An Introduction to Geological Structures and Maps is a concise and accessible textbook which leads students in easy stages from the simplest ideas on geological structures to more advanced geological mapping techniques. It is a perfect introduction to mapping for students of geology, engineering geology and civil engineering.Each topic is explained and illustrated by figures, and exercises follow on successive maps. If students are unable to complete an exercise, they can read on to obtain more specific instructions on how theory may be used to solve the problem. An appendix at the end of the book provides the solutions.This new, eighth edition contains simplified introductory matter to make the subject as easy to grasp as possible. Colour photographs illustrating geological structures bring the subject to life and new maps from the British Geological Survey illustrate real areas. There is more on outcrop patterns, which will help students to think in 3D, and on structures and the relationship of topography to geological structure. Cliff sections have been added to reinforce the concept of apparent dip. The section on planetary geology has been more closely tied to igneous geology to aid understanding of the connection between the two. Finally, a new map on economic geology has been added for the benefit of engineering students.A geological glossary helps students to understand and memorise key terms and a new, colourful, text design enlivens the appearance of this popular book.
