Compatibility Diagram 1: Dsp-Py-Qz-Ka-H2O part of Teaching Examples
Dexter Perkins, University of North Dakota-Main Campus
One of three compatibility diagrams I use in class. This is a short activity to introduce students to compatibility diagrams (triangular diagrams showing stable assemblages) and how tie lines change when a reaction ...

Outcrop Mapping at Woodall Shoals, South Carolina-Georgia part of Cutting Edge:Geoscience in the Field:Activities
Jonathan Mies, University of Tennessee-Chattanooga, The
Students work in groups of 3 or 4 to map relatively small parts of the outcrop at Woodall Shoals, which serves as a model of a complexly deformed high-grade metamorphic terrain. With the benefits of 100% exposure ...

Recognizing and mapping faults using lidar and field data part of Cutting Edge:Structural Geology:Structure, Geophysics, and Tectonics 2012:Activities
Anne Egger, Central Washington University
In this activity, students create a geologic map and cross-section of the Fish Springs cinder cone and surrounding area in the Owens Valley, CA, using a high-resolution DEM developed from airborne lidar data as a ...

Chemical Differentiation in the Palisades Sill part of 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 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 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 ...

Rb-Sr isotope in-class exercise part of Teaching Examples
Allen Glazner
This set of problems involves calculations of changes in radiogenic isotope ratios. It requires students to understand the concept of an isochron and how isotope ratios change (or do not change) during magma mixing ...

Properties of Rhyolite Magma part of Teaching Examples
Barbara Nash
The purpose of the exercise is to acquaint igneous petrology students with properties of silicic magmas, and to emphasize the effect of water content on viscosity of silicic magmas. Students have to determine the ...

Flow of Andesite Lava part of Teaching Examples
Barbara Nash
The purpose of the exercise is to familiarize igneous petrology students with flow properties of lava, especially viscosity, and to have them consider effects on viscosity due to temperature, crystallinity and ...

Interpretation and Petrogenesis of Zoned Plagioclase part of Teaching Examples
R. K. Smith
The purpose of this exercise is to give students the experience of utilizing the two component solid solution phase diagram of albite-anorthite and applying this diagram to the interpretation and petrogenesis of ...

Major Element Control Presentation part of 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 ...

Application of Sr Isotopic Data to Tuolumne Intrusive Series, Sierra Nevada, CA part of Teaching Examples
Jeff Tepper, University of Puget Sound
In this problem set students are given Rb/Sr and 87Sr/86Sr data for whole rock and mineral samples from three granitic intrusions in the Sierra Nevada. They use these data (in EXCEL) to calculate isochron ages and ...

Thermobarometry Problem Set part of Teaching Examples
Jane Selverstone
This homework assignment gives students first-hand experience with thermobarometric calculations. Because many of my students are math challenged, I give them a choice of solving the equations by hand or with ...

Simple Eutectic Exercise: Diopside-Anorthite part of Teaching Examples
Dexter Perkins, University of North Dakota-Main Campus
This exercise can be done in-class (I use it as a group activity) or as homework. It is a quick way to get students to figure out how to use and interpret simple eutectic diagrams.

Major Element Fractionation During Differentiation part of Teaching Examples
Elizabeth King
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 ...
