Principles of Rock Deformation

'The international standing of the author and the clarity of his explanation and illustration make the book a worthwhile addition to libraries worldwide.' Geological Magazine (about the French edition) '... it will prove valuable not only in undergraduate structural geology courses, but also to the interested non-specialist. The book is well illustrated with abundant line diagrams.' Geophysical Journal of the Royal Astronomical Society
