Mole %, Weight %, Compositions and Projections part of Cutting Edge:Petrology:Teaching Examples
Dexter Perkins, University of North Dakota-Main Campus
This is an introductory exercise intended to get students thinking about mole vs weight % and about the power and problems of projections.

Plotting Compositions in 2-D and 3-D Space part of Cutting Edge:Petrology:Teaching Examples
Dexter Perkins, University of North Dakota-Main Campus
This is a fairly short exercise that can be used for an in-class cooperative learning project or as homework. It includes LOTS of explanation and so is sort of a tutorial. I use it in my petrology class because it ...

Mineral Classification part of Activities

Point Groups part of Activities
, University of Colorado at Boulder
This mineralogy problem set tasks students with determining the point group Hermann-Mauguin symbol and crystal system for crystal stereograms.

Calculating Weight Percents and Normalizing Analyses part of Activities
Dexter Perkins
This exercise involves converting chemical analyses to mineral formulas, and mineral formulas to oxide and element weight percents.

Plagioclase Phase Diagram part of Activities
Dexter Perkins, University of North Dakota-Main Campus
This short exercise involves the binary plagioclase "two-phase loop" phase diagram.

Crystallization and Melting of Diopside - Anorthite part of Activities
Dexter Perkins, University of North Dakota-Main Campus
This short exercise introduces students to the binary phase diagram in the diopside-anorthite system that contains a eutectic invariant point.
