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.

Glaciotectonism is an important component of modern glacial theory, gaining widespread recognition within the past 25 years. This book is outcome of compiling maps of glaciotectonic structures and landforms for North America and central Europe, which is the basis for better understanding the role of glaciotectonism as a key component of glacial theory.Glaciotectonism is intented to provide a comprehensive review and description of glaciotectonic phenomena. The subject matter is arranged in three broad sections. First, definitions, principles, and methodologies of glaciotectonics in the field as well as in the laboratory are described. Next, case histories of glaciotectonic structures and landforms from the land and continental shelf regions of North America and Eurasia are then covered in detail. Practical applications for mining, highway construction, and other human activities are also described. The last part of the book covers regional and continental distribution of glaciotectonic phenomena, dynamics of glaciotectonic deformation, and analogous non-glacial deformation.* Provides definitions, principles, and methodology of investigation for glaciotectonic phenomena * Features case histories of glaciotectonic structures and landforms from the glaciated land and continental shelf regions of North America and Eurasia* Analyzes mechanical and theoretical glaciotectonic deformation; analogous deformation of non-glacial origin

In combining and revising the two titles 'Past Glacial Environments' and 'Modern Glacial Environments', Dr Menzies and his contributors provide the most comprehensive and wide-ranging book ever prepared on both topics. This text is produced with the student mind, providing accessibility to a complex subject and introducing topics that provide the fundamental underpinnings of knowledge on glaciers, ice sheets, their sediments and landscapes. Modern and Past Glacial Environments features a large collection of photographs, line diagrams and tables and includes examples of glacial environments and landscapes which are drawn from a world wide perspective. Together with a web- based set of current and comprehensive references and bibliographic sources, it provides an ideal reference text. This survey includes coverage of the glaciology, geomorphology and sedimentology of modern glaciers and ice sheets, and the sediments and forms generated within Pleistocene and pre-Pleistocene glacial environments. Quaternary scientists and students will find this work their first point of reference. Likewise students of Physical Geography, Geology, Earth Science, Engineering Geology, Civil Engineering, and Environmental Sciences should find this a useful guide and reference to Glacial Geomorphology and Geology. - Essential new academic version - Highest contributors in their fields - Well reviewed first editions

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.

Lowland glaciers are usually considered the best analogs for formerly glaciated areas and as such, many Icelandic glaciers have been intensively investigated with regard to process-orientated sediment-landform interrelationships. The Mýrdalsjökull ice cap has, thus, served as an excellent "ice-age laboratory." Furthermore, a substantial effort has been directed toward understanding the interaction between volcanic activity and glacier response, such as meltwater outbursts (jökulhlaups) and sudden events of rapidly flowing glacier ice. The book reviews the following themes related to Mýrdalsjökull: glaciology, glacial and quaternary geology, sedimentology, tephrochronology and eruption history of Katla, and crustal movements. All authors are involved in research about the subglacial Katla volcano and Mýrdalsjökull. - Book covers all aspects of the ice cap and volcano dynamics - Comprehensive reviews with updated results - Editors and authors are well established scientists with research experience from Myrdalsjokull - Standard reference work for Myrdalsjokull
