Petrology, Chapter 24: Metamorphic Mineral Assemblages

John Winter, Department of Geology


This 81-slide PowerPoint presentation reviews the phase rule in terms of metamorphic systems, using the brucite-periclase system as an example. Binary and ternary chemographic diagrams are used to explain compatibility in mineral assemblages. The presentation covers ternary diagrams for complicated systems, ACF and AKF diagrams, projections from apical phases, and J.B. Thompson's A(K)FM diagram is used as an alternative tool to apply to pelitic rocks. Lastly, a set of rules is laid out to help choose the appropriate chemographic diagram.
