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 ...
T-X Phase Diagrams part of Cutting Edge:Petrology:Teaching Examples
Dexter Perkins, University of North Dakota-Main Campus
This is a 15 page tutorial and problem set designed to get students familiar with T-X diagrams, their implications, and uses.
Heat Capacity of Minerals: A Hands-On Introduction to Chemical Thermodynamics part of Cutting Edge:Mineralogy:Activities
David Bailey, Hamilton College
Minerals are inorganic chemical compounds with a wide range of physical and chemical properties. Geologists frequently measure and observe properties such as hardness, specific gravity, color, etc. Unfortunately, ...
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 ...
Timing of mineralization in the palm of your hand: Cross-cutting relations, copper minerals and ore-forming hydrothermal fluid evolution part of Cutting Edge:Petrology:Teaching Examples
Barb Dutrow, Louisiana State University
This lab is designed to familiarize students with the geologic history of an ore-deposit, deciphered in the palm of your hand. By determining cross cutting relations of veins and mineralogy, students decipher the ...
Teaching Stable Isotope Geochemistry in an Undergraduate Petrology or Geochemistry Course part of Cutting Edge:Petrology:Teaching Examples
This assignment includes three reading assignments for students that (1) introduce the basics of stable isotope geochemistry, (2) explain carbon and oxygen isotopic shifts that result from volatilization and/or ...
Marine Oxygen Isotopes and Changes in Global Ice Volume part of Cutting Edge:Climate Change:Activities
Ben Laabs, SUNY College at Geneseo
Students explore marine oxygen-isotope data from cores collected by the Ocean Drilling Program. The activity gives students access to real paleoclimate data, develops their skills in organizing and graphing data, ...
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, ...
Relationship between mineral weathering and groundwater composition part of Activities
Nancy Hinman, University of Montana-Missoula, The
By observing changes in rocks exposed to chemical weathering, students are to infer resulting changes to the chemical composition of groundwater. Students are required to justify their inferences through the use of ...
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.
Spreadsheet analysis of chemical hydrographs part of Cutting Edge:Hydrogeology:Activities
This is a good activity to have students practice spreadsheet analysis skills on a medium large data set. It also helps them understand stream hydrographs and baseflow/quickflow components.
Rayleigh fractionation visualization part of Cutting Edge:Climate Change:Activities
E. Christa Farmer, Hofstra University
A MS Excel spreadsheet gives an account of Rayleigh fractionation, the progressive removal of the heavier oxygen isotope as a moist air parcel moves from the subtropics to the high latitudes. This exercise is ...
Teaching the nitrogen cycle and human health interactions part of Cutting Edge:Geology and Human Health:Workshop 04:Activities
Margaret Townsend, University of Kansas Main Campus
This activity uses objects, pictures, and text in a matching game to define the nitrogen cycle and the environmental and human health impacts of nitrogen. The game can be used to associate useful and detrimental ...
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 ...
Rb-Sr isotope in-class exercise part of Cutting Edge:Petrology:Teaching Examples
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 ...
