Book Description
Progress in Precambrian geology has been exceptionally great, indeed quite striking for geologists of the older generation; only some 30-40 years ago the Precambrian appeared as an uncertain and even mystic prelude to geologic evolution. Even the very name - Precambrian - means some indi visible unit in the early history of the Earth, the beginning of which is poorly known. At the same time it was obvious that the Precambrian formations are of extremely varied and complex composition and poor knowledge and lack of reliable methods of division and correlation were to blame for the lack of significant progress in studies of this early evolutionary stage of the planet. Certainly, even at the very start of Precambrian studies, the results obtained were quite promising, lifting as they did the mysterious veil over the regional Precambrian; but they presented no general realistic picture of this early stage in the Earth's evolution at that time. Recently, this situation has completely changed, due to new methods of study of the older forma tions, and due also to the refinement of some well-known methods, in particular of division, dating, and correlation of "silent" metamorphic strata. Application of different isotope methods of dating was most impor tant in providing objective rock age and thereby the age of geologic events recorded in these rocks. Thus it became possible to reconstruct the oldest geologic period of our planet.

Book Description
This book presents findings from research into the Precambrian history of the Indian shield obtained using state-of-the-art technology. It demonstrates a paradigm shift towards studying the Precambrian shield regions using petrological, geochemical, structural, metallogenic, sedimentological and paleobiological data from the rocks in the Precambrian shield area, and presents a collection of contributions on these diverse topics that help to reconstruct the Precambrian evolution of the Indian Shield.

Book Description
A valuable resource for geologists, engineers, and students across multiple disciplines, this is the most comprehensive and in-depth study of the development of the Baltic Shield, its features as a representative of other similar areas around the world, and the implications for practical applications, such as oil and ore production. Like Sorokhtin's most recent book, The Origins of Natural Diamonds, also available from Wiley-Scrivener at www.wiley.com, this is not just the story of the origin and evolution of the Baltic Shield, but a story about the evolution of the Earth's geology in general. Important to geologists, geophysicists, and engineers across multiple disciplines, written by experts on the Earth's geological evolution, this volume represents the state-of-the-art in major Earth geological processes. Of particular importance to mining engineers and petroleum engineers, it is also a practical guide for those who work in the mining or petroleum industry. Before presenting the most in-depth discussion of the Baltic Shield available and its implications for study by geologists and various industries such as the petroleum industry, the authors present a theory for how the Earth, as we know it, came into existence and developed. They base this theory on scientific evidence and mathematical models, using this as a basis for further explanation of the Earth's geological evolution. Valuable as either a learning tool for the student or as a reference or refresher for the veteran scientist or engineer, the authors explain important geological processes, such as the Earth's origin, composition, and structure, the Earth's energy balance, continental drift, tectonic activity, the evolution of the Earth's crust, and others. It is within this geological framework that the authors offer practical guidance for engineers and scientists who work in industry or academia. It is a must-have for any geologist, geophysicist, or engineer working in mining or petroleum engineering.

Book Description
Ancient Supercontinents and the Paleogeography of Earth offers a systematic examination of Precambrian cratons and supercontinents. Through detailed maps of drift histories and paleogeography of each continent, this book examines topics related to Earth's tectonic evolution prior to Pangea, including plate kinematics, orogenic development, and paleoenvironments. Additionally, this book discusses the methodologies used, principally paleomagnetism and tectonostratigraphy, and addresses geophysical topics of mantle dynamics and geodynamo evolution over billions of years. Structured clearly with consistent coverage for Precambrian cratons, this book combines state-of-the-art paleomagnetic and geochronologic data to reconstruct the paleogeography of the Earth in the context of major climatic events such as global glaciations. It is an ideal, up-to-date reference for geoscientists and geographers looking for answers to questions surrounding the tectonic evolution of Earth. - Provides robust paleogeographies of Precambrian cratons based on high-quality paleomagnetic and geochronologic data and critically tested by global geological datasets - Includes links to updated databases for the Precambrian such as PALEOMAGIA and the Global Paleomagnetic Database (GPMDB) - Presents full-color maps of the drift histories of each continent as well as their paleogeographies - Discusses key questions regarding continental drift, the supercontinent cycle, and the geomagnetic dipole hypothesis and analyzes palaeography in the context of Earth's holistic evolution

Book Description
This Memoir provides a comprehensive review of the Precambrian basins of the four Archaean nuclei of India (Dharwar, Bastar, Singhbhum and Aravalli-Bundelkhand), encompassing descriptions of the time-space distribution of sedimentary-volcanic successions, the interrelationship between tectonics and sedimentation, and basin histories. Studies of 22 basins within the framework of an international basin classification scheme deepen an understanding of the basin architecture especially for cratonic basins. Most Indian sedimentary successions formed as cratonic to extensional-margin rift and thermal-sag basins, some reflecting mantle plume movement, subcrustal heating or far-field stress. This Memoir shows that Phanerozoic plate-tectonic and sequence stratigraphic principles can be applied to the Precambrian basins of large Archaean provinces. The differences between the stratigraphic architecture of the Indian Precambrian and examples of Phanerozoic basin-fill successions elsewhere are ascribed to variable rates and intensities of the controls on accommodation and sediment supply, and changes inherent in the evolution of the hydrosphere-atmosphere and biosphere systems.

Book Description
The mountains and fjords of Greenland preserve a record of nearly four billion years of Earth history -- a story of mountain building, volcanic eruptions, primitive life and ice ages. During this vast period of time, through processes of continental drift, Greenland has journeyed from the southern hemisphere through the tropics to its present polar position. This volume presents an account of the geological evolution of Greenland, together with its mineral wealth and hydrocarbon potential. It is written in a form that is aimed at the general reader with an interest in the dramatic history of our planet.
