It's the classic work revised and updated! Identify over 500 of the most collectible minerals quickly and easily with this fully photographed field guide. And this new reissue makes identification easier, with new cleavability ratings for each entry alongside the handy classifications based on streak colour, Mohs' hardness and specific gravity. A complete introductory discussion of mineral forms and properties explains the essential criteria for recognition, and each of the hundreds of minerals (from Ankerite to Zinwaldite) is accompanied by information on its fracture, luster, chemical formula, aggregates, distinguishing characteristics and localities.
