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, ...
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, ...
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.
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 ...
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 ...
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 ...
Modeling Exsolution (and Perthite Formation) as an Example of Complex-System Behavior part of Cutting Edge: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 ...
Introduction to Equilibrium Thermodynamics: Salt Dissolution part of Cutting Edge:Geochemistry: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.
