Maps are the earth scientist's most fundamental tool. Accurate geological maps are the basis of geological work, in the field and in the laboratory. Students of geology must learn not only to understand them - but also how to construct them for themselves. This book introduces geological maps and mapping in a practical way. Abstract and idealistic treatments have been avoided and almost all the examples used are taken from real maps and real situations around the world. Use of three-dimensional diagrams and eight pages of colour maps coupled with up-to-date text will make this a useful book for all earth science students and will also be of interest to amateur geologists and geographers.
