Glaciotectonism is an important component of modern glacial theory, gaining widespread recognition within the past 25 years. This book is the 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. It 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; and analogous deformation of non-glacial origin.
