Minerals and Light part of Cutting Edge:Mineralogy:Activities
Optical Mineralogy and thin sections just blew me away when I first was exposed to them. (Of course that was the psychedelic 60's!) Because of my experience, I've always thought that we might attract a major or two if we introduced first-year students to interference colors and such. Therefore, this exercise is primarily intended to be used in an introductory (physical) geology class, perhaps for advanced students or as an extra credit project. It may also be appropriate as a brief introduction ("teaser"?) to optics in a mineralogy or optical class.
