This book explores the geotectonic evolution of the lithosphere beneath the Indian Shield, which comprises a collage of cratons variously bounded by mobile belts and palaeo-rifts. The lithosphere beneath these is fairly thin compared to other cratons worldwide, petrologically varied and shows considerable variation in thickness with depth both intra-craton and among cratons. Moreover, it has been subjected to the influence of repeated magmatic episodes from Proterozoic to Palaeocene, which have variously impacted different parts of the shield. The thermotectonic influence on constituent cratons is variable depending on the evolutionary history. This book discusses the impact of successive tectonomagmatic events on the evolution of the deep crust and shallow mantle, and their Phanerozoic modification as gleaned through the xenolith window. The book provides a petrotectonic perspective on the deep crust and shallow mantle from direct samples brought up as xenoliths of deep lithologies, and offers a comprehensive overview for students, researchers, academics and professionals, integrating the results of petrological studies of deep lithologies and geophysical investigations to (i) shed light on the physico-chemical and thermal structure of the lithosphere from an array of geotectonic settings and (ii) gain insights into the spatio-temporal evolution of the Indian Shield. An in-depth guide critical thinking on the complex issue of mantle differentiation, magmatism, lithosphere modification and crustal growth over time, the book allows readers to gain a better understanding of the processes that affect the lithosphere and shape the crust on which we live.

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.

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 Metallogeny of Lode Gold Deposits: A Syngenetic Perspective is a synthesis of lode gold vein forming processes, addressing the commonality in similar worldwide deposits. The book's empirical model incorporates widely known and accepted principles of ore deposition and shows how it applies in the volcanic-sedimentary greenstone belt environment. Several chapters detail outcrop maps and photos of field occurrences and textures. The interpretations flow directly from the authors' field work, and are coupled with analyses of underlying physical processes. Utilizing detailed geological mapping, field work, and chemical analyses as the basis of a syngenetic formation mode, the text arms readers with the tools necessary to accurately analyze and interpret new data on the subject. This includes information on decoding the significance of asymmetry in vein formation, as well as the role of lamprophyres in gold camps, how Archean geology requires integration into a lode vein formation model, and how to develop an understanding of the worldwide applicability of gold cycles to lode vein formation and exploration and how it can be applied to deposits of all ages.

Environmental Impact of Mining and Mineral Processing: Management, Monitoring, and Auditing Strategies covers all the aspects related to mining and the environment, including environmental assessment at the early planning stages, environmental management during mine operation, and the identification of major impacts.

This book presents essential data on the geology of the Puchezh-Katunki crater - an early Jurassic crater located on the East European Platform, with an impact structure that is ca. 80 km in diameter. Offering a comprehensive guide, it reviews the studies carried out during the last several decades on this prominent but not well-known impact structure. It offers the international community state-of-the-art information on the crater with regard to e.g. structural mapping, drilling (including the Vorotilovo well, which is 5374 m deep), geophysical research, and the petrological analysis of impactites and various breccias. In addition, the book includes new results from the mineralization and crystallizations beneath this large impact crater, and suggests new models for crater formations.

Tight gas reservoirs have very low permeability and porosity, which cannot be produced at economical flow rates unless the well is efficiently stimulated and completed using advanced and optimized technologies. Economical production on the basis of tight gas reservoirs is challenging in general, not only due to their very low permeability but also to several different forms of formation damage that can occur during drilling, completion, stimulation, and production operations.

This study demonstrates in detail the effects of different well and reservoir static and dynamic parameters that influence damage mechanisms and well productivity in tight gas reservoirs. Geomechanics, petrophysics, production and reservoir engineering expertise for reservoir characterization is combined with a reservoir simulation approach and core analysis experiments to understand the optimum strategy for tight gas development, delivering improved well productivity and gas recovery.

This book presents the first compilation of scientific research on the island of Nisyros, involving various geoscientific disciplines. Presenting a wealth of illustrations and maps, including a geological map of the volcano, it also provides valuable insights into the geothermal potential of Greece. The island of Nisyros is a Quaternary volcano located at the easternmost end of the South Aegean Volcanic Arc. The island is nearly circular, with an average diameter of 8 km, and covers an area of approximately 42 km2. It lies above a base of Mesozoic limestone and a thin crust, with the mantle-crust transition located at a depth of approximately 27 km. The volcanic edifice of Nisyros comprises a succession of calc-alkaline lavas and pyroclastic rocks, as well as a summit caldera with an average diameter of 4 km. Nisyros marks the most recent volcano in the large prehistoric volcanic field between Kos-Yali-Strongyli-Pyrgousa-Pachia-Nisyros, where the largest eruption ("Kos Plateau Tuff") in the history of the eastern Mediterranean devastated the Dodecanese islands 161,000 years ago. Although the last volcanic activity on Nisyros dates back at least 20,000 to 25,000 years, it encompasses an active hydrothermal system underneath the volcano with temperatures of roughly 100 DegreesC at the Lakki plain, the present-day caldera floor and 350 DegreesC at a depth of 1,550 m. A high level of seismic unrest, thermal waters and fumarolic gases bear testament to its continuous activity, which is due to a large volume of hot rocks and magma batches at greater depths, between 3,000 and 8,000 m. Violent hydrothermal eruptions accompanied by major earthquakes occurred in 1873 and 1888 and left behind large, "world-wide unique" explosion craters in the old caldera. Through diffuse soil degassing, the discharge of all hydrothermal craters in the Lakki plain releases 68 tons of hydrothermal-volcanic derived CO2 and 42 MW of thermal energy per day. This unique volcanic and hydrothermal environment is visited daily by hundreds of tourists.

Thomas Gold (1920-2004) had a curious mind that liked to solve problems. He was one of the most remarkable astrophysicists in the second half of the twentieth century, and he attracted controversy throughout his career. Based on a full-length autobiography left behind by Thomas Gold, this book was edited by the astrophysicist and historian of science, Simon Mitton (University of Cambridge).

The book is a retrospective on Gold's remarkable life. He fled from Vienna in 1933, eventually settling in England and completing an engineering degree at Trinity College in Cambridge. During the war, he worked on naval radar research alongside Fred Hoyle and Hermann Bondi - which, in an unlikely chain of events, eventually led to his working with them on steady-state cosmology. In 1968, shortly after their discovery, he provided the explanation of pulsars as rotating neutron stars.

In his final position at Cornell, he and his colleagues persuaded the US Defense Department to fund the conversion of the giant radio telescope at Arecibo in Puerto Rico into a superb instrument for radio astronomy. Gold's interests covered physiology, astronomy, cosmology, geophysics, and engineering.

Written in an intriguing style and with an equally intriguing foreword by Freeman Dyson, this book constitutes an important historical document, made accessible to all those interested in the history of science.

Emerald-green hiddenite, a gem so valuable that it is said "a June bug can carry away $1,000 worth," is only found in one area of North America: Alexander County, North Carolina. Now known as the village of Hiddenite, the area has continuously produced gems of great beauty since 1875, including the largest natural emerald and the largest faceted emerald in North America. The beauty of the area's free-standing minerals of emerald green beryl and spodumene, as well as amethyst, smoky quartz, calcite, and rutile have attracted collectors, adventurers, and miners since their discovery. The search for emeralds and other gemstones over more than 100 years has generated true drama: controversies about mineral names, who discovered what, tragic fatal accidents, and physical strife between individuals. This book reveals the whole story. Alongside the fascinating history of the area, it includes detailed information about the geology of the region, and will be of interest to the historian, mineral enthusiast, and the curious reader alike.

This book investigates the mineralogy and shock effects of Yanzhuang chondrite, using modern micro-mineralogical experimental techniques, including SEM, TEM, EPMA, Raman microprobe spectroscopy, instrumental neutron activation analysis, X-ray micro-diffraction analysis, micro-PIXE analysis and laser ablation ICP-MS. The micro-structural and micro-morphological characteristics as well as chemical composition of minerals were studied in details. Based on the studies in the shock effects of rocks and minerals, and the detailed study in the shock-produced melt, the book concludes that Yanzhuang chondrite is the most heavily shocked ordinary H group chondrite ever found and that it contains the most abundant shock induced melt among all known shock-melt-bearing chondritic meteorites.

"Polymineral-Metasomatic Crystallogenesis" is dedicated to the foundations of polymineral crystallogenesis in solutions typically occurring in nature. Effects, laws, and mechanisms of a metasomatic crystal replacement, joint crystal growth of different phases, mixed crystal formation, and aggregate re-crystallization as well as oriented overgrowth (epitaxy and quasi-epitaxy) and crystal habit origin are considered experimentally. The behaviour of these processes in nature are discussed in addition to pseudomorphs, poikilitic crystals (and other replacement forms), features of rapakivi structure, fluorite morphology, and many more. The concept is a generalization of the classic theory on crystallogenesis which is complicated by phase interaction in polymineral systems.

"Polymineral-Metasomatic Crystallogenesis" is designed for chemists, geologists, physicists, and postgraduates and advanced undergraduate students of these fields.

"Uncovers a centuries-long story of obsession that often included murder, gun fights, deadly accidents, overnight fortunes and even cannibalism. . . Neligh is a practiced writer whose style mixes history and modern realities seamlessly." -Colorado Country Life Gold! brings together the story of this metal’s glittering legacy in the Centennial State and the madness, murder, and mayhem that came along with it. The book examines the rich history of the miners and treasure hunters who came to face danger and hardships in the unforgiving Rocky Mountains. This story is unique in that it takes a look at the phenomenon of gold, the treasure hunters, both modern and historic, and brings them to life in a detailed and sharp narrative. Author Ian Neligh spent a year meeting with experts and enthusiasts, hearing their stories and trying to understand why it is they continue to do what they do—often in the face of extreme hardship. Modern-day gold miners profiled include Al Mosch, Bill Chapman, Ken Reid, and Chad Watkins. Gold! is the story of an unusual subculture on the rise in the mountains of Colorado fueled by a delicate balance of hope, greed, and loss. It tells the story of men mostly forgotten by the world as they go in endless pursuit of an impossible fortune. It follows miners working their small, dangerous gold claims in mines over a hundred years old, to modern-day prospectors trying to strike it rich and counterbalance the weight of a struggling economy. The book also examines if those who spend their lives in search of riches—ever actually strike it rich. This book will appeal to both history buffs as well as fans of modern-day reality shows like Gold Rush.

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."

1. PURPOSE OF PRESENT BOOK During the period May 19-26, 2003 the NATO Advanced Research Workshop (ARW) "Mud volcanism, Geodynamics and Seismicity" was held in Baku. Participants coming from USA, Germany, France, Italy, Portugal, Russian Federation, Ukraine, Romania, Georgia, UK, Israel, Azerbaijan, Tunisia have discussed about different geodynamic features of mud volcanism and participated to field trips oriented to a better knowledge of mud volcanic features. The Meeting focused on many features of mud volcanism occurrence and related geodynamic topics. The purpose of present book is to collect contributions discussed during the Meeting and to fill a marked editorial gap on mud volcanism. Mud volcanism was to date described by local monographies or by articles published by scientific journals. In particular no books were published on topics able to highlight the link among mud volcanism, geodynamics and seismicity. Mud volcano of Nirano (Northern Italy). Engraving from Stoppani A. (1871), Corso di Geologia, Milan, Bernardoni G. and Brigola G. Publishers. 2. WHY MUD VOLCANOES ARE GEOLOGICALLY IMPORTANT ? Mud volcanoes have attracted the attention of earth scientists for many years. Due to their importance in hydrocarbon research, a consistent progress in the knowledge of mud volcanism took place in the past twenty years. Mud extrusion is a well-known phenomenon occurring in geological environments where fluid-rich, fine grained sediments ascend within a lithologic succession due to their buoyancy.

With an approach that stresses the fundamental solid state behaviour of minerals, and with emphasis on both theory and experiment, this text surveys the physics and chemistry of earth materials. It starts with a systematic tour of crystal chemistry of both simple and complex structures (with completely new structural drawings) and discusses how structural and thermodynamic information is obtained experimentally. The quantitative concepts of chemical bonding band theory, molecular orbit and ionic models are reviewed. The book goes on to discuss physical properties and to relate microscopic features to macroscopic thermodynamic behaviour. The book then discusses high pressure phase transitions, amorphous materials and solid state reactions, and concludes with a look at the interface between mineral physics and materials science. Highly illustrated throughout, this book is designed to fill the gap between undergraduate texts and specialized review volumes, for students in earth sciences and materials science.

The book provides a unique blending of different content on observational and critical aspects of data acquisition, geological, structural, tectonic set-up, mineral deposit types, geophysical framework, and proximity indicator minerals. Combining these topics led to a comprehensive understanding to facilitate mineral targeting and exploration in green- and brown-field terrains. Besides field photographs, the write-up is lavishly supplemented with relevant geological and geophysical maps, tables, and case stories in field geology, making it useful for a much larger section of the geoscientific community professional geologists and geophysicists, students, teachers, and also decision-makers in geo-surveys and exploration.

The book summarizes the results of the experimental studies of phase relations in the chemical systems relevant to Earth, carried out by the author in a time period of over 20 years between 1979 and 2001. It is based on 1000 piston-cylinder experiments at pressures up to 4 GPa, and close to 700 experiments carried out with a multi-anvil apparatus at pressures up to 24 GPA. This is the largest published collection of calculated phase diagrams for the chemical systems relevant to Earth. This is also the first time that the phase relations at the relatively low pressures of the lithospheric mantle, mainly applicable to the experimental thermobarometry of metamorphic rocks and mantle xenoliths, are seamlessly integrated with the phase relations of the sublithospheric upper mantle and the uppermost lower mantle, primarily applicable to inclusions in diamond and schocked meteorites. "Tibor Gasparik has devoted his career to determining the high-pressure, high-temperature phase relations of the geologically important Sodium-Calcium-Magnesium-Aluminium-Silicon (NCMAS) oxide system. This book is his opus magnum, summarizing more than 1700 experiments in over 120 figures. ... I have found Phase Diagrams for Geoscientists to be a useful first port-of-call for finding the P-T stability fields ... and I can recommend the book as a reference for geoscientists requiring an overview of the stable phase assemblages in the top 700 km of the Earth." (David Dobson, Geological Magazine, Vol. 142 (2), 2005)
