The Practical Encyclopedia of Rocks and Minerals is the ultimate photographic guide to the world of rocks and minerals, and how to build your own collection.
A comprehensive introduction explains the formation and classification of the many types of rock and mineral, with inspirational photographs of some of the world's most bizarre and beautiful examples. Expertly written text describes the impact of factors such as time, weather and water erosion on the development of rocks and minerals in the landscape, and the part played by natural phenomena such as volcanoes and earthquakes. It clarifies how contact with heat and pressure can affect external characteristics, and prompt the metamorphosis of one rock into another.
There is advice for the amateur geologist on using equipment, field work, maps, tools and home testing techniques, to identify and source geological specimens in the field.
In the second part of The Practical Encyclopedia of Rocks and Minerals a comprehensive photographic directory illustrates over 300 examples of minerals and rocks from all over the world. Specimens are grouped according to their chemical composition and characteristics, and all entries include quick-reference identification checklists to aid recognition.
Featuring over 800 photographs and artworks, this is a one-stop reference, visual encyclopedia and field guide on a richly consuming and endlessly fascinating subject.
John Farndon studied Earth Science at Cambridge University, UK, and has written a number of books and articles on the subject since, including Dorling Kindersley's Dictionary of the Earth, and the Rocks and Minerals section of their multimedia Earth science project. He has also written The Illustrated Guide to Rocks and Minerals.
