DOWNLOAD EBOOKProfessor Richard (Rick) Sibson revolutionized structural geology by illustrating that fault rocks contain an integrated record of earthquakes. Fault-rock textures develop in response to geological and physical variables such as composition, environmental conditions (e.g. temperature and pressure), fluid presence and strain rate. These parameters also determine the rate- and state-variable frictional stability of a fault, the dominant mineral deformation mechanism and shear strength, and ultimately control the partitioning between seismic and aseismic deformation. This volume contains a collection of papers that address the geological record of earthquake faulting from field-based or theoretical perspectives.
Supercontinent Cycles Through Earth History

DOWNLOAD EBOOKThe supercontinent-cycle hypothesis attributes planetary-scale episodic tectonic events to an intrinsic self-organizing mode of mantle convection, governed by the buoyancy of continental lithosphere that resists subduction during the closure of old ocean basins, and the consequent reorganization of mantle convection cells leading to the opening of new ocean basins. Characteristic timescales of the cycle are typically 500 to 700 million years. Proposed spatial patterns of cyclicity range from hemispheric (introversion) to antipodal (extroversion), to precisely between those end members (orthoversion). Advances in our understanding can arise from theoretical or numerical modelling, primary data acquisition relevant to continental reconstructions, and spatiotemporal correlations between plate kinematics, geodynamic events and palaeoenvironmental history. The palaeogeographic record of supercontinental tectonics on Earth is still under development. The contributions in this Special Publication provide snapshots in time of these investigations and indicate that Earth’s palaeogeographic record incorporates elements of all three end-member spatial patterns.

DOWNLOAD EBOOKPrinciples of Precambrian Geologyis an update to the 1991 book, Precambrian Geology: The Dynamic Evolution of the Continental Crust, by the same author. The new edition covers the same topics in a more concise and accessible format and is replete with explanatory figures, tables, and illustrations. The book serves as a modern comprehensive statement on the Earth's Precambrian crust, covering the main aspects of distribution, lithiostratigraphy, age, and petrogenesis of Precambrian rocks by continent within the context of the Earth's evolving continental crust. Principles of Precambrian Geology provides a suitable framework for assessing various Earth dynamic and biospheric hypotheses, including the modern plate tectonic paradigm and the Gaian hypothesis. Despite the concise format, the new edition provides extensive updated references to support the information presented. It is designed to serve the needs of student, teacher, explorationist and general student of the continental crust. - Updated to provide more concise accessible information - Extensive illustrations, tabulations, and maps - Provides a framework for assessing recent hypothesis on Earth dynamics - Covers main aspects of distribution, lithostratigraphy, age, and protogenesis of Precambrian rocks
Sediment Hosted Lead-Zinc Sulphide Deposits

DOWNLOAD EBOOKThe Deposit Modeling Program was founded by UNESCO-IUGS with the major aim to disseminate knowledge from scientists in more developed countries to their counterparts from less developed ones. A fringe benefit of this effort was the compilation of information on existing models and promotion of topical workshops in developing countries. This book is the result of one such workshop that took place in Delhi and Udaipur, India, in December 2001. Sediment-hosted Lead-Zinc Sulphide Deposits compiles the work of renowned economic geologists from three continents. The authors highlight the recent advances in the understanding of the temporal and tectono-stratigraphic distribution of sediment-hosted Pb-Zn sulphide ores and processes governing their genesis. The first section comprises five chapters covering some of the most important deposits of this class in Australia and Canada in detail, emphasizing their genetic models. It also includes a paper on the "geoenvironmental model," which concerns behavior before mining and resulting from mining, processing, and smelting. The second section discusses the mineralized terranes in the state of Rajasthan, northwest India, which host three major sulphide deposits. This reference is packed with color and black and white photographs, illustrations, charts, and graphs, making it a valuable, up-to-date resource for any geologist or geotechnical scientist studying major mineral deposits.
Tectonic Controls and Signatures in Sedimentary Successions

DOWNLOAD EBOOKStratigraphers and sedimentologists who are presently describing and interpreting the infill of sedimentary basins are generally agreed that it is difficult to disentangle the signatures of tectonic processes from those of climate and eustatic sea level change in the resultant rock succession. Until better criteria are developed to distinguish between the roles played by the major variables, it is still most useful to document and interpret basin-fill architectures where we know, from independent evidence, that one of the main controls is likely to have been a major contributor. This book contains a collection of papers describing situations where the tectonic setting is fairly well established, and it can be assumed that at least the tectonic factor has contributed to the resultant signatures.

DOWNLOAD EBOOKThis book demonstrates the direct link between petroleum, the derivative of organic materials, and ore bodies. The studies reported here highlight the common factors between hydrocarbons and mineral concentrations, such as heat sources, migration routes and likely traps. It emphasizes the role that hydrothermal processes play in the genesis of both petroleum generation and ore-grade mineralization. The presence of oil residue in the form of bitumen and pyrobitumen in all sediment-hosted ore bodies throughout the geological record is a testimony to their common diagenetic history. Studies of active hydrothermal systems reported in this book describe the processes and derivatives in these environments, linking hydrocarbon generation and mineral precipitation. A comparison with residual oil in many ore bodies and mineralization occurrences in the geological record, as depicted in this book, can be explained in terms of processes in active hydrothermal systems. One of the most interesting and challenging recent discoveries, that of living nano-bacteria, is reported in this book. The `nanobes', as they have recently been dubbed, have been suggested as the link between the living and non-living matter. The resemblance of these nano-organisms to fossil forms observed in a Martian meteorite have been reported recently in the media. Likewise the similarity to nano-bacteria in Archaean sediments is highlighted in two chapters of the book.

DOWNLOAD EBOOKEconomically viable concentrations of mineral resources are uncommon in Earth’s crust. Most ore deposits that were mined in the past or are currently being extracted were found at or near Earth’s surface, often serendipitously. To meet the future demand for mineral resources, exploration success hinges on identifying targets at depth. Achieving this requires accurate and informed models of the Earth's crust that are consistent with all available geological, geochemical and geophysical information, paired with an understanding of how ore-forming systems relate to Earth’s evolving structure. Contributions to this volume address the future resources challenge by (i) applying advanced microscale geochemical detection and characterization methods, (ii) introducing more rigorous 3D Earth models, (iii) exploring critical behaviour and coupled processes, (iv) evaluating the role of geodynamic and tectonic setting and (v) applying 3D structural models to characterize specific ore-forming systems.
