An Introduction to Geological Structures and Maps 6/e is a concise text that leads the student from the simplest ideas on geological structures right through a first on geological mapping. It is designed to help students working with little or no supervision. Each new topic is explained and illustrated by figures, and exercises are set on succeeding maps. The sixth edition has been completely revised and updated. It includes more problems to make the progression from the simplest maps to the most advanced even more gradual, and the maps and figures have been redrawn throughout. A new chapter on planetary geology can be used to interpret geological information being obtained from elsewhere in the solar system.
