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 ...
Determining Mantle Temperature and Composition from Discontinuities part of Cutting Edge:Deep Earth:Activities
Anna Courtier, James Madison University
This pair of activities uses observations of mantle discontinuity structure to examine mantle heterogeneity and differences in the depth extent of melt sources for ridges and "hotspots." The first ...
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

Acid Mine Drainage Field-Lab Experience Round 1 part of 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, ...
Quiz and in-class worksheet part of Activities
Karen Hudson-Edwards, Birkbeck University of London
For 1st year 'Introduction to Geochemistry' a pre-lecture quiz reviewing the previous weeks' lecture materials an in-class worksheet allowing students to practice skills relating to chemical ...
Relationship between mineral weathering and groundwater composition part of Activities
Nancy Hinman, University of Montana-Missoula, The
By observing changes in rocks exposed to chemical weathering, students are to infer resulting changes to the chemical composition of groundwater. Students are required to justify their inferences through the use of ...
Compositional Diversity in Volcanic Suites part of Activities
Kent Ratajeski, University of Kentucky
In this exercise, students use geochemical data downloaded from the GEOROC database to explore the origins of compositional variation among volcanic rocks associated with the Yellowstone and Crater Lake calderas.
Spreadsheet analysis of chemical hydrographs part of Cutting Edge:Hydrogeology:Activities
This is a good activity to have students practice spreadsheet analysis skills on a medium large data set. It also helps them understand stream hydrographs and baseflow/quickflow components.
Rayleigh fractionation visualization part of Cutting Edge:Climate Change:Activities
E. Christa Farmer, Hofstra University
A MS Excel spreadsheet gives an account of Rayleigh fractionation, the progressive removal of the heavier oxygen isotope as a moist air parcel moves from the subtropics to the high latitudes. This exercise is ...
What can zircons tell us about the Early Earth? part of Cutting Edge:Early Earth:Activities
Aaron Cavosie, University of Puerto Rico; Julie Baldwin, University of Montana-Missoula, The; Darrell Henry, Louisiana State University
This image shows an array of Jack Hill zircons arranged on a piece of tape prior to casting in epoxy. Details Students create U-Pb concordia plots in Excel to experience the methods used to date the worlds oldest ...
