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 ...
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.
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. ...
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 ...
Crystallization of Magmas part of 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 ...
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.
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.
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 ...
Crystallization-Differentiation of Basaltic Magma part of 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 ...
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. ...
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 ...
