Manual of Mineralogy (after James D. Dana)

Comprehensive and up-to-date, this revised introductory text presents a balanced treatment of basic concepts in mineralogy and descriptive discussions of about 200 of the most common minerals. New in this 20th Edition are a more simplified approach to crystal morphology, a chapter on internal order and structure, a new chapter on gem minerals with four color plates, and revisions throughout the text which reflect a more quantitative approach.
