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 ...
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 ...
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 ...
Chemical Differentiation in the Palisades Sill part of Cutting Edge:Petrology:Teaching Examples
Matthew Gorring, Montclair State University
The purpose of this assignment is for students to synthesize field observations, petrography, and whole-rock chemical analyses in order to investigate chemical differentiation processes in a basaltic magma chamber. ...
Origins of Mafic Enclaves in the Dinkey Creek Pluton, Central Sierra Nevada Batholith, California part of Cutting Edge:Petrology:Teaching Examples
Jade Star Lackey, Pomona College;
In this lab exercise, students use and substantial spreadsheet of major, minor and trace element data compiled from studies of the Dinkey Creek pluton (Sierra Nevada batholith) and its microgranular mafic enclaves. ...
Major Element Fractionation During Differentiation part of Cutting Edge:Petrology:Teaching Examples
This problem set introduces some of the more advanced uses of Excel to not only calculate how the chemistry of a magma changes with crystallization but also to see how the liquidus assemblage can drastically change ...
Magma Modification in the central Sierra Nevada Batholith part of Cutting Edge:Petrology:Teaching Examples
Jennifer Wenner, University of Wisconsin-Oshkosh
This exercise is centered around a suite of rocks from the Sierra Nevada batholith. The activities are designed to give petrology students a capstone experience for the igneous portion of the upper-level Petrology ...
Compositional Diversity in Volcanic Suites part of Cutting Edge:Geochemistry: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.
Differentiation and Discrimination of Big Bend Ranch State Park Igneous Rocks part of Cutting Edge:Petrology:Teaching Examples
Linda Davis, Austin Community College
I give the students analyses from work that I did with Chris Henry on the Bofecillos Mountains and the Solitario. (Tertiary Volcanism of the Bofecillos Mountains and Big Bend Ranch State Park, Texas: Revised ...
Rock Samples and Geochemistry Analyses part of Cutting Edge:Geochemistry:Activities
Maria Rosa Lourdes, Bahia Federal University
We will emphasize the importance of rock sampling and preparation for geochemistry analyses.
Crystallization-Differentiation of Basaltic Magma part of Cutting Edge:Geochemistry:Activities
Kent Ratajeski, University of Kentucky
In this exercise, students use geochemical data from volcanic glasses and minerals in lavas and drill cores from the solidified Kilauea Iki lava lake to learn about the petrologic processes related to the eruption ...
