout the region and through time. Thus, rather than focusing on one material type or one specific site, Mining and Quarrying in the Ancient Andes incorporates a variety of all the aspects of mining, by focusing on the physical, social, and ritual aspects of procuring materials from the earth in the Andean past.

This book carries out approximate estimates of the costs of implementing ISRU on the Moon and Mars. It is found that no ISRU process on the Moon has much merit. ISRU on Mars can save a great deal of mass, but there is a significant cost in prospecting for resources and validating ISRU concepts. Mars ISRU might have merit, but not enough data are available to be certain. In addition, this book provides a detailed review of various ISRU technologies. This includes three approaches for Mars ISRU based on processing only the atmosphere: solid oxide electrolysis, reverse water gas shift reaction (RWGS), and absorbing water vapor directly from the atmosphere. It is not clear that any of these technologies are viable although the RWGS seems to have the best chance. An approach for combining hydrogen with the atmospheric resource is chemically very viable, but hydrogen is needed on Mars. This can be approached by bringing hydrogen from Earth or obtaining water from near-surface water deposits in the soil. Bringing hydrogen from Earth is problematic, so mining the regolith to obtain water seems to be the only way to go. This will require a sizable campaign to locate and validate useable water resources. Technologies for lunar ISRU are also reviewed, even though none of them provide significant benefits to near-term lunar missions. These include oxygen from lunar regolith, solar wind volatiles from regolith, and extraction of polar ice from permanently shaded craters.

This book is a collection of papers that are devoted to various aspects of interactions between mineralogy and material sciences. It will include reviews, perspective papers and original research papers on mineral nanostructures, biomineralization, micro- and nanoporous mineral phases as functional materials, physical and optical properties of minerals, etc. Many important materials that dominate modern technological development were known to mineralogists for hundreds of years, though their properties were not fully recognized. Mineralogy, on the other hand, needs new impacts for the further development in the line of modern scientific achievements such as bio- and nanotechnologies as well as by the understanding of a deep role that information plays in the formation of natural structures and definition of natural processes. It is the idea of this series of books to provide an arena for interdisciplinary discussion on minerals as advanced materials.

1000 DegreesC) and low pressures (< 2 kb) and typically results in the formation of "burnt" and fused rocks termed buchites, paralavas, clinkers and fulgarites. It is typically associated with shallow basaltic intrusions (contact aureoles, xenoliths,) combustion of carbonaceous matter, lightning strikes, and is also found in meteorites. During pyrometamorphism, the sequence of heating and cooling is greatly condensed favouring the preservation of a variety of stranded reaction microstructures that reflect disequilibrium reaction kinetics with metastable and mineral crystallisation. This second edition includes the latest developments in the study of pyrometamorphism derived from over 60 new references and accompanied with over 20 new illustrations.

Existing views on geodynamics (recharge, migration, discharge) of uids at deep layers of petroliferous basins are summarized. The in ltration and elision th- ries explaining development of uid pressures in deep formations are called into question based on quantitative estimates available for some artesian (petroliferous) basins. Using the West Siberian, Pechora, Terek-Kuma, Bukhara-Karshi, and other petroliferous basins as examples, the stratum-block structure of deep formations is substantiated for strati ed systems of platform in inter- and intramontane depr- sions. It is shown that petroliferous reservoirs at great depths are characterized, regardless of lithology, by largely ssure-related capacity and permeability (clayey rocks included) changeable in space and through geological time. Much attention is paid to development of abnormally high formation pressures. Peculiarities in heat and mass transfer at deep levels are considered for different regions. The energetic formation model substantiated for deep uids explains different anomalies (baric, thermal, hydrogeochemical, mineralogical, and others) at deep levels of platforms. Based on hydrogeodynamic considerations, the theory of oil origin and formation of hydrocarbon elds is proposed. The book is of interest for oilmen, hydrogeo- gists, geologists, and specialists dealing with prospecting of petroliferous deposits as well as industrial, mineral, and thermal waters in deep formations of strati ed sedimentary basins. vii Contents 1 Existing Views on Fluidodynamics in Petroliferous Formations . . 1 References ...11 2 Investigation Methods of Deep Fluidodynamics ...15 2. 1 Methods of Formation Pressure Reducing ...16 2. 2 Assessment of Directions of Density-Variable Fluid Flows by the "Filtration Force" Method ...

This practical step-by-step guide describes the key geological field techniques needed by today's exploration geologists involved in the search for metallic deposits. The techniques described are fundamental to the collection, storage and presentation of geological data and their use to locate ore. This book explains the various tasks which the exploration geologist is asked to perform in the sequence in which they might be employed in an actual exploration project. Hints and tips are give. The steps are illustrated with numerous examples drawn from real projects on which the author has worked. The book emphasizes traditional skills and shows how they can be combined effectively with modern technological approaches.

This book reviews the geochemical and petrological characteristics of potassic igneous rock complexes, and investigates the different tectonic settings in which these rocks occur. The authors provide an overview and classification of these rocks and elucidate the geochemical differences between barren and mineralized potassic igneous complexes. High-K rocks host a number of epithermal gold and porphyry copper-gold deposits. In recent years, there has also been growing recognition of an association of such rocks with iron-oxide copper-gold (IOCG) deposits, intrusion-related gold deposits (IRGDs) and possibly even Carlin-type gold deposits. This book is not only relevant to academic petrologists working on alkaline rocks, but also to exploration geologists prospecting for epithermal gold and/or porphyry copper-gold deposits in modern and ancient terrains. This fourth, updated and expanded edition incorporates new data and references from Africa, Australia, Brazil, China, Greece, Iran, Mongolia, North America, Russia and Turkey, including new maps and sections and new color plates of high-grade gold-copper ore from major deposits hosted by potassic igneous rocks.

The goal of this Third Edition is to update long-term data presented in earlier editions and to generate new syntheses and conclusions about the biogeochemistry of the Hubbard Brook Valley based on these longer-term data. There have been many changes, revelations, and exciting new insights generated from the longer data records. For example, the impact of acid rain peaked during the period of the HBES and is now declining. The longer-term data also posed challenges in that very marked changes in fluxes occurred in some components, such as hydrogen ion and sulfate deposition, calcium and nitrate export in stream water and biomass accumulation, during the almost 50 years of record. Thus, presenting "mean" or "average" conditions for many components for such a long period, when change was so prominent, do not make sense. In some cases, pentads or decades of time are compared to show these changes in a more smoothed and rational way for this long period. In some cases, a single period, often during periods of rapid change, such as acidification, is used to illustrate the main point(s). And, for some elements a unique mass balance approach, allowing the calculation of the Net Ecosystem Flux (NEF), is shown on an annual basis throughout the study.

Human history has often been described as a progressive relinquishment from environmental constraints. Now, it seems, we have come full circle. The ecological irrationalities associated with industrial societies have a lengthy history, and our purpose in the proposed book is not to catalogue this litany of wrongs. Rather, this book is about political responses to global environmental crisis at a crucial turning point in history, by focusing on the political discourses surrounding the tar sands in Alberta, Canada.

In recent years, the increased availability and fidelity of broadband seismic instruments have effectively narrowed the gap between exploration and global seismic applications. Global seismologists are now able to take advantage of high-resolution, often exploration-based, tools to examine rock properties tens to hundreds of kilometers below surface. This book reviews the key assumptions, algorithms and prospects of several important array-based methods in today's global and regional seismic surveys. A short list of topics includes data migration, PP and SS precursors, Radon transform, mantle triplication, P-to-S and S-to-P converted waves, shear-wave splitting, high-resolution seismic tomography, and ambient-noise interferometry. Each approach is presented in a 'cookbook' fashion for easy comparison, implementation and critique by the general readership.

Extensive descriptions of a wide range of key or world-class mineral deposits of China are presented in the context of the country's general geology, tectonic units and mineral systems and their geodynamic evolution within the tectonic framework of the Asian continent. This comprehensive overview, incorporating the latest geological concepts, is the first such coverage written in English by a western expert, and will be of benefit to mineral explorers and miners, as well as to research scientists and students in institutions of higher education. In his compilation of this compendium of Chinese geology and mineral systems, Franco Pirajno draws on first-hand knowledge of China's geology and mineral deposits gained in numerous field visits and research projects with Chinese colleagues from various academic institutions over the past 18 years. First time that a western-based book on China's geology and mineral deposits is published Appropriate for use by the mineral exploration industry Modern English-language geological and mineral deposits information on China Most useful to Western (and Chinese) geoscientists

This book provides a very basic introduction to electron microscopy and energy dispersive spectrometry (EDS). It has the largest compiled collection of EDS spectra ever published and covers most common rock forming minerals. In addition, it provides a key to help the novice wade through the large number of spectra.

With the new global tectonics approach in the Earth Sciences, the quan titative aspects of the dynamics of rock-forming processes came into focus: geologists are no longer satisfied knowing the pressure-tempera ture conditions of the formation of a metamorphic rock or of the emplace ment of a magmatic body, but instead would like to learn the time history of these rocks as well, i. e. , derive the temperature-pressure-time path and relate it to a tectonic process. To achieve this goal, a knowledge of both pressure-temperature-dependent equilibria and the time scales at which these equilibria may be attained are essential. However, the latter kinetic information is much more difficult to retrieve than that on equilibria: whereas equilibria are controlled by state variables, and proper laboratory experiments may be directly applied to equilibrium natural assemblages, kinetics also depends on factors other than state variables, such as grain size, dislocation density, and especially time (rate of heating, duration of annealing, rate of cooling). Extrapolation of kinetic data obtained at high temperatures on laboratory time scales to more realistic lower tempera tures and geological time scales are dangerous because, for example, of possible changes from an intrinsically controlled defect regime to an extrinsic one as temperature is lowered, or from an interface-controlled to a diffusion-controlled reaction mechanism.

This book addresses the processes related to mine abandonment from a hydrogeological perspective and provides a comprehensive presentation of water management and innovative tracer techniques for flooded mines. After an introduction to the relevant hydrogeochemical processes the book gives detailed information about mine closure procedures. The book also includes case studies and hints, and some new methodologies for conducting tracer tests in flooded mines.

There has been a great advance in the understanding of processes of meta morphism and of metamorphic rocks since the last edition of this book appeared. Methods for determining temperatures and pressures have become almost routine, and there is a wide appreciation that there is not a single temperature and pressure of metamorphism, but that rocks may preserve, in their minerals, chemistry and textures, traces of their history of burial, heating, deformation and permeation by fluids. However, this excit ing new knowledge is still often difficult for non-specialists to understand, and this book, like the first edition, aims at enlightenment. I have concen trated on the interpretation of the plate tectonic settings of metamorphism, rather than following a geochemical approach. Although there is an impress ive degree of agreement between the two, I believe that attempting to discover the tectonic conditions accompanying rock recrystallization will more readily arouse the interest of the beginner. I have used a series of case histories, as in the first edition, drawing on my own direct experience as far as possible. This m

This abundantly illustrated book provides a concise overview of our understanding of the entire mantle, its evolution since early differentiation and the consequences of superplumes for earth surface processes. The book's balanced authorship has produced a state-of-the-science report on the emerging concept of superplumes. This presents a new concept to explain catastrophic events on Earth through geologic time.

Perhaps the most striking impression gained by a geologist during twenty years of field work with deformed rocks in many parts of the world is that the minor structures in these rocks are surprisingly uniform in their properties and restricted in their variety. In fact, a relatively short and simple list can include all structures which are both of common occurrence and of use to the structural geologist in his attempts to understand the structure and evolution of a deformed geologic body. The photographs in this book have been selected to illustrate as clearly as possible the obvious characteristics of the common minor structures of deformed rocks. I have tried to make this selection truly representative in spite of two factors that have affected the choice. First, I have included only photographs made during my own field work. No doubt the selection could have been greatly improved in both quality and variety by including photographs made by other geologists. Second, the photographs necessarily reflect my own inte rests and not those of every geologist concerned with deformed rocks. Consequently, for example, great emphasis has been placed on folds, whereas faults and joints are entirely omitted.

In the Spring of 2000 the idea of a consortium of Mediterranean countries support- ing the Italian bid to host the 32nd International Geological Congress took off during ageological fieldtrip on the slopes ofMountVesuviushosted byProf. Bruno D'Argenio (University of Naples) with the sponsorship of SMED(the UNESCO-CNR Office for Scientific and Technological Cooperation with Mediterranean Countries). On that st occasion, the head of the Italian delegation to the coming 31 IGCProf. Gian Battista Vaichampionedthe notionthat - had the bid been accepted - such cooperationshould have not only translated into the participation of the Mediterranean countries in the organization of the future congress, but also should have been a springboard for launching a scientific project focused on the Mediterranean region and whose re- sults had to be presented at the congress. st During the 31 IGCin Riode Janeiro,after the designation of Florence bythe lUGS nd Council as the venue for the 32 IGC,the Mediterranean Consortium was set up. In its full configuration, the Consortium was an association of thirty-one Mediterra- nean and nearbycountries. Alongwith Italy,they are:Albania,Algeria,Austria, Bosnia- Herzegovina, Bulgaria, Croatia, Cyprus, Egypt, France, Greece, Hungary, Iran, Iraq, Israel, Jordan, Lebanon, Libya,Macedonia, Malta,Morocco,Palestine, Romania, Saudi Arabia, Serbia and Montenegro, Slovakia,Slovenia,Spain, Switzerland, Syria,Tunisia, and Turkey. Each member country nominated a National Representative who served as a liai- son between his/her national geological community and the IGCOrganizing Commit- tee.
