This undergraduate textbook provides a current and comprehensive survey of the sediments and forms generated within Pleistocene and pre-Pleistocene glacial environments. Techniques and methods used in the examination of these sediments and forms are extensively reviewed. This is the most comprehensive and wide-ranging book ever prepared on this topic, and will form the basis for future work in the area. In studying past glacial environments, links are made between understanding modern glaciodynamics, ice physics, and the processes of erosion, transport and deposition of glacial sediments and the generation of various glacial landforms. Past Glacial Environments presents physical geography, earth and environmental science students with an extensive review of the latest research on past glacial environments. The text encompasses Pleistocene subglacial, supraglacial and proglacial sediments and environments, pre-Pleistocene global glacial conditions and sediments, as well as past glacioaeolian, glaciolacustrine, and glaciomarine sediments. Subsequent chapters focus on stratigraphy, lithofacies associations, paleosols, glacio-eustasy and isostasy, micromorphology, SEM, drift prospecting and placer mining.

This book is a comprehensive overview of the ever-captivating field of glaciation from the perspective of glacial landsystems. This approach models the many processes, forms and interactions that can be found in glaciated landscapes throughout the world. Landsystems models allow the glacial geologist and geomorphologist to evaluate these landscapes in relation to the dynamics of glaciation and to climate and geology. Glacial Landsystems brings together the expertise of an international range of specialists to provide an up-to-date summary of landsystems relevant to both modern and ancient glacier systems and also in the reconstruction and interpretation of former glacial environments. The models are applicable at all scales from ice sheets to small valley glaciers. This book is an essential reference for anyone embarking upon research or engineering surveys in glaciated basins and provides a wide-ranging handbook of glacial landsystem types for students of glaciation.

An enlightening investigation of the Pleistocene’s dual character as a geologic time—and as a cultural idea The Pleistocene is the epoch of geologic time closest to our own. It’s a time of ice ages, global migrations, and mass extinctions—of woolly rhinos, mammoths, giant ground sloths, and not least early species of Homo. It’s the world that created ours. But outside that environmental story there exists a parallel narrative that describes how our ideas about the Pleistocene have emerged. This story explains the place of the Pleistocene in shaping intellectual culture, and the role of a rapidly evolving culture in creating the idea of the Pleistocene and in establishing its dimensions. This second story addresses how the epoch, its Earth-shaping events, and its creatures, both those that survived and those that disappeared, helped kindle new sciences and a new origins story as the sciences split from the humanities as a way of looking at the past. Ultimately, it is the story of how the dominant creature to emerge from the frost-and-fire world of the Pleistocene came to understand its place in the scheme of things. A remarkable synthesis of science and history, The Last Lost World describes the world that made our modern one.

The new Second Edition of Glacial Geology provides a modern, comprehensive summary of glacial geology and geomorphology. It is has been thoroughly revised and updated from the original First Edition. This book will appeal to all students interested in the landforms and sediments that make up glacial landscapes. The aim of the book is to outline glacial landforms and sediments and to provide the reader with the tools required to interpret glacial landscapes. It describes how glaciers work and how the processes of glacial erosion and deposition which operate within them are recorded in the glacial landscape. The Second Edition is presented in the same clear and concise format as the First Edition, providing detailed explanations that are not cluttered with unnecessary detail. Additions include a new chapter on Glaciations around the Globe, demonstrating the range of glacial environments present on Earth today and a new chapter on Palaeoglaciology, explaining how glacial landforms and sediments are used in ice-sheet reconstructions. Like the original book, text boxes are used throughout to explain key concepts and to introduce students to case study material from the glacial literature. Newly updated sections on Further Reading are also included at the end of each chapter to point the reader towards key references. The book is illustrated throughout with colour photographs and illustrations.

Iceland provides an unique stage on which to study the natural environment, both past and present, and it is understanding both aspects of reconstructing the past and observing and interpreting the present that form the focus of the contributions to this volume. The papers are all written by active researchers and incorporate both reviews and new data. Although concentrating largely on the recent Quaternary timescale a wide range of topics is explored including subglacial volcanism, onshore and offshore evidence for the Last Glacial Maximum and subsequent deglaciation, current glacial characteristics including jökulhlaups and glacial landsystems, soil development, Holocene ecosystem change, current oceanography, impacts of volcanic sulphur loading, chemical weathering and the CO2 budget and documentary evidence for historical climate. The key element of the volume is that for the first time it provides a wide overview of a range of topics for which Iceland provides an almost unparalleled laboratory emphasizing the importance of research on this small island for studies over a much broader global scale. These reviews point the way to future research directions and are supplemented by extensive illustrations and a comprehensive bibliography. * Wide range of related topics covered both from a present day and quaternary perspective * Reviews from scientists active in each research area across a range of subjects providing both overviews and new data supplemented by an extensive bibliography * Extensive illustrations and examples from the field

Ancient ice ages are revealed by distinctive stratal facies that tell us much about the times of coolness and how the climate system works. Several strong ice ages were recorded in the late Paleozic time and during transitions from the Devonian in to the Carboniferous and from the Ordovician in to the Silurian. In Precambrian time, several are documented for both the late and early Proterozoic age. This title explores findings on the pre-Mesozoic ice ages, examining climate in relation to tectonobiogeochemical activities rooted in the changing earth-air-ocean system.

Sediments are the most valuable form of physical evidence for past Earth surface processes. They have the potential to build up an archive of events and provide a window into the past. Through careful examination of sediments the shifting patterns of surface processes across space and time are revealed, allowing us to reconstruct past environments and environmental change. A Practical Guide to the Study of Glacial Sediments is a guide to the standard techniques employed to read the sedimentary record of former glaciers and ice sheets. It demonstrates that the often complex and fragmentary glacial sedimentary record can, when examined systematically and rationally, provide detailed insights into former environments and climates in places where no other evidence is available. The complementary techniques covered in this book include: facies description, grain size analysis, clast form assessment, clast macrofabric analysis, micromorphology, particle lithology and assessment of engineering properties. They yield consistent and meaningful results in a range of glacial depositional environments throughout the world, from the high Arctic to the Himalayas. A Practical Guide to the Study of Glacial Sediments provides students and researchers with a clear and accessible guide to recording and interpreting glacial successions wherever the location.

This volume contains a selection of papers presented to the Fourth Internation~l Symposium on Environmental Biogeochemistry (ISEB), and a conference on Biogeochemistry in Relation to Mining Industry and Environmental Pollution (Leaching Conference), held in Canberra, Aust ralia on August 26-31 and September 3-4, 1979, respectively. The ISEB were established to provide "a forum for uninhibited exchange of information and ideas among the biological, chemical, atmospheric and geolorical scientists working in the common area of biogeochemistry, encompassing soil and other earth sciences as well as the hydrosphere and atmosphere", By linking the fourth ISEB with the Leachin~ Conference the scope of discussions was extended to encompass the application of biogeochemical processes to the mining industry. This wide-ranging philosophy is reflected in the breadth and diversity of the subjects covered in this book. The published papers are expanded versions of those presented at the meetings. They have all been scrutinized by at least one referee in addition to the editors. About 20% of the contributions to the meetings are not included, either because authors did not wish to publish or because the papers were not accepted by the editors.
