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.

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.

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.

The Early Palaeozoic was a critical interval in the evolution of marine life on our planet. Through a window of some 120 million years, the Cambrian Explosion, Great Ordovician Biodiversification Event, End Ordovician Extinction and the subsequent Silurian Recovery established a steep trajectory of increasing marine biodiversity that started in the Late Proterozoic and continued into the Devonian. Biogeography is a key property of virtually all organisms; their distributional ranges, mapped out on a mosaic of changing palaeogeography, have played important roles in modulating the diversity and evolution of marine life. This Memoir first introduces the content, some of the concepts involved in describing and interpreting palaeobiogeography, and the changing Early Palaeozoic geography is illustrated through a series of time slices. The subsequent 26 chapters, compiled by some 130 authors from over 20 countries, describe and analyse distributional and in many cases diversity data for all the major biotic groups plotted on current palaeogeographic maps. Nearly a quarter of a century after the publication of the ‘Green Book’ (Geological Society, London, Memoir12, edited by McKerrow and Scotese), improved stratigraphic and taxonomic data together with more accurate, digitized palaeogeographic maps, have confirmed the central role of palaeobiogeography in understanding the evolution of Early Palaeozoic ecosystems and their biotas.

Understanding Earth's Deep Past

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.

Ancient Landscapes of Western North America

Pages : 228 pages

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.

How are mountains formed? Why are there old and young mountains? Why do the shapes of South America and Africa fit so well together? Why is the Pacific surrounded by a ring of volcanoes and earthquake prone areas while the edges of the Atlantic are relatively peaceful? Frisch and Meschede and Blakey answer all these questions and more through the presentation and explanation of the geo-dynamic processes upon which the theory of continental drift is based and which have lead to the concept of plate tectonics.

Antarctica preserves a rock record that spans three and a half billion years of history and has a remarkable story to tell about the evolution of our Earth, from the hottest crustal rocks yet found in an orogenic system, to the assembly and breakup of Gondwana in the Phanerozoic. This volume highlights our improved understanding of the tectonic events that have shaped Antarctica and how these potentially relate to supercontinent assembly and fragmentation. The internal constitution of the East Antarctic Shield is assessed using information available from the basement geology and from detritus preserved as Mesozoic sediments in the Trans Antarctic Mountains. Accretionary orogenesis along the proto-Pacific margin of Antarctica is examined and the volumes of intracrustal melting compared with juvenile magma additions in these complex orogenic systems assessed. This special volume demonstrates the diversity of approaches required to elucidate and understand crustal evolution and evaluate the supercontinent concept.
