Ancient Supercontinents and the Paleogeography of the Earth offers a systematic examination of the cratons of the Precambrian and the supercontinent cycle. Through detailed maps of drift histories and paleogeography of each continent, the book addresses questions about Earth's evolution, such as whether continental drift took place before Pangea, what was the drift velocity of the ancient continents, whether the continents collided, and whether Earth had supercontinents before Pangea. Additionally, the book will cover the methodologies used, and will apply those methodologies to testing the dipole hypothesis. Structured clearly with consistent coverage for all cratons, Ancient Supercontinents and the Paleogeography of the Earth combines state-of-the-art paleomagnetic and radiometric data to reconstruct the paleogeography of the Precambrian Earth in the context of major ancient events, such as global glaciations, and summarize apparent polar wander paths (APWPs) of the continents. It is an ideal, up-to-date reference for geoscientists and geographers looking for answers to questions surrounding the continental evolution of Earth. Provides robust paleogeographies of Precambrian cratons based on high-quality paleomagnetic and radiometric data and critically tested by global geological datasets Includes links to updated databases for the Precambrian such as PALEOMAGIA and other geological databases 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 dipole hypothesis and analyze palaeography in the context of Earth's past events

The 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.

The shifting continents of the Earth are heading for inevitable collision: 250 million years from now, all the land masses on this planet will come together in a single, gigantic supercontinent which no human is ever likely to see. That future supercontinent will not be the first to form on Earth, nor will it be the last. Each cycle lasts half a billion years, making it the grandest of all the patterns in nature. It is scarcely a century since science first understood how Pangaea, the supercontinent which gave birth to dinosaurs, split apart, but scientists can now look back three-quarters of a billion years into the Earth's almost indecipherable past to reconstruct Pangaea's predecessor, and computer-model the shape of the Earth's far-distant future. Ted Nield's book tells the astounding story of how that science emerged (often in the face of fierce opposition), and how scientists today are using the most modern techniques to draw information out of the oldest rocks on Earth. It also reveals the remarkable human story of the Altantis-seeking visionaries and madmen who have been imagining lost or undiscovered continents for centuries. Ultimately all supercontinents exist only in the human imagination, but understanding the 'Supercontinent Cycle' represents nothing less than finally knowing how our planet works.

Frontiers in Earth Science is an open-access journal that aims to bring together and publish on a single platform the best research dedicated to our planet. This platform hosts all the rapidly growing and continuously expanding domains in Earth Science, involving the lithosphere (including geology, geophysics, geochemistry, and geography), the hydrosphere (including hydrology and cryospheric, marine and ocean sciences, complementing the existing Frontiers journal on Marine Science) and the atmosphere (including meteorology and climatology). As such, Frontiers in Earth Science focuses on the countless processes operating within and among the major spheres constituting our planet. In turn, the understanding of these processes provides the theoretical background to better use the available resources and to face the major environmental challenges (including earthquakes, tsunamis, eruptions, floods, landslides, climate changes, sea level rise, extreme meteorological events): this is where interdependent processes meet, requiring a holistic view to better live on and with our planet. Within this volume are included the Grand Challenge papers for the Earth Science field, authored by the Field Chief Editor, and several of the 16 online specialty sections, authored by the respective Chief Editors. These articles identify and describe the crucial challenges for Earth Science at the dawn of the 21st century.

Proterozoic Orogens of India: A Critical Window to Gondwana provides a unique opportunity to understand a cross-section of the well-exposed and best-studied part of Earth’s crust and the processes of continental collision. It covers pulses of reworking processes and their impact on magmatism, metamorphism and deformational history of Proterozoic orogens vis-à-vis the supercontinental formation. The details of structural architecture, crustal blocks, shear zone systems, magmatism, metamorphism, geochemical and isotopic signatures, mineralization and tectonic models of all the Proterozoic orogens of India are discussed along with excellent illustrations reflecting the field-based, multi-scale structural and geological data sets. The spatial distribution, geometry, kinematics and transpressional strain of the shear zone systems (mostly suture zones), which are critical to all conceptual models dealing with tectono-metamorphic history of Proterozoic orogens of India, are also covered. The book summarizes and integrates the state-of -the art understanding of the structural architecture, lithological assemblages, petrological, geochemical, geochronological and geophysical aspects of the Proterozoic orogens of India. Includes a much needed state-of-the-art tectonic summary of the voluminous data that has emerged from the Protrozoic orogens of India in the last 2-3 decades Authored by a well-established expert with more than 30 years of experience in the field based, multi-scale structural geological studies of the ancient orogens of India Covers up-to-date reviews and models of Proterozoic orogens developed in the Indian shield over the past 2.5 billion years of Earth history

There is little dispute within the scientific community that humans are changing Earth's climate on a decadal to century time-scale. By the end of this century, without a reduction in emissions, atmospheric CO2 is projected to increase to levels that Earth has not experienced for more than 30 million years. As greenhouse gas emissions propel Earth toward a warmer climate state, an improved understanding of climate dynamics in warm environments is needed to inform public policy decisions. In Understanding Earth's Deep Past, the National Research Council reports that rocks and sediments that are millions of years old hold clues to how the Earth's future climate would respond in an environment with high levels of atmospheric greenhouse gases. Understanding Earth's Deep Past provides an assessment of both the demonstrated and underdeveloped potential of the deep-time geologic record to inform us about the dynamics of the global climate system. The report describes past climate changes, and discusses potential impacts of high levels of atmospheric greenhouse gases on regional climates, water resources, marine and terrestrial ecosystems, and the cycling of life-sustaining elements. While revealing gaps in scientific knowledge of past climate states, the report highlights a range of high priority research issues with potential for major advances in the scientific understanding of climate processes. This proposed integrated, deep-time climate research program would study how climate responded over Earth's different climate states, examine how climate responds to increased atmospheric carbon dioxide and other greenhouse gases, and clarify the processes that lead to anomalously warm polar and tropical regions and the impact on marine and terrestrial life. In addition to outlining a research agenda, Understanding Earth's Deep Past proposes an implementation strategy that will be an invaluable resource to decision-makers in the field, as well as the research community, advocacy organizations, government agencies, and college professors and students.

Allow yourself to be taken back into deep geologic time when strange creatures roamed the Earth and Western North America looked completely unlike the modern landscape. Volcanic islands stretched from Mexico to Alaska, most of the Pacific Rim didn’t exist yet, at least not as widespread dry land; terranes drifted from across the Pacific to dock on Western Americas’ shores creating mountains and more volcanic activity. Landscapes were transposed north or south by thousands of kilometers along huge fault systems. Follow these events through paleogeographic maps that look like satellite views of ancient Earth. Accompanying text takes the reader into the science behind these maps and the geologic history that they portray. The maps and text unfold the complex geologic history of the region as never seen before.
