Crystallization of Magmas part of Cutting Edge:Geochemistry:Activities
John Ayers, Vanderbilt University
Students use three methods to explore the crystallization behavior of a rock of known composition at 1 atmosphere pressure. This laboratory exercise illustrates various approaches used by geochemists and ...
Acid Mine Drainage Field-Lab Experience Round 1 part of Cutting Edge:Geochemistry:Activities
Greg Druschel, University of Vermont and State Agricultural College
This contribution outlines a trip with my Geochemistry class to the Ely Mine, a massive sulfide mine (Besshi-type) in east-central Vermont and the field work they did there. We spent a full day discussing the site, ...
Problem set: Constructing metamorphic phase diagrams using phase equilibria and the Clausius-Clapeyron equation part of Cutting Edge:Courses:Petrology:Teaching Examples
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 ...
Petrography and Petrogenesis of a Mid-Ocean Ridge Lava Suite part of Cutting Edge:Courses:Petrology:Teaching Examples
Matthew Smith, University of Florida; Mike Perfit, University of Florida
This activity is designed to accompany a set of thin sections available from the authors. Students investigate mid-ocean ride basalt petrography and relate observed mineralogic changes to relevant phase diagrams ...
T-X Phase Diagrams part of Cutting Edge:Courses:Petrology:Teaching Examples
Dexter Perkins, University of North Dakota-Main Campus
This is a 15 page tutorial and problem set designed to get students familiar with T-X diagrams, their implications, and uses.
Heat Capacity of Minerals: A Hands-On Introduction to Chemical Thermodynamics part of Cutting Edge:Courses: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, ...
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 ...
Geothermal Gradients part of Cutting Edge:Courses:Petrology:Teaching Examples
Cameron Davidson, Carleton College
In this problem set the students use two different equations to calculate a conductive geothermal gradient using a spreadsheet program like Excel. Once they have the geothermal gradient plotted, they are asked to ...
Learning Thermodynamics and Using Spreadsheets part of Cutting Edge:Courses:Petrology: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 ...
Introduction to Equilibrium Thermodynamics: Salt Dissolution part of Activities
Andrew Knudsen, Lawrence University;
Students dissolve simple salts, halite and sylvite, in water at different temperatures and explore the thermodynamics of this simple system to build a foundation for further studies.
