About this book

This title is a concise and accessible textbook providing simple structural terminology and map problems which introduce geological structures. Each topic is explained and illustrated by figures, and exercises follow on successive maps.

The 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 a new map from the British Geological Survey illustrates a real area. There is more on outcrop patterns and 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.

An Introduction to Geological Structures and Maps 'has been a friend to me as an undergraduate and also during the 32 years I have been teaching geology to Civil Engineering undergraduates. I have seen how it has changed over the years. None of these revisions have been as significant and as exciting as those in this 8th edition. The new chapter on strata is an excellent addition as is the new enhanced chapter on igneous and impact features. The most striking feature however, is the inclusion of colour photographs of geological features and structures. These really bring the book alive. The new map problems and exercises are excellent. It is great to see a colour extract of a published BGS map being included. I recommend this book to both students and teachers'. -- Dr. Marcus C. Matthews, Senior Lecturer in Geotechnical Engineering, Faculty of Engineering and Physical Sciences, University of Surrey, UK 20110401 'An Introduction to Geological Structure and Maps has been a prescribed textbook in our department for more than two decades and many a student has started their geological career as an undergraduate student working through "Bennison maps". The new eighth edition proves to be a major improvement on previous editions, with the addition of a more theoretical background on certain geological structures and concepts, backed up by some excellent diagrams and photo illustrations... The section on igneous and impact features has been expanded quite a lot, [and] I find the additional pictures and background information very helpful. Chapter 12 on economic problems will be very helpful, too...This textbook will be a very valuable resource and teaching tool to undergraduate students and will remain a compulsory prescribed textbook in our department for many years to come'. -- Gideon Brunsdon, Geology Lecturer, Nelson Mandela Metropolitan University, South Africa 20110510 An Introduction to Geological Structures and Maps is a testament to its ability to remain relevant to students... concise and accessible...I welcome this "old friend" in its revitalized form'. -- ESTA 20110703
