This book sets out to provide a simple introduction to the subject by means of illustrations and exercises, encouraging the student to visualise the problems concerned in three dimensions. Once an appreciation is gained of the nature of the problem, the formal solution using the projection becomes both logical and straightforward. The stereographic projection is an essential tool of the structural geologist which allows three-dimensional orientation data to be both represented and manipulated. It provides a way of graphically displaying the data collected. This is essential for the recognition and interpretation of patterns of preferred orientation. 'This is the book all teachers of stereographic projections have been waiting for! It is 115 pages of well-presented, clearly explained, generally well-illustrated text - in short it is user-friendly.' - Episodes - Int. Geoscience Newsmagazine, April 1996
