Under The Microscope

VANISHING VOLCANOES, by Lloyd Homer and Phil Moore; Landscape Publications 1993; $49.95

This book, subtitled A guide to the landforms and rock formation of Coromandel Peninsula, is the long-awaited second of the guides to New Zealand geological features by the Institute of Geological and Nuclear Science. Homer and Moore have again combined to produce an outstanding work.

Twenty-six locations from Karangahake in the south to Fletcher Bay in the north, including some of the offshore islands, have been described and illustrated by photograph and diagram. Each location has its geological history described and the significance of its features explained.

Moore's text is simple and lucid, and clearly explains the origins and history of development of the features illustrated. A very useful explanation of rock types, volcanoes and geologic history of the area prefaces the locations descriptions. Local history and legend have also been included where appropriate for some of the features.

Homer's photography is, as usual, superb, and has been well presented by the publisher. The photographs clearly illustrate the feature being described. Most people have a fascination with volcanoes, and some of the more spectacular scenes enhance the awe and wonder we have for volcanic features.

As with the earlier volume Reading the Rocks, the guide to the Wairarapa coast, there are six laminated cards for field use included in a pocket in the back of the book. This allows you to read the book in the comfort of your home, and then take the cards, which have a summary of each location with small-scale maps, diagrams and photographs, into the more variable weather conditions experienced in the field.

This book is thoroughly recommended for anyone with an interest in volcanoes or New Zealand's natural history. It has a place in schools for both staff and student use; in the library for reference and in the classroom as a text. Schools that are able to use the locations for field work would be very foolish not to have several copies, while those that cannot get to the Coromandel Peninsula should have at least one or two copies available for reference use.
