The fossil history of plant life in Antarctica is central to our understanding of the evolution of vegetation through geological time and also plays a key role in reconstructing past configurations of the continents and associated climatic conditions. This book provides the only detailed overview of the development of Antarctic vegetation from the Devonian period to the present day, presenting Earth scientists with valuable insights into the break up of the ancient supercontinent of Gondwana. Details of specific floras and ecosystems are provided within the context of changing geological, geographical and environmental conditions, alongside comparisons with contemporaneous and modern ecosystems. The authors demonstrate how palaeobotany contributes to our understanding of the palaeoenvironmental changes in the southern hemisphere during this period of Earth history. The book is a complete and up-to-date reference for researchers and students in Antarctic palaeobotany and terrestrial palaeoecology.

Antarctic Paleobiology discusses the current status of paleobiology, principally paleobotany and palynology in Antarctica, and the interrelationship of Antarctic floras to those of other Gondwana continents. It provides a broad coverage of the major groups of plants on the one hand, while on the other seeking to evaluate the vegetational history and the physical and biological parameters that influence the distribution of floras through time and space. The biologic activity is discussed within a framework of the geologic history, including the tectonic and paleogeographic history of the region. Finally, the reader will find a comprehensive bibliography of Gondwana paleobotany and palynology.

No other continent on Earth has undergone such radical environmental changes as Antarctica. In its transition from rich biodiversity to the barren, cold land of blizzards we see today, Antarctica provides a dramatic case study of how subtle changes in continental positioning can affect living communities, and how rapidly catastrophic changes can come about. Antarctica has gone from paradise to polar ice in just a few million years, a geological blink of an eye when we consider the real age of Earth. Frozen in Time presents a comprehensive overview of the fossil record of Antarctica framed within its changing environmental settings, providing a window into a past time and environment on the continent. It reconstructs Antarctica’s evolving animal and plant communities as accurately as the fossil record permits. The story of how fossils were first discovered in Antarctica is a triumph of human endeavour. It continues today with modern expeditions going out to remote sites every year to fill in more of the missing parts of the continent’s great jigsaw of life.

Published by the American Geophysical Union as part of the Special Publications Series. Tectonic, Climatic, and Cryospheric Evolution of the Antarctic Peninsula presents the analysis of data collected during the SHALDRIL program, which sampled the most complete Cenozoic stratigraphic section in the Antarctic Peninsula. The stratigraphic intervals sampled fill major gaps in the existing stratigraphic record in the region, which is believed to have been the last place in Antarctica to become fully glaciated and, as such, the last refugium for plants and animals living on the continent. Providing previously unpublished results from studies aimed at improving our understanding of the changes in climate, glacial setting, and fauna and flora that took place over the past 30 million years, the volume highlights include discussions of marine seismic and drill core records documenting the initial growth and expansion of an ice sheet across the northernmost Antarctic Peninsula continental shelf in the northwestern Weddell Sea. The book features: Detailed vegetation and phytoplankton evolution from greenhouse through icehouse conditions in Antarctica's last refugium Sand grain texture and micromorphology indicating ice sheet control of weathering style Exhumational history around the Drake Passage margins from thermochronology and sediment provenance Comprehensive review of the opening of the ocean passageway between Antarctica and South America and the associated regional tectonics. Tectonic, Climatic, and Cryospheric Evolution of the Antarctic Peninsula will be of interest to geologists, climatologists, and glaciologists interested in climate and cryosphere evolution and those factors that regulate it.

The fourth international symposium on Antarctic Earth Sciences took place in Adelaide, South Australia during the week 16-20 August 1982. This volume contains a record of the centenary activities celebrating Sir Douglas Mawson and the one hundred and seventy-four papers that were presented by delegates for discussion over the five days. Sir Douglas Mawson was part of the first team to reach the magnetic South Pole, a leading geologist and scientific figure during the heroic age of of antarctic exploration. The papers presented during the symposium were divided into fifteen categories covering east and west Antarctica, marine, land and glacial geology, plate tectonics, islands, peninsulas, climatic change and Precambrian and Cenozoic era activity. The two hundred persons from sixteen countries who attended the symposium brought together a wide range of the most current expertise and research to share, of which this volume provides a record.

This book focuses on the Permian time slice in the geological history of Gondwana, which includes Australia, India, South Africa, Antarctica and South America. Coal is an organic rock, the product of compressed and ‘cooked’ plants. The exact formation of coal via physicochemical reactions, burial and subsidence is the subject of numerous books. The vast thick coal deposits characterising Gondwana formed from special kind of trees termed the Glossopteris Flora. These trees shed their leaves in winter and with the rest of their remains decayed and through subsidence and burial formed the coal. Pollen preserved from these plant communities has been concentrated and isolated and is the focus of this book. The first plant communities as can be seen from the pollen graphs in this book were impoverished in species. The Permian era started with a very cold climate and as the climate warmed more and more diverse vegetation took hold. The emergence of different forms of pollen at certain times in the Permian is used as an indicator of climatic change. Furthermore, the predominance of algal spores in some samples and lack of representation by pollen of Glossopteris point to significant changes in the climate which led to the disappearance of their pollen and the accumulation of spores representing algal communities. These climate induced changes are noticed in their completed transformation after a long time span; small changes are evident during a lifetime of Earth’s inhabitants. Today, in our lifetime, we can see and witness the drying of many lakes across the Earth and their total disappearance from maps of only 50 years ago is a testimony to a climatic change taking place. The time of a ‘complete’ change in the Permian is possible to calculate. However, to determine the duration and maximum change in the climate of the earth today is impossible due to the apparent acceleration of the process by industrial activities of our species. Chapter 4 in the book deals with the special characteristics of the Permian coals of Gondwana and the special plant community which made them. The composition of these coals on a microscopic level shows them to be rich in hydrocarbons, more than other coals. The Permian coals of India and Australia generate ‘heavy’ oil which is retained within the coal matrix as bitumen and is a potential source of methane. This chapter demonstrates through a pilot study the potential for explosion in the Permian Gondwana coals through their propensity to spontaneous combustion and methane generation.

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.
