Geodynamic evolution of East Antarctica : a key to the East-West Gondwana connection

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.Also available:The Boundaries of the West African Craton - ISBN 978-1-86239-251-9West Gondwana: Pre-Cenozoic Correlations Across the South Atlantic Region - ISBN 978-1-86239-247-2Cretaceous-Tertiary High-Latitude Palaeoenvironments: James Ross Basin, Antarctica - ISBN 978-1-86239-197-0The Geological Society of LondonFounded in 1807, the Geological Society of London is the oldest geological society in the world, and one of the largest publishers in the Earth sciences.The Society publishes a wide range of high-quality peer-reviewed titles for academics and professionals working in the geosciences, and enjoys an enviable international reputation for the quality of its work.The many areas in which we publish in include:-Petroleum geology-Tectonics, structural geology and geodynamics-Stratigraphy, sedimentology and paleontology-Volcanology, magmatic studies and geochemistry-Remote sensing-History of geology-Regional geology guides The boundaries of the West African craton, with special reference to the basement of the Moroccan metacratonic Anti-Atlas belt / N.

high-latitude Settings Are Sensitive To Climatically Driven Palaeoenvironmental Change And The Resultant Biotic Response. Climate Change Through The Peak Interval Of Cretaceous Warmth, Late Cretaceous Cooling, Onset And Expansion Of The Antarctic Ice Sheet, And Subsequently The Variability Of Neogene Glaciation, Are All Recorded Within The Sedimentary And Volcanic Successions Exposed Within The James Ross Basin, Antarctica. This Site Provides The Longest Onshore Record Of Cretaceous-tertiary Sedimentary And Volcanic Rocks In Antarctica And Is A Key Reference Section For Cretaceous-tertiary Global Change. The Sedimentary Succession Is Richly Fossiliferous, Yielding Diverse Invertebrate, Vertebrate And Plant Fossil Assemblages, Allowing The Reconstruction Of Both Terrestrial And Marine Systems. The Papers Within This Volume Provide An Overview Of Recent Advances In The Understanding Of Palaeoenvironmental Change Spanning The Mid-cretaceous To The Neogene Of The James Ross Basin And Related Biotic Change, And Will Be Of Interest To Many Working On Cretaceous And Tertiary Palaeoenvironmental Change.
