Igneous Rock Compositions and Plate Tectonics part of Cutting Edge:Petrology:Teaching Examples
Allen Glazner, University of North Carolina at Chapel Hill
In this exercise, students use whole-rock major- and trace-element compositions of igneous rocks from a variety of tectonic settings and locations to explore the importance of plate setting in determining magma ...
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 ...
Volcanoes Around the Globe part of Cutting Edge:Visualization:Examples
Mark Abolins, Middle Tennessee State University
Undergraduate non-majors use the Arcview geographic information system (GIS) to explore volcanic hazards and the geochemistry of volcanic rocks. Students explore geochemical data from the GEOROC global database and ...
An In-Class Demonstration and Activity Using the FCAEM Remotely Operable Electron Microprobe part of Activities
Jeff Ryan, University of South Florida
This activity takes advantage of the full remote operation capabilities of the electron microprobe system available through the Florida Center for Analytical Electron Microscopy (FCAEM) at Florida International ...
Experiments with Ultraviolet Radiation and the Greenhouse Effect part of Activities
Melanie Szulczewski, University of Mary Washington
Students use a solar cooker to model the greenhouse effect. They also develop their own experiments to examine the strength of ultraviolet radiation from the sun with various protective materials.
What does the core/mantle boundary look like? part of Cutting Edge:Deep Earth:Activities
Suzanne Baldwin, Syracuse University
This activity explores how earth scientists infer what materials are present at the core mantle boundary and what this boundary might look like. It provides students with the opportunity to contribute to the ...
Petrology/Geochemistry/Mineralogy/Structure of Shear zones in St. Lawrence County part of Cutting Edge:Structural Geology:Activities
Robert Badger, SUNY Potsdam
Field and petrographic examination of shear zones in northern New York -
Rock Samples and Geochemistry Analyses part of Activities
Maria Rosa Lourdes, Bahia Federal University
We will emphasize the importance of rock sampling and preparation for geochemistry analyses.
Nitrous Oxide Transport and Transformation part of Activities
Pierre-Andre Jacinthe, Indiana University-Purdue University-Indianapolis
In this laboratory exercise, students gain experience manipulating gas concentration data, determining soil properties related to transport of gases through porous medium like soils. This exercise is appropriate ...
Integrating research methods into geochemistry using local resources part of Activities
Jeanette Pope, DePauw University
This is a semester-long project that introduces students to research methods and practices. Students learn both field and lab techniques and how to develop testable hypotheses. Using local resources is an easy way ...
Geochemical debates part of Activities
Nancy Hinman, University of Montana-Missoula, The
Students are given the task of defending or refuting a statement about global warming. Students are expected to work in groups to develop the strongest argument in their favor, but must also address issues raised ...
Crystal Structures as Geobarometers part of Cutting Edge:Mineralogy:Activities
Kent Ratajeski, University of Kentucky
In this exercise, designed for undergraduate igneous petrology or advanced mineralogy courses, students download a series of crystal structures from the American Mineralogist Crystal Structure Database to explore ...
Constraints and Implications of Groundwater Temperature on the Formation of Mississippi Valley-type Zn-Pb Deposits part of Cutting Edge:Hydrogeology:Activities
Martin Appold, University of Missouri-Columbia
This assignment illustrates the role of groundwater in transporting heat and its implications for the formation of hydrothermal ore deposits. The assignment uses a combination of graphs and algebraic equations that ...
Where Did That Quartzite Clast Come From?: A Problem-Based Provenance Study part of Cutting Edge:Sedimentary Geology:Activities
Andrew Hanson, University of Nevada-Las Vegas
Students conducting geochemical provenance studies are forced to deal with obvious things such as manipulating/interpreting geochemical data, but also must deal less obvious factors such as considering earlier ...
Variation Diagrams and the Evolution of Thingmuli Lavas, Iceland part of Cutting Edge:Petrology:Teaching Examples
Jeff Tepper, University of Puget Sound
In this problem set students are provided with an EXCEL spreadsheet containing major element analyses of lavas frm Thingmuli Volcano in Iceland. They are asked to construct variation diagrams (Harker plots) and ...
