Petrography and Petrogenesis of a Mid-Ocean Ridge Lava Suite part of Cutting Edge: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 ...
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 ...
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, ...
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. ...
Batch and Rayleigh Decarbonation Modeling of d13C part of Cutting Edge:Petrology:Teaching Examples
Jade Star Lackey, Pomona College;
This is an Excel spreadsheet and graph that illustrates standard "batch" and Rayleigh decarbonation models and how they can be used to detect fluid infiltration during metamorphism of carbonates. It makes ...
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. ...
Homework on Volcanic Rock Chemistry and Binary Phase Diagrams part of Cutting Edge:Petrology:Teaching Examples
Jane Selverstone, University of New Mexico-Main Campus
This homework has 2 main parts: In the first part, students are given bulk compositions for 6 volcanic rocks and asked to classify them, think about their normative compositions, and given likely tectonic settings ...
Major Element Control Presentation part of Cutting Edge:Petrology:Teaching Examples
Kurt Hollocher, Union College (Lincoln, NE)
The presentation is an introduction to the control of magma chemical compositions by the fractionation of crystallizing phases. It is followed by a lab exercise where students interpret volcanic rock petrology and ...
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 ...
Calculating Rb-Sr Isochrons part of Cutting Edge:Petrology:Teaching Examples
Andy Barth, Indiana University-Bloomington
This is a spreadsheet that I use in petrology to walk students through calculating Rb-Sr isochrons and talking about isotope heterogeneity and sampling at various scales. The example exercise is the Tuolumne ...
Geochemistry all around us part of Activities
Andrew Knudsen, Lawrence University
We look at a variety of natural waters in and around Appleton over the course of the term. The goal is for students to recognize differences and how those play into the topics we have covered in the course.
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.
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 ...
REE Modeling of Melting and Crystallization part of Activities
Mark Schmitz, Boise State University
This exercise is used in and out of class for exploring the use of trace elements to model melting and crystallization processes; it emphasizes quantitative skills and constructing numerical models.
Graphing Chemical Data to Identify Fractional Crystallization part of Cutting Edge:Petrology:Teaching Examples
John Brady, Smith College
Students are given major-element, whole-rock chemical analyses from ten samples of lava from the 1868 eruption of Mauna Loa. They do not know sequence of eruption, only that the lavas came from the same volcano. ...
