| This practical, up-to-date and authoritative guide will be indispensible for all those wishing to identify rocks, minerals and fossils, and is an ideal handbook for field work. For each mineral and type of rock, the physical and optical properties are listed, with discussions on their occurence and distinguishing features. For the fossils, their type, age and geographical distributions are given. The hundreds of full-colour photographs from the collection of the British Natural History Museum will prove invaluable, and the many informative illustrations will explain the technical concepts involved. |
