Book Description
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.

Book Description
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.

Book Description
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

Book Description
Until now no overview of the Quaternary deposits of northeastern Europe has been available. This book fills the gap. It presents the state of research on Quaternary stratigraphy and geology, with emphasis on glacial deposits, discusses the general scientific ideas and gives an overview of the methods of investigation, some of which have rarely been applied elsewhere. It has become apparent that the region covered has many environmental problems, and a proper understanding of the Quaternary deposits is a basic requirement for dealing with them. The same is true for civil engineering. In the formerly glaciated areas almost all construction sites for roads and houses will encounter glacial deposits. This volume provides an authoritative and fascinating overview for anyone planning to venture into this field. In its 53 regional chapters the book covers Finland, Estonia, Latvia, Lithuania, Russia, Ukraine, Belarus, Poland, the Czech Republic and eastern Germany. From the text it becomes clear that not all the stratigraphical schemes are yet fully compatible or comprehensible. There can be no doubt, however, that the east was subjected to very extensive ice advances during the earlier Pleistocene. Also, in contrast to western Europe, there was a significant Early Weichselian ice advance, although not as extensive as the last, Late Weichselian event. The book is illustrated by 421 figures and 74 colour plates (mostly photographs). There are 23 tables, a detailed index and a list of over 1000 references, providing a unique collection of northeastern European geoscience literature, much of which has so far escaped the attention of western scientists. The volume, composed of contributions by 60 scientists, completes the trilogy on glacial deposits of northern Europe. Together with its two companion volumes, the Glacial deposits in North-West Europe and the Glacial Deposits in Great Britain and Ireland, it represents an invaluable source of information for the geoscientist, the advanced student or the amateur.

Book Description
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
