Comprising a guidebook and a full color CD-ROM, this reference set offers illustrated essentials to study mineralogy, applied to petrology. While there are some excellent reference works available on this subject, this work is unique for its data richness and its visual character.

With a collection of images that excels both in detail and aesthetics, 151 minerals are presented in more than 400 plates. Different facies and paragenesis, both in natural polarized light, are shown for every mineral and optical data, sketches of the crystal habitus, chemical composition, occurrence and a brief description are included. The accompanying user guide gives a general introduction to microscope mineral observation, systematic mineralogy, mineral chemistry, occurrence, stability, paragenesis, structural formula calculation and its use in petrology.

This compact set will serve as a field manual to students, researchers and professionals in geology, geological, mining, and mineral resources engineering to observe and determine minerals in their studies or field work.

About the Author

Dr. Michel Demange has devoted his career to regional geology and tectonics of metamorphic and magmatic terranes and to ore deposits. Graduated from the École Nationale Supérieure des Mines de Paris and holding a Docteur-es-Sciences from the University Pierre et Marie Curie, Paris VI, he has been active in a rich variety of geological projects and investigations around the world. In combination with his teaching and research activities at the École des Mines in Paris, France, he headed various research studies. This book benefits from the great experience in field studies, research and teaching and the wealth of data and images accumulated during his career. This book and its companion volume are both available in French from the Presses de l’École des Mines, Paris.
