"An Introduction to Geological Structures and Maps" is a concise text that leads the students in easy stages from the simplest ideas on geological structures right through to the more advanced geological mapping techniques. The approach this book adopts is designed to help students with little or no supervision: each new topic is simply explained and illustrated by figures, and exercises are set on successive maps. If students are unable to complete a problem, they can read on to obtain more specific instructions on how theory may be used to solve the problem in question. This considerably enlarged seventh edition aims to make the book even more user friendly and bring it into line with present trends in map syllabuses. This edition includes photographs that will significantly add to the understanding of geological structures already illustrated by text-figures and block diagrams in the appendix. The appendix has been fully updated and now includes completed sections of all maps and solutions to the map problems, which enables the reader to check that his or her attempts have been successfully carried out.
