In recent years, Graham Park has been prolific in his writing for Dunedin Academic Press. In this new tome, he has produced what I suspect is a really great introduction to a range of key concepts and geological processes for both undergraduates and the interested, moderately well-informed amateur.

This is a new edition of the classic little guide on Blue John by Trevor Ford, who has now sadly passed away. It is published by the East Midlands Geology Society and has been revised, updated and expanded by Trevor’s colleagues, Tony Waltham and Noel Worley.
