Calder. This book was released on 2019-04-30. Super Continent available in PDF, EPUB and Kindle. A Eurasian transformation is underway, and it flows from China. With a geopolitically central location, the country's domestic and international policies are poised to change the face of global affairs. The Belt and Road Initiative has called attention to a deepening Eurasian continentalism that has, argues Kent Calder, much more significant implications than have yet been recognized. In Super Continent, Calder presents a theoretically guided and empirically grounded explanation for these changes. He shows that key inflection points, beginning with the Four Modernizations and the collapse of the Soviet Union; and culminating in China's response to the Global Financial Crisis and Crimea's annexation, are triggering tectonic shifts. Furthermore, understanding China's emerging regional and global roles involves comprehending two ongoing transformations—within China and across Eurasia as a whole—and that the two are profoundly interrelated. Calder underlines that the geo-economic logic that prevailed across Eurasia before Columbus, and that made the Silk Road a central thoroughfare of world affairs for close to two millennia, is reasserting itself once again.

Download and read online ebook Ancient Supercontinents and the Paleogeography of Earth write by Lauri J. J Pesonen. This book was released on 2021-10-06. Ancient Supercontinents and the Paleogeography of Earth available in PDF, EPUB and Kindle. 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

Download and read online ebook Supercontinent Cycles Through Earth History write by Z.X. Li. This book was released on 2016-05-20. Supercontinent Cycles Through Earth History available in PDF, EPUB and Kindle. 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.
