The special feature of the 6th edition of Winkler's textbook is the large number of quantitative phase diagrams. They show the relationship among minerals as a function of variables which control chemical reactions in metamorphic rocks. These diagrams are unique: their computation was made possible by recent compilations of thermodynamic data of geologic substances and advanced phase diagram software over the past few years.
