Calculating Compositional Variation and Common Substitutions for Igneous and Metamorphic Minerals part of Cutting Edge:Courses:Petrology:Teaching Examples
Dave Mogk, Montana State University-Bozeman
This problem set uses Excel spreadsheets to calculate mineral formulae from analytical data (typically from the electron microprobe) using a variety of formulations that assume numerous variations of crystal ...

Modeling Exsolution (and Perthite Formation) as an Example of Complex-System Behavior part of Cutting Edge:Develop Program-Wide Abilities:Complex Systems:Teaching Activities
Dave Mogk, Montana State University-Bozeman; Barb Dutrow, Louisiana State University
Students use a physical model, computer simulation, examples from the natural world, visualizations, and overarching thought experiments to explore this phenomenon. Exsolution embodies attributes of a complex ...

Determining Mantle Temperature and Composition from Discontinuities part of Cutting Edge:Topics:Deep Earth:Activities
Anna Courtier, James Madison University
This pair of activities uses observations of mantle discontinuity structure to examine mantle heterogeneity and differences in the depth extent of melt sources for ridges and "hotspots." The first ...

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.

What Goes into Making Volcanic Arc Magmas, and How Do We Know It? part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Jeff Ryan, University of South Florida-St. Petersburg
This activity is a directed reading exercise focused on papers that have been key to our understanding of the major source contributors to subduction zone volcanic rocks.

Crystal Structures as Geobarometers part of Integrating Research and Education:Crystallography:Cpx Geobarometer
Kent Ratajeski, kratajeski@montana.edu Department of Earth Sciences, Montana State University, Bozeman, MT Published Jan. 4, 2005 Description This exercise is based on the recent formulation of a geobarometer ...

Plotting Compositions in 2-D and 3-D Space part of Cutting Edge:Courses: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 ...

Mole %, Weight %, Compositions and Projections part of Cutting Edge:Courses: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.

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.

Phase Equilibria part of Activities
Dexter Perkins, University of North Dakota-Main Campus
This is a short exercise that introduces basic thermodynamics.

Dexter Perkins, University of North Dakota-Main Campus
Introduction to sulfides and other ore minerals.

Mineral Commodities part of Activities
Dexter Perkins, University of North Dakota-Main Campus
This exercise introduces students to mineral commodities.

Symmetry Summary part of Activities
Dexter Perkins, University of North Dakota-Main Campus
This summary exercise involves crystal system and point group identification and stereo diagram construction.

Calculating Weight Percents and Normalizing Analyses part of Activities
Dexter Perkins
