Modern Approaches in Solid Earth Sciences – serie

Modern seismology has faced new challenges in the study of earthquakes and their physical characteristics. This volume is dedicated to the use of new approaches and presents a state of the art in historical seismology. Selected historical and recent earthquakes are chosen to document and constrain related seismic parameters using updated methodologies in the macroseismic analysis, field observations of damage distribution and tectonic effects, and modelling of seismic waveforms. A critical re-evaluation of historical accounts and early seismograms provides us with the basis for a realistic seismic hazard assessment. This book is dedicated to the memory of Jean Vogt (1929 - 2005).Audience: This book is of value to seismologists, earthquake geologists, engineering seismologists, earth scientists and historians of catastrophes.

Microbial activities influence water-rock interaction processes and chemical transport between the major geochemical reservoirs and the formation/transformation of minerals and rocks, whereas geological processes and geochemical controls influence the microbial ecology in extreme environments. How biological activity influences geological processes and what role these processes played in the geological evolution of the Earth are fundamental questions. How do we recognize the ancient microbial activities in the rock record and what analytical methods do we use to document them to better understand the evolution of life? Can we detect the existence of microbial life in deep time by studying Archaean rocks? Microbial systems in extreme environments and in the deep biosphere may be analogous to potential life on other planetary bodies and hence may be used to investigate the possibilities of extraterrestrial life.This book explores these questions in an interdisciplinary approach, and examines the mode and nature of links between geological processes and microbial activities and their significance for the origin and evolution of life on the Earth and possibly on other planets.

This book furnishes detailed information about Turkey's existing mineral resources, besides providing concepts and ideas which may help the search for potential mineral resources in the future. It is a first book in the English-language international literature on mineral resources of Turkey and it is aimed at economic geologists, mining engineers, and mining investors, as well as graduate and undergraduate students. This work focuses mainly on  a range of mineral systems and related geological features throughout Turkey. Taking into account the lack of international literature on these resources, a considerable portion of the book explains the geological context of the region and the settings in which the mineral resources occur. The genetic characteristics of these mineral resources are emphasized and important information is also presented on their economic aspects. All chapter contributions are prepared by researchers and professional geologists.

This book describes for the first time the complexity of the Northeastern Transbaikalia province of Russia. This province is one of the largest Early Proterozoic metallogenic provinces on Earth. It comprises three extra large deposits: Cu-sandstones Udokan, Fe-Ti-V and Cu-PGE Chiney, and REE Katugin. This book is a research study and includes geological, mineralogical, and geochemical data obtained by the authors from 30 field trips in the region, using XRF, ICP-MS, La-ICP-MS, EPMA, and the study of Sr, Nd, U-Pb isotopes in rocks and minerals. It demonstrates the complicated origin of Cu deposits comprising 50 Mt copper concentrated in sedimentary and magmatic rocks in this area.

This book presents a comprehensive overview of Australian impact structures and related mineralization, including a discussion of the significance of many of these structures for crustal evolution. The book  focuses in particular on Archaean impact ejecta/fallout units in the Pilbara Craton of Western Australia, large exposed and buried impact structures, and on the geophysical evidence for possible to probable impact structures. Thanks to their long-term geological stability, Precambrian and younger terrains in the Australian continent contain 38 confirmed impact structures and 43 ring and dome structures, many of which constitute possible to probable asteroid impact structures. The impact structures have been the subject of more than half a century of studies and range from several tens of meter-large craters to buried structures larger than 100 km in diameter. Discoveries of impact fallout units in the Pilbara Craton have defined the Pilbara as one of the two best documented terrains where Archaean impact ejecta/fallout deposits are identified, the other terrain being the Kaapvaal Craton in southern Africa. A synthesis of evidence from both cratons indicates periods of large asteroid bombardments during ~3.47 – 2.48 billion years-ago, including peak bombardment about 3.25—3.22 billion years-ago. The latter period coincides with an abrupt transformation of an early Archaean granite-greenstone crust to mid to late Archaean semi-continental crustal regimes, underpinning the significance of heavy asteroid impact events for crustal evolution. Apart from proven impact structures, Australian terrains display a range of circular features, including morphological and drainage rings, circular lakes, volcanic craters, tectonic domes, oval granite bodies, mafic igneous plugs, salt diapirs, and magnetic, gravity and seismic anomalies, many of which are of a likely impact origin. Thermal and hydrothermal processes associated with impact cratering bearimportant consequences for the formation of mineral deposits, such as Ni at Sudbury, Pb-Zn at Siljan and Kentland. Impact structures may also provide sites for the accumulation of hydrocarbons, whereas in some instances fracturing associated with impact structures allows outward migration of oil and gas.

This book examines existing mineral fiscal policies covering income taxation, royalties, free carried and participative (community and government) interests and also highlights the impacts of these policies on the feasibility of mineral projects as well as on revenue and other benefits to the State. While publications already exist on the subject matter, they have invariably approached the topic primarily from a Government standpoint rather than the mining industry. This book aims to provide a balance in this debate by comparing the financial outcomes gained or foregone by both Government and industry under different policy regimes. The discussions are supported by quantitative examples to more clearly articulate the potential outcomes and better inform future fiscal policy decisions.

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.

One of today’s major geoscientific controversies centres on the origin of the Archean granite‒greenstone terranes. Is the geology of these scattered remnants of our planet’s early crust consistent with the theory that modern-style plate-tectonic processes operated from the early Archean, or does it indicate that tectonic and magmatic processes were different in the Archean? Earth has clearly evolved since its initial formation, so at what stage did its processes of crustal growth first resemble those of today? The logical place to seek answers to these intriguing and important questions is within the best-preserved early Archean crust.The Pilbara region of northwest Australia is internationally famous for its abundant and exceptionally well-preserved fossil evidence of early life. However, until recently the area has received much less recognition for the key evidence it provides on early Archean crustal evolution. This book presents and interprets this evidence through a new stage-by-stage account of the development of the Pilbara’s geological record between 3.53 and 2.63 Ga.The Archean Pilbara crust represents one fragment of Earth’s oldest known supercontinent Vaalbara, which also included the Kaapvaal Craton of southern Africa. Recognition of Vaalbara expands the background database for both these areas, allowing us to more fully understand each of them.

This book provides a comprehensive overview of mineral resource targeting and assessment based on the mineral systems approach. It presents prediction and evaluation methods for six major types of mineral systems—magmatic, magmatic hydrothermal, volcanic, strata‑bound endogenic, sedimentary, and sedimentary metamorphic—each illustrated with case studies from China, offering practical guidance for researchers and practitioners in teaching, resource prediction, and assessment.The book opens with fundamental theories and methods for regional metallogenic analysis and quantitative mineral potential assessment, together with integrated information evaluation workflows. It then addresses critical technologies, including geological formation analysis, geophysical and geochemical data processing and interpretation, remote sensing applications, and quantitative prediction techniques. Dedicated chapters subsequently detail the classification, prediction models, and evaluation procedures for each of the six mineral system types, all supported by regional‑scale application examples.A key feature is a database of 25 major mineral systems occurring in China, built upon multiple GIS layers comprising 1:200,000‑scale geological, geochemical, and geophysical maps and remote sensing imagery. These data are the outcome of a nationwide survey conducted in China from 2006 to 2013, whose primary objective was to define criteria for country‑scale assessment and targeting of mineral resources.

Archaean terrains contain a wealth of structural, stratigraphic, textural, mineralogical, geochemical and isotopic features allowing insights into the nature of the early Earth. This book is based on studies during 1964-2007 of Archaean terrains in Australia and to a lesser extent in South Africa and India, as well as on visits to Archaean terrains in Canada, the US and China, as well as petrological and geochemical studies of igneous and sedimentary rock suites from a range of terrains. The book will include a range of photographic and microscopic images, geological sketch maps and diagrams illustrating the lessons derived from field and the laboratory. Also other Archaean terrains are being reviewed.The book is intended for Earth scientists as well as broader intelligent readership.

This book will broaden readers’ understanding of pegmatites in a special geodynamic setting, dealing with the emplacement of the Hagendorf-Pleystein Pegmatite Province (HPPP) in the Central European Variscides. This treatise illustrates the complex processes leading to the formation and partial destruction of the pegmatites, documenting the geochronological, chemical, mineralogical, geological and geomorphological / sedimentological data set. The book starts with a detailed account of the economic geology of the various pegmatites, explaining why these deposits are a major resource of ceramic raw materials. In its concluding section, a model of the pegmatite evolution in an ensialic orogen provides meaningful insights into the genetic aspects of pegmatite generation.The Late Paleozoic rare-element pegmatites of the HPPP, Oberpfalz-SE, Germany, rank among the largest concentrations in Europe. The biggest pegmatite of this mining district totals 4.4 million tons of ore (Hagendorf-South). The mining history of the HPPP is restricted to the 20th century, when local entrepreneurs started mining operations in search of ceramic raw materials, feldspar and quartz. Today the “Silbergrube Aplite” is still worked for feldspar. The traditional mining of pegmatitic and aplitic rocks in Central Europe, such as the Bohemian Massif, which is shared by Germany, the Czech Republic, Poland and Austria, has been focused on these industrial minerals. In addition to these major commodities, lithium was mined for a period of time. But even today many of these pegmatites of calc-alkaline affiliation have not lost their appeal to mineralogists and mineral enthusiasts for their wealth of minerals that contain P, Nb, Ta, Li, Be, B, U, Th, Sc, Ti and Sn. The most favorable crustal section to bring about pegmatitic rocks of this type, encompassing pegmatoids, metapegmatites, reactivated pseudopegmatites and pegmatites sensu stricto is the ensialic orogen,exemplified by the Variscan (Hercynian) Orogen, which geodynamically connects the Paleozoic pegmatite provinces in North America and Europe. The geological history of the HPPP, however, goes much further than the Carboniferous-Permian magmatic activity, when the last structural disturbances of the Variscan orogeny affected the NE-Bavarian Basement between 450 and 330 Ma. During this time mafic magmatic rocks together with calcareous and arenaceous sediments were converted into paragneisses, calcsilicate rocks, and amphibolites. It is the period of time when tectonic shortening led to over thrusting and when the emplacement of nappes and the architectural elements of the ensialic orogen began taking shape. During the Late Permian, the Mesozoic and the Cenozoic, the HPPP did not lie idle in geological terms; hypogene and supergene alteration continued and found its most recent expression in alluvial-fluvial “nigrine” placer deposits, which resulted from the unroofing of the pegmatites and aplites in the HPPP and can be used even outside HPPP as an ore guide to pegmatites.

The book outlines principal milestones in the evolution of the atmosphere, oceans and biosphere during the last 4 million years in relation with the evolution from primates to the genus Homo – which uniquely mastered the ignition and transfer of fire. The advent of land plants since about 420 million years ago ensued in flammable carbon-rich biosphere interfaced with an oxygen-rich atmosphere. Born on a flammable Earth surface, under increasingly unstable climates descending from the warmer Pliocene into the deepest ice ages of the Pleistocene, human survival depended on both—biological adaptations and cultural evolution, mastering fire as a necessity. This allowed the genus to increase entropy in nature by orders of magnitude. Gathered around camp fires during long nights for hundreds of thousandth of years, captivated by the flickering life-like dance of the flames, humans developed imagination, insights, cravings, fears, premonitions of death and thereby aspiration for immortality, omniscience, omnipotence and the concept of god. Inherent in pantheism was the reverence of the Earth, its rocks and its living creatures, contrasted by the subsequent rise of monotheistic sky-god creeds which regard Earth as but a corridor to heaven. Once the climate stabilized in the early Holocene, since about ~7000 years-ago production of excess food by Neolithic civilization along the Great River Valleys has allowed human imagination and dreams to express themselves through the construction of monuments to immortality. Further to burning large part of the forests, the discovery of combustion and exhumation of carbon from the Earth’s hundreds of millions of years-old fossil biospheres set the stage for an anthropogenic oxidation event, affecting an abrupt shift in state of the atmosphere-ocean-cryosphere system. The consequent ongoing extinction equals the past five great mass extinctions of species—constituting a geological event horizon in the history of planetEarth.

This book by Vietnamese and Russian authors is the first of its kind and combines the extensive knowledge on the petrology and metallogeny of the late Paleozoic – early Mesozoic and Cenozoic periods in North Vietnam. The Permian – Triassic and Paleogene volcano-plutonic and plutonic associations are two important geological events in the evolutionary history of Southeast Asia, including the 260 – 250 Ma Emeishan mantle plume and Indian-Eurasia collision at 60 – 55 M.The volume includes 9 chapters,  divided into 3 parts. Part 1 introduces the geological structure of North Vietnam; Part 2 covers the Permian – Triassic magma associations and metallogeny; and Part 3 focuses on  the Cenozoic magma associations and metallogeny.In each chapter, the geological setting of magmas, classification of different geological structures, and  composition characteristics, such as mineralogy, geochemistry, isotope systematics and geochronology are discussed.  This  book represents an important reference document for international and Vietnamese geologists engaged in the geological  history and metallogeny of Vietnam, an important area  of the Asian continent. The monograph also has a practical significance in contributing new premises and  to assess rare and precious mineral prospects. In addition, it can be regarded as a necessary data base for petrological and metallogenic projects and university courses.

This book provides a detailed overview of the operational principles of modern mining geology, which are presented as a good mix of theory and practice, allowing use by a broad range of specialists, from students to lecturers and experienced geologists.The book includes comprehensive descriptions of mining geology techniques, including conventional methods and new approaches. The attributes presented in the book can be used as a reference and as a guide by mining industry specialists developing mining projects and for optimizing mining geology procedures. Applications of the methods are explained using case studies and are facilitated by the computer scripts added to the book as Electronic Supplementary Material.

This book presents projections and blueprints of the future geologic period, climate and biosphere, based on our current understanding of the Earth’s history and recent developments in the atmosphere-ocean-cryosphere system.By the second decade of the 21st century it has become clear that, rather than channel its efforts into protecting its planetary biosphere and living species, Homo sapiens continues to sink its remaining resources into weapons, including nuclear missiles – thus increasing the risk of intentional or accidental spread of radioactive nuclides on land, oceans and atmosphere.With time, possibility becomes probability, and probability becomes certainty ‒ heralding a transition from the Anthropocene to a new geological period, named here as Plutocene after the element Plutonium. During the Plutocene the biosphere is dominated by elevated temperatures, analogous to the Pliocene (2.6 – 5.3 Ma ago) or the Miocene (5.3 - 23 Ma ago) when mean global temperatures were 2 to 4 degrees Celsius warmer and sea levels 20 to 40 meters higher than pre-industrial levels. High levels of radioactivity will persist for at least 20,000 years and acid oceans will severely limit biological activity to the hardiest species. Atmospheric CO2 higher than 500 ppm with residence time on the order of thousands of years will delay the subsequent glacial cycle.These factors restrict comparisons of the Plutocene with biosphere conditions during the Miocene and Pliocene periods, partly because the flora and fauna evolved more gradually during these periods, unlike the abrupt climate shift of state during the second half of the 20th century and first part of the 21st century. Following a long lull in biological activity dominated by radiation-resistant organisms, especially Arthropods, a resumption of glacial cycles and decline in radioactivity will lead to the re-emergence of descendants of burrowing mammals and other genera. Depending on the intensity of radioactive pollution, hunter-gatherer humans may survive in northern latitudes, relatively cold high-altitude mountain valleys and elevated volcanic islands. In some areas subsistence farming may be possible. A new cycle will commence.

Modern seismology has faced new challenges in the study of earthquakes and their physical characteristics. This volume is dedicated to the use of new approaches and presents a state of the art in historical seismology. Selected historical and recent earthquakes are chosen to document and constrain related seismic parameters using updated methodologies in the macroseismic analysis, field observations of damage distribution and tectonic effects, and modelling of seismic waveforms. A critical re-evaluation of historical accounts and early seismograms provides us with the basis for a realistic seismic hazard assessment. This book is dedicated to the memory of Jean Vogt (1929 - 2005).Audience: This book is of value to seismologists, earthquake geologists, engineering seismologists, earth scientists and historians of catastrophes.

Microbial activities influence water-rock interaction processes and chemical transport between the major geochemical reservoirs and the formation/transformation of minerals and rocks, whereas geological processes and geochemical controls influence the microbial ecology in extreme environments. How biological activity influences geological processes and what role these processes played in the geological evolution of the Earth are fundamental questions. How do we recognize the ancient microbial activities in the rock record and what analytical methods do we use to document them to better understand the evolution of life? Can we detect the existence of microbial life in deep time by studying Archaean rocks? Microbial systems in extreme environments and in the deep biosphere may be analogous to potential life on other planetary bodies and hence may be used to investigate the possibilities of extraterrestrial life.This book explores these questions in an interdisciplinary approach, and examines the mode and nature of links between geological processes and microbial activities and their significance for the origin and evolution of life on the Earth and possibly on other planets.

Accretionary prisms in convergent margins are natural laboratories for exploring initial orogenic processes and mountain building episodes.  They are also an important component of continental growth both vertically and laterally. Accretionary prisms are seismically highly active and their internal deformation via megathrusting and out-of-sequence faulting are a big concern for earthquake and tsunami damage in many coastal cities around the Pacific Rim. The geometries and structures of modern accretionary prisms have been well imaged seismically and through deep drilling projects of the Ocean Drilling Program (and recently IODP) during the last 15 years. Better understanding of the spatial distribution and temporal progression of accretionary prism deformation, structural and hydrologic evolution of the décollement zone (tectonic interface between the subducting slab and the upper plate), chemical gradients and fluid flow paths within accretionary prisms, contrasting stratigraphic and deformational framework along-strike in accretionary prisms, and the distribution and ecosystems of biological communities in accretionary prism settings is most important in interpreting the evolution of ancient complex sedimentary terrains and orogenic belts in terms of subduction-related processes.  This book is a collection of interdisciplinary papers documenting the geological, geophysical, geochemical, and paleontological features of modern accretionay prisms and trenches in the northwestern Pacific Ocean, based on many submersible dive cruises, ODP drilling projects, and geophysical surveys during the last 10 years. It also includes several papers presenting the results of systematic integrated studies of recent to ancient on-land accretionary prisms in comparison to modern analogues.  The individual chapters are data and image rich, providing a major resource of information and knowledge from these critical components of convergent margins forresearchers, faculty members, and graduate and undergraduate students.  As such, the book will be a major and unique contribution in the broad fields of global tectonics, geodynamics, marine geology and geophysics, and structural geology and sedimentology.

Better understanding of the spatial distribution and temporal progression of accretionary prism deformation, structural and hydrologic evolution of the décollement zone (tectonic interface between the subducting slab and the upper plate), chemical gradients and fluid flow paths within accretionary prisms, contrasting stratigraphic and deformational framework along-strike in accretionary prisms, and the distribution and ecosystems of biological communities in accretionary prism settings is most important in interpreting the evolution of ancient complex sedimentary terrains and orogenic belts in terms of subduction-related processes.  This book is a collection of interdisciplinary papers documenting the geological, geophysical, geochemical, and paleontological features of modern accretionay prisms and trenches in the northwestern Pacific Ocean, based on many submersible dive cruises, ODP drilling projects, and geophysical surveys during the last 10 years. It also includes several papers presenting the results of systematic integrated studies of recent to ancient on-land accretionary prisms in comparison to modern analogues.  The individual chapters are data and image rich, providing a major resource of information and knowledge from these critical components of convergent margins forresearchers, faculty members, and graduate and undergraduate students.  As such, the book will be a major and unique contribution in the broad fields of global tectonics, geodynamics, marine geology and geophysics, and structural geology and sedimentology.

The basis of this investigation is the petrographic and geochemical understanding of principal igneous rock types of the Noril’sk region, in order to demonstrate that these data provide unique and self-evident solutions to the problems of petrogenesis and mineralization. The results of the investigations are presented in two volumes: the first includes mainly text and the second contains illustrations.In the first volume, the state of the main problems of the genesis of igneous rocks with reference to Traps and related ore deposits is discussed, as well as short petrological descriptions of igneous complexes in the region, the mineral and geochemical diversity of the rocks, and aspects of the differentiation of basaltic melts and mineralization are described. Taking into account the vast number of publications on the petrology of Traps of the Noril’sk region, primary attention in the monograph is given to earlier unknown phenomena, as well as other aspects that are of great importance for solving genetic problems. Some exotic geologic targets such as the Mikchandinsky differentiated cover, the magnetite lava flow of the Putorana Plateau, the magmatogenic breccia of Kharaelakh and others are described in detail.The second volume contains an atlas of Rock Indications of igneous rock-types; formally identified reference rocks from all igneous complexes of the region, as well as photographs of thin sections of typical rocks and analytical tables of rocks and minerals from the key sections of sedimentary units and intrusions. Each rock type has been geochemically and petrographically analysed thereby providing a formal identity, complete with a photograph of the thin section.Photomicrographs of the rocks in this book will be a useful aid in visualizing the diversity of rock types in the Traps; each photograph reflecting a unique combination of minerals.
