A knowledge of structural geology is fundamental to understanding the processes by which the earth's crust has evolved. It is a subject of fundamental importance to students of geology, experienced field geologists and academic researchers as well as to petroleum and mining engineers. Structures on all scales are considered but the emphasis of the book is on those that can be seen on the scale of hand specimen or outcrop. Those beginning in structural geology will benefit from its direct expository style, congent arguments, and comprehensive use of experimental and analytical models to analyze rock structures.
