Download or read book Geodynamic Evolution of East Antarctica written by M. Satish-Kumar and published by Geological Society of London. This book was released on 2008 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geological correlations of East Antarctica with adjoining continents have been puzzling geologists ever since the concept of a Gondwana supercontinent surfaced. Despite the paucity of outcrops because of ice cover, difficulty of access and extreme weather, the past 50 years of Japanese Antarctic Research Expeditions (JARE) has successfully revealed vital elements of the geology of East Antarctica. This volume presents reviews and new research from localities across East Antarctica, especially from Dronning Maud Land to Enderby Land, where the geological record preserves a history that spans the Archaean and Proterozoic. The reviews include extensive bibliographies of results obtained by geologists who participated in the JARE. Comprehensive geological, petrological and geochemical studies, form a platform for future research on the formation and dispersion of Rodinia in the Mesoproterozoic and subsequent assembly of Gondwana in the Neoproterozoic to Early Palaeozoic.

Download or read book The Precambrian Earth written by P.G. Eriksson and published by Elsevier. This book was released on 2004-03-04 with total page 967 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the editors strive to cover all primary (i.e. non-applied) topics in Precambrian geology in a non-partisan way, by using a large team of international authors to present their datasets and highly divergent viewpoints. The chapters address: celestial origins of Earth and succeeding extraterrestrial impact events; generation of continental crust and the greenstone-granite debate; the interaction of mantle plumes and plate tectonics over Precambrian time; Precambrian volcanism, emphasising komatiite research; evolution and models for Earth's hydrosphere and atmosphere; evolution of life and its influence on Precambrian ocean chemistry and chemical sedimentation; sedimentation through Precambrian time; the application of sequence stratigraphy to the Precambrian rock record. Each topic is introduced and a non-partisan closing commentary provided at the end of each chapter. The final chapter blends the major geological events and rates at which important processes occurred into a synthesis, which postulates a number of "event clusters" in the Precambrian when significant changes occurred in many natural systems and geological environments.

Download or read book Supercontinent Cycles Through Earth History written by Z.X. Li and published by Geological Society of London. This book was released on 2016-05-20 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Geology of Southwest Gondwana written by Siegfried Siegesmund and published by Springer. This book was released on 2018-02-02 with total page 700 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the geological evolution of Southwest (SW) Gondwana and presents state-of-the-art insights into its evolution. It addresses the diachronic assembly of continental fragments derived from the break-up of the Rodinia supercontinent later amalgamated to build SW Gondwana during the Neoproterozoic–Cambrian transition, which on a global scale includes parts of present-day South America, Africa and Madagascar. The book presents 24 state-of-the-art reviews including the most crucial controversies. Most experienced scientists about the geology of SW Gondwana from Europe, Africa, South America and Australia present contributions on key areas addressing the interactions between the main cratons and fold belts on both sides of the South Atlantic Ocean. Chapters related to the geology of the major Archean- Paleoproterozoic cratons and Neoproterozoic Brasiliano/Pan-African fold belts enable readers to gain an in-depth understanding of the tectonometamorphic and magmatic evolution of SW Gondwana. The book covers a wide range of issues including metallogenetic, sedimentary, paleobiological and paleoclimatic processes and allows a deep insight into this key period of the Earth’s evolution.
Download or read book Crustal Evolution of Southern Africa written by A. J. Tankard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: Syntheses of the geology of major areas of the Earth's crust are increasingly needed in order that the features of, and the problems associated with, the secular evolution of the continents can be understood by a wide audience. Southern Africa is fortunate in having a remarkable variety of geological environments developed without many breaks over 3. 8 Ga, and many of the rock groups are household names throughout the geological world. In one respect the geology of Southern Africa is particularly important: cratonization clearly began as early as 3. 0 Ga ago, in contrast to about 2. 5 Ga in most other continental areas such as North America. This book documents very well the remarkable change in tectonic conditions that took place between the Early and Mid-Precambrian; we have here evidence of the very earliest development of rigid lithospheric plates. This book is a tribute to the multitudes of scientists who have worked out the geology of Southern Africa over many years and decades. Whatever their discipline, each provided a step in the construction of this fascinating story of 3. 8 Ga of crustal development. In the book the reader will find a detailed review of the factual data, together with a balanced account of interpretative models without the indulgence of undue speculation. One of its attractions is its multidisciplinary approach which provides a stimulating challenge to the reader.

The nineteen papers provide a comprehensive review including advanced knowledge and new data from all critical areas of East Gondwana. The recent knowledge of the evolution of East Gondwana, which was regarded as an integral part of the Mesoproterozoic supercontinent Rodinia, is the major theme of the volume, which is reinforced by highlighting this radical and new understanding of the evolution of this region.
Download or read book The History of Geophysics in Southern Africa written by Johan H de Beer and published by AFRICAN SUN MeDIA. This book was released on 2016-01-25 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geophysics is a comparatively young science which only evolved as a distinct discipline during the 19th century. However, its phenomena (like earthquakes, tsunamis, volcanic eruptions and lightning) had been objects of fear, curiosity and speculation since ancient times. In this book, Johan de Beer and his research team reveal that geophysical activity in South Africa can be traced back to as early as 1488. This is a truly astonishing revelation which deserves to be firmly entrenched as part of the country?s proud history. The book also discusses the history and formation of South African geophysical institutions that made a huge and seldom acknowledged contribution to the technological development of southern Africa.

Download or read book Palaeoproterozoic Supercontinents and Global Evolution written by Steven Michael Reddy and published by Geological Society of London. This book was released on 2009 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Palaeoproterozoic era (2500-1600 Ma) is a critical period of Earth history, with dynamic evolution from the deep planetary interior to its surface environment. Several lines of geological evidence suggest the existence of at least one pre-Rodinia supercontinent, named Nuna or Columbia, which formed near the end of Palaeoproterozoic time. Prior to this assembly, there may have been an older supercontinent (Kenorland) or perhaps only independently drifting supercratons. The tectonic records of amalgamation and dispersal of these ancient landmasses provide a framework that links processes of the deep Earth with those of its fluid envelope. The sixteen papers in this volume present reviews and new analytical data that span the geological record of Palaeoproterozoic Earth. The volume is useful as a reference book for students and professional geoscientists interested in this important period of global evolution.
Download or read book Origin and Evolution of the Cape Mountains and Karoo Basin written by Bastien Linol and published by Springer. This book was released on 2016-09-03 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the latest research on the geological, geochemical, geochronological, biological, and geomorphic evolution of the unique and relatively pristine landscape of the Cape Mountains and the Karoo Basin, a region in South Africa that is currently being targeted for shale gas exploration and development. With up-to-date graphics, maps, drill-core and seismic data, it offers the latest observations and synthesis, and highlights areas of ongoing research. The work presented also considers a wider connection of the Cape-Karoo system to other basins in Central Gondwana, including South America, thus following in the footsteps of A. L. du Toit. Clearly, there is still much to be learned before shale gas development can be considered, and this book provides some timely perspectives.
