Book Description
Complexing and Hydrothermal Ore Deposition provides a synthesis of fact, theory, and interpretative speculation on hydrothermal ore-forming solutions. This book summarizes information and theory of the internal chemistry of aqueous electrolyte solutions accumulated in previous years. The scope of the discussion is limited to those aspects of particular interest to the geologist working on the problem of hydrothermal ore genesis. Wherever feasible, fundamental principles are reviewed. Portions of this text are devoted to calculations of specific hydrothermal equilibriums in multicomponent solutions at elevated temperatures, including a general examination and evaluation of the solution chemistry and geochemical parameters involved in aqueous transport and deposition of the ore-forming metals. This publication is intended for geologists, but is also beneficial for students conducting research on the components of soil and rock.

Book Description
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.

Book Description
Volume 65 of Reviews in Mineralogy and Geochemistry attempts to fill this gap and to explicitly focus on the role that co-existing fluids play in the diverse geologic environments. It brings together the previously somewhat detached literature on fluid–fluid interactions in continental, volcanic, submarine and subduction zone environments. It emphasizes that fluid mixing and unmixing are widespread processes that may occur in all geologic environments of the entire crust and upper mantle. Despite different P-T conditions, the fundamental processes are analogous in the different settings.

Book Description
This book addresses the origin of gold deposits to answer questions of science and curiosity. These answers contribute in turn to the improved exploration and mining of gold. Initially there is a summary of the methods used to address the genesis of gold deposits including some of the essential science and concepts. Five basic observations follow that apply to many gold deposits and need to be considered in any genetic ideas. Magmatic processes enriching gold are discussed followed by the role of aqueous fluids during gold deposit formation at elevated temperatures and pressures. Modifying effects after deposit formation include high-grade metamorphism, retrogression, weathering, and erosion. The main types of gold deposits are then explained within the spectrum of viable genetic ideas, with informal names for these examples that include gold-only, gold-plus, Carlin, slate-belt, epithermal, porphyry, iron oxide copper gold, and Archean greenstone. Case histories are included in which the role of gold geology contributed directly to discoveries—one example is at the province-scale and another at the goldfield-scale. Unlike other books on the subject, this one addresses virtually all gold deposit types rather than focusing on one type in isolation. The primary readership includes industry geologists, senior undergraduates, postgraduates, and those with some knowledge of science and an interest in the gold industry.

Book Description
Classifications and Historical Studies is a collection of papers dealing with theoretical and applied ore petrology. One paper discusses the use of conceptual models in geology such as the diagrammatic/pictorial, the flow-chart, and the tabular types of conceptualizations. Another paper describes some transitional types of mineral deposits in volcanic and sedimentary rocks. Concentrations of copper minerals and commonly associated metals form deposits associated with orogenic belts and cratonic regions. The paper points out that many major groups of mineral deposits grade into other groups through occurrences with intermediate or transitional characteristics. It suggests a classification method of mineral deposits based on the observable features of the mineral deposits rather than their inferred genesis. One paper reviews the theory of magmatic—hydrothermal replacement origin of stratiform sulfide ore bodies. The review covers concepts of certain major ore deposits as being independent and isolated phenomena to regarding a wide range of deposits as contemporaneous, indigenous, and related to their environments. Another paper points out that according to North American geologists, certain types of ore deposits are formed syngenetically and are subjected to the same metamorphic events that affect the ores in which they are enclosed. The collection can be valuable to researchers, technical designers, or engineers whose works are related with oil refinery and fossil fuels, as well as to students majoring in geology.
