A practical introduction to ionic compounds for both mineralogists and chemists, this book bridges the two disciplines. It explains the fundamental principles of the structure and bonding in minerals, and emphasizes the relationship of structure at the atomic level to the symmetry and properties of crystals. This is a great reference for those interested in the chemical and crystallographic properties of minerals.

The authors of this book point to the need for a strong cooperative relationship between research and education to halt declines and to regain some of the earlier vitality of both. Representatives of the scientific, educational, and government sectors look at the problems and prospects facingU.S. research and university education, presenting the perspectives of their own institutional biases and turning also to the experiences of Canada and Western Europe. The concerns,proposals, and requirements they express deal with areas of conflict and suggest possible solutions. Though their views sometimes diverge, the authors seek to define some basic principles that can guide the development of productive new policies.
