Minerals Encyclopedia

Mineral collecting by amateur “rockhounds” has never been more popular. Old quarries, road cuts, and exposed landscapes are being examined by new generations of minerals enthusiasts. Each needs a comprehensive guidebook with clear photographs and accurate data. This is it. In a thick but handy format, more than 700 different minerals and rocks are grouped by colour (for ease of location in the book) — blue, red, yellow, brown, green, white and black crystals; brown and grey sedimentary rocks; and meteorites for anyone lucky enough to find one. Each has a picture – four to a page—opposite detailed but clear data: Chemical formula; Hardness; Colour; Density; Lustre; Cleavage; Fracture; Tenacity; Crystal form; Similar minerals and where they are likely to occur. And many will have a diagram of its crystal form—up to four, for fluorite, for example. The Minerals Encyclopedia is unusual for the number of minerals it covers: more than 700 in 444 pages, with a useful glossary, an introduction to mineral collecting, and printed front and back flaps that offer quick reference in the field, and a measuring rule on the back cover. This is a superior reference for rockhounds, geology students and outdoors people with an interest in what’s under their feet. See more
