"The book is very instructive with a large number of tables and figures to illustrate the various topics. The appendices are very useful as is a very comprehensive reference list. Theoretical Geochemistry illustrates well what can and cannot be accomplished through computational methods." --Geochemica et Cosmochemica Acta"The first to attempt a broad survey of the 'quantum earth.' . . . the authors did a rather thorough job of reporting: over 1100 references are included in the bibliography. The presentation is detailed and relies almost entirely on examples from published papers. . . . very useful. . . . invaluable as a guide to the literature for graduate seminar courses. Those of us who are interested in the earth owe the authors a debt of gratitude for the great effort it took to review so much of the present literature. . . . well produced; it has few typos, the text is easy to read and the binding seems solid." --Pure and Applied Geophysics"This text by Tossell and Vaughan is outstanding and timely. This book provides the first major introduction and review of such advanced geochemical methods and shows how they can be applied to mineralogy. For anybody interested in the way in which geochemistry will evolve in the 21st century, this book is essential reading. The authors are to be congratulated in producing a first-class contribution to literature." --R.J. Price, Mineralogical Magazine"This is a welcome contribution that presents a comprehensive account of the research of the authors and of others concerning the quantum theory of electronic energy levels in geologically interesting materials and of the related experimental spectroscopy....Chapters 4,5, and 6...are excellent presentations....A most welcome account of the advance of knowledge in this special interdisciplinary field." --Geochimica and Cosmochimica Acta
