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.

This is one of the oldest of the GA’s guides and is currently in its third edition (the first having been published in 1957 and the second in 1972). Although there have been changes in classification and so on, the general exposures are largely as good as they used to be – or they were the last time I went!

I like fossils, but it is always nice to have a brief but informative guide to the actual science behind one’s finds. And this Dunedin guide certainly fits the bill for amateurs and undergraduates alike.

This is a new guide in Dunedin’s ‘Introducing …’ range of books, covering the branch of geology that studies rock layers (strata) and layering (stratification), primarily in sedimentary rocks, but also layered igneous rocks. In this way, it is intended for students and amateur geologist, rather than the academic earth scientist.

I have to admit that I hadn’t heard of ‘hydrogeology’ before, but I should have. Hydrogeology is an important and vibrant sub-set of geological science, dealing with the distribution and movement of water –groundwater – in the Earth’s soil and rocks. Groundwater transport is one part of the overall hydrological cycle in which water is transferred by evaporation from the oceans and seas into the atmosphere.

I really like the ‘Introducing ….’ series publish by Dunedin Academic Press, as you will have ascertained, if you have read the many reviews I have included in this magazine. This second edition of Introducing Sedimentology by Stuart Jones updates the version I reviewed a while ago (see Book review: Introducing Sedimentology, by Stuart Jones), and I found it equally enjoyable.
