Deformation Mechanisms, Rheology and Tectonics: Current Status and Future Perspectives

Deformation Mechanisms, Rheology and Tectonics: Current Status and Future Perspectives Publisher: Geological Society of London Pages: 424 2003 ISBN 1862391173 PDF 35 MBThe motion and deformation of rocks are processes of fundamental importance in shaping the Earth, from outer crustal layers to the deep mantle. Reconstructions of the evolution of the Earth therefore require detailed knowledge of the geometry of deformation structures and their relative timing, of the motions leading to deformation structures and of the mechanisms governing these motions. This volume contains a collection of 22 papers on field, experimental and theoretical studies that add to our knowledge of these processes. They are a mixture of review papers on selected topics in the field of structural geology and tectonics and papers on current issues and new techniques and are grouped into four themes: The effect of fluids on deformation; The interpretation of Microstructures and textures; Deformation mechanisms and rheology of crust and upper mantle minerals; Crust and lithosphere tectonics.

Principles of Glacier Mechanics

Roger LeB. Hooke, "Principles of Glacier Mechanics"Cambridge University Press ISBN:0521544165 2 edition (March 21, 2005) PDF 448 pages 5105 KB

This book provides students and practising glaciologists with the tools they need to understand modern glaciology. Relatively simple concepts are introduced first, followed by mathematically more sophisticated chapters. A knowledge of basic calculus is assumed, but important concepts of physical processes are developed from elementary principles. Emphasis is placed on connections between modern research in glaciology and the origin of features of glacial landscapes. Student exercises are included. This new edition builds on the successful first edition: it has been completely updated, and important new sections and whole chapters have been added. Principles of Glacier Mechanics is designed to be used as a primary textbook in upper division and graduate courses in glaciology, and can be used as either a primary or supplementary text in courses in glacial geology. Practising glacial geologists and glaciologists will also find it useful as a reference book.
