Heat Capacity of Minerals: A Hands-On Introduction to Chemical Thermodynamics part of Cutting Edge:Mineralogy:Activities

David Bailey, Hamilton College

Minerals are inorganic chemical compounds with a wide range of physical and chemical properties. Geologists frequently measure and observe properties such as hardness, specific gravity, color, etc. Unfortunately, ...

Where is that chunk of crust going? part of Cutting Edge:Introductory Courses:Activities

Vince Cronin, Baylor University

I introduce students to GPS, frames of reference, and the permanent GPS stations in the EarthScope Plate Boundary Observatory (PBO) in class, and obtain near-real-time data for two stations from UNAVCO. We use ...

Problem set: Constructing metamorphic phase diagrams using phase equilibria and the Clausius-Clapeyron equation part of Cutting Edge:Petrology:Teaching Examples

Mark Brandriss

In this problem set students construct a P-T phase diagram for the aluminosilicate polymorphs based on experimental phase equilibria and application of the Clausius-Clapeyron equation. The problem set uses unit ...

Calculating a Simple Phase Diagram: Diamond=Graphite part of Cutting Edge:Petrology:Teaching Examples

Dexter Perkins, University of North Dakota-Main Campus

This is a very short exercise designed to get students to understand how the Gibbs energy equation is used to calculate the location of a reaction in P-T space. I use it in-class and have students work on it in ...

Working with Electron Microprobe Data from a High Pressure Experiment - Calculating Mineral Formulas, Unit Cell Content, and Geothermometry part of Cutting Edge:Petrology:Teaching Examples

Brandon Schwab, Humboldt State University

In this problem set students use electron microprobe analyses of a peridotite partial melting experiment to determine mineral formulas, calculate unit cell content, plot results on a classification diagram, and use ...

Introduction to Gibbs Energy part of Cutting Edge:Petrology:Teaching Examples

Dexter Perkins, University of North Dakota-Main Campus

This is a short project that can be used in-class or as homework. It involves just a few questions and it is intended to help students understand the idea of Gibbs free energy.

Estimating Exchange Rates of Water in Embayments using Simple Budget Equations. part of Quantitative Skills:Activity Collection

Keith Sverdrup, University of Wisconsin-Milwaukee

Simple budgets may be used to estimate the exchange of water in embayments that capitalize on the concept of steady state and conservation principals. This is especially true for bays that experience a significant exchange of freshwater. This exchange of freshwater may reduce the average salt concentration in the bay compared to seawater if it involves addition of freshwater from rivers, R, and/or precipitation, P. Alternatively, it may increase the average salt concentration in the bay compared to seawater if there is relatively little river input and high evaporation, E. Since freshwater input changes the salt concentration in the bay, and salt is a conservative material, it is possible to combine two steady state budgets for a bay, one for salt and one for water, to solve for the magnitude of the water flows that enter and exit the bay mouth. Students will make actual calculations for the inflow and outflow of water to Puget Sound, Washington and the Mediterranean Sea and compare them to actual measured values.
