Chemical Analysis of Silicate Rocks is the sixth book in the series, “Methods in Geochemistry and Geophysics.” This book provides procedures in chemical analysis of the principal types of silicate rocks and minerals, and it discusses each procedure at length. The book presents different apparatuses and reagents, such as balance and weighs, glassware and porcelain, platinum and substitutes, and filters that are used in the chemical analysis of silicate rocks. Laboratory instruments, such as pH meters, spectrophotometers and flame photometers, are presented in the third chapter. The fourth chapter focuses on the major factors in spectrophotometric methods. The next three chapters cover the common operations in silicate analysis, chemical analysis of silicate rocks, and preparation of the laboratory sample. From chapter eight through 20, each chapter discusses various silicate rocks and minerals, and presents the methods to be used for their chemical analysis. These chemical components are silicon, total iron, titanium, aluminum, calcium, magnesium, ferrous iron, manganese, chromium, alkalies, water and carbon dioxide, phosphorus, and total sulfur. Chapters 21 and 22 offer the formulas of minerals and the determination of specific gravity. The book closes by providing notes on the precision and accuracy of results obtained in silicate rock.

Atomic Absorption Spectrometry in Geology, Second Edition, aims to introduce geologists to the basic simplicity and applicability of atomic absorption spectrometry as it relates to geologic problems; to provide a summary of applications of atomic absorption to geology that are at scattered throughout the literature; and to encourage the accelerated application of atomic absorption spectrometry to geological problems. The book is organized into two parts. The first part, ""Theory and instrumentation,"" explains the theory of atomic absorption spectrophotometry; the operation of the atomic absorption spectrophotometer; and the types of interferences in atomic absorption spectrometry. The second part, ""Methods and applications,"" deals with applications of the atomic absorption method, including detection of the metal content of natural waters; metallic content of ores; and the analysis of trace elements in rocks and minerals. Also discussed are applications of the atomic absorption method in marine geochemistry and for isotopic abundance studies. The book includes some Appendices to the First Edition.

Conceptual Models in Exploration Geochemistry: The Canadian Cordillera and Canadian Shield is a compilation of 38 case histories from the shield and the cordillera. This volume aims to develop models ideally for the systematic description and exploration of geochemical data. These idealized models describe the principles and mechanisms of anomalies, which govern the use of exploration geochemistry. Furthermore, this volume focuses on the use of soils and sediments in exploration geochemistry. This volume is divided into four sections, the first of which is an introduction about landscape geochemistry, the idealized models, standardization of field data, and the general principles of geochemical migration. The second section consists of the idealized models and nineteen case studies obtained from the Canadian Cordillera. The third section also consists of idealized models and case studies but these were obtained from the Canadian Shield. Both the second and third sections discuss, in different views, the mineral zoning and distribution of mineralization, Pleistocene geology, physiography, climate and vegetation, and soils. This volume concludes with a discussion on orientation sampling and standardization of data collection and presentation.

Methods in Geochemistry and Geophysics 11: Geochemical Facies Analysis summarizes research regarding geochemical analysis of sedimentary facies. It demonstrates the extent to which geochemical criteria can be used to interpret sedimentary facies and considers the physicochemical criteria that affect the sediments deposited, including salinity, temperature, and redox potential. It also examines element or isotope variations in sedimentary rocks that are associated with variations in the depositional environment. Organized into seven chapters, this volume begins by defining the facies. It also presents the prerequisites of geochemical facies analysis. This includes the permanence of the composition of the oceans through long periods of the Earth's history, along with climatic, tectonic, and biological influences. The book then discusses methodological prerequisites for the determination of geochemical facies. It provides the results of geochemical facies analyses, including those for hydrofacies, lithofacies, and biofacies. In addition, it explains the non-chemical methods of facies analysis. The book concludes by looking at practical applications and future importance of geochemical facies analysis. This is an invaluable source book for students, geochemists, and geophysicists.

W-Sn Skarn Deposits

Intended as a reference for the academically-oriented geologist as well as the practising economic geologist, this book is concerned with the study of skarn deposits having anomalously high tin or tungsten contents, or both. Unlike many other books on economic geology, both economic W-Sn skarns and non-economic examples are covered, in order to enable the academically-oriented reader to grasp the full range of such deposits, and also to aid the economic geologist in distinguishing between W-Sn skarns having economic potential and those which do not.W-Sn skarns are notoriously complex, containing a wide range of textures, grain sizes, mineral assemblages, bulk compositions and structures. The lack of a sufficiently detailed data base, coupled with some unsupportable genetic models, has led to many misunderstandings and has often resulted in needless expenditure and effort on fruitless mineral exploration. Thus, the first aim of this book is simply to provide an adequate data base with sufficient references to enable an interested worker to define a skarn deposit and know where to find additional information on similar examples. To aid this, as much data as possible is presented as tables and diagrams.The second aim of the book is to show the reader how to separate skarn rocks found in W-Sn-bearing environments into those produced by metamorphic, isochemical processes (metamorphic skarns) which are uneconomic, and those produced by the introduction and exchange of components from an ore solution (ore skarn). W-Sn skarns are also separated into genetically logical subdivisions so that, if a deposit or a specific geological environment can be identified, then skarn zonation or the potential of finding specific skarn types can be predicted. This is particularly important to the practising exploration geologist because often only a small part of a skarn or only certain skarn types contain economic mineralization.In addition, the book provides an insight into how to assess where mineralogical complications may occur, especially with respect to Sn-skarns, and in which environments such complications may be expected. It also provides enough information for the reader to be able to conceptualize suitable models for W-Sn skarns based on primary data.

New Perspectives on Deep-water Sandstones

This handbook is vital for understanding the origin of deep-water sandstones, emphasizing sandy-mass transport deposits (SMTDs) and bottom-current reworked sands (BCRSs) in petroleum reservoirs. This cutting-edge perspective, a pragmatic alternative to the conventional turbidite concepts, is crucial because the turbidite paradigm is built on a dubious foundation without empirical data on sandy turbidity currents in modern oceans. In the absence of evidence for sandy turbidity currents in natural environments, elegant theoretical models and experimental observations of turbidity currents are irrelevant substitutes for explaining the origin of sandy deposits as "turbidites." In documenting modern and ancient SMTDs (sandy slides, sandy slumps, and sandy debrites) and BCRSs (deposits of thermohaline [contour] currents, wind-driven currents, and tidal currents), the author describes and interprets core and outcrop (1:20 to 1:50 scale) from 35 case studies worldwide (which include 32 petroleum reservoirs), totaling more than 10,000 m in cumulative thickness, carried out during the past 36 years (1974-2010). The book dispels myths about the importance of sea level lowstand and provides much-needed clarity on the triggering of sediment failures by earthquakes, meteorite impacts, tsunamis, and cyclones with implications for the distribution of deep-water sandstone petroleum reservoirs.

Significant refinements of biogeochemical methods applied to mineral exploration have been made during more than twenty years since the last major publication on this technique. This innovative, practical and comprehensive text is designed as a field handbook and an office reference volume. It outlines the historical development of biogeochemical methods applied to mineral exploration, and provides details of what, how, why and when to collect samples from all major climatic environments with examples from around the world. Recent commercialization of sophisticated analytical technology permits immensely more insight into the multi-element composition of plants. In particular, precise determination of ultra-trace levels of ‘pathfinder’ elements in dry tissues and recognition of element distribution patterns with respect to concealed mineralization. Data handling and interpretation are discussed in context of a wealth of previously unpublished information, including a section on plant mineralogy, much of which has been classified as confidential until recently. Data are provided on the biogeochemistry of more than 60 elements and, by case history examples, their roles discussed in assisting in the discovery of concealed mineral deposits. A look to the future includes the potential role of bacteria to provide new focus for mineral exploration. Analyses of samples from the controlled environment of Britain’s Eden Project are presented on an accompanying CD as part of a database that includes, also, the potential role of the halogens to assist in mineral exploration. Data on this CD provide a ‘hands-on’ approach for the reader to interrogate and personally assess real datasets from the burgeoning discipline of biogeochemical exploration.
