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'.

'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
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'.

' book that... will give you a thorough understanding of geological
maps and enable you to "read" a geology map and visualise the
subsurface structure for yourself.'
