Natural Radiation – A Tale of Two Minerals: presented by Dr. George R. Rossman: Minerals of the feldspar group are the most common phases volumetrically in the crust of planet Earth. Ideally, when they have the textbook-ideal, composition, they are colorless. But, in fact, there are many colorful varieties of feldspars that are popular with collectors.

Dr. George R. Rossman is Professor of Mineralogy in the Division of Geological and Planetary Sciences, California Institute of Technology, Pasadena, California, and President of the Mineralogical Society of Southern California. He got his B.S. degree in Chemistry and Mathematics from Wisconsin State University, Eau Claire, and his Ph.D. from Caltech in Chemistry. His principal research interests deal with the use spectroscopic probes to study minerals. His work addresses problems relating to the origin of color phenomena in minerals; phase identification; and the special role of metal ions in minerals.
