These lecture notes discuss the use of three component systems in metamorphic petrology. Common triangular plots used in metamorphic rocks are presented with annotated ternary diagrams. The presentation includes four criteria for reducing the number of components in a system to a workable number. There is also discussion of the issue of lost information when reducing the number of components in a system.
