Book Description
The Australide orogen, the southern hemisphere Neoproterozoic to Mesozoic terrane accretionary orogen that forms the palaeo-Pacific margin of Gondwana, is one of the largest and longest-lived orogens on Earth. This book brings together a series of reviews and multidisciplinary research papers that comprehensively cover the Australides from the Tasman orogen of eastern Australia to the Neoproterozoic and Palaeozoic orogens of South America, taking in New Zealand and Antarctica along the way. It deals with the evolution of the southern Gondwana margin, as it grew during a series of terrane accretion episodes from the late Proterozoic through to final fragmentation in mid-Cretaceous times. Global perspectives are given by comparison with the Palaeozoic northern Gondwana margin and documentation of world-wide terrane accretion episodes in the Late Triassic-Early Jurassic and mid-Cretaceous. The Tasmanides of eastern Australia, and the terrane histories of New Zealand and southern South America are given comprehensive up-to-date reviews.

Book Description
This volume summarizes the current state of knowledge of each of the main sectors of the basin. After reconstructing Permian-Triassic Gondwanaland, authors from South America, South Africa, Antarctica, and Australia illustrate the relevant geology of each sector in maps and time-space diagrams under

Book Description
Gondwana, comprising more than 64% of the present day continental mass, is home to 33% of large igneous provinces (LIPs) and key to understanding the lithosphere–atmosphere system and related tectonics that influenced global climate and sediment production on Earth. Gondwana has many of the largest LIPs, with areas of 200 000 to 2 000 000 km2. Several Gondwana LIPs erupted near active continental margins as well as within continents. The rifting of continents continued even after LIP emplacement or was aborted by a coeval compression and did not open into an ocean. Important contemporary frontiers include understanding significant amounts of synchronous silicic volcanic rocks in mafic LIPs, bringing better stratigraphic constraints supported by precise age dating and volume estimation of LIPs, the possible link between LIP emplacement and biotic crisis, refinement of the existing petrogenetic models and assessing large eruptions and associated societal risk. This volume covers topics on magma emplacements, petrology and geochemistry, source characteristics, flood basalt–carbonatite linkage, tectonics and geochronology of LIPs distributed in Gondwana continents.

Book Description
This volume focuses on Late Mesoproterozoic to early Cambrian events related to Gondwana assembly and break up. 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.

Book Description
This book presents a summary of the geology of the Transantarctic Mountains for Earth scientists who may want to work there or who need an overview of the geologic history of this region. In addition, the properties of the East Antarctic ice sheet and of the meteorites that accumulate on its surface are treated in separate chapters. The presentation ends with the Cenozoic glaciation of the Transantarctic Mountains including the limnology and geochemical evolution of the saline lakes in the ice-free valleys. • The subject matter in this book is presented in chronological order starting about 750 million years ago and continuing to the present time. • The chapters can be read selectively because the introduction to each chapter identifies the context that gives relevance to the subject matter to be discussed. • The text is richly illustrated with 330 original line drawings as well as with 182 color maps and photographs. • The book contains indexes of both subject matter and of authors’ names that allow it to be used as an encyclopedia of the Transantarctic Mountains and of the East Antarctic ice sheet. • Most of the chapters are supplemented by Appendices containing data tables, additional explanations of certain phenomena (e.g., the formation and seasonal destruction of stratospheric ozone), and illustrative calculations (e.g., 38Cl dates of meteorites). • The authors have spent a combined total of fourteen field seasons between 1964 and 1995 doing geological research in the Transantarctic Mountains with logistical support by the US Antarctic Program. • Although Antarctica is remote and inaccessible, tens of thousands of scientists of many nationalities and their assistants have worked there and even larger numbers of investigators will work there in the future.
