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.

Provides the first comprehensive review of the current state of the science on tills It is critical that glacial scientists continue to refine their interpretations of ancient archives of subglacial processes, specifically those represented by tills and associated deposits, as they form the most widespread and accessible record of processes at the ice-bed interface. Unfortunately, despite a long history of investigation and a lexicon of process-based nomenclature, glacial sedimentologists have yet to reach a consensus on diagnostic criteria for identifying till genesis in the geological record. What should be called till? Based on the author’s extensive field research, as well as the latest literature on the subject, this book attempts to provide a definitive answer to that question. It critically reviews the global till literature and experimental and laboratory-based assessments of subglacial processes, as well as the theoretical constructs that have emerged from process sedimentology over the past century. Drawing on a wide range of knowledge bases, David Evans develops a more precise, contemporary till nomenclature and new investigatory strategies for understanding a critical aspect of glacial process sedimentology. Provides an in-depth discussion of subglacial sedimentary processes, with an emphasis on the origins of till matrix and terminal grade and the latest observations on till evolution Describes contemporary laboratory and modelling experiments on till evolution and techniques for measuring strain signatures in glacial deposits Develops an updated till nomenclature based on an array of knowledge bases and describes new strategies for field description and analysis of glacial diamictons Written by an internationally recognised expert in the field, this book represents an important step forward in the modern understanding of glacial process sedimentology. As such, Till: A Glacial Process Sedimentology is an indispensable resource for advanced undergraduates and researchers in sedimentology, glacier science and related areas.

Geoarchaeological studies can significantly enhance interpretations of human prehistory by allowing archaeologists to decipher from sediments and soils the effects of earth processes on the evidence of human activity. While a number of previous books have provided broad geographic and temporal treatments of geoarchaeology, this new volume presents a single author's view intended for North American archaeologists. Waters deals with those aspects of geoarchaeologyÑstratigraphy, site formation processes, and landscape reconstructionÑmost fundamental to archaeology, and he focuses on the late Quaternary of North America, permitting in-depth discussions of the concepts directly applicable to that research. Assuming no prior geologic knowledge on the part of the reader, Waters provides a background in fundamental geological processes and the basic tools of geoarchaeology. He then proceeds to relate specific physical processes, microenvironments, deposits, and landforms associated with riverine, desert, lake, glacial, cave, coastal, and other environments to archaeological site formation, location, and context. This practical volume illustrates the contributions of geoarchaeological investigations and demonstrates the need to make such studies an integral part of archaeological research. The text is enhanced by more than a hundred line drawings and photographs. CONTENTS 1. Research Objectives of Geoarchaeology 2.

During geologic spans of time, Earth's shifting tectonic plates, atmosphere, freezing water, thawing ice, flowing rivers, and evolving life have shaped Earth's surface features. The resulting hills, mountains, valleys, and plains shelter ecosystems that interact with all life and provide a record of Earth surface processes that extend back through Earth's history. Despite rapidly growing scientific knowledge of Earth surface interactions, and the increasing availability of new monitoring technologies, there is still little understanding of how these processes generate and degrade landscapes. Landscapes on the Edge identifies nine grand challenges in this emerging field of study and proposes four high-priority research initiatives. The book poses questions about how our planet's past can tell us about its future, how landscapes record climate and tectonics, and how Earth surface science can contribute to developing a sustainable living surface for future generations.

Reconstructing Human-Landscape Interactions demonstrates the high quality of work presented at the first Developing International Geoarchaeology conference (DIG 2005), held in Saint John, New Brunswick, Canada, and exemplifies the over-riding theme of this discipline. People have always used the landscape in many ways: as a place to live, as a place to grow crops, as a source of natural resources. Those actions leave their traces. The characteristics of the landscape constrain which activities are possible, just as social and cultural habits condition people's connection with the environment. Geoarchaeology is about finding the traces of these interactions, and using them to reconstruct how people in the past behaved in their environmental context. The material covered in the proceedings ranges from broad themes of climate change and landscape use, to more specific subjects such as river avulsion and the use of tidal ponds. The papers move us from the land to the coastal margin and back onto land to examine particular techniques. The final paper leads us beyond archaeology and points out that geoarchaeological data must contribute to the debate about the sustainability of present-day land-use practices: a fitting challenge to take us into the future.
