How Effective is a Remediation System at a Regional Landfill? part of Activities
Kevin Theissen, University of St. Thomas (MN)
In this activity, students begin exploring the effectiveness of a remediation system installed at a closed landfill system. Students learn the importance of redox chemistry in a real-world context and build field ...
Marine Oxygen Isotopes and Changes in Global Ice Volume part of Cutting Edge:Climate Change:Activities
Ben Laabs, SUNY College at Geneseo
Students explore marine oxygen-isotope data from cores collected by the Ocean Drilling Program. The activity gives students access to real paleoclimate data, develops their skills in organizing and graphing data, ...
Problem set: Constructing metamorphic phase diagrams using phase equilibria and the Clausius-Clapeyron equation part of Cutting Edge: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 ...
Teaching Stable Isotope Geochemistry in an Undergraduate Petrology or Geochemistry Course part of Cutting Edge:Petrology:Teaching Examples
This assignment includes three reading assignments for students that (1) introduce the basics of stable isotope geochemistry, (2) explain carbon and oxygen isotopic shifts that result from volatilization and/or ...
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, ...
Calculating Compositional Variation and Common Substitutions for Igneous and Metamorphic Minerals part of Cutting Edge: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 ...
Using Dynamic Digital Maps to Teach Petrology part of Cutting Edge:Petrology:Teaching Examples
Christopher D. Condit
In this session we will examine how to utilize Dynamic Digital Maps (DDMs) in undergraduate petrology courses to bring inaccessible and exciting volcanic field areas to the students in the classroom and to engage ...
Timing of mineralization in the palm of your hand: Cross-cutting relations, copper minerals and ore-forming hydrothermal fluid evolution part of Cutting Edge:Petrology:Teaching Examples
Barb Dutrow, Louisiana State University
This lab is designed to familiarize students with the geologic history of an ore-deposit, deciphered in the palm of your hand. By determining cross cutting relations of veins and mineralogy, students decipher the ...
Extending Mineralogy by Electron Microprobe Analysis part of Cutting Edge:Petrology:Teaching Examples
John Goodge, University of Minnesota-Duluth
This lab is designed to be a highly interactive lab session for a petrology course, where instructors provide a minimal level of essential background and then the entire group works together to explore mineral ...
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 ...
Weathering of Igneous, Metamorphic, and Sedimentary Rocks in a Semi-Arid Climate - An Engineering Application of Petrology part of Cutting Edge:Petrology:Teaching Examples
Wendy Harrison, National Science Foundation; Ric Wendlandt, Colorado School of Mines
Students examine soils developed on igneous, metamorphic, and sedimentary rocks near Denver, Colorado. The 2-week exercise includes sample collection, description, and preparation, determining clay mineralogy by ...
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 ...
Igneous Rock Compositions and Plate Tectonics part of Cutting Edge:Petrology:Teaching Examples
