Rare-earth intermetallics, also known as lanthanide elements, play an important role in the study of magnetic materials and the development of semi- and super-conducting materials. This handbook provides an up-to-date compilation of crystallographic, physical, and magnetic data on rare-earth intermetallic compounds. Over 20 different structure types are described in detail with an emphasis on how crystal structure can affect magnetic properties. Theoretical models for magnetic interactions are described as well as the impact of crystal electric fields on transport properties, magneto crystalline anistropy and hyperfine interactions. This book provides materials scientists, engineers and physicists with all the critical information needed to use rare-earth intermetallics effectively in the development of new materials.

Handbook on the Physics and Chemistry of Rare Earths is a continuing series of books covering all aspects of rare earth science, including chemistry, life sciences, materials science, and physics. The handbook emphasizes rare earth elements [Sc, Y and the lanthanides (La through Lu)] but, when relevant, information also is included about the closely related actinide elements. The individual chapters are comprehensive, broad, up-to-date critical reviews written by highly experienced invited experts. The series, which was started in 1978 by Professor Karl A. Gschneidner, Jr., combines and integrates both the fundamentals and applications of these elements and now publishes two volumes a year.

The book comprises the proceedings of the 9th Geoscience Conference for Young Scientists co-organized by the Institute of Geology and Geochemistry and the Institute of Mineralogy (Urals Branch of Russian Academy of Sciences) and Ural Federal University and held in Ekaterinburg, Russia, on February 5-8, 2018. The book is devoted to the relevant issues of crystal chemistry and mineral typomorphism; the structure and physico-chemical and technological properties of minerals; the computational modeling of mineral structure and properties.

This book provides a wealth of geomathematical case history studies performed by the author during his career at the Ministry of Natural Resources Canada, Geological Survey of Canada (NRCan-GSC). Several of the techniques newly developed by the author and colleagues that are described in this book have become widely adopted, not only for further research by geomathematical colleagues, but by government organizations and industry worldwide. These include Weights-of-Evidence modelling, mineral resource estimation technology, trend surface analysis, automatic stratigraphic correlation and nonlinear geochemical exploration methods. The author has developed maximum likelihood methodology and spline-fitting techniques for the construction of the international numerical geologic timescale. He has introduced the application of new theory of fractals and multi fractals in the geostatistical evaluation of regional mineral resources and ore reserves and to study the spatial distribution of metals in rocks. The book also contains sections deemed important by the author but that have not been widely adopted because they require further research. These include the geometry of preferred orientations of contours and edge effects on maps, time series analysis of Quaternary retreating ice sheet related sedimentary data, estimation of first and last appearances of fossil taxa from frequency distributions of their observed first and last occurrences, tectonic reactivation along pre-existing schistosity planes in fold belts, use of the grouped jackknife method for bias reduction in geometrical extrapolations and new applications of the theory of permanent, volume-independent frequency distributions.

The international Mont Terri rock laboratory in Switzerland plays a central role in the safety and construction of deep geological nuclear repositories in clay formations.

The book provides a model for structural evolution of the Himalaya with relevant background information so that earth scientists of other specialization will find it easy to comprehend. Hence the book is divided into two parts. The first part describes the basic principles of structural geology that are required to understand the evolutionary model described in the second part.

The book incorporates some of the ignored structural features, e.g. Pre-Himalayan rift tectonics, reactivation of faults, simultaneous development of folds and thrust faults, superposed folds, strike-slip faults developed during the early and superposed deformation, problems with the GPS data, erratic crustal shortening obtained by restoration of deformed sections, etc. The proposed model is essentially based on inversion tectonics and provides answers to some unsolved questions. It describes the accurate structure of the Himalaya as a primary arc. Supporting evidence for the model have also come from model deformation under controlled boundary conditions and anisotropy of magnetic susceptibility studies.

This book describes the Aguablanca Ni-Cu-PGE sulfide deposit, the first, and to date only, mineralization of this type in southwestern (SW) Europe. Since its discovery in 1993, this ore deposit has attracted the attention of the resource geology community due to its unusual geodynamic context, namely an active plate margin. The book focuses on the key features of the deposit and reports on the ore-forming processes that were most important for its formation.

Each spectrum provides information about the occurrence, appearance, associated minerals, its empirical formula, and unit-cell parameters. The book also provides insights into sample preparation and/or spectrum registration methods. It includes IR spectra of 1020 minerals that were not covered in the book "Infrared spectra of mineral species: Extended library" published in 2014 and written by one of the authors. On average, each page provides information on two minerals/compounds. Subsections correspond to different classes of compounds (silicates, phosphates, arsenates, oxides etc.). About 290 new spectra have been obtained, and the remaining 1310 spectra are taken from most reliable literature sources (published over the last 60 years) and are redrawn in a unified style.

This book describes in detail numerous geological sites throughout the mountains of Oman and the United Arab Emirates (UAE) in Eastern Arabia. The region is well known for its oil and gas reserves in the desert interior, and Permian-Mesozoic shelf carbonates exposed in the mountains of the Musandam peninsula, Jebel al-Akhdar and Saih Hatat, where deep wadi canyons provide impressive three-dimensional views into the crust. The region has numerous globally important geological sites, including the world's largest and best-exposed ophiolite complex, the Semail Ophiolite, which is a vast thrust sheet of Cretaceous ocean crust and upper mantle emplaced onto the Arabian continental margin. Other sites include spectacular fossil localities, subduction zone metamorphic rocks (eclogites, blueschists, amphibolites), fold-thrust belts, giant sheath folds and Precambrian salt domes, as well as the huge sand dunes of the Rub al'Khali, the Empty Quarter, and the separate Wahiba (Sharkiyah) sandsea of Eastern Oman. Written by Mike Searle, who has worked on geological research projects throughout Oman and UAE almost every year since 1978, this book describes the field geology of each site and includes a wealth of maps, field photos and diagrams illustrating key features. It also discusses the history of exploration of Arabia and the search for its hidden geological secrets. The book provides the geological basis for the establishment of a series of World Heritage Sites, National GeoParks and Sites of Special Scientific Interest (SSSI) throughout the region. As such, it is of interest to geologists, tourists, mountaineers, trekkers, rock climbers and naturalists.

This edited volume deals with the attempts made by the scientists and practitioners to address contemporary issues in geoenvironmental engineering such as characterization of dredged sediments, geomaterials and waste, valorization of waste, sustainability in waste management and some other geoenvironmental issues that are becoming quite relevant in today's world especially in view of the high urbanization rates, advancement in technologies, and changes in consumption behavior of people. In this regard, wastes generated through the daily activities of individuals and organizations pose many challenges in their management. The volume is based on the best contributions to the 2nd GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2018 - The official international congress of the Soil-Structure Interaction Group in Egypt (SSIGE).

Lithium-cesium-tantalum (LCT) pegmatites are important resources for rare metals. For Cs, only the LCT pegmatites with the zeolite group mineral pollucite at Bikita (Zimbabwe Craton) and Tanco (Superior Province Craton) are of commercial importance. Common characteristics of world-class LCT pegmatite deposits include their Meso- to Neoarchean age and geological setting within greenstone belt lithologies on Archean Cratons. This study presents the first coherent and comparative scientific investigation of five major LCT pegmatite systems from the Yilgarn, Pilbara and Zimbabwe Craton. For the evaluation of their Cs potential and of the genetic concepts of pollucite formation, the pegmatites from Wodgina, Londonderry, Mount Deans and Cattlin Creek were compared to the Bikita pollucite mineralization.  The integration of the new data (e.g., geochronological and radiogenic isotope data) into the complex geological framework: 1) enhances our knowledge of the formation of LCT pegmatite systems, and 2) will contribute to the further exploration of additional world-class LCT pegmatite deposits, which 3) may host massive pollucite mineralisations.

This second edition is fully updated to include new developments in the study of metamorphism as well as enhanced features to facilitate course teaching. It integrates a systematic account of the mineralogical changes accompanying metamorphism of the major rock types with discussion of the conditions and settings in which they formed. The use of textures to understand metamorphic history and links to rock deformation are also explored. Specific chapters are devoted to rates and timescales of metamorphism and to the tectonic settings in which metamorphic belts develop. These provide a strong connection to other parts of the geology curriculum. Key thermodynamic and chemical concepts are introduced through examples which demonstrate their application and relevance. Richly illustrated in colour and featuring end-of-chapter and online exercises, this textbook is a comprehensive introduction to metamorphic rocks and processes for undergraduate students of petrology, and provides a solid basis for advanced study and research.

Study of microstructures is an indispensable component of understanding structural geology of any terrain. A number of ‘new’ microscopic structures such as ‘flanking microstructures’, trapezoid-shaped mineral grains, reversal of ductile shear sense, micro-duplexes, V-pull aparts, and new minerals nucleating inside host minerals have recently been described in individual manuscripts. However, for the sake of brevity, microstructural papers cannot show all possible variation in their morphology. The proposed book aims to present these structures with attractive colour photographs. Each photomicrograph will have a comprehensive caption. The book also presents grain boundary migration, boudins, symptoms of metamorphic retrogression, and how well known shear sense indicators (S-C fabrics, mineral fish etc.) vary in morphology in serial-sections. The target audience is for graduate and postgraduate geosciences students and researchers of structural geology.

Study of structures associated with shear zones is a crucial aspect to understand the deformation mechanism associated with such zones. Shear zones have been emphasized since it will lead to many latest applied studies such as radioactive waste disposal, groundwater flow etc. For the sake of brevity, research papers cannot show all possible variation in structures found in shear zones. The proposed book aims to present some of these structures in great details with attractive colour photographs. Each photograph will have a comprehensive caption.

Thermodynamically constrained averaging theory provides a consistent method for upscaling conservation and thermodynamic equations for application in the study of porous medium systems. The method provides dynamic equations for phases, interfaces, and common curves that are closely based on insights from the entropy inequality. All larger scale variables in the equations are explicitly defined in terms of their microscale precursors, facilitating the determination of important parameters and macroscale state equations based on microscale experimental and computational analysis. The method requires that all assumptions that lead to a particular equation form be explicitly indicated, a restriction which is useful in ascertaining the range of applicability of a model as well as potential sources of error and opportunities to improve the analysis.

This book presents the results of the major EU project Promine. For the first time there is now a European database available on mineral deposits, as well as 3D, 4D and predictive models of major mineral belts in Europe: Fennoscandia (Skelleftea and Vihanti-Pyhasalmi), the Fore-Sudetic basin (Kupferschiefer deposits in Poland and Germany), the Hellenic belt in northern Greece, and the Iberian Pyrite belt and Ossa Morena zone in Spain and Portugal. The book also describes the modelling techniques applied and how different types of software are used for three- and four-dimensional modelling. Furthermore, fundamental descriptions of how to build the database structure of three-dimensional geological data are provided and both 2D and 3D predictive models are presented for the main mineral belts of Europe.

This book presents several intelligent approaches for tackling and solving challenging practical problems facing those in the petroleum geosciences and petroleum industry. Written by experienced academics, this book offers state-of-the-art working examples and provides the reader with exposure to the latest developments in the field of intelligent methods applied to oil and gas research, exploration and production. It also analyzes the strengths and weaknesses of each method presented using benchmarking, whilst also emphasizing essential parameters such as robustness, accuracy, speed of convergence, computer time, overlearning and the role of normalization. The intelligent approaches presented include artificial neural networks, fuzzy logic, active learning method, genetic algorithms and support vector machines, amongst others. Integration, handling data of immense size and uncertainty, and dealing with risk management are among crucial issues in petroleum geosciences. The problems we have to solve in this domain are becoming too complex to rely on a single discipline for effective solutions and the costs associated with poor predictions (e.g. dry holes) increase. Therefore, there is a need to establish a new approach aimed at proper integration of disciplines (such as petroleum engineering, geology, geophysics and geochemistry), data fusion, risk reduction and uncertainty management. These intelligent techniques can be used for uncertainty analysis, risk assessment, data fusion and mining, data analysis and interpretation, and knowledge discovery, from diverse data such as 3-D seismic, geological data, well logging, and production data. This book is intended for petroleum scientists, data miners, data scientists and professionals and post-graduate students involved in petroleum industry.
