This text describes the theory and practice of optical mineralogy in terms useful to all practitioners--from the beginning student to the professional--in field and laboratory geology as well as in industrial and environmental mineralogy. The authors aim to provide the simplest possible access to the most powerful techniques of optical crystal identification. Containing original research results found in no other text, the book emphasizes practical theoretical material and methods for studying both thin sections of rocks and immersions of mineral grains in refractive index liquids. A major goal of this text is to allow precise determination of refractive index and the essential composition of crystals belonging to important mineral groups such as olivine, feldspar and pyroxene. New methods for achieving this are developed for both white light and colored light of variable wavelength. Among the book's unique features is the color fringe chart developed by Professor Morse for estimating both the direction and the degree of mismatch between the refractive index of a crystal and that of the surrounding liquid medium in the immersion method. Further, a new algebraic treatment of the dispersion method allows a high precision of match between crystal and liquid. An original classification of interference figures aids crystal identification. Worked examples of refractive index determination and crystal identification are given for each optical class of crystals. The optic orientation of optically biaxial crystals is illustrated with examples from each crystal system portrayed in stereographic projection. Principles and applications of crystal identification with the dispersion method are developed in a separate chapter. The final chapter is a practical, step-by-step guide to crystal identification in thin section or immersion. An identification table for the most common rock-forming minerals is appended, and a separate appendix treats the identification of the most common asbestos minerals, including the dispersion staining method used by most environmental laboratories.

Review:

Crystal Identification with the Polarizing Microscope is a wonderful, user-friendly book. The authors state that their emphasis is practical but with enough theory to make rigorous understanding possible.....book is suitable over the entire range from an undergraduate text to a guide for advanced graduate students. The two strong points of the book are that it conveys the vast and varied experience of its authors, and that it uses immersion techniques to teach theory - The Canadian Mineralogist, vol.33; Crystal Identification with the Polarizing Microscope is a wonderful, user-friendly book.

Synopsis:

The book reviews optical theory and methodology, with an emphasis on dispersion methods. The contents cover asbestos identification and include original methods developed by Morse. Some of the simpler measurements of optical mineralogy are so precise and powerful that they provide all a beginning student needs. Very little training and almost no theory are needed to achieve these skills. But there inevitably comes a time when theory is needed, either to get on with the art, or simply to reconstruct from first principles what is going on, when rote memory fails. "Crystal Identification with the Polarizing Microscope" provides both the methods and the theoretical background for practitioners at all levels of experience. It should serve the needs of industrial and forensic scientists, as well as petrographers who deal with rocks and upper-level and graduate students. This book should be of interest to industrial and forensic scientists; petrographers; and upper-level and postgraduate mineralogists.
