Introduction to Mineral Equilibria part of Teaching Examples

Dexter Perkins, University of North Dakota-Main Campus

This activity features a short problem set to be used in class. It helps focus the discussion, while providing a starting point for an introduction to mineral reactions and phase diagrams.

Interpreting T-X Diagrams part of Teaching Examples

Dexter Perkins, University of North Dakota-Main Campus

This exercise is designed to help students learn how to interpret T-X phase diagrams. It also introduces them to the systematics of reactions involving a group of minerals.

Schrinemaker Analysis - Problem #1: Analysis of an Invariant Point part of Teaching Examples

Dexter Perkins, University of North Dakota-Main Campus

This is a standard Schreinemakers problem: identifying the sequence of stable and metastable reactions around an invariant point.

Schreinemakers Analysis - Problem #2: Analysis of an Invariant Point with Application of the Clausius-Clapeyron Equation part of Teaching Examples

Dexter Perkins, University of North Dakota-Main Campus

This is a standard Schreinemakers problem: identifying the sequence of stable and metastable reactions around an invariant point. The added wrinkle is that they use the Clausius-Clapeyron Equation to calculate ...

Rb-Sr isotope in-class exercise part of Teaching Examples

Allen Glazner

This set of problems involves calculations of changes in radiogenic isotope ratios. It requires students to understand the concept of an isochron and how isotope ratios change (or do not change) during magma mixing ...

Metastability during metamorphism (reading a metamorphic petrology paper from the literature) part of Teaching Examples

William Peck, Colgate University

I use this problem set as a way to introduce students (mostly sophomores) to reading a technical article from the literature. The paper is Austrheim, H, 1987, Eclogitization of lower crustal granulites by fluid ...

Thermobarometry Problem Set part of Teaching Examples

Jane Selverstone

This homework assignment gives students first-hand experience with thermobarometric calculations. Because many of my students are math challenged, I give them a choice of solving the equations by hand or with ...

Major Element Control Presentation part of Teaching Examples

Kurt Hollocher, Union College (Lincoln, NE)

The presentation is an introduction to the control of magma chemical compositions by the fractionation of crystallizing phases. It is followed by a lab exercise where students interpret volcanic rock petrology and ...

Phase Diagrams and Chemographic Projections part of Teaching Examples

Dexter Perkins, University of North Dakota-Main Campus

This exercise is a good way to get students thinking about the phase rule, metastable and stable reactions and phase diagrams. It can be done in class or as homework.

Learning Thermodynamics and Using Spreadsheets part of Teaching Examples

Sumit Chakraborty and Somnath Dasgupta

These files contain a set of three Excel files to balance mineral reactions, to explore variation of thermodynamic properties as a function of P, T and composition and to explore stability of different mineral ...
