Book excerpt: This textbook is designed to aid the student in geological map interpretation. The book starts with basic concepts such as dip and strike, and progresses through a variety of exercises based on folds, faults and unconformities, up to and including the interpretation of Geological Survey Maps. In order to give a sense of reality to the text, frequent reference is made to actual examples on which many of the problem maps are based. Also included in the text are exercises concerned with bore-hole interpretation and correlation. The book, which is in two sections, is unique in that the second section contains worked solutions to the questions set in the first half.
